MIKE MULLEN | Chief Operating Officer

Mike keeps Pathfynder's train running and Artie well trained.

When Mike isn’t keeping the Pathfynder train on the tracks, he hacks around the golf course, reads voraciously and gets into trouble with his wife and two kids around Washington, DC.

BRYAN CLEMENTS | Senior Director, Cyber Operations

Bryan is Pathfynder's chief hacker and cyber collaborator.

Prior to Pathfynder, Bryan worked in the U.S. Intelligence Community supporting mission critical cyber operations. After nearly 20 years supporting the U.S Government, Bryan observed a growing gap between the capabilities of cyber adversaries and blue team defenders. In an effort to close that gap, Bryan transitioned to the private sector to conduct Red/Purple team assessments against organizations ranging from midsize to Fortune 100 focused on securing networks from attack and educating defenders. Bryan supported Fortune 100 organizations maturation of their Insider Threat capability through the development of cyber analytics and playbooks.

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.

STEVE ROVELSTAD | Senior Director, DFIR

Steve is Pathfynder's fixer and "in the weeds" incident response dude.

Steve joins the team with deep expertise in leading corporate breach investigations, digital forensics, incident response, malware analysis, threat intelligence collection, cyber security training, and team management. Prior to joining the private sector, he served in the United States Army's cyber and intelligence communities.

When Steve isn't diving deep to help companies mitigate damage from cyber security incidents, he adds to Pathfynder's deep bench of flannel and beard aficionados. While he has a passion for the mountains and outdoors, his heart remains connected to his original island home in Hawaii where he enjoys spending time with his family around the beaches and ocean waters off Maui.

BRAD PALM | Senior Advisor

Brad is Pathfynder's tech geek and delivery dude.

Before Pathfynder, Brad worked as a SecDevOps strategist and threat hunter for his boutique consulting firm, BruteForce.

Brad earned a Mechanical Engineering degree from the University of St. Thomas and holds a Master of Science in Computer Science from the Naval Postgraduate School and has certifications with numerous acronyms from various accreditation bodies.

When Brad isn't cooking things in the lab for Pathfynder, he is spending time free-ranging his kids in the Montana playgrounds. He can be found frequenting local skate parks, climbing uphill to find back-country powder stashes, visiting distant beach breaks, and coaxing his kids to follow him on epic adventures.
