Open Letter to Security Professionals

We have served this country in national security, law enforcement and military organizations. Each of us has decades of experience keeping our Homeland safe, here and abroad. Our experience spans the use of technology, intelligence, people, and assets to keep our country safe.

We have a combined 150 years’ experience, having served in leadership positions in the Central Intelligence Agency, Department of Homeland Security, Federal Bureau of Investigation, Department of Defense, New York Police Department, Office of National Intelligence, Transportation Security Administration, and United States Secret Service.

Today, we serve as advisors to Evolv Technology. We have known this company for years; many of us have worked with Evolv for nearly a decade. Our work has included reviewing the current business and products of Evolv, discussions with customers on their use of the technology, and discussing new product concepts. We know the company well, we know the people who run it, and regularly meet with Evolv and their customers.

We believe that Evolv and its management are dedicated to their mission to Make the World a Safer Place. They are committed to understanding the best use of their products, making improvements to the technology over time, and finding ways they can help their customers achieve their security objectives.

We have seen a wide variety of security technologies over our careers. The Evolv Express system provides an innovative approach to screening people, differentiating weapons from personal items as people walk through without always having to stop. We have seen the Evolv Express’ capabilities improve over time through both technological improvements and a deeper understanding of operational environments. Evolv combines the knowledge of security experts, experience operating thousands of systems screening millions of people, best in class engineers, committed workforce, continuous understanding of customers’ needs, and awareness of current threats to improve the technology and provide guidance on how it can best be used. The company cares deeply about ensuring customers and security professionals fully understand the system and they operate with high integrity in discussions about their technology and its capabilities.

Finally, we strongly believe that a security plan should include multiple layers to address different threat vectors and provide redundancy. These layers include people, process and technology working together. There is no single layer of security that will provide 100% security, that is why there are multiple layers which have proven to be the most successful in mitigating the highest degree of risk. Evolv’s solutions can be an important security technology to help detect and prevent threats from entering prohibited areas.
