Services
We fix the software behind the bug.
Since 2012, Trail of Bits has secured the software, blockchains, and cryptography that high-value targets run on.
We pair deep security research with an attacker's mindset, then hand your engineers the tooling to keep the bugs from coming back.
What we do
-
Software Assurance
Multi-disciplinary security reviews across the whole SDLC, with a team sized to your threat model rather than a fixed template.
-
Under Software Assurance
-
AI/ML Security
We review AI systems end to end, from training data and MLOps pipelines to model artifacts, inference hardware, and deployed agent loops.
-
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.
Office hours
Book a technical office hours session
Spend a free hour with one of our engineers on a specific technical problem: an architecture you're unsure about, a tool you want to stand up, a finding you can't reproduce. No pitch and no sales engineer, just a working session with someone who does this every day. Bring code if you have it.
