greater connectivity being allowed as one moves further from the most critical OT assets. By adhering to
the Purdue Model, organizations can reap the benefits of connectivity while minimizing risk.

Don’t Save OT Security Until Overtime

The connectivity of modern manufacturing environments has made remote access security a top priority.

Traditional VPNs and perimeter-based defenses are no longer sufficient – manufacturers must instead
adopt a proactive OT security approach, defined by zero-trust security, identity-based access and
authentication, continuous monitoring and decisive action to secure assets. Only by securing access at
every level and ensuring that only the right people with the right credentials can reach critical systems
can manufacturers protect their most critical processes, ensure operational resilience, and mitigate costly
cyber-threats.

Adopting the right secure remote access tools is about more than just meeting regulations and going
through the motions of securing industrial environments – it’s about maintaining competitiveness and
growth trajectories in a world where a single hack can result in disaster.
