Endpoint Protection

I'm considering whether to turn this on or off in our new environment.  I've read the info here:

http://www.symantec.com/connect/articles/submitting-information-about-detections-symantec-security-response

Can someone tell me a little more about how enabling these settings would benefit the security of our company?  Also, how much data would be uploaded through our network?  Does the data go from our client to the SEPM and then out to Symantec, or does it go directly from the client to Symantec?

They benefit Symantec and the entire customer base. Symantec may be able to get out signatures for better detection.

If you enable on the client, it goes right out to Symantec. The data being sent out is fairly small. But it also depends on how many clients you have. thousands of clients and it could add up.
