UK and Poland deepen cyber and defence cooperation under new treaty
Shared initiatives under the treaty include maritime security, digital technologies, energy resilience and measures targeting irregular migration and hostile state activity.
The United Kingdom and Poland have agreed a broad package of defence, cybersecurity and security initiatives under a new Security and Defence Partnership Treaty. The agreement strengthens cooperation on defence, sanctions, border security, technology and energy resilience.
Defence cooperation is a central element of the treaty, with both countries planning joint work on missile systems, expanded ammunition production and closer defence-industrial cooperation.
Large-scale military exercises focused on counter-drone operations, electronic warfare and missile defence are also expected to strengthen interoperability between British and Polish forces on NATO’s eastern flank.
Cybersecurity and hybrid threat response feature heavily in the agreement. Britain and Poland plan to coordinate cybersecurity efforts, sanctions enforcement and responses to foreign information manipulation and interference.
A new counter-hybrid working group will support efforts to disrupt hostile state activity, while dedicated cooperation on disinformation aims to strengthen democratic resilience and expose coordinated influence campaigns.
Additional projects include cooperation on irregular migration, maritime security, science and technology, healthcare resilience and clean energy transition. The agreement also includes cooperation on quantum technologies, digital innovation, space security and hydrogen development to strengthen economic and security resilience.
Why does it matter?
The treaty reflects a broader trend in European security policy, where cybersecurity, technology resilience, energy security and defence are increasingly treated as interconnected challenges.
As concerns grow over hybrid threats, disinformation campaigns and critical infrastructure vulnerabilities, governments are seeking closer cooperation across both military and civilian domains.
Cooperation on missile production, sanctions enforcement, disinformation response and emerging technologies signals a long-term effort to strengthen Europe’s eastern flank while reducing dependence on fragmented supply chains and external strategic vulnerabilities.
