A social network (SNET) is divided into one or more circles having different trust levels. Communications between the different SNET circles is bridged by an SNET device capable of communicating with devices associated with the different SNET circles, even if those devices cannot communicate directly with each other. When a communication is sent between SNET circles, the SNET device verifies the trust level associated with the communication, and bridges the communication based, at least in part, on that trust level. The SNET device can be located in a demilitarized zone associated with both the first SNET circle and the second SNET circle. Where different SNET circles use different security secrets for communications between members, the SNET device can store different keys for each of those circles in separate, restricted portions of memory.
