In their own words
Flawfinder
Flawfinder is a free tool for finding possible security weaknesses in C and C++ source code. It compares source text with a built-in database of functions associated with security problems, generally disregarding comments and strings except for Flawfinder directives. Findings are ordered by risk, which depends on the function and its parameter values; the tool may reduce some false positives when it identifies a construct as not risky. Reports can be generated as text, HTML, CSV, or SARIF. The --patch option narrows findings to changed lines in a unified diff, with a one-line margin. Installation is documented through pip, source downloads, and distribution packages, and the tool requires Python 2.7 or Python 3. The project says it works on Unix-like systems, including GNU/Linux, and on Windows with Cygwin; direct Windows use has also been reported to work. Flawfinder is released under GPL-2.0+. It does not perform control-flow or data-flow analysis, so its output is an aid to review rather than a substitute for security knowledge or human judgment.
NaiveSystems Analyze
NaiveSystems Analyze is a static analysis tool for finding security issues in source code and checking compliance with functional safety and coding standards. It uses syntax trees, symbolic execution, and context-sensitive interprocedural data-flow analysis to identify issues such as null pointer dereferences, memory leaks, tainted data, and buffer overflows. Filters, suppressions, and baselines help teams focus on critical defects, while diagnostics are intended to help address severe issues. Listed standards include MISRA C:2012, MISRA C++:2008, AUTOSAR C++14, the complete CERT C and C++ rule set, CWE Top 25, and OWASP Top 10 coverage. The displayed DevOps integrations include GitHub, GitLab, Gerrit, Jenkins, and Buildbot. A free, open-source runner and containerized analyzers support on-premises deployment; the vendor says this keeps source code and privacy under the user's control. The Free plan supports GCC and Clang, up to 100,000 lines of code, and up to four CPUs on one node. Windows and macOS support is for Enterprise customers. The vendor says analyzers for languages beyond C and C++ are in development.
