Autonomous Vulnerability Remediation As A Foundation For Zero-Trust Architecture In Enterprise Data Center Ecosystems

Abstract

Zero-trust architecture (ZTA) has become the dominant security reference model for enterprise data center ecosystems, yet its practical implementations are structurally incomplete. The framework’s "never trust, always verify" posture governs access to resources with considerable rigor but leaves unaddressed whether those resources are actually free of exploitable vulnerabilities. The National Vulnerability Database (NVD) now publishes well above 29,000 Common Vulnerabilities and Exposures (CVEs) annually, a volume that manual remediation workflows cannot absorb, and Ponemon Institute data place the industry mean time to remediate (MTTR) for critical vulnerabilities at approximately 60 days. This paper argues that zero-trust must be extended from access verification to autonomous vulnerability elimination, and it develops a five-level zero-trust maturity model that places autonomous remediation at Level 5. A five-stage remediation pipeline, discovery, prioritization, patch identification, staged deployment, and verification, is combined with a confidence-gated action policy that partitions patches by model-derived probability of success. Under industry-reported adoption of this architecture, MTTR falls by approximately 81 percent to near 2.7 days, the CVE backlog contracts by approximately 78 percent, autonomous remediation reaches the 83 percent share, and the enterprise zero-trust posture score rises from a baseline near 42 to near 87 on a hundred-point scale. The article positions autonomous remediation as the infrastructure layer that makes zero-trust operationally complete rather than aspirational.
