# Before you begin

Before you start setting up Nexthink, read the following prerequisites.

### Understand the Nexthink architecture

The Nexthink Infinity Platform employs a unique architecture to facilitate automation and remediation across all IT environments.

See the [Nexthink Infinity Platform](/platform/overview/nexthink-infinity-platform.md) page for a high-level description of this architecture. For more detailed information about the components, visit the [Infinity Specifications](https://edocs.nexthink.com/nexthink-infinity/infinity-specifications) page.

### Review Security and Legal policies

#### Security considerations

Nexthink takes information security seriously, as shown by the following key highlights of the Platform:

* Nexthink uses dedicated services and databases to ensure data segmentation for single-tenant components.
* Application services use cloud-native techniques to segment tenant data in dedicated services and database tables.
* Service mesh traffic is automatically encrypted with mutual endpoint authentication using mTLS protocol.
* Nexthink ensures fine-grained role-based access control at the application layer.

Nexthink has also invested significant resources in obtaining several cybersecurity certifications. To learn about these certifications, visit the [Security Portal](https://docs.nexthink.com/security/compliance/).
