In Security & Guardrails

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade A reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Is HOL Guard safe?

Public supply-chain signals for HOL Guard are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but HOL Guard carries less obvious unverified-evidence risk than projects with thin signals.

Does HOL Guard publish package provenance?

Yes. HOL Guard's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does HOL Guard have an OpenSSF Scorecard?

HOL Guard has an OpenSSF Scorecard score of 7.6/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is HOL Guard actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does HOL Guard use?

HOL Guard ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are HOL Guard's commits signed?

95% of the last 100 commits to HOL Guard are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
