Smaller businesses should also use the National Cyber Security Centre’s (NCSC) Cyber Action Toolkit.

Follow NCSC advice and sign up to their Early Warning Service. The NCSC provides free, practical advice, training and guidance at ncsc.gov.uk for organisations of every size. Early Warning is a free service from NCSC, which can inform organisations of potential cyber attacks and give them invaluable time to act before an incident escalates.
