Hi, this is another issue by following the upgrade to 4.18.23050.5 for fixing the Web content filtering issue. (The previous post can be found from Here .
After upgraded to 4.18.23050.5, the web content filtering has backed to be working again, but now I've just noticed that another web access performance issue, the website loading time in the first time access from a 3rd party browsers are extremely longer than before.
Has anyone got the same issue?

I confirm we have exactly the same issue. Extremely slow and unreliable performance from Chrome and Firefox. Microsoft Edge browser is still working fine.
We have had to temporarily disable the Defender Endpoint Protection feature for now. We have a case open with Microsoft who are investigating.
When troubleshooting we rolled back to last known good previous platform version 4.18.2304.8-0 and that worked OK.
The Microsoft support person mentioned they had at least one other customer in their queue with same problem.

We have exactly the same issue on many clients. Edge is fine.
Hope this hotfix comes soon. We logged a ticket with MS last week but no progress there...

@domokun-au Yes, but you have to have network protection turned on.

The sooner Microsoft roll out this patch the better. We have a lot of clients with network protection enabled in Defender for endpoint and Chrome is basically unusable. I am surprised at the lack of priority on this from MS. The ticket we have open with partner support was updated by MS yesterday to say they have made a breakthrough and will update us soon....

I confirm we are in Australia and affected by this issue. We have switched off Defender Network Protection for now until permanent fix is mainstream. It is off by default so perhaps that is why not so much noise about it.
I am sure Microsoft team have learned a lesson are carefully testing the update this time.....

Quite surprised this isn't a bigger issue, I've been trying to find the cause of this for 2+ weeks. Been looking at firewall's, VPN's etc searching google and reddit. Finally found this have now used your advice and this article to push out the beta channel to staff. Otherwise Chrome is practically not usable. https://www.petervanderwoude.nl/post/easily-managing-microsoft-defender-antivirus-updates-channels/
