The Cyber Conference in the capital closed with a call for the industry to continue its dialogue with the government to ensure defences against hackers and state-backed attacks remain robust.
This week has seen the Foreign Secretary William Hague leading a conference that has heard from governments and law enforcement agencies about the current risks and the best ways to defend against them.
The main aim of the event was to produce the London Agenda, which would collect the ideas and suggestions made at the conference and pull them together into something that would lead the debate in the future.
Closing the conference Hague held out an invitation to those in the industry to continue to shape the future discussion.
"The message to individuals is: this is your debate; you must be our allies in ensuring that the future global consideration of cyberspace remains true to its own nature and allows for a vast diversity of opinion and individual expression," he said.
