Modular Design with Multiple Configurations

The Defender system is manufactured from plastic, composite and stainless steel materials, reducing maintenance needs and ensuring a long service life. The barrier can support a fiber or stainless steel net capture system, eliminating threats from nuisance watercraft (jet skis) to state sponsored attack vessels. Lights, radar reflectors, and signage can be mounted using industry-wide, standard hardware. Defender can be fully integrated with existing third-party port security systems or other HALO waterside security barriers.

All of our HALO products are:

  • Capable of integrating oil abatement/containment systems.
  • Able to support third-party sensors (safety, security and environmental).
  • Marine mammal and environmentally friendly.
