The UK’s 2025 Strategic Defence Review (SDR) sets a bold course for strengthening national security in an age of strategic competition, hybrid threats, and technological disruption. With 62 accepted recommendations, the Review lays the foundation for a modernised, resilient, and integrated force capable of meeting tomorrow’s challenges.

At Nexor, we believe that ten of these recommendations are especially pivotal in shaping the future of UK defence:

1. Transitioning to a warfighting posture.

2. Enhancing nuclear deterrence capabilities.

3. Expanding the nuclear-powered submarine fleet.

4. Restructuring the British Army to 100,000 personnel.

5. Investing in AI, drones, laser weapons, and long-range missiles.

6. Establishing a Cyber and Electromagnetic Command.

7. Boosting munitions production through new factories and stockpiles.

8. Digitally integrating armed forces via a “Digital Targeting Web.”

9. Increasing defence spending to 2.5% of GDP by 2027.

10. Launching a new Defence Industrial Strategy and Exports Office.

Of these, four key initiatives closely align with Nexor’s mission and existing capabilities. Here’s how we’re contributing:

Investing in AI, drones, laser weapons, and long-range missiles

• Nexor supports the secure deployment of emerging technologies through trusted data exchange and assurance mechanisms.

• Its cross domain solutions protect the data pathways that enable AI decision-making, autonomous drone operations, and precision weapons.

• By enabling policy-enforced machine learning and secure real-time targeting feeds, Nexor helps operationalise advanced weapons systems in a cyber-resilient way.

• Nexor is a leader in cross-domain data transmission, a key enabler of achieving a complete operational picture, with integrated command and control.

Establishing a Cyber and Electromagnetic Command

• Nexor’s GuarDiode and secure boundary products already form part of the UK’s and NATO’s cyber-resilient infrastructure.

• These products prevent data exfiltration and command injection, making them critical in protecting systems involved in full-spectrum operations and electromagnetic manoeuvre warfare.

• Nexor’s products offer the domain separation and cross-domain guard capabilities essential to the secure operation of critical infrastructure.

Digitally integrating armed forces via a “Digital Targeting Web”

• Nexor’s Protean product provides dynamic, policy-driven data exchange between systems and domains essential to joint-force integration.

• Protean supports attribute-based access control (ABAC) and zero trust architectures (ZTA), enforcing who, what, and how information is shared in real time.

• Nexor’s solutions are designed for real-world coalition interoperability, which is critical to ensuring the Digital Targeting Web can function across national and allied systems securely.

Launching a new Defence Industrial Strategy and Exports Office

• Nexor is a UK-based, entirely sovereign SME, contributing directly to UK strategic autonomy in cyber and information security.

• The company has an established record of exports to allied governments and can help drive UK defence exports under the new strategy.

• Its agile development, collaboration with leading defence prime contractors, and experience with MoD and NCSC programmes position Nexor as a key industry partner in a modernised procurement ecosystem.

A trusted partner in a modern defence ecosystem

The 2025 Strategic Defence Review is more than a roadmap; it’s a call to action. At Nexor, we are proud to contribute to the secure digital backbone of the UK's defence. As threats evolve and technologies advance, our mission remains constant: to ensure that trusted information gets to the right place, at the right time, and remains protected throughout.
