Physical fences are only one component of a comprehensive border security system, and only one of several areas where Sandia is involved in border security work. Sandia’s security capabilities encompass the full spectrum of physical security, including intrusion detection, alarm assessment technologies, performance testing, technology evaluation, vulnerability assessment, design, development, installation, and training. Recently Sandia helped evaluate vehicle barrier performance of fence technologies for borders by conducting a series of successful crash tests to evaluate the design and perform of border fences. Sandia supports the Fence Lab initiative within SBInet, a technology network component of the Secure Border Initiative under DHS Customs and Border Protection.
