E4: Security Designed for IoT

Highest security. Data's secrecy and integrity is protected from its producer to its consumers, different keys are used for different type of data and can be changed at any time.

Dynamic key server. A major pain when deploying encryption at scale is key management. We solve it thanks to a simple interface to manage and distribute keys in an automated fashion.

Maximize performance. E4 is faster and smaller than any competing solution. We minimize resources usage and integration costs thanks to meticulous design choices.

Meet compliance and data control standards. Use any cloud or third-party servers without having to worry about data security, since your data is protected end-to-end.

Optimized for MQTT. Our solution is compatible with the IoT platforms of AWS, Azure, Google, and IBM, and works with many other protocols (Kafka, AMQP, RabbitMQ, etc.).

Plans

E4's client library is offered for free to protect data with a static key, and in order to test its integration in your devices with minimal effort.

Our dynamic key server allows you to manage devices' keys remotely manually or using automation rules. It is offered on-premise or as a managed service, and billed per-device on a subscription basis, starting at $0.10 monthly.
