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
