X3 Watch - Free
“This free version of X3Watch gets you the basics. It records the possible objectionable sites with the date and time they were visited. Reports only go to the chosen accountability partners and information is not stored or used by XXXchurch or any other organization.”
Very basic protection. Mac version runs as the root user, uses your administrator password, and does not offer an option to use a separate password, so your administrator always has the ability to turn it off, although your partners are notified of changes. It is not ideal for anyone who needs to have administrator privileges for other reasons, but is also tempted to uninstall or disable the software. Also, its sensitivity to questionable material is a bit dull -- it doesn’t always recognize things that are mildly inappropriate.
X3 watch is very unobtrusive. It is easy to install and uninstall, it just requires the root password. Many of the other software solutions block things they shouldn’t, and always remind you that they are watching you. Depending on your computer usage this could be good or bad.
The upgraded version ($20) offers Myspace monitoring, 3 accountability partners, tech support, weekly or bi-weekly reports, multi-user options, full detailed reports, and built in help.
Conclusion: This is the software that I use personally for lack of anything better. It doesn't do a lot of the things I would want (more sensitive reporting, adjustable web blocking), but it uses very little resources and doesn't get in my way, which is perfect for me because I have such a diverse use of my computer for my IT work, and I cannot be slowed down because some software incorrectly blocks websites I need to go to.
