HYPERSCAN
High-performance multi-pattern regular expression matching
BSD-3-Clause
ABOUT
Matching thousands of regexes on a live stream with PCRE-style backtracking cannot keep up with NICs. Hyperscan compiles many patterns into SIMD automata so log scanners, DPI, and content filters search packets and files at line rate.
INTEGRATION GUIDE
1. Scan logs or packets against thousands of regexes at once
2. Build a DPI or content-filter pipeline on SIMD automata
3. Match streaming buffers without backtracking catastrophic cases
4. Replace a slow multi-pattern grep in a security or telemetry path
