Perimeter to Posture: A Roadmap to Zero Trust Maturity
TechTarget, Thursday, July 2nd, 2026
Organizations can reach zero-trust maturity through a phased, multiyear approach balancing cultural and operational change.
Zero trust marks a fundamental shift from perimeter-based security models, operating on never trust, always verify principles.
The strategy requires explicit verification of all access requests, enforcing least-privileged access, and assuming breaches may already exist.
Beyond technology, zero trust demands organizational alignment, executive sponsorship, and cross-functional governance.
A realistic implementation spans four to five years: Year 1 establishes identity management and infrastructure visibility, Years 2-3 expand controls across applications and data, and Years 4-5 optimize through advanced analytics.
