Former Employees Retain Data Access, Costing Polish Sub-Processor GDPR Fine

Written by AI from the linked story. Not reviewed by an editor. How this works

The core failure in this case was the absence of a reliable offboarding process to revoke former employees' access to systems containing customer personal data. By allowing ex-staff to retain access through a shared application, the sub-processor directly violated GDPR principles of integrity, confidentiality, and accountability. This incident also highlights the controller's responsibility to actively oversee its processors — not merely sign data processing agreements and step back. Supply chain data governance is a two-way obligation: controllers must audit processor compliance, and processors must enforce internal controls rigorously. Regulators are increasingly holding the entire data processing chain accountable, meaning a weak link at the sub-processor level can trigger fines and reputational damage across the chain.

Tactical Insight

Immediate actions

  • Audit all active user accounts against current employee records and immediately revoke access for any former staff.
  • Enforce a formal, documented offboarding checklist that includes same-day revocation of application and data system access.

Long-term improvements

  • Implement automated identity lifecycle management (ILM) tools that deprovision access automatically upon HR system termination events.
  • Establish contractual audit rights and periodic compliance reviews for all data processors and sub-processors.
  • Apply the principle of least privilege so employees only ever access the minimum personal data required for their role.

Detection & oversight measures

  • Schedule quarterly access reviews (access recertification) across all systems handling personal data.
  • Require sub-processors to submit regular evidence of access control audits as part of ongoing controller oversight obligations.

Back this up with a control

All controls and vendors

Training helps people spot this. These controls make the attack fail even on the day someone does not.
