The WSA replaces all, or most of these devices in your network:
Firewall
Webproxy
Anti spyware
Antivirus

Policy management
As you can see, it’s more than just a regular proxy server.
The internet provides a lot of websites, good websites and bad websites. There are a lot of websites which are not work related for a lot of companies. If you want to limit or block those websites for users, the WSA is the product for you. Limitation can be time based, bandwidth based, user based or category based (79 categories).
