Model independence
Your models, not a vendor's. Run open-weight or frontier models, swap or replace on your terms, and never worry about them training on your data.
Your organisation's second brain, on hardened Kubernetes. Keep control of your data, agents, and business as you scale.

Your models, not a vendor's. Run open-weight or frontier models, swap or replace on your terms, and never worry about them training on your data.
Give a model, an agent or a person access to exactly the systems they need — nothing more. The keys stay yours, so not even we can see in.
Your control layer is the trust boundary you own. It stays identical whether you run on AWS, Azure or your own metal. You control it, no matter where it runs.
The race to see who can adopt AI the fastest is well underway. CEOs are demanding more speed, developers are tokenmaxxing, and the security team is scrambling to keep customer PII from leaking into a prompt. The result: companies are handing their institutional knowledge to Anthropic, OpenAI and Google.
Valarian is building the infrastructure to regain control over your high-consequence systems.
It turns Kubernetes into a hardened, governed environment and wraps every workload (agent, model or service) in policy you define once and enforce everywhere.
ACRA
ACRA is Valarian's control architecture: the enforcement layer between your intelligence and everything it can reach. It governs one workload the same way it governs your whole estate.
01 · Intelligence
Your agents, your models, your applications all run inside ACRA, on your cluster. Each one reaches your deals, your data and your systems to get its job done.
02 · Control
Every workload runs inside its own enclave with a dedicated policy stack: workload identity, user identity, network isolation, policy enforcement, secrets, messaging and audit. Each control is enforced independently, scoped to that workload alone — protecting its models, its data and its keys.
03 · Scale
More agents, more workloads, more compute: each one inherits its enclave the moment it deploys. Nothing to assemble, nothing to re-secure, on any cluster, in any cloud. We're ready when you are.
Deployed for
Privileged government and defence workloads run air‑gapped, with keys held in‑country.

Regulated enterprises run trading, communications and AI workloads with every access auditable end to end.

What platform teams and CISOs ask before ACRA runs in production.
Kubernetes solved orchestration; ACRA solves governance. It extends the cluster with workload-level control: inherited policy, default-deny boundaries, containment, telemetry and audit. The environment itself enforces posture, rather than tooling bolted around it. Kubernetes is the primitive; ACRA is the posture.
The per-workload policy stack comprises seven layers: cryptographic workload identity (SPIFFE/SPIRE), user identity (your internal IdP), default-deny network isolation (Cilium + Istio), admission and workload policy enforcement (Kyverno and gateways), short-lived scoped secrets (Vault), per-workload messaging permissions (NATS), and audit and evidence (platform audit logs). OpenTelemetry provides observability across every layer.
You do. Each deployment is cryptographically unique and the customer holds the keys. Even Valarian cannot access systems after launch. Governance emerges from enforced boundaries, not privileged access; securing the environment should not require admitting a new privileged actor into it.
Yes. ACRA is a cloud-agnostic control architecture: the same governance, containment and audit posture across clouds, on-prem and air-gapped estates, deployed where you need it to run and able to keep operating if connectivity drops. The cloud remains the substrate; the trust boundary belongs to you.
It gets contained. Specific workloads or whole environments can be isolated, sealed or revoked at runtime without destroying the system around them — a non-destructive kill switch, enforced at the infrastructure layer. Every powerful machine eventually gets a circuit breaker; AI will not be the exception.
No. ACRA extends Kubernetes — it does not replace it. Applications, workloads, teams and AI inherit the environment's posture by default; the number of applications grows, the control architecture does not. Every application should not become a new security project.
