GDPR Penetration Testing Providers
General Data Protection Regulation · Europe
The GDPR is the European Union's comprehensive data protection regulation that applies to any organisation processing personal data of EU residents. Article 32 requires organisations to implement appropriate technical and organisational measures to ensure a level of security appropriate to the risk, including a process for regularly testing, assessing, and evaluating the effectiveness of security measures.
Penetration testing directly supports GDPR compliance by providing evidence of regular security testing and assessment. Article 25 (data protection by design and default) further supports the need for security testing during development and deployment of systems processing personal data. In the event of a data breach, organisations that can demonstrate regular penetration testing and remediation are in a stronger position during regulatory investigations.
The GDPR's potential fines of up to 4% of global annual turnover make proactive security testing a cost-effective risk management measure. Penetration testing for GDPR compliance should cover all systems processing EU personal data, with particular attention to web applications, APIs, and data storage systems.
