A $50.0M Series A funding round has been secured by Valarian, the UK-founded company developing secure infrastructure for high-trust, high-stakes environments. Its core product, ACRA, provides a compartmentalised backbone designed to run and protect mission-critical applications, now proven across cloud, on-premise, and portable GPU clusters at the edge.
Valarian, backed by leading defence and national security investors, developed ACRA to counter real-world risks where existing systems fail to contain lateral movement or maintain audit trails. The company's homegrown team brings backgrounds from defence, secure communications, and high-assurance systems.
