CST VerdictShort answer
Startup development teams shipping fast need Perisai Web Scanner because it catches vulnerable dependencies and misconfigured headers in minutes without requiring infrastructure changes. The free tier covers automated scanning across JavaScript libraries and HTTP security posture, removing the cost barrier that usually delays security scanning adoption. Skip this if you're managing legacy monoliths with hundreds of interconnected services or need continuous runtime monitoring post-deployment; Perisai maps application risk at scan time, not in production. Startups and early-stage scaleups shipping fast will get the most from DeepSource SAST because it catches security flaws in your pull requests before they reach production, without slowing your CI/CD pipeline; the five-minute GitHub/GitLab integration and per-commit scanning mean you're finding vulnerabilities hours instead of weeks after code lands. The tool runs thousands of checks per scan and addresses both the Identify and Protect functions of NIST CSF 2.0, covering risk assessment and platform hardening in one pass. Skip this if you need post-deployment runtime detection or threat hunting; DeepSource stops at the gate and doesn't follow vulnerabilities into staging or production environments.
