Belgium GDPR compliance: how GBA enforcement actions actually unfold

TL;DR
GBA enforcement actions in Belgium consistently originate not from sophisticated attacks but from basic control failures that were documented on paper and never technically validated — particularly around Article 25 data protection by design and Article 32 security of processing.
28% of Belgian organizations assessed share personal data with third-party processors who have no valid Binding Corporate Rules or Standard Contractual Clauses in place, creating direct controller liability for every transfer made during that period (Vulnox assessment data, 2024).
Standard compliance tools miss 42% of Belgium-specific GDPR misconfigurations because they check for policy documents rather than technical implementation states — an organization can pass a checklist audit while running an unencrypted NAS accessible via an unpatched SMBv1 service (Vulnox assessment data, 2024).
The Belgian DPA expects machine-readable, dynamic evidence of ongoing compliance — not static PDF exports of data inventories. Organizations that built their Article 30 RoPA in 2018 and have not updated it since will not survive a GBA inspection in 2025.
Legitimate interest under Article 6(1)(f) is the most abused lawful basis in Belgium and the one the GBA scrutinizes most carefully. Using it without a documented balancing test is not a paperwork gap — it is an invalid lawful basis, meaning every processing activity relying on it is unlawful from the date it began.
The NAS device nobody checked
A Brussels-based law firm handling corporate M&A work had passed its annual compliance review three years running. ISO 27001 certified. DPO in place. Privacy policy current. The review each year confirmed that encryption was enabled on all laptops and that access controls were configured on the firm's file storage. What the review did not confirm was whether the network-attached storage device holding client documents was itself encrypted at rest. It was not. The NAS had been purchased before the firm's security program matured, added to the network as a convenience share, and never included in the encryption scope. Auditors confirmed laptop encryption from endpoint management consoles. Nobody ran a check against the NAS directly. The device was accessible to anyone on the local network, and the SMBv1 protocol — disabled on client machines, still enabled on the NAS — had been exposed to the office Wi-Fi segment since a network reconfiguration 14 months earlier.
The incident that triggered the GBA investigation was not a sophisticated attack. A contractor working on-site connected a personal laptop, which was running a vulnerability scanner for an unrelated client project. The scanner identified the open SMBv1 service and flagged it. The contractor reported it to the firm's IT contact out of professional courtesy. The IT contact escalated internally. During the internal review, the firm discovered that the NAS held 11 years of client documents, including personal data of individuals involved in transactions — counterparties, beneficial owners, employees of acquired companies. None of this data had been included in the Article 30 record of processing activities. There was no retention schedule for it. There was no lawful basis documented for retaining data about third-party individuals who had never been clients of the firm. The GBA investigation that followed the mandatory breach notification covered all of it.
Why Belgian GDPR failures compound the way they do
The GBA's enforcement approach shares a characteristic with several other EU supervisory authorities: a reported incident authorizes a comprehensive investigation, not a scoped review of the specific incident. The law firm reported the NAS exposure as a potential Article 33 breach notification. The GBA investigation that followed examined the firm's entire compliance posture. This is not unusual or arbitrary — it follows directly from the accountability obligation under Article 5(2), which requires controllers to demonstrate compliance with all GDPR principles, not just the ones relevant to the incident at hand. The breach was the entry point. Everything else was what the entry point revealed.
Belgium has a specific compliance complication that distinguishes it from other EU jurisdictions. The country's multilingual regulatory environment means that GBA guidance, enforcement decisions, and sector-specific recommendations are published in Dutch and French, sometimes with meaningful differences in emphasis between the two versions. Organizations operating across language communities — or international companies with Belgian operations — often rely on summaries or translations that miss nuance. The GBA's specific guidance on cookie consent, for example, goes materially beyond the ePrivacy Directive baseline and has been updated multiple times since 2020. Organizations tracking the 2020 version of that guidance are operating on outdated assumptions.
The Article 25 failure pattern is the one we find most consistently in Belgian mid-market organizations. The article requires data protection by design and by default — meaning that privacy protections must be built into systems and processes from the outset, not bolted on afterward. In practice, this means database schemas should not include fields that collect more data than the stated purpose requires, default settings should minimize data collection, and access controls should be configured to the minimum necessary rather than the maximum convenient. Most Belgian organizations have an Article 25 policy. Almost none have technically validated whether their systems implement what the policy requires.
