▪ Increased Visibility - Comprehensive logs and analytics detect anomalies and accelerate
response times.
▪ Centralized Control - Unified policies stay consistent across all suppliers, partners, and users.
▪ Least Privilege Access - Strict access permissions limit damage from compromised accounts.
▪ Adaptive Trust Levels - Access privileges dynamically adapt based on risk profiles of users and
entities.

Best Practices for Implementing Zero Trust Access Strategically

Deploying zero trust access across complex, multi-party supply chains requires careful planning. Here
are some best practices to help you smooth the transition:

▪ Phase Incrementally - Initially deploy zero trust for a single app, vendor, or workflow before
expanding its scope.
▪ Enforce Least Privilege - Scrutinize and pare down all access permissions to essentials only.
▪ Use Strict Access Controls - Require multi-factor authentication, endpoint verification, and
centralized user directories.
▪ Segment Your Network - Partition networks into enclaves and gradually implement micro-
segmentation.
▪ Involve Stakeholders - Get buy-in from leadership, suppliers, partners, and end-users through
regular communication.
▪ Reassess Regularly - Adapt controls to address new risks, and re-evaluate access permissions
frequently.

How Can Supply Chains Avoid Pitfalls With ZTA?

Zero trust access enhances security but also poses potential drawbacks if deployed incorrectly. Common
missteps include:
▪ Overly restrictive access that reduces productivity
▪ Rolling out controls too quickly, causing outages
▪ Complex policies that are challenging to manage
▪ User frustration due to lack of guidance on changes
▪ Clashing with regulatory compliance requirements

By taking an incremental approach and emphasizing user education, your organization can maximize
benefits while minimizing disruption.
