When handling confidential sources, maintaining their anonymity is paramount. I would ensure all communications are secure, using encrypted methods for correspondence. I'd avoid sharing identifying details and, where necessary, use pseudonyms or general descriptions to protect their identity. Trust is built through clear agreements on confidentiality, and I would be transparent about the use of their information while strictly adhering to ethical guidelines. Any sensitive information would be handled with the utmost care, balancing the source's need for privacy with the integrity of the content provided.

I believe that we should approach this with the media's policy in mind. Is this source essential? Will you be able to verify their information with facts? And if so, do you have "on the record" sources? Going on the record has a cost for many sources, but it undeniably reinforces the impact of an investigation (see: MeToo investigations).
