Flexible, Scalable, Trusted for IoT Platforms, and Connected Devices

By 2020, an estimated 25 billion devices will be connected to the Internet of Things. As these devices become more integrated in our everyday lives, they require innovative security solutions to protect end users from eavesdropping or malicious attacks.

Correctly implemented, PKI can build and support security and trust in IoT ecosystems and connected devices. PKI’s role in IoT provides strong identity authentication and creates the foundation of trust that systems, devices, applications, and users need to safely interact and exchange sensitive data.

The Complete IoT Security Solution


Identity & Authentication

DigiCert IoT solutions deliver the critical authentication of users, systems, and devices without the need for tokens, password policies, or other user-initiated factors ensuring connections with trusted users and devices.


DigiCert SSL encryption inherently delivers the essential elements of privacy. SSL certificates can be used to encrypt data in motion and secure information being communicated between systems and devices.

Data & System Integrity

DigiCert signing services maintain that software, firmware, drivers, data, or configuration settings have not been altered or tampered with, ensuring greater control over intellectual property.

Why Use PKI for the IoT?

PKI is the trusted security solution for protecting system, consumer, and patient devices and personal data.

PKI Is Secure

PKI provides the highest level of authentication and encryption to ensure data integrity for IoT devices.

PKI Is Scalable

PKI systems provide the components required to manage the provisioning and management process of device certificates and keys throughout a device’s lifecycle.

PKI Is Flexible

PKI security allows for a variety of deployment approaches and this makes PKI the most flexible solution for securing IoT devices.

PKI Is Trusted

PKI’s existing infrastructure of identity vetting completed by publicly trusted and audited Certificate Authorities provides the necessary foundation for IoT organization authentication.

Scalable, Custom Solutions for All Industries

DigiCert's PKI for IoT systems and devices meets the needs of projects of all industries and sizes. Leveraging our industry-leading certificate management platform and robust, scalable deployment systems and APIs, DigiCert brings end-to-end security and management for the Internet of Things.

Smart Technology

IoT PKI enables enterprises to securely use technological advancements for business automation. Many enterprises today are finding that PKI meets the IoT demands for security, scalability, and flexibility.

Smart Home & Wearables

PKI secures the devices and systems we rely on for everyday conveniences, such as home automation systems, smart devices, and connected wearable devices. These devices undoubtedly are changing how we live; security solutions are greatly needed for peace of mind and trust.

Smart Industry

Smart cities, smart grids, smart automobiles, and smart industries need to be built with strong security. IoT PKI ensures secure deployments from the initial stages of infrastructure and product development to production stage of projects.

Smart Medical

Networked medical devices and health information systems need to be secured in order to protect sensitive patient data. IoT PKI ensures privacy, and protects health information systems and PHI on networked devices.
