In a zero trust architecture, identity replaces the traditional, physical air gap
as the primary line of defence. As industrial networks become more interconnected,
relying on physical isolation is no longer a viable strategy. Instead, robust authentication
and authorisation ensure that only verified users and devices can access specific
assets, regardless of their location. This shift allows for secure remote access
while maintaining the rigorous control once provided by isolation. Our post on [modern identity strategies](https://www.agilicus.com/a-pragmatic-blueprint-for-industrial-cyber-security/)
explores this transition.
