Embodiments disclosed herein provide a control logic that can identify and track social identities of users belonging to a private network. The control logic may be implemented as a middleware communicatively connected to network user devices and to social networking platforms. The middleware can programmatically identify and extract particular pieces of information from requests and/or responses monitored at a network proxy server and correlate the extracted pieces of information to identify social identities across social networking platforms. The correlated information for each identified social identity may be stored in an identity database as a cohesive user identity record. Information stored in the identity database can be used to consistently apply and enforce policies that are applicable to individual users in the private network.
