If you want to detect/alert the requests having empty value for Referer Header, you can use following:

Subject: Match criteria for requests with NO referer?
I'm trying to create a policy where one of the match criteria is that the request has NO referer.
There are several match criteria related to referers, but if I try to leave the field blank, SecureSphere won't let me save the policy and returns the message
- Invalid match criteria parameter value - parameter value may not be empty
- One of the predicates has an empty list and cannot be saved.
So, how can I filter for requests with no referers without listing every possible referer and using the "Exclude All" operator?
Thanks in advance!
