1stProtect.ai vs VxSig: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
1stProtect.ai is a commercial detection engineering tool by 1stProtect.ai. VxSig is a free detection engineering tool. Compare features, ratings, integrations, and community reviews side by side to find the best detection engineering fit for your security stack.
CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Threat analysts and incident responders who need to rapidly operationalize detections from malware samples should use VxSig; it's the only free tool that automatically generates Yara and ClamAV signatures from binaries, cutting the manual reverse-engineering work that normally takes hours per sample. Google's backing and 288 GitHub stars reflect active maintenance in a category where most competitors charge five figures annually. Skip this if your team lacks malware analysis experience or needs signatures for detection engines beyond Yara and ClamAV; VxSig assumes you know what you're looking for and can judge output quality yourself.