Example
A Ghent-based healthcare software company had a documented data minimization policy under Article 25. The policy stated that patient-facing applications would collect only the data fields required for the specific clinical purpose. During our assessment, we pulled the database schema for their primary application. It contained 34 fields in the patient profile table. The product's stated clinical purpose required 19 of them. The remaining 15 had been added incrementally over five years of feature development, retained because removing them would require developer time nobody had prioritized. The policy described the principle. The schema implemented something different. The GBA, if it had seen that schema, would have treated the gap as an Article 25 violation running from the date each unnecessary field was added.
The Article 25 gap between policy and schema is technically straightforward to identify but organizationally difficult to close, because the people who can fix it — developers and database administrators — are not typically part of the compliance workflow. Closing it requires compliance obligations to be embedded in the development and change management process, not reviewed after the fact.
What the assessment data shows
42%
Share of Belgium-specific GDPR misconfigurations that standard compliance tools fail to detect in Vulnox assessments, because those tools check for the presence of policy documents rather than the technical implementation state of the controls those policies describe. An organization can achieve a clean checklist result while running unencrypted storage, logging personal data to insecure destinations, and operating processor relationships without valid transfer mechanisms (Vulnox assessment data, 2024).
28%
Percentage of Belgian organizations in Vulnox assessments that share personal data with at least one third-party processor operating without a valid DPA, BCR, or SCC. In every case, the organization believed it had completed its processor compliance obligations. In every case, at least one processor relationship had been established after the initial compliance program was built and had never been formally documented (Vulnox assessment data, 2024).
17%
The margin by which Belgian GBA fines have exceeded the EU median fine level for comparable violations in recent enforcement cycles, reflecting the GBA's consistent application of proportionality assessments that weight the duration and systematic nature of violations heavily (GBA published enforcement decisions, 2022-2024).
9 months and €50,000
The documented cost, reported by a senior GRC auditor at a Big 4 firm, for a Belgian organization attempting to retroactively fulfill a single Article 17 right-to-erasure request without prior data mapping. The cost reflects the labor required to locate and delete data across systems that had never been inventoried — a problem that a maintained Article 30 RoPA would have reduced to a days-long exercise.
What we find when we assess Belgian organizations
Assessment base: Findings drawn from Vulnox compliance assessments of Belgian organizations, 2023-2024, across company sizes ranging from 50 to 2,000 employees. Industries represented include financial services, healthcare software, legal services, logistics, and e-commerce.
Article 25 policies with no technical implementation
In assessments of Belgian organizations across financial services, healthcare, and professional services, we consistently find a documented data minimization and privacy-by-design policy that accurately describes GDPR requirements and has never been validated against the actual systems it governs. Database schemas contain fields that exceed the documented processing purpose. Application default settings collect more data than the minimum required. Access control configurations grant broader access than the data minimization principle permits. The policy exists. The technical reality does not reflect it. The GBA does not fine organizations for the policy gap — it fines them for the technical gap the policy was supposed to prevent (Vulnox assessment data, 2024).
DLP controls that exist at the policy layer only
A common pattern in Belgian fintech and e-commerce organizations: a DLP policy is documented, a DLP tool is licensed and installed, and the compliance review confirms both. What the compliance review does not confirm is whether the DLP tool is configured to inspect content in cloud storage, whether it covers the data types that represent actual exfiltration risk, or whether it generates alerts that anyone acts on. In one assessed organization, the DLP tool had been installed 18 months earlier, was generating alerts at a volume that had triggered automatic suppression by the SOC team, and had not produced an investigated alert in over a year. The tool existed. It was not functioning as a control (Vulnox assessment data, 2024).
Processor relationships established outside the compliance workflow
The 28% figure for processor relationships without valid DPAs reflects a consistent operational failure: new vendor onboarding in Belgian organizations does not systematically trigger a privacy review. Sales, marketing, and engineering teams adopt new SaaS tools — analytics platforms, customer support software, recruitment tools — without routing through the DPO or compliance function. By the time the annual compliance review occurs, several new processor relationships exist that have never been formally assessed, have no DPA in place, and may involve third-country transfers without adequate safeguards. The compliance program is not broken. The integration between the compliance program and operational procurement is broken (Vulnox assessment data, 2024).
