Internet Browser Requirements for RelativityOne

RelativityOne is a cloud based electronic discovery platform. While it is available for Mac users, an Apple OS will not support the use of Relativity Desktop Client; RelativityOne Staging Explorer [used to quickly upload or download files to and from a workspace]; or RelativityOne VPN Client [used to provide a secure connection to the Relativity network].

Internet Explorer 11 can currently be used for Relativity but it will affect the appearance of the workspace, and slow down performance. As of January 2021, IE 11 will no longer be supported for RelativityOne. Use the latest versions of Chrome, Firefox, Edge or Safari instead.

The default versions of Firefox and Safari will block some pop-up windows for RelativityOne.

RelativityOne uses HTTPS for secure communication over the internet in a browser on a user's computer. (You may see HTTPS referred to as Port 443. An operating system assigns port numbers to specific processes. Port 80 is used for HTTP, unsecured internet communications, port 443 for HTTPS.)

Relativity Desktop Client and Staging Explorer use a protocol developed by Aspera (IBM's data streaming service) to transfer data to servers. The Fast Adaptive and Secure Protocol (FASP) uses port 33001. The advantage of using FASP is its built-in security features which do not slow down the speed of data transmissions. A network firewall may need to be updated to allow multiple UDP ports to communicate with Relativity's Aspera servers. [A UDP - user datagram protocol - allows applications to transmit data across a network, and is often used for data streaming since this protocol doesn't confirm that data packets are received.] In order for the data transfers to the Aspera servers to take place fully qualified domain names (FQDN) must be specifically approved or 'whitelisted'. [A FQDN includes both the host and parent domain name - e.g. .]
