SaaS CTO Security Checklist

Based on practical guidance for SaaS CTOs securing both their product and their company across bootstrap, startup, and scaleup stages.

Security requirements change as SaaS companies grow. What works early breaks later. This checklist helps CTOs focus on the right controls at the right stage, without turning security into overhead.

It is built to be used, revisited, and automated as teams scale.

This checklist covers:

Company and team foundations
Core controls like 2FA, email security, access management, onboarding and offboarding, and basic security hygiene that prevent the most common breaches.

Infrastructure and cloud security
Practical guidance on backups, cloud account separation, monitoring, budget alerts, and reducing blast radius as infrastructure grows more complex.

Application and code security
How to handle secrets, dependencies, supply chain risk, secure code reviews, and common vulnerabilities introduced during development.

AI and modern attack surfaces
Checks for LLM usage, AI-related risks, phishing, and newer attack patterns that traditional checklists often miss.

Each item is tagged by company stage so CTOs can apply what matters now and plan for what comes next.
