Bryan Clements
Senior Director, Cyber Operations
Bryan has over 20 years of experience performing technical offensive services. After nearly 17 years executing Red Team engagements for the U.S. Intelligence Community, Bryan observed a growing gap between the capabilities of cyber adversaries and the security teams responsible for stopping them. In an effort to close that gap, Bryan transitioned to the private sector where he conducts Red/Purple team assessments focused on securing networks and educating defenders for organizations ranging from midsize to Fortune 50. Bryan also helps organizations maturate their Insider Threat capabilities through the development of cyber analytics and playbooks, and has operated in a variety of industries including energy, financial services, technology, e-commerce, healthcare, crypto, and manufacturing.
When Bryan isn’t performing Red/Purple teams or hunting insider threats, he is an avid Philadelphia Eagles fan who never misses a game. When he isn’t researching new tools or techniques, he can often be found around the softball field or hiking the mountains of Colorado.
