The cyber risks facing the United Kingdom are being “widely underestimated,” the country’s new cyber chief will warn on Tuesday as he launches the National Cyber Security Centre’s (NCSC) annual review. From a report: In his first major speech since joining the NCSC — part of the signals and cyber intelligence agency GCHQ — Richard Horne will drive a shift in tone in how the cybersecurity agency communicates these risks. Despite some evidence showing cyberattacks growing year-on-year for half a decade, the NCSC has not previously confirmed the trend nor expressed alarm about it.

“What has struck me more forcefully than anything else since taking the helm at the NCSC is the clearly widening gap between the exposure and threat we face, and the defences that are in place to protect us,” Horne will say, according to an advance preview of his speech on Tuesday. Citing the intelligence that NCSC has access to as an agency within GCHQ, Horne will warn that “hostile activity in UK cyberspace has increased in frequency, sophistication and intensity,” adding that despite growing activity from Russian and Chinese threat actors, the agency believes British society as a whole is failing to appreciate the severity of the risk. The annual review reveals that the agency’s incident management team handled a record number of cyber incidents over the past 12 months — 430 compared to 371 last year — 89 of which were considered nationally significant incidents.
