Deployment Requirements

These requirements refer to systems that require a Proxyclick client to be installed to manage communication between your access control system and Proxyclick.

Cloud-based access control systems do not need our client software, and the below steps can be skipped.

The access control client must be installed on a Windows machine with access to the public internet. The client needs to be always on to function correctly.


Proxyclick's access control client is lightweight and has low hardware requirements. A machine of this specification, or greater, will run the client comfortably:

  • Dual-core @ 2GHz
  • 4GB RAM
  • 10GB minimum free disk space


The software requirements for the Proxyclick access control client are as follows:

  • Windows 8.1, 10, Server 2012, Server 2016, and Server 2019
  • Latest service packs and updates recommended
  • .NET Framework v4.8 or higher


The client is configured in polling (outbound) mode and will establish communication with Proxyclick cloud servers via an outgoing connection.

This means you do not have to open port 443 on the public side of the network unless outbound traffic is restricted via the firewall.

Outbound traffic filtering

If outbound traffic is restricted, ensure the client can connect to Proxyclick cloud servers over port 443. Our clients do not need any inbound port forwarding from the public internet.

Traffic to the following IP addresses must be allowed. Depending on your region, the IPs used will be different; select the closest region to your installation. There will always be 4 IP addresses: two global and two region-specific.

The domain (port 443) will need unblocking for all the below IPs.

Connection to the Access Control system

The Access Control system API or SDK port needs to be accessible from the machine our client is installed on, and your Access Control Administrator must confirm the port is available. When possible, the specific access control system’s documentation will note a method of testing this connection. Note that the port is often configurable.

The above covers the requirements for the Proxyclick client to communicate with Proxyclick servers successfully. The client then needs to be connected to the ACS server on the secure side of the network.

Notes on Proxyclick client to Proxyclick server communication

  • The client and server utilize mutual authentication to communicate securely. Both the client and server have to trust each other's certificate and communicate over TLS-encrypted channels (WebSockets)
  • The two rows where we mention ‘Global’ are used for specific outbound HTTPS traffic, we do not guarantee a specific region, but these are hosted in EU data centers.

If the above hardware and software requirements have been met and you are confident in the network set up, you can mark them as complete on your checklist.
