Robert Hannigan, who recently took over as director of the UK's Government Communications Headquarters (GCHQ) - also referred to as Britain's listening post - warned that some US tech companies are "in denial" about how their services are being misused.
"However much they may dislike it, [US technology companies] have become the command and control networks of choice for terrorists and criminals, who find their services as transformational as the rest of us," he writes in an article for 'The Financial Times' today.
In his first public intervention, Hannigan argues that the big internet firms must work more closely with the intelligence services, warning that "privacy has never been an absolute right".
He goes on to say that Islamic State (IS), also known as ISIL, has a different approach to using the internet than other extremist groups have had.

The debate about whether security agencies should be allowed to access personal data through social-networking sites like Google and Facebook was brought to the fore in 2013 after Edward Snowden leaked details of alleged internet and phone surveillance by US intelligence.
Snowden, who has been granted temporary asylum in Russia, faces espionage charges over his actions.
Hannigan, who has advised the British Prime Minister on counter-terrorism strategies in the past, calls for a "new deal" between democratic governments and the technology companies in the area of protecting citizens.
