A network traffic monitoring service provides a way to search network traffic intercepted by a network firewall while protecting the privacy of non-matching network traffic that traverses the firewall. Network traffic is parsed and processed into a set of tokens. In various implementations, the tokens may be words, HTML tags, data values, or other searchable units of information. The tokens are converted into a set of hashes, and the set of hashes is provided to the traffic monitoring service. A search authority submits a search request to the traffic monitoring service. Search terms of the search request are converted to a set of hashes to produce a hashed search request. The traffic monitoring service processes the hashed search request against the set of hashes provided by the network firewall to determine whether the network traffic represented by the set of hashes matches the search request.
