HALO Maritime Defense Systems (HMDS) provides state-of-the-art, floating Security Barrier Systems to protect strategic maritime assets like ports, naval bases, nuclear power plants, oil and gas facilities and other critical infrastructure. The HALO™ barrier represents a new type of security barrier system employing advanced composite materials and designed to provide systems that are by-design effective, low maintenance and eco-friendly. HALO™ is not a line of demarcation but rather a formidable, stable deterrent that physically denies access to vital maritime assets. Perimeter security begins at the sea.
