Abstract

Concepts and technologies are disclosed herein for filtering network traffic using protected filtering mechanisms. An indication that traffic is to be filtered can be received, and a hash key, a signature representation, and an obfuscated signature can be identified or generated. The hash key and the signature representation can be provided to a first device without exposing the contents of the signature to the second device, and the obfuscated signature can be provided to a second device without exposing the contents of the signature to the second device. The first device and the second device can execute independent operations to collectively determine if the traffic is to be filtered.
