As mentioned in my previous posts, outsourcing security is not a sign of desperation. There are many companies which outsources different security functions.

If you want to know what top security functions are commonly outsourced, I bring you the list. The list was derived from the results of the survey done by Information Week/Accenture Global Information Security.

Top Security Functions:
Managed Firewall - 29%
Managed Intrusion Detection - 25%
Vulnerability Assessment - 21%
Messaging Protection - 18%
Computer incident and response - 17%
Disaster Recovery Management - 17%
Security Strategy - 15%
Vulnerability management - 15%
Security governance - 11%
Asset and configuration management - 11%
End device security - 11%

I'm sure that from this list, you would have an idea of your own outsourced security functions.
