Our team members have responded to incidents including the 2015 Ukraine power grid attack, analyzed the CRASHOVERRIDE malware identified in the 2016 Ukraine electric grid attack, analyzed the TRISIS malware discovered in the petrochemical facility attack in 2017, built and led the National Security Agency (NSA) mission to identify nation-states targeting critical infrastructure, and performed assessments on hundreds of assets around the world. The Dragos Professional Services team serves as the boots-on-the-ground industry experts in solving industrial control system (ICS) security challenges. We then bring current operational insights back from the field and integrate them into our software technology: The Dragos Platform. We're looking for individuals who are passionate about safeguarding civilization, with hands-on experience in performing vulnerability assessments, penetration tests, and red teaming.

  • Create and facilitate tabletop exercises tailored to customer infrastructures and environments, with detailed scenarios illustrating consequences and effects. Participate in exercises in order to showcase Dragos capabilities and transfer knowledge that enables customers to respond to real-world attacks.
