Today, the Guardian, in collaboration with the University of Cambridge, launches Secure Messaging, a world-first from a media organisation

T

oday, the Guardian launches a unique new tool for protecting journalistic sources. Secure Messaging is an important new technological innovation that will make it easier for people to share confidential information with us.

Blowing the whistle on wrongdoing has always taken bravery. As threats to journalists around the world increase, so does the need to protect confidential sources. One of the most dramatic global shifts against whistleblower safety comes as part of the Trump administration’s continued assault on the free press.

Investigative reporting is extremely important to the Guardian; we have been exposing wrongdoing and scrutinising power with complete independence for decades. We know first-hand how impactful investigations depend on trusted reader-reporter interactions. From the Frank Hester revelations to the Pegasus project, Uber files, Pandora papers and the Michelle Mone/PPE Medpro scandal, many of our most powerful recent investigative projects – as well as our biggest stories throughout the decades – have relied on sources feeling confident they can safely share information with the Guardian or our reporting partners. Secure Messaging is the latest tool in our armoury to protect whistleblowers.