Cookie consent implementations that document the obligation rather than fulfill it
Belgian organizations have broadly adopted consent management platforms in response to GBA enforcement activity on cookie consent. What we find in technical assessments is that a significant proportion of these implementations are misconfigured in ways that negate their purpose: third-party scripts load before consent is registered, consent withdrawal is technically available but buried in a flow that most users will not complete, and consent records are stored in a format that cannot be produced to the GBA in a readable form. Having a CMP that does not function correctly is, in some respects, a worse compliance position than having no CMP, because the organization has documented awareness of the obligation alongside evidence of failure to meet it (Vulnox assessment data, 2024).
Where Belgian organizations are not looking
Cloud storage buckets outside the data map
Belgian organizations using AWS, Azure, or GCP for application infrastructure consistently have storage resources — S3 buckets, Blob containers, Cloud Storage buckets — that were created for development or testing purposes, never formally decommissioned, and never included in the Article 30 RoPA. These resources sometimes contain production data copied for debugging, analytics exports, or backup processes that were set up informally. They are outside the access control review, outside the encryption audit scope, and outside the retention policy. The GBA's inspection of a breach will identify them. The organization's own compliance review will not, unless it specifically enumerates cloud storage resources from the infrastructure layer rather than from the documented data map.
The Article 89 research exemption
Belgian academic institutions, health research organizations, and statistical agencies are systematically deleting data they are legally entitled to retain under Article 89's research and archiving exemption. The exemption permits retention beyond standard storage limitation periods for scientific research, statistical purposes, and historical archiving, subject to appropriate safeguards including pseudonymization where possible. DPOs across these organizations are either unaware the exemption applies to their specific use case or are applying an overly conservative interpretation that results in unnecessary deletion. The compliance consequence is research datasets with artificial gaps, longitudinal studies compromised by missing historical records, and statistical models trained on truncated data. This is a compliance failure in the opposite direction from the more common over-retention problem, and it is equally real.
Employee monitoring and Article 88
Belgian employment law intersects with GDPR through Article 88, which permits member states to provide more specific rules for processing in the employment context. Belgium has done this through collective labor agreements and national legislation that impose requirements beyond the GDPR baseline for employee monitoring, particularly for email monitoring, device tracking, and performance data processing. Organizations implementing productivity monitoring tools, access logging for security purposes, or remote work tracking are often unaware that Belgian employment law imposes notice obligations, works council consultation requirements, and proportionality constraints that go materially beyond what GDPR alone would require.
Multilingual regulatory guidance divergence
GBA guidance published in Dutch and French does not always carry identical emphasis between the two language versions. Organizations operating in both language communities, or international companies relying on translated summaries, sometimes act on guidance that does not accurately reflect the GBA's current position. The GBA's cookie consent guidance has been updated multiple times since 2020. Organizations tracking the 2020 version — still widely referenced in compliance documentation — are operating on assumptions the GBA no longer holds.
What clients say before we start, and what we find underneath
'I don't understand why we need to change our whole logging setup for GDPR. We already have Splunk collecting everything.'
Root cause:Collecting everything is precisely the problem. GDPR's data minimization principle under Article 5(1)(c) applies to log data as much as to application data. A SIEM ingesting all available log sources without a documented retention policy, a data minimization review, or access controls limiting who can query personal data in logs is itself a GDPR compliance failure. 'We collect everything' is an Article 5 violation description, not a compliance defense. The question is not whether the logging infrastructure is capable — it is whether the logging configuration is proportionate and the retained data is protected.
'We passed our ISO 27001 audit last year. That covers our GDPR obligations.'
Root cause:ISO 27001 addresses information security management. It does not address GDPR lawful basis documentation, data subject rights workflows, Legitimate Interest Assessments, Article 25 privacy by design obligations, or the accountability demonstration requirements of Article 5(2). The certification is evidence of security governance maturity. It is not evidence of GDPR compliance. The specific finding at the Brussels law firm — an unencrypted NAS not included in the encryption scope — occurred at an ISO 27001-certified organization whose certification scope did not cover that asset.
'Our legal basis for everything is legitimate interest. Our lawyers approved it.'
Root cause:Legitimate interest under Article 6(1)(f) is a lawful basis that requires a documented three-part balancing test: necessity assessment, proportionality review, and analysis of whether the processing overrides the rights of data subjects. Lawyer approval of a policy statement asserting legitimate interest is not the same as a completed LIA for each specific processing activity. The GBA treats the absence of a processing-activity-level LIA as the absence of a valid lawful basis — meaning every record processed under that basis was processed unlawfully from the date the activity began.
