Our team is the foundation of our success.

Atredis Partners was created by a number of security industry veterans who wanted to prioritize offering quality and client needs over the pressure to grow rapidly at the expense of delivery and execution. A key part of that has been building one of the most recognized and highly-respected teams of security researchers and consultants in the world.

Based all over the United States and Canada, Atredis Partners team members have presented research over fifty times at the BlackHat Briefings conference in Europe, Japan, and the United States, as well as many other notable security conferences, including RSA, ShmooCon, DerbyCon, ReCon, BSides, and PacSec/CanSec. Most of our team hold one or more advanced degrees in Computer Science or engineering, as well as many other industry certifications and designations. Atredis team members have authored several books, including The Android Hacker’s Handbook, the iOS Hacker’s Handbook, Wicked Cool Shell Scripts, Gray Hat C#, and Black Hat Go.
