Greystone Protective Services

Maritime Support

Greystone roots are in maritime support. Greystone's management started in the U.S. Navy SEALs. They draw upon decades of real-world experience. During active duty military service, Greystone personnel played key roles in major organizational maritime and riverine development projects around the world, and starting new operations that provided maritime security to remote areas around the world. Greystone has taken this intrinsic knowledge and applied it to the commercial sector, enabling our customers to safely operate in austere maritime environments.


Greystone has provided services and training to the U.S. Navy, U.S. Coast Guard, International Maritime Special Operations Forces, U.S. Merchant Marine Academy and commercial companies. Our team includes trained U.S. Coast Guard / U.S. Maritime Administration certified Vessel and Company Security Officers and Port Facilities Security Officers and U.S. Navy Special Operations (SEAL).


Greystone furthers its assistance to our customers by providing boat acquisition, equipment, and follow-on support packages. Greystone personnel are specialists selected for their expertise in Riverine and Special Operations and tactics, Port Security, Search and Rescue, Maritime Law Enforcement, Navigation, Small Boat/Patrol Boat Operations, and other waterborne safety and security subjects.
