A server is configured to communicate with a group of clients over a network. Each of the clients obtains a corresponding informational message comprising security-related information such as an indication of compromise (IOC), inserts noise in the information message to generate an anonymized message, and communicates the anonymized message to the server. The anonymized messages communicated by the respective clients to the server may be configured so as to prevent the server from identifying any individual client associated with a particular one of the anonymized messages, while also allowing the server to extract from the anonymized messages collectively one or more characteristics of the underlying informational messages. A given client may insert noise in an informational message by, for example, selecting a noise value from a specified range of noise values, and combining the informational message and the selected noise value to generate the anonymized message.
