Best for
  • Security auditors
  • DevOps engineers
  • Site owners needing DNS/email security assessments
  • Compliance teams
  • Engineering teams scaling AI coding agents while controlling spend
  • Platform teams that need auditable, rollback-aware agent execution records
  • Organizations using multiple agents (Claude, Codex, Gemini) under one governed flow
Not for
  • Unauthorized domain reconnaissance
  • Users needing non-DNS features
  • Scenarios requiring local deployment without Cloudflare support
  • Developers who just want a simple code-completion helper without run governance
  • Teams unwilling to accept local JSONL run records with HMAC signing
  • Environments without a supported adapter (Claude/Codex/Gemini CLIs, direct provider, or verifier-only)
Required permissions
  • Queries public DNS via Cloudflare DoH
  • Accesses CT logs and RDAP data
  • Some tools require a paid API key
  • No authorization required from the target domain
  • Read/write access to the configured repo root (writable scope restrictable via --allow-path/--deny-path)
  • Ability to invoke the chosen agent CLI (Claude/Codex/Gemini, etc.) and its underlying model account
  • Local disk writes for run records, receipts, and share outputs (share/run-receipt., etc.)
  • Execution of user-configured verifier commands (e.g. npm test)
Risks and side effects
  • Scan results may reveal sensitive information and should only be used for authorized testing
  • Misuse for unauthorized reconnaissance may violate laws
  • Free tier has limited quota; advanced features require payment
  • Data handling is subject to BlackVeil's privacy policy
  • Verifier commands are executed; poorly chosen verifier commands carry security risk despite preflight policy checks
  • Cost and token figures may be estimates (labeled with provenance) and should not be treated as settled accounting
  • Receipt integrity must be verified before use as trustworthy evidence; missing rollback evidence is flagged as EVIDENCE_BOUNDARY
  • Policy defaults come from martin.config.yaml and can be overridden by CLI flags; misconfiguration can loosen safety boundaries
