As SaaS platforms grow, they become increasingly attractive targets. Security cannot be an afterthought — it must be foundational. Here are the essentials every SaaS company should have in place.

Authentication & Authorization

Implement multi-factor authentication, use OAuth 2.0 / OpenID Connect for federated identity, enforce strong password policies, and design your authorization model with the principle of least privilege.

Secure Development Lifecycle

Integrate security into every phase: threat modeling during design, static analysis in CI/CD, dependency scanning, regular penetration testing, and security code reviews. Automate everything you can.

Incident Response

Have a documented incident response plan before you need it. Define roles, communication channels, containment procedures, and post-mortem processes. Run tabletop exercises to ensure your team knows what to do when — not if — an incident occurs.
