The acquisition of Lennon Security Corporation’s Technical Surveillance Countermeasures (TSCM) Services and Assets expands our security and device expertise.

Washington, D.C. (October 16, 2019) – AT-RISK International, Inc. (AT-RISK), a leader in proactive threat analysis, intelligence, protection, investigations, consulting and security training services, announced today the acquisition of Lennon Security Corporation (Lennon Security) and their proprietary Technical Surveillance Countermeasures (TSCM) Services and Assets. Additionally, AT-RISK employees are enhancing their training in the area of TSCM methodology, which determines the existence of actual audio and video devices (detection of telephone/fax/computer taps and bugs), along with the vulnerability of electronic eavesdropping.

Lennon Security is a veteran-owned security-consulting firm headquartered in the Washington, D.C. metropolitan area. Patrick J. Lennon created the firm in 1988 with the goal of providing security services with those standards and methods utilized by the United States Secret Service (the Secret Service).

“Working with Pat for the past two decades has truly enhanced my depth of understanding and the criticality of technical surveillance countermeasures and the value Pat brings to protective operations. I am excited to have him join our team and mentor professionals as we expand our protective operations to include this often-overlooked aspect of risk management,” said Chuck Tobin President and CEO of AT-RISK.

”It is my honor to be working with AT-RISK providing technical surveillance countermeasures and feel that AT-RISK is the right company to carry-on the same professional excellence that Lennon Security’s clients have come to experience over 20 years,” said Patrick Lennon, President of Lennon Security.

Mr. Lennon, founder and president of Lennon Security, brings 46 years of in-depth security experience to AT-RISK. He has served more than 21 years with the Secret Service as a security specialist where he planned, developed and implemented many comprehensive security programs for the President and Vice President of the United States and for foreign dignitaries. After retiring from the Secret Service, he served six years as Director of Technical Security for Vance International, Inc., a large security consulting firm in the Washington, D.C. area, where he developed their countermeasures program and was responsible for providing services such as technical surveillance countermeasures sweeps (detection of bugs and telephone/fax/computer taps), threat/risk and vulnerability assessments and executive risk analyses for Fortune 500 companies. 

Lennon Security’s staff of consulting professionals brings extensive experience in the Secret Service, military, law enforcement and intelligence arena, and provides the necessary expertise and experience required to successfully monitor and conduct technical surveillance countermeasures.
