Modern businesses run on millions of machine‑to‑machine connections: Autonomous AI Agents orchestrating work, CI/CD service accounts, SaaS OAuth apps, and API keys that keep data flowing. These Agentic and Non-Human identities outnumber humans ~45 to one, inherit broad, static privileges, sit outside IAM review cycles, and often persist long after their creators leave. Attackers exploit the gap: high-profile attacks against the US Treasury, Okta, and Microsoft (Midnight Blizzard) demonstrate how a single leaked token or hijacked agent can grant root‑level access across cloud and SaaS. While existing IAM solutions focus solely on human identities, Astrix provides security teams with continuous discovery of AI agents and NHIs, risk‑based prioritization, real‑time threat detection, and automated remediation. Fortune 1,000 enterprises such as Workday, NetApp, Priceline, Hubspot, Figma and Agoda already rely on Astrix to securely unleash AI-driven automation.
