Microsoft Edge slow website load times when Endpoint Security is on

[GC82]

Hello there!

I have a user on Windows 11 24H2 with Microsoft Edge 130.0.2849.46 and Cisco Secure Endpoint 8.4.2.30317.

The user is experiencing issues with slow load times in Microsoft Edge. For example, it takes 5-7 seconds to load google.com. It can also take 5-7 seconds to open Settings or the F12 developer tools.
If I disable Cisco Secure Endpoint, Microsoft Edge works without any issues.
There are not the same issues in Google Chrome, for example.
I've tried Edge.Dev and also disabled all extensions - with no effect - same issue.

Does anyone know of a similar problem and know of a solution?

Version 8.4.4 includes a fix to the issue. It has an ETA of January 2025.

So, is there no solution for this problem at the moment? Should we downgrade to 8.4.0 then, if I understood correctly? Where did you get this information about version 8.4.4?

As far as I'm aware, there is no SE version what works well with 24H2. My testing showed the issue even with the 8.2.x train.
If you can't wait for the fix, you have the option to make a TAC case, and have them disable the offending exploit prevention module for your organisation.

We got a TAC update last night. The issue will be resolved in Secure Endpoint connector 8.4.4. The release is expected somewhere in January 2025. As usual, timelines can change. Hopefully they deliver in in Jan '25.

Having the same problem with Edge, we discoverd Cisco Secure Endpoint to slow down openig files from Outlook 365 and Adobe Acrobat as well.

any news to delivery date of Secure Endpoint Connector 8.4.4.?

[GC82]

Unfortunately, I have yet to receive information about a release of version 8.4.4.

Hi,

I resolved the issue by installing version 8.4.4. If you'd like, you can open a TAC case and have them activate version 8.4.4 in your tenant. @Thomas Salzer

we just got released the version 8.4.4 and can confirm that the problem is solved with this version. Edge opens web pages fast, Outlook attachments are opend fast, too.

[GC82]

Good to hear. I'm still waiting for version 8.4.4 to hit our solution.

This also affects Adobe Reader with app container on, happens with cisco 8.4.3 as well.

I reckon any form of virtualization/containers protection is affected.

Hi, just to let everyone know - version 8.4.4 now seems to be generally available.
