I'll give you feedback since you ask.

- Up the font size on your blog, I can't read it without zooming in considerably.

- Try to actually explain, giving examples help, what the different security parts do rather than quickly explaining, this blog post feels as if it were written up in 15 minutes to sell your product rather than being informative

- Don't be afraid to use markup other than anchor and paragraph tags, for this article using subheadings for the 3 types of security would make the article easier to follow (remember people love to skim).
