Common questions
- How many verified Incident response providers are there in United States?
- Trustgent lists 40 verified Incident response providers headquartered in United States. Every listing carries a cross-referenced (L2) verification level or higher, meaning independent third-party signals corroborate the capability claim. Ranking is plan-blind: verification level, contributing record count, and recency are the only signals used.
- What does “L2 verified” mean at Trustgent?
- L2 (cross-referenced) means Trustgent has independently corroborated the provider’s Incident response capability claim via at least three independent public sources, company registry, leadership team on LinkedIn or Crunchbase, and one or more capability attestations (case studies, published talks, open-source contributions, partner-program certifications). L3, L4, and L5 add client-authorized evidence and structured interviews on top.
- How is a provider’s rank determined on this page?
- Trustgent’s ranking function uses three signals only: verification level (L2 through L5), contributing record count, and most-recent verification date. Plan tier is never an input. A free-plan provider always outranks a paid-plan provider with weaker evidence. The rule is enforced by a hardcoded allowlist in the ranking code; see the Trustgent Attestation Protocol for the formal specification.
- How often is verification refreshed?
- Every verified record on Trustgent expires after 90 days unless re-attested. L5 (continuously monitored) providers agree to rolling audit and a live freshness gate. A provider’s tier drops automatically if the cadence lapses. The last-verified date appears on every listing so buyers can see exactly how fresh a claim is.
- How do I evaluate an AI implementation partner beyond the demo?
- Trustgent’s methodology at /how-we-verify sets out a six-level scale (L0 through L5) buyers can use directly. Ask for evidence at the level you need: for L3+ ask for client-authorized case-study documentation; for L4+ ask for structured client-reference interview notes.
