On macOS Big Sur, ​ETP Client​ may show an unprotected status when routers or wireless networks are configured to send IPv6 stateless address auto-configuration (SLAAC) messages. While a user can still use the Internet in this situation, ​SIA​ threat protection may be temporarily disabled on the user's computer. ​Akamai​ is currently investigating a solution for this issue. However, you can work around it by completing one of these steps:

  • Disable IPv6 on computers with macOS Big Sur.

  • Disable IPv6 SLAAC messages on routers and configure the routers to use DHCPv6.

An ​SIA​ administrator can access and download the latest version of the client, as well as previous versions.
