What’s it all about?
For the unfamiliar, Early Warning is a threat-notification service from the NCSC that informs your organisation about potentially suspicious activity on your network. It does this by filtering the millions of events the NCSC receives every day, and then correlates them with the IPs and domain(s) you provide at sign-up, via notifications.
You might wonder what’s special about Early Warning when there are plenty of other data feeds out there. Well, the service uses information feeds from the NCSC, as well as trusted public, commercial and closed sources, including several privileged feeds not available elsewhere. What’s more, this service is free of charge for UK organisations.
There is already a huge community of organisations using Early Warning and feedback has been really positive – a recent survey of organisations using it found that a considerable majority agreed or strongly agreed that Early Warning was important to their organisation and provided reliable data.
