I haven't used it, and can't speak to it being "top notch", but they're advertising it as a fully fledged endpoint product that even includes some things like FIM (File integrity Monitoring), which are usually only available as expensive add-ons or additional modules with traditional security products like McAfee.

If it were me, I would compare and contrast it's features and support with commercial offerings and see which one you feel the most comfortable with. There's a lot at stake when it comes to security. It's probably best not to let your decisions be 100% about up-front cost.
