UK DSIT Secures Half Million Domains Amid Rising Threats

The UK's Department of Science, Innovation and Technology (DSIT) is responsible for securing over half a million domains across various government organizations, including the National Health Service (NHS). At Infosecurity Europe 2026, Nick Woodcraft from DSIT discussed the challenges of advising these organizations on cybersecurity vulnerabilities, emphasizing the need to communicate in straightforward terms.

DSIT simplifies discussions around issues like DNS vulnerabilities by focusing on potential outcomes rather than technical details. Additionally, DSIT employs technology such as Security Information and Event Management (SIEM) solutions to enhance vulnerability management. They advocate for a staged approach to information sharing to prevent overwhelming organizations. Moving forward, DSIT aims to ensure that organizations perform fundamental cybersecurity practices to mitigate new vulnerabilities.
