Last Updated: January 8, 2026
Private maritime security contractors (PMSCs) are specialized firms that protect vessels from piracy, terrorism, and maritime crime. In 2026, these contractors have become essential for safe passage through increasingly dangerous waters, with over 88 Houthi attacks on commercial vessels since November 2023 and a resurgence of Somali piracy. This guide covers everything shipping companies need to know about hiring, licensing, and working with maritime security contractors in today’s threat environment.
What Is a Private Maritime Security Contractor?
A private maritime security contractor provides armed and unarmed security personnel to protect ships, crews, and cargo during high-risk transits. Unlike traditional security guards, these professionals operate in international waters and conflict zones, requiring specialized training in maritime law, rules of engagement, and vessel defense tactics.
The modern PMSC industry emerged in the late 2000s during the Somali piracy crisis, when attacks in the Gulf of Aden disrupted global shipping routes. Today, the maritime security services market has grown to $26.77 billion in 2026, reflecting escalating threats in the Red Sea, Gulf of Guinea, and Indian Ocean. Contemporary maritime security contractors deploy teams of 3-4 armed personnel for typical transits, with larger vessels sometimes requiring 6-8 guards depending on threat levels.
Evolution of Maritime Security Services
Maritime security has transformed from basic watchkeeping to sophisticated operations integrating AI threat detection, satellite surveillance, and real-time intelligence sharing. The International Chamber of Shipping’s new BMP Maritime Security Guidelines (March 2026) consolidate all regional guidance into a single 60-page framework that PMSCs must now follow. This evolution reflects increasingly complex threats, including anti-ship missiles, drone attacks, and cyber warfare that traditional naval forces alone cannot counter.
Legal Framework & Licensing Requirements
Navigating the legal landscape is critical when hiring maritime security contractors. Regulations vary by flag state, operating region, and whether teams are armed.
International Maritime Laws Governing PMSCs
Private maritime security companies operate under a patchwork of international conventions:
- UNCLOS (United Nations Convention on the Law of the Sea) establishes the legal framework for self-defense in international waters
- ISPS Code (International Ship and Port Facility Security Code) mandates security plans and risk assessments
- SOLAS Convention Chapter XI-2 requires ships to maintain security protocols
- IMO Resolution MSC.1/Circ.1443 provides interim guidance for PMSCs using armed guards
ISO 28007 Certification: The Gold Standard
ISO 28007:2015 is the definitive certification for private maritime security companies, building on ISO 28000 security management systems. The standard requires PMSCs to demonstrate:
- Financial stability and insurance coverage
- Documented operational procedures
- Crew training and competence standards
- Weapons handling and use-of-force protocols
- Incident reporting and investigation processes
Certification involves third-party audits by accredited bodies like Lloyd’s Register Quality Assurance. For shipping companies, verifying ISO 28007 accreditation is the first step in contractor selection.
Flag State Licensing Requirements
- United Kingdom: The UK Department for Transport requires PMSCs to hold a Private Security Company license under ISO 28007 standards. The process includes background checks, financial vetting, and proof of maritime security experience.
- United States: No federal PMSC licensing exists, but contractors must comply with State Department ITAR regulations for weapons export and Coast Guard MARSEC Directive 104-6 for high-risk waters operations.
- Liberia Registry: Requires PMSCs to show compliance with MSC.1/Circ.1443 and ISO 28007 certification, or equivalent national accreditation.

Core Services & Service Types
Modern maritime security contractors offer tiered service packages based on vessel type, cargo, and risk level.
Armed vs. Unarmed Vessel Protection Teams
Armed Security Teams: Deploy military veterans with combat experience, carrying rifles and sidearms. Required for high-risk areas like the Red Sea and the Gulf of Guinea. Teams conduct:
- 24/7 watchkeeping with night vision equipment
- Embarked security from port to port
- Vessel hardening supervision
- Crisis response and repel boarders drills
Unarmed Security Advisors: Provide risk assessment, crew training, and security planning without weapons. Suitable for lower-risk transits and insurance compliance.
Anti-Piracy Operations & Vessel Hardening
Maritime security contractors implement multi-layered defenses:
- Physical Barriers: Razor wire, anti-climb fencing, reinforced bridge protection
- Citadel Construction: Safe rooms with independent communications and supplies
- Water Cannons & Foam: Non-lethal deterrent systems
- Drone Detection: Radar and acoustic sensors for UAV threats
- Crew Training: Security drills, threat recognition, and emergency protocols
Risk Assessment & Threat Analysis
Before any transit, PMSCs conduct comprehensive risk assessments, analyzing:
- Historical attack data and current intelligence
- Vessel speed and freeboard height
- Crew nationality and experience
- Cargo value and type
- Route timing and weather conditions
The 2026 BMP Guidelines emphasize dynamic threat assessment, requiring updates every 3-6 months based on the Maritime Industry Security Threat Overview (MISTO).
High-Risk Area Operations: Threat Updates
Red Sea & Gulf of Aden: Houthi Attack Zone
Since November 2023, Houthi forces have launched at least 88 attacks on commercial vessels using anti-ship missiles, drones, and explosive boats. The U.S. Maritime Advisory 2024-008 warns that ships transiting the southern Red Sea face the highest risk from terrorism and hostile actions.
BMP Recommendations:
- Maintain a minimum of 100 nautical miles from Yemen’s coastline
- Turn off AIS transponders unless safety-compromised
- Provide hourly position reports to NAVCENT NCAGS
- Embark armed security teams for all transits
- Implement strict VHF communication protocols
Gulf of Guinea: Persistent Piracy Threat
Despite reduced media attention, the Gulf of Guinea remains dangerous. Nigerian pirates operate up to 200 nautical miles offshore, targeting tankers and cargo vessels for cargo theft and crew kidnapping. PMSC teams report a 100% success rate in deterring attacks when proper vessel hardening and armed guards are deployed.
Somali Basin: Resurgence Warning
After years of calm, Somali pirates have successfully hijacked three merchant ships since November 2023, with attacks occurring hundreds of miles offshore. The 2026 BMP Guidelines reinstated Somalia as a high-risk area, recommending convoy operations and embarked security.
Best Management Practices (BMP) Compliance
The new BMP Maritime Security Guidelines consolidate all regional advice into one document, replacing BMP 5 for Middle Eastern waters. Key changes include:
- Integrated cyber security measures
- Drone and loitering munition threats
- Enhanced bridge protection standards
- Updated reporting procedures via the joint industry website maritimeglobalsecurity.org
