# Before you start

> Pre-deployment checklist and environment verification steps.

Verify your environment meets these requirements.

## Supported hardware

* KMES Series 3, application version `6.3.1.3` or later, with the initial setup completed (including loading a Platform Master Key, setting up the network, etc.), and the **Data Protection** license enabled.

## Supported operating systems

* Windows 10 or later
* Linux

## Required access

* An account on the KMES with administrator permissions to create roles, identities, TLS PKI, and update system settings.
* Local administrator/root access on all hosts where you install or configure components.

## Network and firewall

* Allow outbound TCP port **2001** (default Host API port) from the machine running the Futurex File Encryption Agent to the KMES Series 3, specified by FQDN (for example, `kmes.example.com`) or CIDR (for example, `10.0.0.0/24`).

<Warning>
  TLS inspection or SSL proxies can break mutual TLS handshakes. Exempt the KMES FQDN(s) from inspection. Configure the KMES Series 3 with an FQDN so the exemption applies.
