Company Description

Arkion Identity Systems is revolutionizing identity governance with the first-ever Non-Human Identity Governance (NHIG) platform. Designed specifically for AI agents, certificates, and machine identities, Arkion addresses challenges that traditional Identity and Access Management (IAM) platforms, like Okta and Ping, cannot solve. Our platform offers features such as passive discovery, certificate-based identity, real-time risk scoring, auto-rotation of credentials, and compliance-friendly audit trails.

Based on innovative technology, Arkion empowers enterprises to secure and govern their extensive networks of non-human identities. Join us and be part of the future of identity management at Arkion.ai.
