In manufacturing, legacy systems pose a strategic challenge. They contain technical debt and cyber-physical vulnerabilities, yet offer stable, proprietary logic and high reliability.

Virtual patching and secure gateways help organizations protect vulnerable assets from modern threats, allowing legacy systems to remain productive within a high-speed, data-driven IT/OT environment.
