Why We Track AI-Native Separately

AI-native security represents the fastest-growing segment in cybersecurity. Companies in this sub-watchlist build their core detection and response capabilities on machine learning architectures, rather than adding AI as a feature to existing rule-based systems. The distinction matters for investors: AI-native companies demonstrate fundamentally different scaling characteristics and defensibility profiles.

Vigilance Security exemplifies this approach with its multi-source signal aggregation and real-time behavioral analysis. The 97.2% detection rate and 350%+ growth trajectory suggest the market is validating the AI-native architecture thesis.
