As a result, data is exposed in clear to the broker server, which typically runs on a third-party infrastructure. This leaves private and business-critical information exposed to collection and tampering.
E4 solves this problem thanks to a unique combination of client software and key management server suitable to all MQTT deployments, with minimal performance overhead (no extra RTT, at most 24 bytes per packet).
E4 can also be adapted to other protocols than MQTT. We can work with you to adapt E4 to your bespoke needs.
