As activity on the seabed continues to rise, it is more important than ever for stakeholders to come together to discuss innovative technologies and strategies for the protection of critical undersea infrastructure. Seabed Security (6-7 October 2026 in Troia, Portugal) will focus on the current threat context for undersea infrastructure, the development of new strategies for seabed activity, and the cutting-edge systems being employed for the defence of the seabed.
With themes spanning the full breadth of the undersea community, the conference provides a platform for engaging discussions that will ultimately contribute to increasing the security and resilience of critical undersea infrastructure at a time when stakeholders are seeking to define their approaches to this task. Join us at Seabed Security 2026 to meet with senior military, government, and industry representatives operating in the underwater space in order to secure critical undersea infrastructure against growing threats.
