Content Filtering

The ZyWALL can block web features such as ActiveX controls, Java applets and cookies, as well as disable web proxies. The ZyWALL can block or allow access to web sites that you specify. The ZyWALL can also block access to web sites containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude a range of users on the LAN from content filtering.

You can also subscribe to category-based content filtering that allows your ZyWALL to check web sites against an external database of dynamically updated ratings of millions of web sites.

Anti-Spam

The ZyWALL’s anti-spam feature helps detect and mark or discard junk e-mail (spam). The ZyWALL has a whitelist for identifying legitimate e-mail and a blacklist for identifying spam email. You can also subscribe to an anti-spam external database service that checks e-mail against more than a million know spam patterns.
