FAQ
Questions, answered.
Is Cortrova an ERP or an MES?
Cortrova is an AI-native manufacturing ERP that also covers shop-floor execution across its production, quality, and maintenance modules. Plex is a smart-manufacturing platform with particularly deep MES capabilities plus ERP. If MES depth on a cloud platform is the priority, weigh Plex carefully; if AI-native ERP breadth and air-gapped deployment matter more, Cortrova fits.
Can Cortrova run air-gapped where Plex is cloud-only?
Yes. Cortrova deploys on-premises or fully air-gapped with on-premises AI models, so controlled data stays in-boundary. Plex is delivered as cloud SaaS, which suits many plants but is a different model for classified or ITAR environments.
How does the AI compare?
Cortrova embeds 65 agents directly in its modules so predictions and automation are part of the workflow. Plex offers strong production monitoring and analytics. The practical difference is whether AI is native to every workflow or provided as platform analytics.
