-
Establishing repeatable methods to improve visibility into unknown or unmanaged technologies, services, connections, and changes within manufacturing environments
-
Conducting recurring technical reviews that help identify newly introduced risks and strengthen the security, reliability, and resilience of 3M’s global manufacturing operations
