This article addresses issues related to advanced security policies and zero trust software that may prevent Snow software from functioning correctly.

Issue

• Advanced security policies preventing the Snow Agent from executing.
• Snow infrastructure communication is blocked.
• Snow browser extensions are blocked.

Cause

Many companies are implementing advanced security policies, which can include changes to TLS and cipher suite settings at the network level, and the implementation of security policies such as FIPS. It is crucial to test these policies and any associated security software. Without proper testing, the Snow Agent and its network traffic may be mistakenly identified as malicious.

Examples of zero trust security software that have been known to prevent the Snow Agent from executing or communicating correctly include:

• CrowdStrike Falcon Zero Trust
• Illumio
• Tanium

NOTE: This is not an exhaustive list. Other security software and strict network and group policies may also cause similar issues.
