Editor's review of Suntereo

Although this easy-to-use parental software effectively blocks improper Web sites, its lack of security is more than we can forgive.

Sporting a stylish, secure interface, Suntereo makes navigation painless. The program lets us create a list of trusted Web sites manually or simply by turning on the Learning mode. Beware when enabling its Learning mode, because it automatically adds in all visited Web sites to the trusted list. To browse or preview the Web sites without adding it to your list, you'll want to use Bypass mode instead.

Suntereo worked well in tests and displayed its own blocked page when a site was forbidden. While it is password-protected, Suntereo doesn't require the password to uninstall the program. The program only works with Internet Explorer. With that in mind, this application is still useful to parents of young kids.
