About a month ago, I saw Justin of Dragon Blogger talking on Facebook about a new service he was using called Incapsula. I decided to sign up (it's free) and give Incapsula a try. The best way to visualize Incapsula is to think of it as the "middle man". Incapsula sits between your server and your reader, so instead of your user's computer asking your server to deliver your blog's pages directly, it asks Incapsula and then Incapsula talks to your server. In addition to protecting your server, Incapsula also gets rid of some of the server load.
