Qadium Inc provides technology that monitors devices for cybersecurity applications. The company provides Internet scale sensing to index all public facing devices, and it is the first company to offer customer-specific alerts and automated change detection at global Internet scale. Qadium provides results in its SaaS platform, Expander, which runs in common web browsers. Expander gives users the unique ability to explore years of historical observations of devices on their networks, aggregate counts of device observations on third party networks, and access risk analytics. Qadium's proprietary datastore allows for the contextualization of all device observations relative to true global distributions. Qadium's technology can help users react rapidly to security events; better understand how their networks appear to malicious actors; evaluate risk; and resolve asset management discrepancies, such as those introduced by mergers, acquisitions, or large numbers of autonomous business units, which are impossible to discover with a local-only view. The company was seeded by the Defense Advanced Research Projects Agency (DARPA) to develop breakthrough technologies to analyze multi-petabyte heterogeneous streaming data.
