On-premise HRMS or cloud: one product, two editions
An on-premise HRMS runs on servers your organisation controls instead of the vendor's cloud. Ergenza ships one build in two editions: every plan runs on our cloud, and Enterprise customers can run the same product on-premise in their own environment, with the same modules and no separate fork.
Cloud or on-premise: what differs
The software is identical in both editions. What changes is who operates it and where the data lives.
- Cloud: we host and update it, it is available on every plan, and data is stored in our cloud.
- On-premise: your team runs it in your environment with our support, it is available on the Enterprise plan, and data stays in your infrastructure.
What the customer runs on-premise
The on-premise edition is the same Ergenza application and its PostgreSQL database, installed in an environment your IT team controls.
Before an install we agree the environment and the upgrade process with your IT team, and support terms are set in the contract. AI features can be pointed at a locally hosted model.
Controls in both editions
- Company sign-in through OpenID Connect, and passkeys (SAML 2.0 is on the roadmap)
- Automatic user setup from your identity provider (SCIM)
- Your own sign-in rules: passwords, lockout, session and idle timeouts
- A change history for each company that cannot be rewritten
- Each company’s data kept apart by the database itself, and sensitive fields encrypted
How to choose
- Choose cloud if you want us to run hosting and updates.
- Choose on-premise if your policy requires HR data to stay in your own infrastructure and you have a team to operate it.
- Most evaluations start on a cloud workspace set up with you, including for on-premise customers.
Questions and answers
- Can we run Ergenza on our own servers?
- Yes, on the Enterprise plan — this is called on-premise. Every other plan runs on our cloud. It is the same product either way.
- Can we use single sign-on?
- Yes. Staff can sign in with your company’s identity provider through OpenID Connect, or with passkeys. User accounts can be created and removed automatically (SCIM). SAML 2.0 is on the roadmap.
- How is our data kept separate from other customers?
- The database itself keeps each company’s data apart (PostgreSQL row-level security), not only our code. Each company has its own change history, and any edit to it shows. Sensitive fields are encrypted with AES-256.
- Does Ergenza hold security certifications?
- Not yet. Ergenza is in early access and does not hold SOC 2, ISO 27001 or other third-party certifications.
- Does Ergenza include AI features?
- Yes. You can ask questions about your HR data in plain words and forecast future headcount. The AI can also run on a model hosted on your own servers.
