hol-guard vs norviq
hol-guard: HOL Guard acts as an antivirus for AI harnesses, intercepting tool actions to protect against file changes and network contact. It also includes `plugin-scanner`, a complementary tool for linting and verifying AI plugins and packages in CI environments before release, ensuring quality and security.; norviq: Norviq is a policy enforcement point that intercepts and evaluates every LLM agent tool call against OPA/Rego policies on Kubernetes. It prevents potential risks like prompt injection or reasoning errors by ensuring tools only run if explicitly allowed by policy, enhancing AI safety and auditability.

TL;DR
hol-guardSecurity & Safety · ★ 969
When to choose:
- You run Codex, Claude Code, Copilot CLI, Cursor or similar and want a check before new or changed tools run.
- You maintain plugins, skills or MCP servers and want a CI step such as `plugin-scanner verify .`.
- You want local receipts of what was approved or blocked.
When to skip:
- You need a clear licence in GitHub's metadata today; our data shows none detected.
- You want a minimal tool: the README covers a large surface of commands and integrations.
- You cannot accept extra approval prompts in your agent workflow.
