Ping Identity

The Ping Identity Platform is a comprehensive control plane that secures digital interactions across customers, workforce, partners, and AI agents. Trusted by a proven install base of the world’s largest enterprises, the platform guarantees high stability, resiliency, and uptime. It combines Core IdP Services with Universal Services to cover the entire identity lifecycle: Manage (lifecycle, relationship, and directory data), Access (SSO, MFA, passwordless, authorization, and JIT privileged access), Govern (access requests, reviews, and segregation of duties), Identify (verifiable credentials, identity verification, and zero-knowledge biometrics), Protect (real-time threat protection), and Orchestrate (drag-and-drop journey design). To secure the agentic enterprise, Ping addresses AI across three distinct fronts. We "Protect Against AI" by stopping deepfakes and AI-driven fraud. We "Trust AI" by securing AI agents via strict governance and privileged access controls. We enable teams to "Build with AI" using our AI-first Headless Identity foundation, which allows builders and AI agents to operate Ping programmatically, and Helix embeds AI capabilities directly into our admin consoles to assist with configuration and troubleshooting. Organizations require architectural flexibility to meet stringent security and compliance mandates. Ping offers unmatched hybrid deployment options: Multi-tenant SaaS, Dedicated-tenant SaaS, Self-managed Software, Secure Containers, and government-grade FedRAMP & DoD IL5 environments. Through open standards interoperability and a robust integration marketplace, the platform “works with” your existing stack, supporting a practical extensibility and maturity model that lets you start small and scale. Ping backs this scale with a superior customer experience, expert Customer Care, and a global Partner Network. We prioritize ease of use through multi-modal admin options and accelerators. For example, the PingOne Design Center provides wizard-driven onboarding that generates production-ready authentication flows in under five minutes—eliminating the trade-off between simplicity and enterprise-grade flexibility.
