Bearer vs Flawfinder

Bearer CLI is a free static application security testing tool for Linux and macOS. It scans source code and analyzes data flows to identify security and privacy risks while analyzing code patterns instead of viewing actual data values. The tool supports more than 120 sensitive data types, including personal data, PII, and PHI. Privacy reports can show sensitive data, related data subjects, and internal or third-party components that process it, with information useful for GDPR records of processing activities. Security features include SAST rules and a separate hard-coded-secrets scanner. Bearer documents pull-request and CI/CD use with GitHub Actions, GitLab CI/CD, and CircleCI, plus custom security rules. Listed stacks include Go, Python, PHP, JavaScript, TypeScript, Ruby, and Java. Installation options include scripts, Homebrew, Linux package managers, Docker, and binaries. macOS 12 or later and Git 2.34 or later are required.

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.
