Hi @karthikeyanB ,

• LEEF (Log Event Extended Format)—The LEEF event format is a proprietary event format, which allows hardware manufacturers and software product manufacturers to read and map device events specifically designed for IBM QRadar integration.

• CEF (Common Event Format)—The CEF standard format is an open log management standard that simplifies log management. CEF allows third parties to create their own device schemas that are compatible with a standard thatis used industry-wide for normalizing security events.

I wouldn't be able to tell you which one would be better over the other.  Maybe other users can help you make a better comparison between the 2.

If you're not using an IBM QRadar SIEM then I'm guessing that you will go with CEF ;)

Cheers !

Hello,

I would say it really depends on your SIEM and what it can ingest better.
