Zero Trust Considerations for OT
A practical framework for transitioning from perimeter-based security to continuous verification across cloud, network, and identity domains.
With the rapid acceleration of hybrid working, cloud migration, and decentralised corporate networks, traditional perimeter-based defence models are no longer sufficient to protect critical enterprise assets. This technical white paper by Airbus Protect addresses the shift towards a "Zero Trust" security posture—operating under the fundamental principle of "never trust, always verify." The guide explores how organisations can systematically implement granular access controls, micro-segmentation, and continuous identity authentication across their entire digital estate. By moving beyond legacy VPNs and static trust assumptions, Airbus Protect outlines a structured roadmap to minimise attack surfaces, contain potential breaches, and build long-term operational resilience.
