How to choose
Match autonomy level to your environment: fully local agents like Nightcrawler suit air-gapped needs while cloud agents like Audn.AI target external AI surfaces. Check integration points—Harden plugs into coding agents, strix and AutoCVE work on source repos, and Shieldstral monitors fleets. Revenue models vary from $26k/mo enterprise tools to open-source upvote-driven projects; avoid agents lacking verification steps or clear scope boundaries. Common traps include over-reliance on synthetic-face detection alone or choosing high-upvote tools without testing their actual CVE false-positive rate.
