SecureDrop is a widely used open source whistleblower submission system that allows journalists, media organizations, and nonprofit groups to securely receive documents and communicate with anonymous sources. Originally developed with contributions from Aaron Swartz and now maintained by the Freedom of the Press Foundation, the platform is considered one of the most trusted tools for investigative reporting and secure disclosures.
The system is designed to eliminate common surveillance risks associated with email, messaging apps, and traditional communication channels. SecureDrop operates over the Tor anonymity network, which helps protect the identity and location of whistleblowers while encrypting all submissions both in transit and at rest.
One of SecureDrop’s key strengths is its hardened operational security model. It removes third party intermediaries entirely by allowing organizations to host their own infrastructure. Journalists access submitted materials using a carefully segmented workflow that includes air gapped computers and encrypted storage, significantly reducing the risk of hacking, tracking, or metadata exposure.
SecureDrop is used by major investigative news organizations around the world, including outlets like ProPublica, The Guardian, and The Washington Post. These organizations rely on the platform to receive sensitive tips, leaked documents, and insider information while protecting the safety of their sources.
The platform also supports anonymous two way communication. After submitting information, sources receive a unique code name that allows them to check for replies and continue conversations without revealing their identity. This makes it possible to verify information, request clarification, and build investigative cases while maintaining strong anonymity protections.
For resistance movements, investigative journalism, and accountability projects, SecureDrop provides a high security, field tested solution for collecting sensitive information. It is particularly valuable in environments where surveillance, retaliation, or legal risk make traditional communication unsafe.
