There were 188 cyber attacks classed by the NCSC as Category Two or Three during the last three months.
And even though the UK has not experienced a Category One attack - the highest level, an example of which would have been the theft of confidential details of millions of Americans from the Office of Personnel Management - there is no air of complacency at the NCSC's new headquarters.
Ciaran Martin, the centre's chief executive, told the BBC: "We have had significant losses of personal data, significant intrusions by hostile state actors, significant reconnaissance against critical national infrastructure - and our job is to make sure we deal with it in the most effective way possible."
