Trail of Bits Pentest Pricing in 2026

Trail of Bits is a New York-based security research firm that operates at the highest tier of technical depth. Their engagements focus on cryptographic systems, smart contracts, compilers, and high-complexity targets that require custom tooling. This is not an entry-level vendor.

Trail of Bits does not publish pricing. Estimates below are triangulated from Astra, Deepstrike, and industry day-rate data for boutique security research firms ($4,000-$7,000/day senior boutique, BSG data). All engagements are scoped via direct contact.

Triangulated Pricing Estimates

Web / API audit
$30k-$60k

Full methodology, custom tooling, published reports

Is Trail of Bits Right for You?

Trail of Bits is the right choice if: (1) you are building cryptographic systems or protocols, (2) you need your findings published for community trust, (3) your target requires custom tooling and original research, (4) you are a blockchain/Web3 project requiring Slither, Echidna, or Medusa analysis. For standard web app pentests, Bishop Fox, NCC Group, or Cobalt will deliver similar results at lower cost.

Time-to-quote is 7-14 business days, one of the longer lead times in this market. Time-to-test after signature is typically 3-6 weeks due to researcher availability. If you need a pentest in 2 weeks, Trail of Bits is not the answer.
