Fortified Auth. Logo

This is a submission to a 99designs.com logo contest (no, I didn't win :/ )

The client wanted a logo for their home security company. That inspired me to think about how a "man's home is his castle"; so I combined a home with a castle tower. I believe it sends a visual message of security (blue plays a role here) and the overall shape resembles a badge or shield.

Let me know what you think!
Good day.
