Second Front Systems and Valarian Form Strategic Partnership to Accelerate Sovereign Defence Software Deployment Across UK and Europe

As European defence spending reaches €392 billion and NATO members increase commitments, the partnership delivers infrastructure built for autonomy, speed, and control at a critical juncture in Europe's rearmament

LONDON, UK, 10 February 2026 / Business Wire /Second Front Systems (2F), a proven leader in accelerating the adoption and delivery of commercial technology for defence in the U.S. and allied nations, today announced a strategic partnership with Valarian, the U.K.-based sovereign infrastructure company behind ACRA, a platform engineered to enforce control over data, access, and compute.

The timing is critical. While European defence spending undergoes its most significant expansion in decades, rising to €392 billion in 2025, a 79% increase from €218 billion in 2021, European fragmentation has historically undermined cost-effectiveness.

“Modern operations demand more than updated software; they demand controlled environments,” said Enrique Oti, Chief Strategy Officer at Second Front. “Partnering with Valarian allows us to extend those guarantees into sovereign contexts in the UK, EU, and beyond, enabling customers to deploy complex software stacks without external dependency.”

The partnership unites Second Front’s Game Warden® platform, proven in rapidly delivering secure, compliant software into U.S. and allied classified environments, with Valarian’s sovereign enclave architecture, designed to ensure sensitive systems operate seamlessly without bleed.

“European defence institutions aren’t just increasing budgets, they’re demanding infrastructure they can command end-to-end,” said Max Buchan, CEO and Co-Founder of Valarian. “Second Front shares our view: sovereignty isn’t a feature, it’s architecture. As nations invest billions into capabilities they must control absolutely, the providers who eliminate dependency, not manage around it, will define the next generation of defence infrastructure.”

Valarian’s technology ensures sensitive systems do not “phone home,” creating independently controlled sovereign enclaves where mission-critical applications can run with full confidence in their integrity. This complements 2F’s ability to rapidly bring commercial innovation into defence environments while maintaining robust assurance and compliance standards.

Together, 2F and Valarian are enabling a new generation of sovereign-by-design digital solutions with controlled deployment pathways, compartmentalized environments, and audit-first

infrastructure that aligns with European security, jurisdictional, and accreditation requirements while maintaining the speed and flexibility of commercial innovation.
