This guide breaks down how to evaluate vendor access across key dimensions, including visibility, frequency, and sensitivity, helping cybersecurity and compliance leaders in critical infrastructure build stronger, more defensible Third-Party Risk Management (TPRM) programs.

Key Takeaways

• Types of Vendor Access: Evaluate whether third parties have remote, physical, or logical access to systems, facilities, or data.

• Scope and Sensitivity: Understand what data vendors can view or interact with, and how sensitive or operationally critical that information is.

• Frequency and Justification: Assess how often vendors access your environment and whether that access is necessary and secure.
