What Guardian Audits does
Guardian Audits (legal entity: Guardian Enterprises LLC) is a smart contract security service provider founded in 2022 and headquartered in New York. The firm delivers deep manual security audits, agentic automated audits, invariant fuzzing, operational security assessments, and technical risk/compliance documentation to blockchain protocols. Its flagship methodology deploys two competing internal audit teams to maximize independent vulnerability discovery, supplemented by reusable invariant fuzzing harnesses and a Pay-Per-Vulnerability pricing option. The customer base spans DeFi protocols (GMX, Synthetix, USDT0, Ethena, Jupiter, Orderly, Dolomite, Umami, Poolshark, MIMSwap), blockchain infrastructure (LayerZero, Arbitrum), NFT projects (Yuga Labs, Azuki), and adjacent entrants including PayPal. Across 150+ engagements the firm reports securing over $44.99 billion in digital assets and identifying 300+ critical vulnerabilities, with 13 global security competition wins attributed to the research staff.
The product surface includes the core Audits & Pentests engagement, the 2025-launched Guardian Sentry automated audit platform (Helix-agent driven, findings within 30 minutes and full reports within 48 hours), Monitoring & Defense for live production threat detection, OpSec for key management and infrastructure exposure, and Risk & Compliance for institutional-grade technical diligence. The go-to-market combines a sales-led enterprise motion (intake forms, kickoff calls, quote-based scoping) with a freemium self-serve Sentry funnel and a client referral network anchored by GMX and Cyfrin. Business model mechanics mix one-time audit fees, recurring post-launch retainers (e.g., GMX), and a freemium PLG entry tier designed to convert teams into paid engagements.
