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.

Stormwater and sewer networks are under increasing pressure as a result of climate change, urbanisation, ageing infrastructure and more stringent compliance measures. At ManholeMetrics we offer affordable level monitoring and insights for cities, utilities, highway and rail authorities, to help with these growing operational, planning and compliance needs. Our radar-based level sensors are much like a smoke alarm—low-cost, long-life (10+ years) and easy to install (<10 mins with basic tools and our app)—making high-volume deployments possible. This data enables our platform to deliver powerful network insights. These include real-time and predictive alerts for overflows, blockages, inflow and infiltration to allow for targeted interventions. This network data in turn can inform capacity monitoring studies, capital improvement projects and hydraulic model calibration. Learn more about turning network insights into action—reducing costs, improving compliance, operations and planning—at www.manholemetrics.com and email us at contact@manholemetrics.com to book a demo.
