External contact connections to authenticate and contextualize entity

A high percentage of received communications are from external entities. In response to receiving a communication from a sender associated with an entity, the entity may be authenticated and contextualized by retrieving and processing contact information for people at the entity that are directly and/or indirectly associated with a recipient of the communication. For example, contact information for people at the entity who have previously communicated with and/or are connected to the recipient or users related to the recipient, for example, may be retrieved from one or more directory services, social networks, and/or professional networks. The contact information may be processed to create corresponding contact objects, and the contact objects may be processed to create an entity object for the entity that comprises one or more connections between the recipient and the people at the entity. The entity object may be provided to the recipient for display.
