Foreign Secretary Wee Willie Hague is hosting a cybersecurity conference later this year.
The two-day event will be held on 1 and 2 November and more than 80 organisations have been invited to attend.
Hague said international cooperation was vital to ensure that cyberspace "remains a safe and trusted environment in which to operate."
Chatham House and the International Chamber of Commerce will work with the FCO to arrange the shindig.
Hague used a speech in February to announce the coming conference, but not its date.
He cited Google and Twitter for their supposed role in north African revolutions.
But Hague also warned of increasing dangers. He said emails with ZeuS malware were sent to the UK government and "a large number of emails bypassed some of our filters". He also mentioned a targeted email attack sent to a defence contractor apparently from another contractor.
Hague is hoping for some sort of international agreement on the best way to counter security and crime threats online.
