Whistleblowers – insiders who expose corrupt or illegal activities – are an important source of information for journalists everywhere. From their position inside governments, companies, and other organizations, they can provide crucial leads, evidence, and sometimes “smoking guns” that expose everything from fraud and waste to criminal conspiracies and war crimes.

It’s important for journalists to identify the motives of whistleblowers and to verify their information. Equally essential is knowing how to best protect them as sources. Fortunately, there’s a wealth of information fon whistleblowing, including a growing number of NGOs with expertise around the world.

To help journalists to navigate this challenging terrain, GIJN has created the following list of resources. If you think a group or resource should be included, write us at .

Whistleblowing is an act of a man or woman who, believing in the public interest, overrides the interest of the organization he / she serves to publicly blow the whistle if the organization is involved in corrupt, illegal, fraudulent, or harmful activity.
— Ralph Nader, consumer advocate and activist

Guidance from Experts

If whistleblowers are willing to provide you with information, they should be treated with special care.

GIJN has summarized guidance on working with whistleblowers from a variety of sources. The reports include much more detail and deserve a full read.

The Perugia Principles for Journalists, subtitled “Working with Whistleblowers in the Digital Age.” It was published in in 2019, and written by Julie Posetti, Dr. Suelette Dreyfus, and Naomi Colvin. The Perugia Principles were developed by the authors in partnership with a round table of 20 international journalists and experts hosted by Blueprint for Free Speech in Perugia, Italy, in April 2018. The authors then consulted with the broader investigative journalism, legal, and academic communities to refine 12 principles:

    1. First, protect your sources. Defend anonymity when it is requested.
    2. Provide safe ways for sources to make ‘first contact’ with you, where possible.
    3. Recognize the costs of whistleblowing for the whistleblower, and prompt them to think through ahead of time how to cope when the story breaks.
    4. Verify material focusing on the public interest value of the information, not on your view of the attitudes or opinions of the source or whistleblower.
    5. Take responsibility for your digital defense and use encryption. Even though encryption may not completely defend your source, it offers important first-line protection.
    6. Determine the biggest threats to you and your source, and what specific steps you need to take to protect both of you.
    7. Explain the risks of digital exposure to your source or whistleblower. On sensitive stories, train your whistleblowers in basic digital security.
    8. Publish original documents and datasets in their entirety where possible and safe to do so, recognizing the importance of datasets in stories.
    9. Securely delete data provided by sources, when asked, to protect confidential sources, consistent with ethical, legal, and employer obligations.
    10. Ensure any digital drop boxes for confidential sources and whistleblowers offer a good level of security, and, for higher-risk materials, anonymity.
    11. Understand the country, regional, and international legal and regulatory frameworks for protecting confidential sources and whistleblowers.
    12. Encourage news publishers to practice their responsibility to provide proper data security for journalists, sources, and stored materials, along with appropriate training and policies to guide journalists.

The report elaborates on these principles. It has been published in Russian, Greek, Spanish, and German.

10 Tips for Journalists Working with Whistleblowers. This 2019 article by Rowan Philp summarizes the messages of presenters at the GIJC 2019 conference in Hamburg, Germany.

Working with Whistleblowers: A Guide for Journalists was created by two US organizations: the Government Accountability Project (GAP), a leading whistleblower protection nonprofit, and the Society of Professional Journalists. It was published in 2017. “We hope to help journalists have whistleblowers’ backs, rather than unwittingly exposing them to further retaliation,” the 36-page guide’s forward states. It includes the following advice:

    • Because the risk of reprisal for whistleblowers is high and the legal landscape is complex, both journalists and sources would be well-served to consult or coordinate with GAP or other lawyers versed in whistleblower law before acting on information supplied by an employee source.
    • Journalists who work with intelligence whistleblowers should realize that any story based on classified information may result in the whistleblower’s prosecution.
    • Journalists should not insert themselves into stories; you’re not there to be a strategist or offer PR advice, nor can you be the whistleblower’s lawyer. But by developing trust and demonstrating awareness of some of the unique considerations involved with whistleblowing, you can encourage reports of valuable information while maximizing your source’s protection.
    • If an employee has come to you with information about serious wrongdoing, whether the information relates to human rights abuses, environmental threats, or national security risks, journalists should exercise special care in communicating with the employee source to ensure that the employee retains the flexibility to consider all options in making choices about the best, and safest, ways to disclose information.

The Whistleblower Project by the Society of Professional Journalists in the US hosts a collection of articles on the topic, including a discussion of the need for secure communications.

Covering Whistleblowers: 6 Tips for Journalists This 2019 article by Denise-Marie Ordway appeared on Journalist’s Resource. The six tips explained in the article are:

    2. Don’t focus on why whistleblowers come forward.
    3. Understand the differences between whistleblowers and “leakers.”
    4. Have a strategy for secure communication.
    5. Familiarize yourself with the whistleblower protection laws that apply to the whistleblower you’re reporting on.
    6. Know where to go for help understanding whistleblowing issues.

The Art of Working with Whistleblowers. In this article, features lessons from Meirion Jones, an editor for the Bureau of Investigative Journalism (BIJ) in the United Kingdom. “One of the most important measures, Jones said, is protecting your source’s anonymity and safety. Should there be the slightest danger of these being compromised, it is preferable to not run the story at all, or publish a significantly cut-down version, ”the article states.
