What are
our services?


We have experience auditing virtually any type of platform and code base, working with both vendors, enterprises, and startups. Combining a variety of techniques, tools and rigorous methodology, we discover design flaws and implementation vulnerabilities that others have missed. We understand complex systems and have extensive expertise providing fine-tuned application security. We will find bugs, but we know that is just the first step in the process.

Reverse engineering is the art of extracting knowledge or design information from a built artifact. Understanding the nitty-gritty details of a proprietary network protocol, extrapolating vulnerability details from a binary patch, or reproducing obfuscated routines are just a few examples of the reverse engineering challenges successfully executed by our team. We enjoy solving those technical puzzles and we are well equipped to provide tailored services in this space.
