The Security Intelligence Service has begun offering people a confidential website to provide information on issues of national security.
Since 2001, the SIS has relied on an 0800 number for tip-offs from the public.
SIS director Warren Tucker, says the online service is a way of using the latest technology to access information from willing members of the public.
The website says it is monitored 24/7 and any information provided will be treated confidentially.
