Security features of RFX process

Hi Gurus,

We are in the process of evaluating SRM RFX process for sourcing. We have an apprehension about the security features of SRM and would like to know more about it. Is there any possibility of data leakage/security lapse to our network when SAP is exposed to vendors through web (link).

Please throw some light on the security features SAP SRM .

Regards,

AMV
