About Artemis
Artemis Security is a New York-based AI-native cyber defence platform that emerged from stealth in April 2026. It is building a centralized AI "brain" and agent network to detect and contain threats across applications, users, machines, and infrastructure — replacing rule-based SIEM/EDR patterns with adaptive models that keep pace with AI-powered attacks. Founded in late 2025 by CEO Shachar Hirshberg (formerly product lead on Amazon GuardDuty) and CTO Dan Shiebler.
