Secure IoT with PKI-based identities

For any IoT application, it is crucial to protect data, user privacy, and safety. Breaches can harm production continuity and business processes, customers’ trust, and – worst of all – human health and life.

To enable true end-to-end security and prevent cyber attacks against IoT applications, a public-key infrastructure (PKI) can be used to issue certificate-based identities. These trusted identities secure the IoT applications with strong authentication of devices, people and servers, encrypted communication and proven data integrity.


 IoT for multiple business verticals

Issue and manage certificate-based, cryptographically secure and unforgeable identities for IoT devices and applications, enabling end-to-end security within the following sectors:

Trusted identities for IoT as a service

Subscribing to a service for PKI certificate lifecycle management for your IoT application means that you can focus on your core business, let experts manage your IoT device trusted identities from a compliant and certified data center, and pay as you grow.

Nexus GO IoT

Nexus GO IoT is a PKI certificate lifecycle management cloud service for IoT applications based on the Nexus Smart ID IoT product. It is a compliant, scalable and highly available service offering comprehensive functionality that is used and appreciated by many customers in different industries worldwide.

Nexus Identities for IoT

Protect communication between things

Nexus helps you to protect all types of smart devices, so that you can secure their communication and avoid hijacking.


How does it work?

The Smart ID PKI platform issues certificate-based, cryptographically secure and unforgeable identities that enable:

Strong authentication: Certificate-based authentication ensures that only authorized users, devices or servers can connect to a network or application. Revocation of certificates instantly blocks access in case of compromise or emergency.

Encryption and Privacy: Certificates enable encrypted communication between devices and services for secure transmission of data over TLS.

Integrity: Digitally signed messages based on certificates can be used to prove the origin of data, and to detect manipulation of data. Signed firmware enables secure software updates.
