something like Secunia PSI for Mac?

Hi folks

Is there something like Secunia PSI for mac?

+The Secunia PSI allows to scan, detect, check, and secure the applications installed on a computer. It also helps to secure applications, and to quickly and easily upgrade to new and secure versions of applications installed on a computer.+

I found only AppFresh -> http://metaquark.de/appfresh. Its quite buggy.
