EN 301 549 is the European technical standard for accessibility in information and communication technology (ICT) products and services. It defines measurable requirements for things like websites, mobile apps, software, hardware, documents, and support services so organizations can test whether digital systems work with assistive technologies such as screen readers, voice control, and keyboard navigation.
In cyber security and digital assurance, EN 301 549 matters because accessibility cannot be verified by confidence or appearance alone. Teams need objective criteria for procurement, compliance, and quality control, especially when AI systems route users to services or interfaces. If metadata is stale, a page is unreadable, or an app breaks at the handoff point, the result is both an accessibility failure and an operational risk. EN 301 549 gives defenders a concrete baseline for validation, audits, and continuous testing.
