N-sight RMM: Advance Notice for Ending Support for TLS 1.0 and 1.1

As N-able continually reviews its security posture and protection of partners, we have decided to retire support for TLS 1.0 and 1.1. Therefore, effective March 1, 2023, N-sight RMM will no longer support Transport Layer Security (TLS) 1.0 or 1.1 for Agent to RMM console communication. 

Microsoft recommends that TLS 1.0 is deprecated in favor of TLS 1.2 or higher. See https://learn.microsoft.com/en-us/security/engineering/solving-tls1-problem for more information.  

TLS 1.0 and 1.1 were deprecated beginning in March 2020. N-sight RMM has continued to support TLS versions 1.0 and 1.1 to ensure backward compatibility for endpoints that use operating systems that don’t support TLS 1.2 or higher.  

On March 1, 2023, all endpoints that communicate to the RMM console using TLS 1.0 or 1.1 will no longer be able to connect and will start to show as offline or overdue in the dashboard.  

Updating Windows and Linux 

  • Windows Operating Systems 

Affected Operating Systems: Windows 7, Windows Server 2008 and Windows Server 2012. There is extensive information online that provides Microsoft update instructions: Partners can follow this Microsoft article to update the affected operating systems to TLS 1.2. 

To help prevent any issues, N-sight has created a custom script that partners can use to enable TLS 1.2 for a device. Visit the Success Center at https://success.n-able.com, then look for “Enable TLS 1.2 for a device” in the Automation Cookbook. Download the script to your computer, then upload it in N-sight RMM via Settings > Script Manager and add it as an automated task to the device you wish to update.

  • Linux Servers on Legacy v1 Agent 

Linux servers using the legacy v1 monitoring agent may also be affected. Please update any Linux servers to the latest v2 Linux agent version, and check that it is configured to use TLS 1.2, to avoid any issues related to TLS 1.0/1.1.
