Himaya is an agentic AI-native workspace security company. We build autonomous platforms that protect the three layers every cloud enterprise depends on: email, data, and identity. Most security tools watch and warn. Himaya's platforms think, decide, and act. Our agents work across Microsoft 365, Google Workspace, and multi-cloud environments to autonomously detect threats, enforce least-privilege access, and continuously monitor data security posture. No manual triage. No alert fatigue. Security that runs itself. We are built for enterprises operating under real regulatory pressure such SOC2, ISO27001, SEC, SAMA, NCA ECC, PDPL, MAS TRM -where fragmented tooling and reactive security operations are no longer good enough.
