An overview of how SIR Certification provides a structured, tiered assurance framework for assessing the security and resilience of industrial radio communications used within operational technology environments.

When discussing cybersecurity and industrial radio systems, a common question arises: “Doesn’t the Radio Equipment Directive (RED) already cover this?” The answer is more nuanced than a simple yes or no. What RED addresses The Radio Equipment Directive establishes essential requirements that radio equipment must meet before being placed on the market. Recent delegated acts under RED have expanded its scope to include certain cybersecurity considerations. These provisions focu

As part of ongoing engagement on the security of industrial radio communications, the Secure Industrial Radio (SIR) Certification framework has been formally shared with the UK’s National Protective Security Authority (NPSA) for awareness and consideration. This submission formed part of broader information-sharing on the use of radio communications within operational technology (OT) environments and the potential risks associated with legacy deployments. Context for the subm

When cyber threats are discussed, attention often focuses on internet-connected systems: firewalls, exposed services, phishing attacks, and network intrusions. However, across the UK and internationally, many essential services — including water, energy, transport, and industrial operations — continue to rely on radio communications that were not originally designed with modern cybersecurity threats in mind . In some cases, these radio systems carry control commands and telem
