Third-Party Vendors of Social Media Monitoring Tools for Law Enforcement Agencies

After obtaining public records related to third-party social media monitoring tools marketed to police departments, the Brennan Center is compiling information on the companies selling these tools.

Published: November 17, 2021

The Brennan Center filed public records requests with police departments in Boston, New York City, Los Angeles, Baltimore, and Washington, D.C., seeking information about their use of third-party social media monitoring tools. The resulting documents revealed new information about how these tools are used and the relationships between law enforcement and these third-party vendors.

Below is information on what we know about each of the companies, including their data sources, the tools’ purported capabilities, and publicly available information about the companies’ public-sector clients, as well as relevant documents acquired through the Brennan Center’s public records requests. We will update this resource if we receive additional relevant documents.