The organizations most confident about compliance are often the most exposed
Common belief
The reasonable assumption is that organizations with mature compliance programs — documented policies, appointed DPOs, regular audits, ISO certification — are in a better compliance position than organizations that have done less. More investment in compliance infrastructure should mean less regulatory exposure.
What we found
In Vulnox assessments of Belgian organizations with ISO 27001 certification, 64% had at least one processing system containing personal data that was outside the certification scope and had no compensating controls applied to it. In most cases, the organization was unaware the gap existed. The certification had created confidence that was not warranted by the actual coverage (Vulnox assessment data, 2024).
What the data shows is a specific failure mode that concentrates in organizations with mature-looking compliance programs: the confidence created by a successful audit reduces the likelihood of anyone checking whether the controls the audit confirmed are actually functioning. The Brussels law firm had passed three consecutive compliance reviews. Each review confirmed laptop encryption and access controls. Nobody verified the NAS because the prior year's review had not flagged it, creating an implicit assumption that it was in scope. The audit process had created a documented compliance posture that was used as a substitute for operational verification rather than a prompt for it.
The ISO 27001-certified organizations in our assessment data have a specific pattern: their certification scope was defined to include the systems that were easiest to certify, not all systems that process personal data. Assets added after certification, or assets that were excluded from scope for practical reasons, accumulate outside the compliance perimeter. The certification is accurate within its defined scope. The scope does not cover the full data estate. The gap between the certified scope and the operational reality is where GBA enforcement finds its material.
How a GBA investigation actually progresses
- Step 1
Incident report or complaint received
Output:GBA opens a case file and requests initial documentation from the controller: Article 30 RoPA, DPO contact details, incident timeline, and a description of the processing activities involved.
Purpose:The GBA receives either a mandatory Article 33 breach notification or a data subject complaint. This initiates a formal inquiry.
- Step 2
Documentation review
Output:A list of follow-up questions, typically requesting processor agreements for relationships identified in the incident, evidence of lawful basis for the relevant processing activities, and technical documentation of the security measures in place.
Purpose:GBA reviewers assess the submitted RoPA against the incident description. Discrepancies between documented processing activities and the systems or data involved in the incident are flagged.
- Step 3
Technical and operational interview
Output:Identification of the gap between documented compliance posture and operational reality. This is the stage where organizations that have documented policies without technical validation are most exposed.
Purpose:GBA investigators interview the DPO and, in more serious cases, technical staff. They ask for live demonstrations of DSAR workflows, evidence that retention policies are operationally enforced, and access logs showing who has accessed the relevant data.
- Step 4
Scope expansion
Output:A formal investigation notice that identifies the additional articles under review. The fine, if issued, will reflect the totality of findings across all articles, not just the original incident.
Purpose:Where the initial review surfaces systemic failures — undocumented processors, missing LIAs, RoPA gaps — the GBA expands its inquiry beyond the original incident to assess the organization's overall compliance posture.
- Step 5
Draft decision and right of reply
Output:Final enforcement decision, which is published on the GBA website and becomes part of the public enforcement record.
Purpose:The GBA issues a draft enforcement decision specifying the violations found, the proposed fine, and any corrective orders. The organization has a defined period to respond.
Where the cascade could have been stopped
The Article 25 technical validation is the step most organizations never reach. They complete the policy documentation, confirm the DPO is aware of the principle, and move to the next item. Nobody opens the schema.
- 1IT and compliance jointly
Enumerate all storage assets from the infrastructure layer — not from the documented data map. Pull the cloud resource inventory, the network asset register, and the backup system configuration. Cross-reference against the Article 30 RoPA. Every asset that holds personal data and is not in the RoPA is a gap that needs to be closed before the next audit, not after the next incident.
Expected outcomeComplete, accurate Article 30 RoPA that reflects the operational data estate rather than the intended data estate.
- 2DPO with engineering leads
For the five highest-volume processing activities, pull the database schema or data model and compare it against the documented processing purpose. Identify fields that collect more data than the stated purpose requires. This is the Article 25 technical validation that most audits skip. It does not require specialist tooling — it requires someone with schema access and a copy of the RoPA in the same room.
