"Zero trust is not a thing; it is an idea. It is not a product; it is a concept - it is a destination that has no precise route and may never be reached. But it is described very succinctly: trust nothing until the trust is justified. Justification starts with verifying every subject's identity and authority. This is the single constant in all zero trust journeys: they start with the subject's identity. Zero trust's reliance on identity, and identity's reliance on AI Two questions. Can you have zero trust without effective identity verification? No. Can you have effective identity verification in the age of AI? Maybe, and maybe not."
"There is universal agreement that you cannot have zero trust without effective identity management. "Zero trust is not possible without an identity-first approach - they are fundamentally interconnected. Trust cannot be verified if the identity itself cannot be verified," says Rob Ainscough, chief identity security advisor at Silverfort. "Zero trust and identity management are inseparable. Without trustworthy, continuously verified identities, the whole model collapses," adds Avinash Rajeev, cyber, data & tech risk leader, PwC US."
Zero trust functions as a conceptual destination and ongoing journey that mandates verifying every subject before granting trust. Verification begins with identity and authority, making an identity-first approach foundational. Effective identity management is universally considered necessary for zero trust. The rise of AI and the rapid growth of non-human identities—machines and processes—complicate identity verification. Traditional IAM systems designed for humans struggle to manage non-human identities, blurring trusted and untrusted boundaries. Experts disagree on the exact state and path to zero trust, and questions remain about whether robust, AI-resilient identity verification can be achieved in practice.
