The central and secure management for your IoT device identities

Establish trust for your IoT devices: With Device Attestation as a Service, you can assign trusted authentication identities to your IoT devices via crypto-graphic key injection. Once identities have been assigned to the devices, it is possible to detect and prevent the utilization of counterfeit components and eliminate fraudulent warranty claims since you can easily verify the authenticity of the devices.

In addition, you can include device attestation in your audit processes, helping you to keep a real-time log of the status of your devices – provable at any point in time. 

Easily book the service in the Trust as a Service portal and generate cryptographic keys for your connected devices. You always have access to the complete list of keys with the possibilities to import, export and manage them. This allows you to activate end devices, verify their authenticity and withdraw identities. 

The Trust-as-a-Service portal is the central administration portal for managing your cryptographic inventory and devices at a glance. It is remotely accessible and always available, reducing capital expenditures and maintenance. 

There is no need to manage physical resources or worry about availability or compliance. Still, all cryptographic keys are securely stored in a FIPS 140-2 validated hardware platform – available to you via the Trust as a Service portal.
