CISE is done by and for maritime surveillance stakeholders: EU/EEA Member States, their maritime surveillance authorities and European Agencies.
The European Commission coordinates the development of CISE. The Commission guarantees the interoperability standards, and encourages stakeholders to engage, share and contribute to CISE. Because CISE is voluntary, it relies on the commitment and participation of its stakeholders. In particular, military and civilian sectors have been called upon to strengthen communication and cooperate to exchange more maritime surveillance information.
The CISE Stakeholder Group coordinates the activities of the transitional phase of CISE. The members are experts designated by the EU/EEA member states and representatives from the European Commission, EDA, EEAS, EFCA, EMSA, Frontex and SatCen.
The Common Information Sharing Environment (CISE) is a voluntary collaborative EU initiative which aims to make European and EU/EEA member states surveillance systems in the maritime domain interoperable to give all concerned authorities from different sectors access to classified and unclassified information they need to conduct missions or monitor human activity at sea.
