An elite arsenal of people, processes and technologies at your command.

Transforming digital security

In 2008, J.J. Thompson founded Rook Security in Silicon Valley to provide advisory services that solved the challenges of tomorrow. Four years later, large global clients desired enhanced security operations center capabilities that went well beyond alert throwing. Clients wanted to co-source their security services catalogue, and they selected Rook Security to be the partner to deliver the future of security operations management capabilities. Today advisory, managed security services, and software as a service capabilties are fused together to provide scalable security solutions that are effective at repelling, detecting, and managing threats to resolution.


Meet clients where they are. Lead them to where they want to be.


Fundamentally change the way people protect and utilize their digital systems.
