Hyperscan is a high-performance multiple regex matching library. It follows theregular expression syntax of the commonly-used libpcre library, but is astandalone library with its own C API.

Hyperscan uses hybrid automata techniques to allow simultaneous matching oflarge numbers (up to tens of thousands) of regular expressions and for thematching of regular expressions across streams of data.

Hyperscan is typically used in a DPI library stack.
