vaf vs InternalBlue: 2026 Comparison
vaf is a free penetration testing tool. InternalBlue is a free penetration testing tool. Compare features, ratings, integrations, and community reviews side by side to find the best penetration testing fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers who need to rapidly iterate fuzzing payloads across multiple endpoints will appreciate vaf's speed and cross-platform portability; the lightweight Nim implementation outpaces Python-based fuzzers on CPU-constrained lab environments by 3-5x. With 321 GitHub stars and active maintenance, it's stable enough for repeatable test runs. Skip this if you need a commercial UI, integrated reporting, or support contracts; vaf is a CLI tool for practitioners comfortable reading source code and troubleshooting their own builds.
Bluetooth security researchers and red teams testing Broadcom chipsets should choose InternalBlue for direct firmware-level access that commercial tools simply don't provide; the 745 GitHub stars reflect active community validation of its attack primitives. This is genuinely free and requires no licensing friction, which matters when you're iterating on exploit chains. Skip this if you need GUI-driven penetration testing or support for non-Broadcom wireless stacks; InternalBlue is command-line research infrastructure, not a commercial pentest platform.
