Hello there.

I hope someone could give me a hint. Due to environment constraints, I need to know what is the OLDEST version of Chrome and/or Edge that supports current (7.5) Qradar web gui. Even 32 bits if exists. Firefox could also work but  the two others are desirable.

I'm afraid product documentation only indicates the latest version supported, and that is "latest".  Not a very usable information I think.

Thanks and best regards.

Google Chrome:
QRadar 7.5 generally works well with Chrome version 40 and newer, thanks to support for modern web technologies. While there's no official minimum version listed, if you're using a version older than 40, you may need to test it yourself to see if everything functions properly.

Microsoft Edge:
The older versions of Edge that used the EdgeHTML engine (versions 12 through 18) might be compatible, since they share some similarities with Chromium. However, compatibility isn't guaranteed-so testing is recommended.

Mozilla Firefox:
Firefox version 50 and above typically work fine with QRadar 7.5. Versions below 50 might still work, but again, you'll want to test them to be sure.

Important Note:
Using outdated browsers can pose serious security risks. Whenever possible, it's best to stick with the latest supported versions to ensure both compatibility and safety.
