About:
Vectorscan is a high-performance regular expression matching library, forked from Hyperscan. It is optimized for modern CPU architectures, including ARM64 and RISC-V, providing multi-pattern matching capabilities. The library excels in network intrusion detection and data loss prevention systems where speed and accuracy are critical.
Key Features:
  • SIMD-accelerated pattern matching
  • Support for PCRE-compatible syntax
  • Multi-pattern matching and streaming
  • Optimized for ARM64 and RISC-V
Use Cases:
  • Network Intrusion Detection Systems (NIDS)
  • Data Loss Prevention (DLP) scanning
  • Content filtering and classification
  • Log analysis and processing
Alternatives:
  • Hyperscan – The original Intel-optimized library; Vectorscan provides broader architecture support.
  • PCRE2 – A mature regex library, but generally slower for multi-pattern matching than Vectorscan.
