Where to get recognizable, 3rd party security audits?

[Pigeon <fredit () charter net>]

Hello, I need to find a company that will do security testing on our  
5 or 6 servers to verify their security level. We will need a very  
well recognized certificate from them.. AKA, I couldn't do the  
security audit, and no Joe Blow (granted you might be awesome) can do  
them. The reason for this is to show VERY large corporations our  
credentials.


So far, people have mentioned these certs:
SAS type 2
FISAAA
HIPPA
ISO7799
COSO


but I am unsure on these.. It appears like these could takes months  
to prepare internally and then we submit the information to an  
organization for review. Is this normal?


thanks!
