Requirements

Warning: You cannot install a CTERA Agent on a PC running Kaspersky Antivirus software.

Supported Operating Systems and Browsers

For a list of supported operating systems, see Interoperability matrix in the CTERA Knowledge Base.

Note: The operating system must include all Microsoft hotfixes. When the CTERA Agent will be configured as a Caching Agent, it must be installed on a PC running the 64 bit version of Windows 10 or Windows 11.
Windows 10 and 11 running on Arm processors (for example, Surface Pro X) are not supported.

For browsers, the latest two releases of Google Chrome, Apple Safari, Mozilla Firefox, and Microsoft Edge are supported.

Opening Ports on Your Firewall

The CTERA Agent establishes a connection to the portal using TCP port 995. You do not need to open any incoming ports.

When the CTERA Agent is connected to a CTERA Edge Filer (gateway) version 6.0.x or earlier, the Agent establishes a connection to the gateway using TCP ports 995 and 873. To allow roaming PCs and remote offices which are located outside your network to access the gateway, you must open your firewall for the network where the CTERA Edge Filer is located, to allow incoming TCP ports 995 and 873 to the CTERA Edge Filer.
