## What it is
Hyperscan is a high-performance C library (written in C++) for simultaneously matching large numbers of regular expressions, using hybrid automata techniques. It follows PCRE syntax, supports stream matching, and is commonly used in deep packet inspection (DPI) stacks.

## Use cases
- match tens of thousands of regexes simultaneously
- deep packet inspection regex engine
- scan network traffic streams for patterns
- fast multi-pattern string matching in C/C++
- PCRE-compatible regex matching at high throughput
- intrusion detection signature matching

## When to choose
- you need to match many regex patterns at once with high performance
- you are building DPI, IDS/IPS, or network security tooling
- you need stream-based regex matching over data flows
- you want a C API with PCRE-like syntax

## When to avoid
- you need full PCRE feature coverage such as backreferences or complex lookarounds
- you need a simple, lightweight regex for a handful of patterns
- you want a high-level language regex without C/C++ integration
