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.

Our clientele ­ -ranging from Facebook to DARPA- ­ lead their industries. Their dedicated security teams come to us for our foundational tools and deep expertise in reverse engineering, cryptography, virtualization, malware, and software exploits. According to their needs, we may audit their products or networks, consult on the modifications necessary for a secure deployment, or develop the features that close their security gaps.

We’re especially well suited for the technology, finance, and defense industries.

After solving the problem at hand, we continue to refine our work in service to the deeper issues. The knowledge we gain from each engagement and research project further hones our tools and processes, and extends our software engineers' abilities. We believe the most meaningful security gains hide at the intersection of human intellect and computational power.
