The colorscheme is okay but the logo design is a bit too plain. Try adding a nice gloss effect to it or use a more unique font. @Brennan: header looks fine on FF (on a mac) for me
IMO, its fine and user must find white space also in a page otherwise it looks clutter and this looks good. You can put a home page link on AlertSwift logo on all the pages and give a title attribute to this logo "website monitoring service".
