For the downloads page, the IP addresses listed above are just examples. The download pages are served by CloudFront (CDN), so the IP addresses are dynamic depending on the client's location.

Proxy Access

If the Endpoint Agent is behind a proxy that performs full TLS decryption, the signing certificate of the proxy must be accessible to the browser running the Endpoint Agent, or the sites above must be added to an exclusion list so that HTTPS interception is disabled.

For Windows Users: Ensure the SYSTEM account can authenticate or exempt from authentication the domains for the proxy. The te-proxy utility is provided as a workaround, but is not the recommended approach.

Memory

The Endpoint Agent requires less than 50 MB of RAM and less than 500 MB of disk space.
