As the number of IoT devices and connected devices continues to surge, IoT security has become a critical component of the modern IoT ecosystem. Ensuring the confidentiality, integrity, and availability of data across IoT networks is essential to protect against cyber threats and data breaches. With billions of devices now connected to the internet, the attack surface for malicious actors has expanded dramatically, making robust security measures more important than ever.

Microsoft Azure IoT provides a comprehensive platform for IoT development and deployment, but organizations implementing large-scale production deployments often encounter limitations in Azure’s native security and identity management capabilities that require additional solutions to address enterprise requirements. Device Identity Management Limitations in Azure IoT Hub center around the platform’s reliance on symmetric keys or self-signed certificates for device authentication.

Machine identity lifecycle management has evolved beyond a technical implementation challenge to become a fundamental component of enterprise risk management and digital transformation strategy. As a core element of a modern cybersecurity strategy, machine identity management ensures that organizations can effectively protect their digital assets and adapt to evolving threats.

IoT security has become a top priority in today’s hyper-connected world, where billions of devices—from sensors and cameras to industrial controllers—are linked across diverse networks. As organizations deploy more IoT devices to drive innovation and efficiency, they also introduce new security challenges that traditional security models are ill-equipped to address.

Traditional Public Key Infrastructure represents the established approach to certificate management that has evolved over three decades to support enterprise IT environments. Built on hierarchical certificate authorities (CAs) and manual or semi-automated processes, traditional PKI was designed for relatively static environments with manageable numbers of certificates and predictable lifecycle patterns.

Everybody loves a good throwback. Flip phones, vinyl records, and maybe even the dial-up tone for nostalgia’s sake. But if your operational technology (OT) and industrial internet of things (IIoT) environment is still relying on traditional VPNs to connect users, vendors, and machines, that’s one throwback you really don’t want. OT systems have evolved. They’re smarter, more connected, and unfortunately more vulnerable than ever.

It’s been nearly three years since UNECE WP.29 regulations came into force for new vehicle types in Europe, and the global ripple effect is in full motion. WP.29 laid the groundwork for how cybersecurity is handled across the automotive lifecycle – from design and development through post-production and updates. But what’s happening beyond Europe?

Industrial IoT (IIoT) networks are under siege—from ransomware attacks that halt production lines to nation-state actors targeting critical infrastructure. Yet, traditional security measures struggle to keep up with these stealthy and persistent threats. This lack of visibility and proactive detection leaves security teams blind to lateral movement and insider threats lurking within OT environments.

As organizations increasingly rely on connected devices to drive efficiency and innovation, the Extended Internet of Things (XIoT) — covering industrial control systems (ICS), operational technology (OT), Internet of Things (IoT), and Internet of Medical Things (IoMT) — has rapidly expanded. This greater connectivity often drives increased vulnerability as critical assets are exposed to sophisticated threats.

In a significant shift for digital identity management, the maximum lifespan of public TLS certificates is set to be reduced to just 47 days, following a new policy from Apple’s Root Program. With Google expected to follow suit, the clock is ticking faster than ever on certificate validity and that has profound implications for businesses relying on manual processes.
