Yanek Korff BS COO, Expel, Inc.

Yanek Korff BS

Yanek Korff has served in information technology or information security roles for nearly 20 years: from a student help desk technician in the musty basement of Swem Library at William & Mary to the VP of Managed Defense at Mandiant and CTO of FireEye as a Service at FireEye thereafter. Yanek is currently the COO at Expel, a DC-area information security startup, and is responsible for “filling all the spaces in between.”

Yanek joined Mandiant in 2010 to establish and grow a new managed services business line. In five years he grew the business into a global follow-the-sun managed threat detection and response service (Gartner now calls this an MDR) helping customers mitigate the consequences of security breaches associated with state-sponsored attackers. FireEye acquired Mandiant in December 2013 when the service represented over a third of Mandiant’s revenue. Branded “FireEye as a Service,” it became a major focus area for FireEye and grew beyond 100M in sales prior to his departure.

Prior to Mandiant, Yanek was responsible for the vast majority of AOL’s security infrastructure including authentication, authorization management, Public Key Infrastructure (PKI), systems that supported incident response and investigations, and a proprietary eDiscovery system addressing legal compliance needs. This included responsibility for both software development and security engineering work supporting AOL’s unique scope and scale.

Yanek graduated with a Computer Science degree from William & Mary, a Masters in the Management of Information Technology from the McIntire School of Commerce at the University of Virginia and was the principal author for Mastering FreeBSD and OpenBSD Security, published by O’Reilly.

Yanek lives with his family in Vienna, Virginia with three dogs, as many fish and corals as he can fit into a 300 gallon saltwater aquarium, and usually a caged rodent or two depending on the week. When he’s not fully engaged with Expel business, he’s likely doing what he’s told, or playing video games. Because he’s apparently still ten years old on the inside.
