Valarian

Valarian builds infrastructure for organisations operating in high-trust, high-stakes environments. Our core product, ACRA, is a secure, compartmentalised backbone designed to run and protect mission-critical applications — now proven at the edge in portable GPU clusters as well as in the cloud and on-premise. We developed ACRA when existing infrastructure failed to meet real-world risk — where segmentation breaks down, audit trails disappear, and lateral movement cannot be contained. Valarian is a UK-founded and UK-led company, and backed by leading defence and national security investors. We are a homegrown team with backgrounds across defence, secure communications, high-assurance systems, and enterprise software — engineers and operators who have worked in environments where a lost signal or a missed audit can carry real consequences. We design like users because we’ve been them.
