The Security Information Exchange (SIE) is a private framework of trusted organizations dedicated to the creation of a real-time globally trusted exchange of information. Participants can operate real time sensors that upload and/or inject live data to SIE infrastructure, and other participants can subscribe to this data either in real time through limited and anonymized download, based on public or private agreements.

The SIE infrastructure promotes trusted exchange of information among peers to tackle security issues. It provides the capability for private-public partnerships to exchange this information, and thereby fosters tighter collaboration for pro-actively detecting and reacting to malicious and criminal behavior on the Internet. All access and use, either commercial or noncommercial, must be in the public interest.
