Beyond the Perimeter: A Comparative Analysis of Zero Trust Framework Implementations in Hybrid Enterprise Environments
Year: 2025
Type: article
Abstract: This article addresses the transition from traditional perimeter-based security to Zero Trust models within hybrid enterprise environments, synthesizing guidance from prominent frameworks including Forrester, NIST, DISA, and the UK NCSC. Through comparative analysis, key architectural components and implementation strategies emerge across network, infrastructure, application, and data layers. The maturity progression from discovery to advanced implementation highlights layer-specific security controls essential for successful Zero Trust adoption. Particular attention focuses on unique challenges in hybrid environments where consistent policy enforcement must bridge on-premises and cloud infrastructures. The articles suggest that organizations can effectively navigate seemingly disparate framework recommendations by adopting a layered hardening approach aligned with risk-based priorities and supported by continuous monitoring capabilities. This contribution bridges the gap between theoretical Zero Trust principles and practical security implementation in complex, heterogeneous enterprise environments.
