Built for Fintech Challenges

Regulatory pressure is constant

PCI-DSS audits, SOX compliance, state regulations — one vulnerability can mean millions in fines.

diffray's Security Agent checks every PR against compliance requirements automatically.

Security can't slow down shipping

Manual security reviews create bottlenecks. Features wait days for security sign-off.

AI reviews complete in minutes, not days. Security feedback is instant, not blocking.

Junior devs don't know financial security

Not everyone understands PCI-DSS. Insecure patterns slip through human review.

diffray teaches security best practices through consistent, educational feedback.

Custom Rules for Your Compliance

Define rules specific to your regulatory requirements. Enforce PCI-DSS patterns, prevent insecure payment flows, and ensure consistent security practices.

  • Enforce encryption for all PAN data
  • Require audit logging on transactions
  • Block hardcoded credentials patterns
  • Validate secure API authentication
