GUARDIAN features a modular design that allows it to be fully integrated with existing infrastructure or other HALO products. The accordion style structure allows automatic operation in constrained waterways. The double wall barrier with diamond shaped segments forms an impassible vertical wall in the water and naturally dissipates energy from the environment and impacts. The gate can be operated automatically, power-assisted, or manually.

GUARDIAN is the only waterside defence and access solution available to have exceeded parameters of the US Navy’s performance specifications. Prior to achieving US Navy approval, the system was rigorously tested for four years by marine defence and military experts, during which time the barrier was proven to stop a three ton vessel travelling over 40 knots within three metres.turally dissipates energy from the environment and impacts. The gate can be operated automatically, power-assisted, or manually.

MIL-STD-810G Environmental engineering considerations and lab tests

United States Military Standard that emphasises tailoring an equipment's environmental design and test limits to the conditions that it will experience throughout its service life, and establishing chamber test methods that replicate the effects of environments on the equipment rather than imitating the environments themselves. The MIL-STD-810 test series are approved for use by all departments and agencies of the United States Department of Defence (DoD)

The GUARDIAN RDB can be fully integrated with existing third-party port security barrier systems or other HALO® port security solutions.
