Ozon Data Security Team Details Audit Framework to Eliminate Paper-Only Compliance

Alena, head of the Data Security group at Ozon, describes how the company built an internal audit process that focuses on actual risk reduction instead of producing lengthy formal reports. The team examines personal data, financial records, and other sensitive information across hundreds of microservices while checking role-based access, logging, encryption, and data flows. They analyzed more than 84,000 user-role pairs in one review and identified overly broad permissions on product tagging that could cause major financial losses. A notable case led to the removal of customer names, phones, and addresses from delivery boxes even though the practice was formally allowed under Federal Law 152-FZ. The group uses a scoring model based on data sensitivity, business importance, user count, and potential monetary impact to prioritize which systems to audit first. Additional criteria such as past incidents and critical information infrastructure status can be added to the model. The approach emphasizes real implementation of recommendations, cross-team communication, and hiring analysts who care deeply about practical security outcomes.