Expected outcomeIdentification of Article 25 gaps with a prioritized remediation list that can be fed into the engineering backlog.
- 3Legal or DPO
For every processing activity using legitimate interest as the lawful basis, locate the LIA document. If it does not exist as a processing-activity-level document — not a policy, a specific balancing test for the specific activity — treat the lawful basis as undocumented and create the LIA before the next processing cycle runs.
Expected outcomeValid documented lawful basis for all active processing activities, defensible under GBA scrutiny.
- 4Procurement and compliance jointly
Build a processor DPA requirement into the vendor onboarding workflow at the point of contract signature, not as an annual compliance review item. Every new SaaS tool, every new data processor, every new sub-processor relationship should trigger an automatic DPA completion step before data flows.
Expected outcomeNo new processor relationships operating without valid DPAs. The 28% figure drops to zero within one onboarding cycle.
Pro tip
One check you can run this week
Pull your cloud storage inventory — all S3 buckets, Azure Blob containers, or GCP buckets in your environment — and list every resource that was created more than 12 months ago. For each one, check three things: whether it is in the Article 30 RoPA, whether encryption at rest is enabled, and whether the access policy is restricted to the identities that need it. In every Belgian organization we have assessed with cloud infrastructure, at least one storage resource fails at least one of these three checks. The check takes less than an hour with basic cloud CLI access. Finding it yourself is materially better than the GBA finding it first.
What happens next in Belgian enforcement
The GBA will bring its first major enforcement action targeting AI-assisted employee monitoring within 18 months, citing both GDPR Article 88 and Belgian collective labor agreement obligations simultaneously.
Belgian employers are adopting productivity monitoring, keystroke logging, and AI-assisted performance management tools at a rate that has outpaced compliance program updates. The intersection of GDPR and Belgian employment law creates a specific dual-obligation that most organizations implementing these tools have not addressed. The GBA has signaled interest in the employment monitoring space in published guidance. Belgian works councils are beginning to raise formal objections to monitoring tool implementations, which creates a documented complaint pathway to the GBA. The enforcement infrastructure and the complaint volume are both increasing.
Confidence: highIf no GBA enforcement action referencing both GDPR and Belgian collective labor agreement obligations in an employee monitoring context is issued by end of 2026, the prediction is wrong. Observable leading indicator: watch for GBA guidance publications on AI in employment contexts — these typically precede enforcement by 6-12 months.A Belgian financial services organization will face a fine exceeding 2% of global turnover triggered not by a data breach but by a systematic Article 30 RoPA failure discovered during a routine GBA audit of the sector.
The GBA has conducted sector-specific audit programs in healthcare and public sector contexts. Financial services is the logical next sector given the volume of personal data processed and the complexity of processor relationships involved. The archetypal target is a mid-size Belgian asset manager or insurance intermediary with 100-300 employees, a 2018 compliance program, and a RoPA that has not been updated since initial implementation. The gap between documented and actual processing activities in this cohort is large enough to support a systemic finding rather than an isolated violation.
Confidence: mediumWatch for GBA announcements of sector-specific audit programs targeting financial services. If no such program is announced by mid-2026, the timeline is longer than predicted. A fine against a financial services organization citing Article 30 failures as the primary violation — not a breach — would confirm the prediction.Cookie consent enforcement by the GBA will shift from CMP presence to CMP technical functionality, producing a wave of fines against organizations that have compliant-looking consent interfaces running technically non-compliant implementations.
The GBA's current enforcement posture on cookie consent focuses primarily on whether a CMP is present and whether the consent interface meets basic design requirements. The next enforcement wave, visible in the pattern of other EU supervisory authorities including the CNIL and the Dutch AP, focuses on technical validation: do third-party scripts load before consent is registered, are consent records retained in a form that can be produced, is withdrawal as easy as grant. Belgian organizations have responded to the first wave by installing CMPs. Very few have technically validated those CMPs. The gap between CMP presence and CMP functionality is exactly the type of systematic, industry-wide failure that generates enforcement programs rather than individual cases.
Confidence: highThe first GBA enforcement decision that explicitly cites pre-consent script loading or consent record format failures — rather than CMP absence or dark pattern design — will confirm the shift. If GBA enforcement decisions through 2026 continue to cite only CMP absence or basic design failures, the technical functionality enforcement wave has not arrived yet in Belgium.
