Hybrid work, software-as-a-service adoption, edge platforms, and multi-cloud deployment have dissolved the assumption that trusted users and devices operate inside a stable enterprise perimeter. Point controls such as virtual private networks, endpoint detection, cloud access security brokers, and multi-factor authentication remain important, but isolated enforcement can create inconsistent policy and blind spots across identities, devices, workloads, applications, and data. This paper proposes a context-aware zero-trust access-governance framework for hybrid and multi-cloud environments. The framework integrates identity assurance, device posture, workload identity, application sensitivity, network context, behavioral analytics, and threat intelligence into a continuous risk score. A policy decision point converts risk and resource sensitivity into allow, step-up, restrict, isolate, or deny actions, while distributed enforcement points apply least-privilege controls close to the requested resource. The design includes session re-evaluation, policy conflict resolution, privacy-preserving telemetry, evidence-ready logging, and fail-safe behavior when context becomes stale. A formal model defines trust as a time-bounded decision rather than a permanent property and separates authentication confidence from authorization. The paper also provides an implementation workflow and a reproducible evaluation protocol covering security effectiveness, user friction, latency, resilience, privacy, and forensic readiness. No empirical performance claims are made without measured data; instead, scenario-based hypotheses and acceptance criteria are specified for subsequent testing. The proposed architecture offers a unified research basis for evaluating cloud access controls that must protect distributed assets without undermining availability and legitimate remote work.
