Problem
With the release of the Google Chrome and Microsoft Edge version 124 update, a number of sites may display SSL errors. This is due to a change within this update, within the section which "added a general availability of X25519Kyber768 key encapsulation". This is causing a number of website's Server Name Information (SNI) requests to be misread by Netsweeper's filter. If this is the case you will see the SSL error message as shown below or a similar message will appear:
Solution
If you are running the Client Filter version 11.60 or earlier or if you run your own Netsweeper Server of 7.2.14 or earlier - you could be affected by this issue. If this is the case, you will need to upgrade to one of our newer versions which has had the update fix applied to it.
Client Filter
To resolve this you will need to upgrade your Client Filter to version 12.60 GA or higher.
Netsweeper Server
If you are running your own on premise Netsweeper server and you are on Enterprise Linux 6, you would need to upgrade to 7.2.16 GA. If you are running on Enterprise Linux 8 then you can upgrade to 8.2.6 GA
