Built Different.

Viper Offensive Security is run by a hands-on offensive security engineer with over 15 years of practical attack experience — across embedded systems, Web3 protocols, enterprise networks, and AI systems.

We work with a small number of clients at a time — by design. Every engagement is led by a senior engineer, not handed off to a junior team. No account managers, no revolving door of analysts. When you hire Viper, you get the person who actually does the work.
