At sea, there are no walls or physical barriers. Everyone can sail everywhere, one of the maritime arena's greatest advantages, and the most challenging security aspect.

HALO Maritime Defense Systems (HMDS) offers unique maritime sea barrier solutions to secure critical assets vulnerable to water-based attacks. In a security-conscious world, both government assets – Navy Bases, Naval Ships in Hostile Territories, Airports, Coast Guard ships and facilities– and commercial and private assets such as ports, LNG Terminals, LNG Tankers, Nuclear Facilities, Oil Rigs, Desalination Plants, Pipelines, Palaces, and Cruise Ships– have a real, immediate, and critical need for high levels of protection. Protection levels that may be currently unfilled.


PROTECT critical assets on the waterside.

DETER opponents from attacking by a significant physical and visual barrier.

STOP attacks by an innovative design that transfers the impact's kinetic energy to the water, resulting in dramatic stopping power.

The HALO barrier system is specifically designed as a complete Sea Barrier Defense System. Its composites are designed to survive in harsh marine environments with zero disruption to the local ecosystem.  Its impact displacing and self-righting design not only allows it to handle high impact incidents but to do so while remaining intact and ready for secondary impact.

The modular, stable design of the HALO® structure in any sea state allows HALO to address specific security concerns while being part of an integrated security solution. HALO Maritime Defense Systems offers complete security payload packages including"

  • Remote monitoring to transmit live images to remote locations.
  • Anti-swimmer, or anti-diver drop-netting to prevent attacks.
  • Sub-surface sonar
  • Integration with third-party security solutions including lighting systems, sensors, and audible deterrents.

The complete maritime security solution is not complete without a robust access control system. HALO offers a fully automated marine gate system. The patented HALO Guardian and HALO Orion gate systems can span breakwater-to-breakwater, buoy-to-buoy, or into new and existing HALO Sentry barrier systems. The proprietary Guardian and Orion systems offer for the first time full or partial opening access to marine assets with the push of a button. No boat assists, no man-in-the-loop, no connecting or disconnect gates in the water.

HALO® marine security solutions are the Only  sea barriers on the market today rigorously tested by the US NAVY and the results INDEPENDENTLY verified.
