Can anyone tell me, Can Symantec Messaging gateway used as Email DLP. I had seen somewhere to use it for Email DLP. What is advantages and limitation of this. What kind of support we can get from Symantec.

Symantec SMG and DLp can be integrated, some of the helpful links

How Symantec Messaging Gateway and Data Loss Prevention Network Prevent interact

Integrating Symantec Data Loss Prevention Enforce Server and Symantec Messaging Gateway

Symantec Message Gateway (SMG) in my mind can be thought of a DLP "light" version compared to the full DLP suite.

While Pete is correct the SMG can be integrated to work together there are some features of DLP within the product.  For example SMG can block emails based on keywords and patterns (think of this as Described Content Matching) however SMG cannot deal with the advanced detection capabilites that DLP can (EDM, IDM, VML).

So in one of my enviornments if I send an email w/ a keyword in it, the message gets blocked by SMG, while in another environment I have the full DLP suite doing deeper content inspection.

I hope this makes sense.

You can usse SMG as Email DLP but still it is not effective tool to monitor and protect confidenatil data also you need Web DLP so at some extent you will get some result but u can't expect more from this tool, below some points can be considered,

• SMG not provides actual information or files on which confidential information detected, it just captures whole attached file as forensics.
• SMG not allows to set the no. of matches and occurrences to generate incidents this result in increase in false positive incident which may have low or zero severity.
• SMG cant provides the flexible search criteria/ parameter for details search,  it just provided sender, recipient message ID, subject etc.
• Auto escalation feature is not present in SMG 
• No customized access control to protect incident contents, policy, etc. 
• SMG can’t provide to add any note on any incidents for future reference of incident Mgr.
• SMG can’t correlate any past violated incidents with new which will not allow us to understand the trend, count and incident type details for future improvements
