Having joined Keytos well over a year ago now (time flies?), I’ve observed a significant uptick in the demand for, and conversations around, secure PKI solutions for IoT Devices. The growing awareness and need for enhanced security measures have been palpable, and it’s clear that scalability, security, and ease of management stand out as the most important characteristics of a “good” PKI as far as the IoT manufacturers are concerned. In reality, these factors are not just technical requirements; they’re essential for maintaining trust in IoT ecosystems and supporting their expansive growth. Our PKI for IoT, EZCA not only facilitates secure, certificate-based authentication of IoT devices but also leverages the power and scalability of your existing Azure resources, ultimately saving you time and money. Check out the video below and read more about how to get started with the best PKI for IoT in 2024.
Azure IoT Hub Integration: After Intune, the biggest use for certificates in Azure is Azure IoT Hub. IoT Hub is a managed service, hosted in the cloud, and acts as a central message hub for bidirectional communication between IoT applications and the devices it manages. From the perspective of an IoT security engineer, ensuring that your PKI connects to Azure IoT Hub is crucial because it enables secure device authentication, ensures encrypted communication, and facilitates the management of digital certificates for devices, thereby significantly reducing the risk of unauthorized access and data breaches in IoT ecosystems. This integration not only enhances the security posture of the IoT solution but also streamlines the management of device identities and encryption keys, which are essential for maintaining the integrity and confidentiality of the data being transmitted.

Scalability: Active Directory Certificate Services simply wasn’t built to accommodate the magnitude of certificates we’re dealing with in our modern operating environment. A Scalable PKI is vital due to the exponential growth in the number of IoT devices, each requiring unique digital certificates for secure authentication and encrypted communication. The sheer volume of certificates necessitates a robust, scalable PKI to efficiently manage and authenticate potentially millions of device identities. This capability ensures that as the IoT ecosystem expands, the security infrastructure can adapt without compromising the speed, efficiency, or reliability of device authentication processes, thus maintaining a secure and trustworthy environment for IoT operations.
Cloud-Native: Designed to leverage the scalability, flexibility, and resilience of cloud environments, enabling them to seamlessly manage the vast number of certificates required for IoT devices. This means they can dynamically scale to meet demand without the manual intervention required by legacy systems. Second, cloud-native PKIs are built with modern security protocols and integrations in mind, ensuring that they can provide more robust security features and compliance with current standards. Lastly, we offer improved operational efficiency and reduced complexity, as we’re designed to integrate seamlessly with other cloud-native services, allowing for more automated and efficient certificate lifecycle management. This modern approach significantly reduces the risk of misconfigurations and vulnerabilities that could be exploited in a less cohesive, retrofitted system
IoT-Focused PKI: In the intricate ecosystem of Azure, where corporations of immense scale coexist with nimble startups, EZCA has established itself as the preferred Azure Certificate Authority for IoT, primarily due to its deep integrations with Azure’s infrastructure. This integration facilitates an uncomplicated and efficient pathway for entities to architect their Public Key Infrastructure as a Service (PKIaaS) within Azure, emphasizing a “set it and forget it” philosophy. EZCA assumes the mantle of responsibility for all facets of certificate management operations, ensuring a seamless and uninterrupted service.
We understand the unique challenges and requirements of securing a vast, diverse array of IoT devices, including the need for automated certificate rotation and efficient lifecycle management. These tailored features are critical for maintaining the security integrity of devices throughout their operational life, accommodating scenarios like frequent updates, varying connectivity, and constrained resources.
What propels EZCA into prominence within the IoT domain is not just its utility but also the comprehensive suite of resources it provides. From exhaustive guides that escort users through the intricacies of certificate creation for Azure IoT—encompassing best security practices and detailed walkthroughs for implementing certificate authentication in Azure IoT Hub—to the provision of user-friendly code samples/APIs and a NuGet package designed to simplify the certificate issuance and management process, EZCA has meticulously crafted a service that is as accessible as it is effective. This strategic combination of integration, education, and tooling makes EZCA an indispensable ally for any organization venturing into the IoT landscape with Azure.
