What problem does it solve?

Security by design helps teams embed security from the outset, preventing insecure designs and costly retrofits.

Core Features & Use Cases

  • Secure by Default: Systems should be secure in their default configuration, default to HTTPS, least privilege, encrypted communications.
  • Defense in Depth: Multiple layers of protection spanning network, application, access control, data, and monitoring.
  • Least Privilege: Minimal permissions for users, processes, and services; scoped credentials; MFA.
  • Fail Securely: Failures do not leak data or weaken security; robust error handling and secure failure modes.
  • Don't Trust User Input: Validate and sanitize all external input; use parameterized queries and proper encoding.
  • Keep Security Simple: Rely on well-tested libraries; minimize surface area and dependencies.
  • Separation of Duties: Code reviews, separate dev/prod environments, audit trails.
  • Economy of Mechanism: Keep security mechanisms simple and leverage standard protocols.

Quick Start

Integrate security-by-design from project kickoff by defining threat models, enforcing secure defaults, and layering defenses across the stack.
