Time-saver alert: Rather than list the hundreds of certification sites that exist under the sun (and yes, even Sun has a certification site), and then have you sort through them, we did it for you. We cherry-picked only those sites that offered a breadth and depth of information for a number of technology certifications. There are tons of great Microsoft-only sites, for example, but those arent highlighted here (you can find those specific links under our Editors Picks/Skills development on each of our TechTarget.com search sites).

Here are the top 10 IT certification sites that we judged will offer you rich content -- useful resources and links, discussion forums, articles and current information -- in a variety of areas.
