Your own cloud —
confidential and crystal clear.
Klarcloud isn’t a cloud you rent. It’s a confidential, sovereign cloud built on infrastructure you own and control — where no provider, operator, or outsider can ever see your data, even while it’s being processed.
See how it works
One cluster. Your infrastructure. Sealed end to end.
We stand up an industrial-grade cluster across the infrastructure you already own — on-premise, any cloud, or both — and seal it so tightly that your data stays encrypted even while it is being processed.
Kubernetes cluster
One auto-scaling cluster on a private VPC, wired together by an end-to-end encrypted tunnel network.
Hardware-sealed enclave
Every node runs inside a hardware-sealed enclave. Memory and processing are encrypted at the silicon level — invisible to the host.
Your infrastructure
Bring your own: an on-premise node, standard trusted hardware in any public cloud, or a mix. You own it — we never hold it.
The result: a cloud that behaves like the big providers’ — elastic, managed, industrial-grade — except you own every layer of it, and no one else can see inside.
Complete protection
Your data stays protected in every state.
Most “secure cloud” only protects data at rest and in transit — leaving it exposed the moment it is actually used. Klarcloud protects all four states, including the one everyone else leaves open.
In use
Sealed inside encrypted memory while it runs — never exposed as plaintext to the host.
In processing
Shielded at the hardware level as it is computed, invisible to the layer beneath it.
In transit
Encrypted end to end as it moves between nodes, across your own and public infrastructure.
At rest
Locked with keys only you hold — released to no operator, ever.
Why it matters
Without confidential computing, your data is visible to many players.
Ordinary cloud protects your data at rest and in transit — then leaves it wide open the instant it’s used. Here’s the difference.
Provable, not promised
Don’t trust. Verify.
Before a single secret is released, the hardware itself proves — cryptographically — that the environment is genuine and untampered. Change one byte of the workload, and access is refused automatically.
- Hardware-rooted proof, not a checkbox
- Keys released only to a verified environment
- Tampering breaks the proof — and blocks access
Secret released
Access refused
Provider-blind by default
The cloud can’t look inside.
Your workloads run inside a sealed enclave. Even the operator hosting the hardware — with full physical access — sees nothing but ciphertext. Not the memory. Not the keys. Not the data.
It removes the one assumption every ordinary cloud quietly asks you to make: that you trust whoever runs the machine.
Sovereign by design
Independence that isn’t just a label.
Sovereignty isn’t a sticker on a data center — it’s who can technically reach your data. Klarcloud is built so the answer is: only you.
No single point of trust
Run across your own infrastructure and European clouds — no one provider holds your keys or your fate.
Built for compliance
Designed around GDPR, BSI and data-residency requirements from the ground up, not bolted on.
