About Security & Guardrails
HVTracker independently evaluates 26 security & guardrails using daily signals from GitHub, package registries, and security databases. The category is open-source-first, with a limited set of public GitHub-hosted proprietary or source-available comparators when they are important ecosystem reference points. Each agent is scored on activity, adoption, transparency, safety, and identity. The top-ranked security & guardrail is HOL Guard with a trust score of 91.7/100 (Grade A). Other leading projects include REA and AiSOC.
