What is vendor privileged access management (VPAM)?

Third-party vendors often require privileged access to internal systems—but unmanaged vendor access is a major security risk. Learn how vendor access management works, why it matters, and how organizations can control and monitor third-party access to protect critical systems.

If you’re in the cybersecurity world, you’re probably familiar with the term privileged access management. It refers to advanced access controls and processes that protect the privileged credentials of internal users from compromise and limit the damage if those credentials are compromised.

Bad actors often seek to obtain or escalate privileged credentials because doing so allows them to appear as legitimate, authorized users, which, in turn, enables them to move through systems and networks as far as access permissions allow. The scope of the resulting damage can be devastating.

Vendor access management refers to the policies, processes, and technologies used to control and monitor how third-party vendors access enterprise systems and remote administrative environments. As with privileged access management, vendor access management is a critical component of Zero Trust security strategies, which require organizations to continuously verify users and restrict access to only the resources necessary for specific tasks.

By employing vendor access management, you add a crucial layer of protection to any cybersecurity defense strategy.

VPAM: PAM for vendor access management

The high risks associated with privileged access make access management tools essential for enterprises of all sizes in all industries. In healthcare specifically, recent research found that over half of organizations (56%) experienced a third-party–related breach within the past year, and roughly two-thirds expect the number of data breaches to rise over the next 12 to 24 months. Furthermore, these types of breaches take the longest to contain and resolve.

This is where a specialized form of privileged access management, known as vendor privileged access management, comes into play. This software is specifically designed to manage privileged access for third parties, such as vendors, contractors, and service providers. The primary goal is to ensure that vendors receive only the enterprise system access required to complete their work, while maintaining visibility and accountability for every connection.

Why vendor access creates unique security risks

Third-party vendors often require remote administrative access to maintain software, infrastructure, or specialized equipment. Unlike internal employees, vendors operate outside the organization’s direct security controls, making it difficult to enforce consistent authentication policies, device security standards, or network restrictions. Without proper controls, vendor accounts can become a major attack vector for credential theft, lateral movement, and supply chain compromise.

How vendor access management works

Vendor access management platforms typically broker connections between external users and internal systems. Vendors authenticate through a secure portal, submit an access request, and receive time-limited access to approved systems. Instead of exposing credentials directly, the platform launches a controlled session via a secure gateway, retrieves the required credentials from a password vault, and records the session for auditing. When the session ends, access privileges are automatically revoked.

A modern vendor privileged access management platform should provide several core security capabilities:

• Secure credential vaulting
• Granular access controls
• Session monitoring and recording
• Just-in-time privileged access
• Automated access approvals

Together, these controls allow organizations to manage access to IT systems without exposing sensitive credentials or granting unnecessary permissions to third parties.

The following capabilities form the foundation of effective third-party access control.

Credential management for vendors and subcontractors

Credential security is one of the most critical elements of vendor access management. Privileged credentials used by vendors can provide extensive access to enterprise systems, making them a high-value target for attackers.

Best practices include:

• Storing credentials in secure password vaults
• Automatically rotating passwords
• Eliminating shared administrative accounts
• Injecting credentials into vendor sessions through a secure gateway to avoid directly exposing credentials

Strong credential management for subcontractors prevents external personnel from reusing credentials outside authorized sessions.

Granular access controls

Access controls determine who can access enterprise systems and what level of access they receive.

Organizations often use role-based access control (RBAC) to assign permissions based on defined responsibilities. RBAC simplifies administration by assigning permissions based on defined roles, helping enforce least-privilege policies so that users receive only the privileges they need for required tasks.

Vendor access management solutions allow organizations to implement:

• Role-based permissions
• Least-privilege access policies
• System-level access restrictions
• Network segmentation for vendor connections

These controls limit vendor access to only the systems required for their work, reducing the potential impact of compromised accounts.

Session monitoring and auditing

Visibility is essential when external users connect to internal systems.

Vendor access management platforms often include capabilities such as:

• Real-time session monitoring
• Session recording for privileged activity
• Comprehensive audit logs
• Alerts for suspicious behavior

These capabilities allow security teams to track vendor activity, investigate incidents, and maintain a detailed record of privileged access.

Just-in-time privileged access

Standing privileged access significantly increases the risk associated with vendor accounts. If credentials remain active when they are not needed, they create an opportunity for misuse or compromise.

Just-in-time (JIT) privileged access reduces this exposure by granting elevated permissions only when a task requires them.

Vendor access management platforms typically support JIT access by:

• Granting privileged access only when a request is approved or policy conditions are met
• Automatically provisioning access for a defined task or session
• Enforcing strict time limits on elevated privileges
• Automatically revoking privileges when the session ends

By eliminating persistent administrative privileges, organizations reduce the attack surface associated with vendor accounts while still enabling vendors to perform necessary tasks.

Automated access approvals

Vendor access requests must often be reviewed and authorized before privileged access is granted. Managing these requests manually can slow operations and introduce inconsistencies. Automated approval workflows help standardize and streamline this process.

Vendor access management systems may support:

• Policy-based approval workflows
• Automated routing of requests to designated approvers
• Conditional approvals based on role, system, or risk level
• Integration with ticketing or change management systems

Automated approvals ensure that privileged access requests are properly authorized while reducing administrative overhead for security and IT teams.

Strengthening vendor access security

As organizations expand their digital ecosystems, vendor access management has become a foundational component of enterprise cybersecurity. These solutions help security teams enforce strong access controls, protect privileged credentials, and maintain visibility into third-party activity.

Organizations seeking to improve vendor access security often implement specialized platforms that centralize vendor identity verification, credential management, session monitoring, and policy enforcement. Traditional remote access tools, internal-use privileged access tools, and shared administrative accounts were never designed to securely manage third-party access. As organizations rely on increasingly complex vendor ecosystems, centralized control over privileged vendor activity becomes essential.

For example, Imprivata Vendor Privileged Access Management provides healthcare and enterprise organizations with tools to securely manage vendor access to IT systems while maintaining visibility and control over privileged sessions.
