Net Nanny is one of the best known commercial packages and is now also available for the Mac. The basic operation is the same as rivals, but with the extra cost you get added features such as free technical support, remote management (allowing you to change the settings online meaning you don’t have to access your child’s computer) and blocks on adult-rated videogames. The software also automatically sets (and keeps) major search engines to safe search mode. However, given the price (which is an annual subscription rather than a one-off purchase), it may be worth trying free alternatives first.
