Hello,
You are running the Version of SEP 11.x
Just to Let you know that Proactive Threat Protection is currently not supported with a Server or 64-bit OS.
Are these machine 64 bit machines / servers?
In case if these are 64 bit machines, you may like to check this Document -
Symantec Endpoint Protection 11.0 compatibility with 64-bit platform
http://www.symantec.com/docs/TECH102143
and incase of Servers, then the Proactive Threat Protection would show itself as "OFF", check this Article:
Proactive Threat Protection status shows "OFF" in the client interface
http://www.symantec.com/docs/TECH104987
Now, in reference to the "Security Status - Attention Needed", could you let us know what do you see under the Attention reports?
