  • Set scope for external penetration tests and bug bounty programs, direct testers, assess severity, and close the remediation loop.
  • Identify recurring vulnerability patterns and eliminate root causes through secure defaults, reusable patterns, and engineering fixes.
  • Write custom static-analysis rules for organizational anti-patterns.

Requirements
