Siemens' OT Security Needs Centralized Certificate Management
With the TIA Portal and platforms like WinCC Unified, Siemens Industry is clearly strengthening its security capabilities. ✔️ Encrypted communication ✔️ Certificate-based authentication ✔️ Hardened PLCs, HMIs and drives Technically strong. No doubt. But let’s be honest: Where is the truly practical solution for centralized certificate management? Handling devices one by one, manually replacing certificates, tracking expiration dates – that doesn’t scale. And what happens in the mid-2030s when the certificates we’re creating today start expiring at scale? Security doesn’t end with implementation. It starts with lifecycle management. Siemens Industry – when will we get an integrated, industrial-grade certificate management solution for our OT systems? How are you handling this in your projects today? #OTSecurity #Industry40 #TIAportal #Cybersecurity
