We present here the work developed by NBSO/Brazilian CERT, in the ``Brazilian Honeypots Alliance -- Distributed Honeypots Project'', to centralize the data gathered in several honeypots and to process this data to be used for early warning and incident response. We shortly describe how the honeypots are deployed and how the data is centralized, then focus on how the data is being used by NBSO to generate statistics and to notify networks potentially compromised or infected.
