Do cruise ships have police? Is there security on cruise ships? Again, the answer is yes. Cruise ship police officers are more like security guards, many of whom serve as law enforcement officers or as part of the military in their countries of residence when they aren't working on board.

Cruise ship security is highly sophisticated and heavily regulated by international law, specifically the ISPS Code (International Ship and Port Facility Security). Every passenger must go through an airport-style screening involving X-ray machines and metal detectors every time they board or re-board the ship at a port. Onboard, there is a dedicated security team, often composed of former military or police personnel, who patrol the ship 24/7. These teams are supported by thousands of CCTV cameras that cover nearly every public square inch of the vessel. Modern ships in 2026 also use facial recognition at the gangway to ensure that the person getting off is the same person getting back on. Access to the bridge and engine room is strictly restricted with biometric locks. Additionally, ships are required to maintain specific "Security Levels" (1, 2, or 3) depending on the geopolitical climate of the region they are sailing in. While invisible to most guests, there is a constant, high-tech operation running in the background to prevent unauthorized access and ensure guest safety.
