Alexandria, VA

Mandiant, the leader in advanced threat detection and response solutions, today announced the addition of Grady Summers to the executive team as vice president, customer success. Summers will be based out of the company’s Alexandria, Virginia office where he will work closely with Mandiant’s customers to improve their incident detection and response strategies and ensure they get the most out of their relationships with Mandiant. In addition, he will be responsible for developing and managing strategic relationships with Mandiant’s consulting partners.

“As a former CISO in a Fortune 100 company, Grady understands first-hand the challenges our customers face and is uniquely qualified to help them maximize their investment in Mandiant’s solutions,” said Mandiant President and Chief Operating Officer Travis Reese. “His addition to the team underscores Mandiant’s commitment to our customers’ success.”

Summers joins Mandiant from Ernst & Young LLP where he led the information security program management service line. Prior to that, Summers served as the chief information security officer (CISO) at General Electric (NYSE: GE) where he led GE’s global information security program including IT risk management, incident response, identity and access management, security policy and centralized security operations. As GE CISO, Summers also oversaw the development of GE’s first computer incident response team and was a leader of GE’s executive councils for information security, information governance and IT risk.

“The rise of cyber espionage and advanced targeted attacks is placing increased demands on security organizations to better protect their intellectual property and financial assets,” said Summers. “When attacks bypass preventive defenses, security teams need to be the first to know so they can be the first to act. Detecting, responding and containing these threats is something organizations must do on a daily basis. I look forward to helping them meet that challenge.”

Summers holds a master of business administration degree from Columbia University and a bachelor of science in computer systems and political science degree from Grove City College in Pennsylvania.
