What does MARSEC Level 1 indicate?

MARSEC Level 1 indicates "Normal operations." This level serves as the baseline security level for maritime operations, where the threat environment is considered stable, and no specific threats have been identified. Under MARSEC Level 1, vessels and port facilities are expected to maintain regular security measures and follow their established security plans.

This level signifies that while vigilance is always necessary, there is no heightened security posture required since there are no immediate or extraordinary threats. Vessels operate as usual, and standard precautions are sufficient to protect against potential risks without the need for additional security measures or resources.

Understanding this distinction is crucial for vessels and port facilities to ensure they remain ready to scale up their security measures if there is a change in threat perception, as seen in the other MARSEC levels.
