COMPLIANCE AND DATA CONTROL. Use any cloud or third-party servers without having to worry about data security, since your data is protected end-to-end.
E4's client library is offered for free to protect data with unmanaged keys, 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.
E4 supports both "many-to-one" and "many-to-many" IoT architectures, and is suitable for various applications such as automotive, smart city/building, healthcare, or access control.
Examples of applications of E4 include:
SECURE UPDATES. Remotely provision new software or configurations without risks of replay of sabotage.
PRIVACY-PRESERVING APPLICATIONS. Personally identifiable information or other privacy-sensitive data is protected against eavesdropping and surveillance.
ENCRYPTED REMOTE STORAGE. Access and copy sensitive data in large filesystems or databases from any IoT device, for secure sharing, back-up, or just work around IoT platforms' limited memory.
ON-PREM TO CLOUD TRANSITION. Migrating to a cloud model and need to keep full data control, for privacy or regulatory compliance? E4 helps you get the best of both models.
