IVIP: Beyond the Buzzword, Toward Identity Reality
Every few years, the identity industry gets a new acronym. Some fade quickly. Others reshape the way we think. The newest entry is IVIP — Identity Visibility & Intelligence Platforms.
Since Gartner added IVIP to their Hype Cycle, the debate has been lively. Analysts like Martin Kuppinger and Matthias Reinwarth have rightly asked:
