Strengthen Manufacturing and Industrial OT Security
Refresh your Purdue Model security with the power of zero trust.
Modernize manufacturing cybersecurity without disruptions
Reduce or eliminate your attack surface
Stop sophisticated ransomware incidents
Rapidly detect suspicious activities
The Problem
Most manufacturing attacks start in IT systems before spreading into OT. Attackers gain initial access with stolen VPN credentials, and then exploit flat networks, shared domains, and trusted protocols to move laterally.
Suspicious outbound activity, such as data exfiltration, often goes undetected. Without even touching PLCs, attackers can encrypt critical systems like HMIs and engineering workstations, grinding production to a halt.

FAQ
Zero trust protects OT systems by enforcing strict access controls and microsegmentation. Ensuring only authorized users and devices can communicate with OT systems reduces the risk of lateral threat movement. Meanwhile, early detection of suspicious activity helps prevent ransomware incidents and unauthorized access that could compromise systems or operations.
IT/OT convergence is increasing cyber risk for manufacturing networks as attackers exploit flat networks to move laterally from OT to IT systems. Zero trust minimizes this attack surface by preventing unauthorized access, enforcing granular segmentation, and securing communications, even in legacy environments. This helps protect uptime while defending critical systems.
Yes, zero trust can be implemented seamlessly without disrupting manufacturing operations. Solutions like agentless, browser-based access and automated microsegmentation ensure production runs without downtime. By replacing vulnerable VPNs and firewalls with modern zero trust approaches, manufacturers can improve security without compromising uptime, safety, or user experience.
