Data Governance
We implement row-level security, encryption at rest and in transit, and role-based access controls for marketplace platforms data. Audit trails log every access and modification for regulatory review.
Secure Architecture
marketplace platforms systems we build use VPC isolation, encrypted secrets management, and automated vulnerability scanning. For AI features, we add PII redaction in prompts and on-premise model hosting when required.

Compliance is tested, not assumed. We run automated checks for marketplace platforms regulatory requirements at every CI/CD stage — so compliance issues are caught before code reaches production.
