Over the last 12 months, the NCSC has played a key role in managing significant events and taken action to make the UK a safer place to live and work online. A particular highlight has been the work that the NCSC did to support the Covid-19 vaccine roll out. The NCSC dealt with 777 incidents – an increase on last year – of which 20% were linked to the health sector and vaccines. One of the trends the NCSC has seen over the last year was a worrying growth in criminal groups using ransomware to extort organisations. It is now the most immediate cyber security threat to UK businesses and one which should be higher on the boardroom agenda.
