# Before you start

> Checklist of environment prerequisites and system requirements before deploying EJBCA.

Verify your environment meets these requirements.

## Supported hardware

* CryptoHub, `7.0.3.x` or later.

## Supported operating systems

* Linux

## Required access

* An account on the CryptoHub with administrator permissions to deploy new services.
* 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 EJBCA server to the CryptoHub, specified by FQDN (for example, `cryptohub.example.com`) or CIDR (for example, `10.0.0.0/24`).

<Warning>
  TLS inspection or SSL proxies can break mutual TLS handshakes. Exempt the CryptoHub FQDN(s) from inspection. Configure the CryptoHub with a FQDN so the exemption applies.
</Warning>

## Other

* Java 17 or 21
* EJBCA (This document does not include the EJBCA installation process; it should already be installed on the server.)
