1. Automatic Server Updates
Definition: The filter manufacturer is has a team that finds objectionable sites, catalogs them, updates their servers and the software automatically updates with the new info without your intervention.  It is impossible to be always 100% protected if you're required to type in objectionable words or sites, or if you have to download updates regularly. Knowing human nature it just won't happen. Ease of use ultimately means that the internet filter provider's server does the work, and professionally maintains the filtering capability.
2. Adult password overrides
Let's face it. Internet filters are not just for kids. A lot of adults get trapped as well. The "adult administrator" feature is really little protection for someone intent on viewing objectionable content. To be really safe, get a filter that provides the capability for adults to NOT overide the filter!

Perhaps the first thing to consider is the methodology used by the filter in Question.

White List Filtering - This method previews sites, adds acceptable sites to the white list (allowable list), and rejects all sites that are not on the acceptable site list.  The block can be overridden by a parent or administrator; Kidsnet users seeking access to a blocked site which they believe should be on the okay list can also submit a site for review and if it is approved will be added to the approved list, generally within 24 hours.
* Software using this technique: Kidsnet
* Best suited for: Young Children (11 and younger)

Black List Filtering
- This method finds objectionable sites and adds it to a list. All sites on the list are blocked. The block can be overridden by a parent or administrator; sites can be submitted to the list keeper for sites to either be added or removed.
* Software using this technique: S4F Filterpak, Weblocker
* Best suited for: Older Children and Adults (12 and over)

Keyword Filtering - This method uses a list of forbidden words such as "XXX" and blocks any page or site that contains the word.  Often is the cause of sites being wrongfully blocked; for instance in the above case a site about "Superbowl XXX" would be blocked.
* Software using this technique: Weblocker, CyberSentinel
* Best suited for: Situations where blocking by category (illegal, drugs, etc.) is not a concern.

Heuristic Analysis & Keyword Filtering - This method uses a combination of a black list of  pre-programmed phrases, words combined with programming that quickly analyzes the website seeking  known design techniques used by adult site operators to identify adult oriented content. Very effective against adult sites because such techniques are almost always used so the site can be found in search engines
* Software using this technique: CyberSentinel
* Best suited for: Situations where primary concerns are adult sites and chatting with  cyberpredators. (Such chats are also blocked.)
