The Guardian SecureDrop is a tool for securely sending messages and documents to the Guardian. It uses the Tor network to hide where messages came from, and communication is encrypted in transit and on the server. Sources access it through an onion URL using the Tor browser.
ExoneraTor is a Tor Metrics service that maintains a database of IP addresses that have been part of the Tor network. It answers whether a Tor relay was running on a given IP address on a given date. It may store more than one IP address per relay and records whether a relay permitted transit of Tor traffic to the open Internet at that time.
This arXiv paper proposes an end-to-end scalable architecture for early identification of new Tor sites and daily analysis of their content. It is built on an open source big data stack including Kubernetes, Kafka, Kubeflow and MinIO, discovering onion addresses across several sources, downloading HTML from Tor, deduplicating with MinHash LSH and categorizing with BERTopic modeling. In 93 days it identified 80,049 onion services and characterized 90% of them.

Bloomberg Industry Group accepts confidential news tips through SecureDrop, described as a secure communication platform designed to protect anonymity. Bloomberg Industry Group controls the server, which stores submitted information in encrypted form. The page advises against using home, office or employer networks and devices, recommending public wifi and devices the source controls. Signal and postal mail are listed as alternative methods.
Forbes SecureDrop is an open-source whistleblower submission system that media organizations such as Forbes use to securely accept documents from and communicate with anonymous sources.
