Fluid Attacks SAST is a commercial static application security testing tool by Fluid Attacks. DeepSource SAST is a commercial static application security testing tool by DeepSource. Compare features, ratings, integrations, and community reviews side by side to find the best static application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Development teams moving fast in CI/CD pipelines need Fluid Attacks SAST primarily for its reattack validation feature, which actually verifies that fixes work rather than just flagging them as closed. The tool covers 13+ languages with native Git OAuth integration across GitHub, GitLab, Azure, and Bitbucket, meaning zero friction to drop into existing workflows. Skip this if you need CSPM or IaC scanning as your primary concern; Fluid Attacks treats infrastructure-as-code as secondary to source code vulnerability detection.
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.
