How to Secure Remote Access to OT/IoT Without All-or-Nothing Risk

Operational technology environments face rising cyber threats, yet many still use outdated remote access methods. VPNs, rigid firewall rules, and PAM tools often fail to secure critical assets like PLCs, leaving systems vulnerable to breaches and ransomware. As OT networks grow, legacy approaches lack the control needed to ensure safety and uptime.

This brief explores how zero trust principles enable secure, identity-driven remote access without disrupting infrastructure. Learn about:

• Replacing all-or-nothing permissions with least-privilege controls
• Securing OT-IT DMZs without excessive firewall ports
• Unified monitoring and compliance

Modern strategies enhance OT security.
