For most companies, “just use our cloud” is a reasonable answer for identity. For regulated finance, healthcare, government, and defense, it is a non-starter. Identity is the one system that controls access to every other system — and handing it to a multi-tenant SaaS means trusting a third party with the keys to everything.
This is the case for on-premise IAM: identity and access management that runs entirely inside your own perimeter, with no dependency on an external cloud to authenticate your people.
The data-residency problem
Identity data — who your people are, which devices they use, every access decision — is the most sensitive telemetry your organization produces. Shipping it to a shared SaaS tenant creates three problems at once: you accept the vendor’s region and retention rules as your own, you inherit their outages as your outages, and you lose the ability to prove, on your own terms, that the data never left your control.
For many teams this is not a preference — it is a legal or contractual obligation. Sovereign workloads, classified environments, and air-gapped sites simply cannot route authentication through the public internet.
What on-premise IAM actually means
Running IAM on-premise means the control plane — the service that issues identities, verifies sign-ins, and stores audit logs — lives on hardware you own and operate. Not mirrored to a vendor cloud. Not “single-tenant but hosted by us.” Yours.
With CyberCyko’s on-premise deployment, identities, hardware-key registrations, and audit trails all stay inside your boundary. The passwordless experience is identical to the cloud product — the only difference is where the control plane runs.
Passwordless login that works offline
The objection to on-premise identity used to be that modern auth needs the internet. It does not. CyberCyko sign-in is a local cryptographic challenge: the user’s device signs a one-time challenge with a key sealed in its hardware (a TPM or Secure Enclave), and your control plane verifies the signature locally.
Because there is no round-trip to an external service, an air-gapped site with no outbound connectivity signs its people in exactly the same way — with a fingerprint or a face, not a password or an SMS code that could be phished.
On-premise vs private cloud
On-premise is the strictest model, but not the only isolated one. If your rules allow cloud but forbid multi-tenancy, a single-tenant private-cloud deployment runs a dedicated instance inside your own VPC on AWS, Azure, or GCP — the isolation of on-prem without owning physical hardware. Choose on-premise when data must stay in your building; choose private cloud when you want that isolation without a rack to maintain.
