# Legacy Systems

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

Effective management requires balancing operational continuity with the need for modern security and data integration.

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.
