Maritime AIS Spoofing Protection and Vessel Surveillance Services

Protect Your Fleet From AIS Spoofing, GPS Jamming and Surveillance Attacks

Automatic Identification System (AIS) spoofing, GNSS jamming and GPS meaconing are no longer theoretical threats. Adversaries now routinely inject false vessel tracks to hide illicit cargo movements, redirect fleets into unsafe waters, manipulate vessel positions during insurance disputes and conduct economic warfare. Codesecure Solutions delivers the specialist maritime cybersecurity assessments and continuous monitoring services ship owners, charterers, flag states and port authorities need to detect these attacks and respond before they turn into incidents.

Our Chennai-based maritime security team combines deep experience in shipboard OT, ECDIS integrity checks, radar and AIS equipment from Furuno, JRC, SAAB, Kongsberg and other vendors, and purpose-built anomaly detection that flags spoofed tracks in near real time. Every engagement is aligned with IMO MSC.428(98), BIMCO cyber guidelines, IALA AIS recommendations and ISO 27001 so flag state and class inspections pass without friction.

Maritime AIS Spoofing and Surveillance Protection Services We Deliver

Codesecure's AIS spoofing and maritime surveillance protection portfolio covers prevention, detection and response:

AIS and GNSS Threat Assessment: On-board assessment of AIS Class A and B transponders, GNSS receivers, ECDIS and radar with focus on integrity of position data, cross-validation mechanisms and fallback sensors.
ECDIS and Bridge Systems Hardening: Security review of ECDIS, radar integration, sensor voting logic and backup positioning, including software patching status and vendor remote access controls.
AIS Spoofing Detection Service: Continuous monitoring service that cross-validates reported AIS tracks against radar, GNSS, inertial navigation and historical voyage patterns to flag spoofed or jumping vessel positions in near real time.
GNSS Jamming and Meaconing Protection: Engineering review of antenna placement, alternative PNT sources, redundant GNSS receivers and crew procedures for jamming events.
Incident Response for Spoofing Events: Dedicated maritime incident response playbooks for spoofing, jamming and false distress scenarios, including coordination with flag states, insurers and P&I clubs.
Fleet-Wide Surveillance Security Review: Cross-fleet posture assessment and uplift program for ship owners and managers operating 10+ vessels.

Our AIS Spoofing Protection Methodology

Codesecure follows a 5-phase methodology built specifically for vessel and fleet operators, respecting both the realities of a live bridge and the constraints of class surveys.

Phase 1: Onboard Discovery

Full inventory of AIS, GNSS, ECDIS, radar, gyro, inertial and VDR systems on each vessel in scope, plus shore-side vessel tracking platforms and fleet operations centers.

Phase 2: Threat Modeling

Tailored threat models for AIS spoofing, GNSS jamming and meaconing, false distress injection, historical replay and targeted mis-routing attacks against your specific trade routes.

Phase 3: Controls Implementation

Hardening of bridge systems, enabling cross-sensor validation, tightening vendor remote access, updating crew procedures and deploying anomaly detection agents.

Phase 4: Spoofing Simulation and Validation

Controlled exercises using safe spoofed tracks and GNSS simulators to validate detection, crew response and fallback procedures without risking real operations.

Phase 5: Continuous Monitoring

Ongoing SOC monitoring of AIS, GNSS and radar telemetry with near real time alerts for spoofing events, integrated with your fleet operations center and flag state reporting workflows.

Frequently Asked Questions

The best AIS spoofing protection is layered: enable cross-sensor validation on your bridge so AIS tracks are continuously checked against radar, GNSS, inertial and gyro data, upgrade to IALA-compliant authenticated AIS where available, harden vendor remote access on your ECDIS and radar systems, train crew on spoofing recognition procedures, and subscribe to a continuous monitoring service that flags spoofed tracks in near real time. Codesecure delivers all five as a single fixed-price package for ship owners and fleet managers.

AIS spoofing is performed by transmitting false AIS messages that look legitimate to other vessels, port authorities and online tracking platforms. Attackers include organized criminal networks hiding illicit cargo, state actors conducting influence operations, insurance fraud operators manipulating voyage data, and opportunistic attackers testing free spoofing tools. The attack vector is cheap and the defensive measures require both technology changes and crew training.

Yes. Codesecure's continuous monitoring service ingests GNSS, inertial, radar and AIS telemetry from your vessels and detects jamming patterns such as sudden position jumps, loss of satellite lock across all channels, degraded signal quality and inconsistent sensor readings. Alerts are sent to your fleet operations center within seconds and the system automatically correlates with published jamming hotspots in the Black Sea, Persian Gulf, Red Sea and other affected waters.

Our deliverables are built to the templates that DNV, ABS, Bureau Veritas, Lloyd's Register and Indian Register of Shipping inspectors are familiar with. Assessments map to IMO MSC.428(98), BIMCO cyber guidelines and IALA AIS recommendations. We have supported multiple flag state inspections and class surveys where our reports were accepted as evidence of cyber risk management under the ship safety management system.

A one-time AIS, GNSS and bridge security assessment typically costs INR 4 to 8 lakh per vessel depending on vessel type, size and the complexity of bridge electronics. Fleet-wide programs attract volume pricing. Continuous AIS spoofing monitoring is a separate subscription starting at a fixed per-vessel per-month rate. Codesecure offers a single fixed-price per-vessel package that bundles both.
