This document provides endpoint information needed to allow Silo connections from behind a firewall. If your environment utilizes a firewall to manage network traffic, you may need to implement an exception for ALL applicable entries.

 

 

Domain Names

Domain names can be broadly whitelisted using a wildcard entry as shown in the following examples:
 

*.authentic8.com

*.a8silo.com

*.getsilo.com

 

Connection Type

Silo uses a TLS connection over port 443 (HTTPS) with the Web Client, while the Installed Client uses a custom network protocol over port 443. We recommend creating a full exception in order to prevent connection issues with various Silo client types.

 

SSL Inspection

SSL inspection (e.g. SPI/DPI) will need to be disabled for Silo connections.

 

NOTE: This rule does not apply to Silo Windows Client version 2.9.13 and newer. Please see this article:

https://authentic8.freshdesk.com/a/solutions/articles/16000100713 for additional information.

 

External API

Some customers may need to whitelist our External API endpoint in order to use other Silo services. 

 
An exception for the following domain will be needed: extapi.authentic8.com
