We implement row-level security, encryption at rest and in transit, and role-based access controls for SaaS companies data. Audit trails log every access and modification for regulatory review.
SaaS companies 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 SaaS companies regulatory requirements at every CI/CD stage — so compliance issues are caught before code reaches production.
Post-launch, we monitor for compliance drift with automated alerts on access patterns, data flows, and configuration changes. Quarterly compliance reviews are included in our maintenance agreements.
