Trail of Bits Services

Software Assurance Multi-disciplinary security reviews across the whole SDLC, with a team sized to your threat model rather than a fixed template.

Application Security Deep code, cloud, and architecture review that finds the root cause and the fix that retires the whole bug class.
Blockchain We review every layer of a blockchain system, from smart contracts to nodes and bridges, backed by Slither, Echidna, and Medusa.
Cryptography PhD-level cryptographers who build and break real protocols, from zero-knowledge proofs and MPC to post-quantum migrations.

Security Engineering An embedded team that builds custom security tooling and remediates vulnerabilities across your pipeline, from development through deployment. Research & Development Multi-year research that uncovers Internet-scale vulnerabilities and turns the findings into open-source tools, papers, and standards. Everything we do View all services
