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

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

Hyperscan is typically used in a DPI library stack.


Information on building the Hyperscan library and using its API is available in the Developer Reference Guide.


Hyperscan is licensed under the BSD License. See the LICENSE file in the project repository.


The master branch on Github will always contain the most recent release of Hyperscan. Each version released to master goes through QA and testing before it is released; if you're a user, rather than a developer, this is the version you should be using.

Further development towards the next release takes place on the develop branch.
