Same Websites blocked and allowed in wrong catagory

Hi, 

We have setup network DLP before the firewall which is connected like, Endpoint >> L2Switch >> Network DLP (centos uses Proxy) >> Sophos Firewall. 

For Example website Web.workline.hr

This website comes under the hrms category which is allowed in Sophos firewall. But sometimes this same website category gets changed to business category after it passes through NDLP server and is blocked by firewall as business category is not allowed by firewall as per firewall policy.

In the nutshell same website sometime shows in category A and sometime catagory B, when traffic flows through Network DLP server (network DLP uses it's own certificate for handshaking).

  • Hi, 

    Thanks for your reply. 

    My Network DLP (transparent proxy) just monitors the packets sent from endpoints. And my network DLP does not have any option for url or catagory filtering. How do I check what is changing and why firewall is detecting same url in 2 different catagories.

    May be it is because those urls are not in the global database of Sophos?
