I just received this notification this morning.
Hello valued Meraki customer,
Meraki will be discontinuing support for versions 1.0 and 1.1 of the Transport Layer Security (TLS) protocol used by wireless devices to communicate with Meraki Authentication. In order to facilitate the provisioning of enhanced security features, we will be requiring all customers to upgrade, at a minimum, to TLS version 1.2. This change will only affect wireless devices using TLS versions 1.0 and 1.1 when connecting to the Meraki Authentication server.
Due to security requirements, we do not have the ability to determine which of your devices, if any, are currently using the prior versions of the TLS protocol. In an effort to help you identify these devices, we will be temporarily disabling support for TLS 1.0 and 1.1 as a test. This action will cause a planned disruption of device connectivity, which will begin at 12:00 am PST on April 19, 2023 and end at 12:00 am PST on April 20, 2023. Any devices that experience an issue with connectivity during the test period may be using the prior versions of the TLS protocol.
Final retirement of TLS 1.0 and 1.1 will take place on May 17, 2023.
Please plan for the 24-hour test period accordingly. If any of your devices experience an issue with connectivity during the planned test period outlined above, you may be required to upgrade to TLS 1.2 or a later version. To help you determine where potentially-affected devices may be located, a list of your organizations with Meraki Authentication enabled can be found at the bottom of this email. More information about the test and how to upgrade your protocol can be found in our FAQ
If you need assistance or have additional questions not covered in the FAQ, please reach out to Meraki Technical Support at email@example.com
