Security as a design constraint

Security added at the end costs several times security designed at the start — and usually doesn't hold.

Most vulnerabilities we find in reviews are not clever exploits. They are direct consequences of early architectural decisions: a permission broader than needed, a secret stored somewhere reachable, or trust placed in an input that was never validated.

What we apply by default

  • Least privilege for every service and every user.
  • Input validation at the boundary, not only deep inside.
  • Encryption at rest and in transit, without exception.
  • An immutable audit trail on every sensitive action.
  • Automated dependency review on every build.
