How to block AnyDesk and TeamViewer via Harmony Endpoint Security (v89.10)

AfterMath — Wed, 18 Feb 2026 20:55:02 GMT

Hello CM

We would like to block AnyDesk and TeamViewer communications (web and application) using Harmony Endpoint Security version 89.10.

Currently, these applications are already blocked at the corporate network level via the firewall. However, when endpoints are connected to external networks, they are able to bypass these restrictions.

Therefore, our objective is to enforce this block directly on the endpoints, ensuring these tools remain blocked regardless of the network they are connected to.

Could you please advise on the recommended policy configuration to achieve this?

This is possible. I assume endpoint software is centrally managed by you.

You can follow:

@AfterMath

The best way is to block using blade application control.
