Valarian Raises $50 Million for Sovereign Infrastructure Control Layer

UK-based sovereign infrastructure company Valarian announced on Tuesday that it has raised $50 million in Series A funding. The company, which previously raised $20 million in seed capital, said the latest funding comes from New Enterprise Associates (NEA), Lightbank, XTX Markets, Sequel, LitVC, and angel investors Gokul Rajaram and Nikesh Arora. The new investment will fund Valarian’s expansion and enable it to enhance its platform. Valarian has developed a control layer called ACRA, which sits atop Kubernetes to govern AI models, agents, and other workloads running within an organization’s environment. Each workload is placed in its own enclave with a dedicated policy stack covering workload identity, user identity, default-deny network segmentation, policy enforcement, short-lived secrets, scoped messaging permissions, and audit logging. The platform is designed to be cloud-agnostic, running the same way on public cloud, on-premises or air-gapped networks, and customers hold their own encryption keys so that Valarian itself has no access once a deployment is live. Misbehaving or compromised workloads can be isolated, sealed or revoked at runtime without taking down the surrounding system, and the architecture is meant to work with existing applications rather than requiring them to be rebuilt. Valarian offers two deployment tracks: Valarian Enterprise, aimed at regulated industries; and Valarian Defence, aimed at government and military customers. “The intelligence layer of Western institutions is consolidating: quietly, contract by contract, department by department, into systems those institutions do not control,” said Max Buchan, CEO and co-founder of Valarian. “We built Valarian because sovereignty isn’t a feature you can add later. It’s architecture you have to build from the ground up. This round gives us the capital to take that architecture to the organisations that need it most, at the moment they need it most.” Related: Cybersecurity M&A Roundup: 37 Deals Announced in June 2026 Related: QIZ Security Raises $17 Million for Cryptographic Governance Platform Related: 8Layers Raises $2.9 Million for Identity Security Platform