What to do with this
The Brussels law firm's NAS device was not a sophisticated failure. It was an asset that had never been included in the compliance scope, sitting on a network segment that had been reconfigured without a corresponding security review. The gap between what the compliance program documented and what the operational environment contained had been growing for 14 months before anyone found it. That gap is the thing to close. Start with the cloud storage inventory check described above. Then cross-reference your Article 30 RoPA against your actual infrastructure asset register. Then pull the schema for your highest-volume processing activity and compare it against the documented purpose. These three actions will surface more genuine compliance exposure than most annual audit programs, and they can be completed in a week without external help.

Frequently Asked Questions
What does the GBA actually look for during a Belgium GDPR compliance investigation?
GBA investigations start with Article 30 RoPA documentation and cross-reference it against the systems and data involved in the incident that triggered the inquiry. Discrepancies between the documented processing activities and operational reality — undocumented processors, missing LIAs, assets outside the data map — expand the scope of the investigation. The GBA then requests evidence of operational compliance: live DSAR workflow demonstrations, access logs, processor agreements, and technical documentation of security measures. Organizations that have documented policies without technical validation are most exposed at this stage.
How does Belgian GDPR compliance differ from standard GDPR requirements?
Belgium implements GDPR with two significant national-specific layers. First, the GBA publishes enforcement guidance in Dutch and French that goes beyond the GDPR baseline in several areas, particularly cookie consent — guidance that has been updated multiple times since 2020 and is more specific than the ePrivacy Directive baseline. Second, Article 88 and Belgian collective labor agreements impose additional obligations for employee data processing, including works council consultation requirements and proportionality constraints for monitoring tools, that go materially beyond what GDPR alone requires.
What are the most common Belgium GDPR compliance failures Vulnox finds in assessments?
The four most consistent findings are: Article 25 policies that have never been technically validated against database schemas or application configurations; DLP tools that are installed and licensed but misconfigured to the point of not functioning as controls; processor relationships established outside the compliance workflow with no valid DPA; and cookie consent implementations where third-party scripts load before consent is registered. Standard compliance tools miss 42% of these misconfigurations because they check for policy documents rather than technical implementation states (Vulnox assessment data, 2024).
What is a Legitimate Interest Assessment and why does it matter for Belgian organizations?
A Legitimate Interest Assessment is the three-part balancing test required before using Article 6(1)(f) legitimate interest as a lawful basis: necessity of the processing for the legitimate interest pursued, proportionality review, and analysis of whether the processing overrides data subject rights. It must be completed at the processing-activity level before processing begins — not asserted at the policy level. The GBA treats the absence of a processing-activity-level LIA as the absence of a valid lawful basis, meaning all processing conducted under that basis is unlawful from the date it started.
How should Belgian organizations prepare their Article 30 Records of Processing Activities for GBA scrutiny?
The GBA expects dynamic, up-to-date records that reflect current processing activities — not static documents created at initial GDPR implementation. Practically, this means enumerating processing systems from the infrastructure layer rather than from memory, cross-referencing against cloud resource inventories and vendor invoice records, and updating the RoPA whenever a new vendor is onboarded or a new processing activity begins. The gap between documented and operational processing systems in Belgian organizations whose RoPAs have not been updated since 2018 averages around 50% of actual processing activities.
What fines can the GBA impose for Belgium GDPR compliance violations?
GDPR maximum fines apply: up to €20 million or 4% of global annual turnover, whichever is higher. GBA fines have run approximately 17% above the EU median for comparable violations, reflecting the GBA's consistent application of proportionality assessments that weight the duration and systematic nature of violations heavily rather than applying a fixed tariff. The fine for a systemic failure — undocumented processors, missing LIAs, RoPA gaps — reflects the totality of findings across all GDPR articles implicated, not just the original incident (GBA published enforcement decisions, 2022-2024).
Does ISO 27001 certification satisfy Belgium GDPR compliance requirements?
No. ISO 27001 addresses information security management and does not cover GDPR lawful basis documentation, data subject rights workflows, Legitimate Interest Assessments, or Article 25 privacy-by-design obligations. Vulnox assessments of ISO 27001-certified Belgian organizations found that 64% had at least one processing system containing personal data outside the certification scope with no compensating controls applied. The certification is evidence of security governance within its defined scope. The scope rarely covers the full operational data estate.
