Perforce Klocwork is a commercial static application security testing tool by Perforce Software. 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 shipping C, C++, and Java at scale will get the most from Perforce Klocwork because its differential analysis mode catches regressions in changed code without slowing down the build pipeline. It supports MISRA C/C++ and AUTOSAR C++ 14 out of the box, which matters if you're embedded systems or automotive; most SAST tools treat safety standards as an afterthought. Skip this if your codebase is predominantly Python or JavaScript and you need deep data flow analysis for third-party dependencies, where Klocwork's strength in compiled languages becomes a liability.
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.
