Overview
Trail of Bits is a specialized cybersecurity consultancy and research organization that combines academic-grade technical depth with pragmatic, attacker-oriented thinking. Since its founding in 2012, the firm has partnered with highly targeted organizations to harden software, infrastructure, and cryptographic systems. Trail of Bits focuses on uncovering hard-to-find vulnerabilities, developing concrete mitigations, and equipping engineering teams with the tools and knowledge to prevent regressions.
Core Capabilities
-
Software Assurance: Comprehensive assessments that evaluate the security posture of system software, applications, and deployment environments. These engagements typically include architecture review, threat modeling, code and binary analysis, and prioritized remediation roadmaps.
-
Security Engineering: Custom tool development and hands-on remediation assistance to integrate security into development workflows, testing pipelines, and continuous deployment. The engineering team helps operationalize fixes and build automated defenses.
-
Research & Development: Independent, high-impact security research that advances the state of knowledge in vulnerability discovery, program analysis, and secure system design. Trail of Bits publishes findings and develops methods that the security community can adopt.
-
Expert Training Courses: Practical, instructor-led training covering reverse engineering, program analysis, penetration testing, language security, infrastructure security, and threat modeling to upskill internal teams.
-
Products and Continuous Assurance: Commercial and open products such as iVerify (mobile device security) and Crytic (smart contract analysis/continuous assurance) that help organizations maintain ongoing security hygiene and device/account protection.
Key Features
-
Deep technical analysis: Trail of Bits combines manual and automated analysis techniques—binary reverse engineering, static analysis, and dynamic testing—to find subtle, high-severity flaws often missed by conventional scans.
-
Attacker mindset: Engagements are guided by a real-world adversary perspective, prioritizing findings by exploitability and business impact to ensure remediation effort yields measurable risk reduction.
-
Custom tooling & automation: The team builds bespoke tools and integrates security automation into CI/CD pipelines to detect regressions and scale testing across complex codebases.
-
Research-driven discoveries: The company conducts and publishes advanced security research, contributing novel techniques and public advisories that benefit the broader ecosystem.
-
Practical remediation and mentorship: Beyond identifying bugs, Trail of Bits helps implement effective fixes, documents best practices, and trains engineering teams to sustain security improvements.
