# Where does Cosine run?

**Cosine can run anywhere your organisation needs it — from the fully managed Cosine Cloud to private VPC or on-premise deployments.** This flexibility ensures teams in every industry, including regulated sectors, can use Cosine securely and compliantly.

***

### Deployment options

#### Cosine Cloud

The fastest way to get started. Cosine Cloud is a fully managed SaaS platform hosted by Cosine, ideal for teams that want instant access without infrastructure setup.

* Fully managed by Cosine
* Continuous updates and monitoring
* Secure, isolated workspaces for each organisation

#### VPC deployment

For organisations with stricter compliance requirements, Cosine can be deployed inside your **virtual private cloud** (AWS, Azure, or GCP). This keeps all repositories and data within your own infrastructure while still benefiting from managed updates.

* Data never leaves your environment
* Managed deployment and maintenance by Cosine
* Ideal for finance, healthcare, and enterprise SaaS

#### On-premise (air-gapped)

Cosine also supports **fully air-gapped, on-prem installations**, where neither model weights nor data have any external connectivity. This is designed for **defense, government, and critical infrastructure** customers who require absolute data isolation.

* Deployed on your own hardware
* No external dependencies or egress
* Supports custom post-training on proprietary data and languages

### Security and compliance

All deployment modes follow the same security foundations:

* Encryption in transit and at rest
* Role-based access controls
* Isolated execution environments
