DeepSource SAST vs DryRun Security AppSec Agents: Side-by-Side Comparison (2026)

Short 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 at startup and mid-market velocity need DryRun Security AppSec Agents to stop spending engineering time triaging false positives from rule-based SAST. Its AI-driven detection reasoning cuts noise by actually explaining exploitability rather than flagging every code pattern, and the pull request-native workflow means security happens where developers already work, not in a separate scanning queue. Skip this if your org needs policy enforcement across sensitive file changes as a hard gate; the allowed authors feature exists but this tool prioritizes finding real bugs over access control workflows.
