Orion Security

Orion Security (ORION) is an AI-native data loss prevention platform that replaces traditional policy-based DLP with real-time contextual analysis of data in motion across SaaS, email, cloud, AI tools, and endpoints. Rather than relying on predefined rules, ORION's proprietary AI agents build a complete picture of enterprise data flows, enabling high-confidence risk assessment and autonomous prevention of data exfiltration without requiring manual policy configuration. Founded in 2024 by Nitay Milner (former Cisco/Epsagon) and Jonathan Kreiner, the company raised $32 million in Series A funding in early 2026 with backing from IBM and is headquartered in New York.
