EY Cyber Factory

Your business challenge

Organizations in advanced manufacturing facing separations or transactions encounter unique challenges. Separating operational technology (OT) during a corporate transaction involves unbundling fragility, dependencies, and risks. When cybersecurity is treated as a parallel workstream, it often leads to missed milestones, fragmented controls, and long-term security debt.

Solution benefits

Our factory-style model integrates architectural scaffolding, execution discipline, and separation planning into a single lifecycle. It avoids theoretical maturity models in favor of site-ready controls, standardized artifacts, and practical implementation paths.

Use case

The EY Cyber Factory Model has delivered significant results for clients. For instance, a Fortune 500 spin-off achieved a 30% reduction in inherited risk and exited TSAs 25% faster than planned. In the advanced manufacturing sector, clients saw a 40% improvement in OT security readiness, enabling operational independence from day one. Additionally, the model's rapid assessments and tailored migration roadmaps have led to a 50% reduction in deferred risk, promoting long-term resilience. These quantitative results demonstrate the model’s capability in accelerating cyber resilience during corporate transactions.

Solution features and functionality

Nine capabilities that embed resilience from day one:

• Active Directory (AD) Management
• Identity & Access Management (IAM) and Governance (IGA) for OT
• PKI and Certificate Management
