Team Cymru, Inc.

Team Cymru, Inc. is a privately held cybersecurity company headquartered in Lake Mary, Florida. Established in 2005, its core mission is to enhance global cybersecurity by working with public and private sector entities to identify, track, and disrupt threat actors and cybercriminals. The company focuses on delivering comprehensive visibility into global cyber threat activity.

Team Cymru's offerings are centered around its proprietary Pure Signal™ data ocean, which aggregates global network traffic and other data types to provide real-time threat intelligence. Key products include Pure Signal™ Recon, a threat intelligence query tool for analysts; Pure Signal™ Scout, designed to accelerate threat hunting and incident response; and the Total Insights Feed, which unifies risk scoring, domain intelligence, and contextual threat data. The company also provides various threat intelligence feeds, such as IP Reputation and Controller Feeds. Beyond its commercial solutions, Team Cymru operates a Community Services division, offering no-cost threat detection, DDoS mitigation, and threat intelligence to network operators, hosting providers, and over 143 CSIRT teams worldwide.

In recent years, Team Cymru has expanded its commercial market presence, transitioning from a security research firm to a broader solution provider. Joe Sander was appointed CEO in April 2025, succeeding founder Rabbi Rob Thomas, and the company has made strategic executive appointments to support growth initiatives. Recent developments include the launch of Pure Signal™ Scout and the Total Insights Feed, as well as partnerships with organizations like Interpol and integrations with platforms such as Microsoft Security Copilot. The company has also engaged in research on critical infrastructure vulnerabilities. However, its practice of selling internet telemetry data to government agencies, including for counterintelligence purposes, has drawn scrutiny regarding potential privacy implications and the alleged warrantless use of such data.
