CST VerdictShort answer
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. Development teams shipping code across 30+ languages need Semgrep Code because it catches vulnerabilities in pull requests before merge, not in staging; the AI-powered triage cuts false positives by filtering GPT-4 findings through 900+ high-confidence rules, so developers actually fix real issues instead of ignoring alerts. Scans complete in under five minutes with native GitHub and GitLab integration, meaning security checks won't become a bottleneck in your CI/CD. Skip this if your primary concern is runtime or infrastructure risk; Semgrep Code prioritizes the ID.RA and PR.PS phases where developers can still act, not post-deployment detection.
