PingID

PingID (built by the massive enterprise security titan Ping Identity) is an absolutely colossal, heavily entrenched, and deeply trusted platform that operates as a major, high-end alternative to Duo and Okta. Ping Identity built a massive global empire by explicitly focusing on "The Most Complex, Hybrid Legacy IT Environments on Earth." The absolute core differentiator of PingID is its "Unshakeable Legacy Integration and Custom Policy Engine." While modern startups use 100% cloud apps, Fortune 500 banks still have ancient, 20-year-old mainframe applications sitting in an on-premise basement. PingID is mathematically engineered to wrap modern, cloud-based MFA Push Notifications around those ancient, legacy systems without breaking them. Because it completely solved the terrifying nightmare of securing ancient corporate mainframes, offering unparalleled on-premise hybrid support and massive federation capabilities, it is the inescapable standard for global banking, insurance, and massive corporate mergers.
