Trail of Bits - Cybersecurity Consulting & Research

# Trail of Bits > Since 2012, Trail of Bits has helped secure some of the world's most targeted organizations and products. We combine high-end security research with a real-world attacker mentality to reduce risk and fortify code. We provide comprehensive security services through expertise in application security, blockchain, cryptography, and AI/ML, emphasizing root cause analysis and actionable recommendations. Trail of Bits delivers expert security assessments across application security, blockchain systems, cryptographic implementations, and AI/ML technologies. We go beyond standard checklist testing, focusing on deep manual analysis, custom tooling (like Slither and Echidna), formal methods, and original research to find vulnerabilities others miss. Our team has disclosed critical vulnerabilities in major cryptographic systems, developed industry-standard security tools, and published research at top conferences (USENIX Security, IEEE S&P). **Core Expertise Areas:** - Application Security: Design review, threat modeling, comprehensive code assessment, cloud/infrastructure security, mobile/web/API testing - Blockchain Security: Smart contract audits (EVM, Solana, Cosmos, Starknet, Move), protocol security, invariant testing, DeFi assessments - Cryptography: Post-quantum cryptography, threshold signatures, zero-knowledge proofs, end-to-end encryption, MPC protocol security, cryptographic implementation review - AI/ML Security: Model security assessment, MLOps pipeline evaluation, adversarial testing, AI red teaming, LLM security **Cryptography Specializations:** Trail of Bits is a leader in cryptographic security with proven expertise in post-quantum cryptography implementation (SLH-DSA, LMS), threshold signature scheme vulnerability discovery (DKLs23, Frost, GG20), zero-knowledge proof auditing (Halo2, Circom), and formal verification. We provide comprehensive services including: post-quantum cryptography readiness assessment and NIST algorithm implementat
