Transport Layer Security (TLS) 1.0 and 1.1 are security protocols for establishing encryption channels over computer networks, ensuring data integrity and privacy. Due to regulatory requirements and security vulnerabilities, Atera will no longer support these deprecated versions as of November 1, 2021.
This articles describes:
- What's going to happen
- Why this is happening now
- What you can do
- Operating Systems (OSs) that will not be supported
What's going to happen?
Agents on legacy OSs not supporting TLS 1.2 and above will stop working. This means the machines will no longer be monitored and you will not be able to manage them.
Why this is happening now
As always, your security and privacy are of the utmost importance to us. Our decision to deprecate support for TLS 1.0 and 1.1 is to ensure Atera is as secure as possible. That's the bottom line. As always, we'll continue to follow strict security standards to ensure none of our customers are breached.
Ok, so what can I do about it?
If the OS does not support TLS 1.2 and above, we recommend upgrading to a version that does.
For OSs that do support TLS 1.2 and above, please make sure you've downloaded the latest patches to ensure smooth operation.
Note that Microsoft advises customers to remove TLS 1.0 and 1.1 dependencies in their environments as well as disabling them at the OS level—if possible—as soon as possible.
Also note that while TLS 1.2 has been disabled for Windows Server 2008 and Windows 7 (WS2008 R2), you can re-enable it. For more information, see this article from Microsoft.
These operating systems will not be supported
The following OSs do not have any versions that support TLS 1.2 and above. As such, any agents on these OSs will stop working as of November 1, 2021.
- Windows XP
- Windows XP SP3
- Windows Vista
- Windows Server 2003
- MacOS X 10.9 and under
