CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Penetration testers who need to systematically test for Local File Inclusion flaws will find Burp-LFI-tests valuable because it consolidates proven LFI payloads and exploitation chains into a Burp extension, cutting manual payload crafting time during assessments. The tool is free and maintained on GitHub with solid community engagement, removing cost friction from your toolkit. This is not a replacement for manual testing or general vulnerability scanning; it's narrowly built for LFI-focused work, so teams expecting broad web vulnerability coverage or automated exploitation should look elsewhere.
Mid-market and enterprise teams securing Layer-1 protocols, smart contracts, or custom DeFi runtimes need FYEO Custom Fuzz Testing because it builds harnesses around your actual threat model instead of running generic fuzzing templates against your code. The stateful execution with shadow-state tracking and invariant checking catches logic flaws that stateless fuzzers miss, and CI integration means you're re-running those same reproducible seeds on every release. Skip this if your codebase is small or you're looking for a self-service tool; FYEO's 12-person team is built for hands-on engagement with mid-market and up, and that model doesn't scale to solo developers or teams that need instant turnaround.
