Session description

Speaker: Letitia Combes

Industrial environments are built to last. A PLC installed in 2010 may still be running today — same firmware, same configuration, same certificates. And therein lies the problem.
Machine identities in OT are everywhere. Every PLC, every IIoT device, every Scalance switch that communicates across your network carries — or should carry — a digital identity in the form of a certificate. These certificates are the foundation of secure machine-to-machine communication, Zero Trust architectures, and regulatory compliance under frameworks like IEC 62443 and NIS2.
Yet in most industrial environments today, managing these identities is still a manual process.
Teams track certificates in spreadsheets. Renewals are triggered by expiry alerts — if they' ...
