Trail of Bits

Since 2012, Trail of Bits has secured the software, blockchains, and cryptography that high-value targets run on. Our Software Assurance teams review systems across the whole SDLC: application code, cloud, and architecture; AI/ML systems from training data to deployed agents; every layer of a blockchain, from smart contracts to bridges; and cryptographic protocols, from zero-knowledge proofs to post-quantum migrations. Our Security Engineering team embeds with yours to build custom tooling and fix vulnerabilities from development through deployment. Our Research & Development group turns multi-year research into open-source tools, papers, and standards. Every engagement leaves something behind: human-validated findings, plus CI rules and fuzzers that catch the same bug class next time. We maintain Slither, Echidna, and Medusa, and 620 of our audits are public.
