Hyperscan is a high-performance multiple regex matching library. It follows the regular expression syntax of the commonly-used PCRE library, yet functions as a standalone library with its own API written in C.

Hyperscan uses hybrid automata techniques to allow simultaneous matching of large numbers (up to tens of thousands) of regular expressions, as well as matching of regular expressions across streams of data.

Hyperscan is typically used in a DPI library stack.

Hyperscan began in 2008, and evolved from a commercial closed-source product 2009-2015. First developed at Sensory Networks Incorporated, and later acquired and released as open source software by Intel in October 2015.
