At harbours within the European Union, the International Maritime Organization’s (IMO) International Ship and Port Facility Security (ISPS) Code must be adhered to.

The Port of Helsinki is also required to monitor its closed harbour areas. The purpose of the ISPS Code is to prevent access to the port or ship by materials or people deemed to pose a danger to passengers, crew, the port or the ship.

The Code requires access and area control; personal, vehicle and cargo inspections; cooperation between ships and the port facilities; cooperation with the authorities and additional measures when security levels are raised, as decided by the police.

The Port of Helsinki is constantly reviewing security matters with the authorities. The Finnish Transport and Communications Agency Traficom conducts safety assessments of threats and risks to ports at least every five years.
