The EU Council's Horizontal Working Party on Cyber Issues (attachés) is scheduled to meet on 29 June 2026 at 10:00 in the Justus Lipsius Building, Brussels, according to a notice of meeting and provisional agenda published by the Council. The meeting will be held in a 1+2 format.
The agenda includes the adoption of the meeting's agenda, followed by debriefs from the European External Action Service (EEAS) on the Cyber Ambassadors meeting and on the like-minded deterrence group meeting, the latter under RESTREINT UE/EU RESTRICTED classification. The meeting will also feature a formal handover to the incoming Irish Presidency, which will take over the rotating Council presidency from the current holder. Any other business (AOB) will be addressed at the end.
Delegations are required to register their presence via the delegates portal, where Council documents are available; room attendants will provide copies on request. The meeting focuses on debriefs from the EEAS on cyber diplomacy and deterrence, along with the procedural handover to the Irish Presidency.
No prior coverage of this specific meeting exists in the available record. The meeting is a routine gathering of attachés-level cyber officials to coordinate EU cyber policy and receive updates from the EEAS on international cyber engagements.
