HALO Maritime Defense Systems patented maritime security products offer unique solutions to difficult marine security scenarios.

Tried and Tested

In United States Navy tests, the HALO SENTINEL Static Defensive Barrier and GUARDIAN Retractable Defensive Barrier system successfully stopped the United States Navy fast attack boat specification. We are proud that our system has been extensively tested and analyzed in a variety of scenarios and environmental conditions by the United States Navy and the results have been independently verified.

United States Navy crash testing demonstrated the amazing stopping power of the Sentinel and Guardian defensive barriers against a fast threat boat. Meeting the 99th percentile threshold for design basis watercraft as listed in the United States Navy Performance Specifications for the Anti-Terrorism, Force Protection - Boat Barriers (NAVY ATFP PRF BB 20090830)
