Privileged Access Management: Buyer's Guide for Security Architects

Privileged accounts are the highest-value target in enterprise infrastructure. Domain administrators, service accounts with broad API access, and database credentials with write permissions represent the attack surface that ransomware operators and nation-state actors prioritize once they have a foothold. Privileged Access Management (PAM) is the control category that governs how those accounts are vaulted, monitored, and constrained.

The Gartner Magic Quadrant for PAM consistently places three vendors in the Leaders quadrant: CyberArk, BeyondTrust, and Delinea. But the Magic Quadrant does not tell security architects which platform is right for a specific organization’s infrastructure, team capacity, or compliance requirements. This guide provides the evaluation framework that the Magic Quadrant does not.

What PAM Actually Controls

Before evaluating vendors, architects should be precise about what problem they are solving. PAM addresses four control objectives:

Credential vaulting: Storing privileged credentials (passwords, SSH keys, API tokens, certificates) in an isolated, encrypted repository where access is governed by policy and every retrieval is logged.

Session management: Recording and monitoring privileged sessions — remote desktop, SSH, database connections — so that every action taken under a privileged account can be reconstructed for audit purposes.

Just-in-time (JIT) access: Provisioning privileged access only for the duration of a specific task, then automatically revoking it. JIT eliminates standing privileged access, which is the configuration most exploited by attackers.

Least-privilege enforcement: Ensuring that accounts have only the permissions they need for their defined function. For endpoints, this means removing standing local administrator rights and substituting policy-based privilege elevation.

A mature PAM deployment addresses all four. Many organizations that have a PAM platform have only solved credential vaulting and have not implemented session management, JIT, or endpoint least-privilege — leaving significant attack surface open.

NIST SP 800-53 Requirements That PAM Satisfies

NIST Special Publication 800-53 Revision 5 is the foundational security control catalogue for federal information systems and is widely used as a baseline for state and local government security programs, including law enforcement agencies subject to CJIS Security Policy requirements.

The control families most directly addressed by PAM are:

AC (Access Control): AC-2 (Account Management), AC-3 (Access Enforcement), AC-5 (Separation of Duties), AC-6 (Least Privilege), and AC-17 (Remote Access) all map to PAM capabilities. AC-6 specifically requires restricting privileged account use to tasks that require those privileges — a control JIT provisioning satisfies directly.

AU (Audit and Accountability): AU-2 (Event Logging), AU-3 (Content of Audit Records), and AU-9 (Protection of Audit Information) require that privileged actions be logged with sufficient detail to reconstruct events. Session recording in PAM produces the evidence record that AU controls require.

IA (Identification and Authentication): IA-2 requires multi-factor authentication for privileged account access. Most PAM platforms enforce MFA as a condition of credential retrieval.

CM (Configuration Management): CM-5 (Access Restrictions for Change) limits who can make configuration changes to systems — a control that PAM’s credential management and session monitoring directly support.

For CJIS-covered agencies, CJIS Security Policy v6.0 (released December 2024) formalizes logging and access control requirements that align with the NIST framework and explicitly require privileged access controls for systems handling criminal justice information. PAM is a compliance infrastructure investment, not just a security one.

CyberArk: Maximum Depth, Maximum Operational Cost

CyberArk is the market reference platform. Its core architecture centers on the Digital Vault — an isolated credential storage layer that is air-gapped from the rest of the infrastructure and accessible only through the CyberArk Vault server. This architecture makes CyberArk the most defensible PAM platform in adversarial conditions: even a fully compromised domain controller cannot directly access vault contents.

CyberArk’s feature depth covers use cases that other platforms address partially or not at all: OT/SCADA environments, mainframe privilege management, cloud infrastructure entitlements management (CIEM), and developer secrets management. Its regulatory certification breadth is the widest in the category.

The trade-off is operational cost. CyberArk requires a dedicated PAM engineering team to operate effectively. Deployment timelines are measured in months, not weeks. The licensing cost is the highest in the category. For organizations with the engineering capacity and budget, CyberArk delivers the most comprehensive control posture. For organizations without that capacity, the investment does not achieve its potential.

Right fit for: Large enterprises with mature security programs, OT/SCADA environments, organizations with specific regulatory certification requirements, and agencies where the threat model justifies maximum depth.

BeyondTrust: Hybrid and Endpoint Coverage

BeyondTrust’s differentiation is endpoint privilege management combined with infrastructure PAM in a unified policy framework. Its Privilege Management for Workstations product removes standing local administrator rights and substitutes policy-based elevation — the control that many CyberArk deployments leave unaddressed at the endpoint level.

BeyondTrust is built for hybrid environments. Its cloud-native architecture supports quick deployment (often within a month, compared to multi-month CyberArk deployments) and integrates with Azure AD, AWS, and GCP identity controls without significant engineering overhead.

The trade-off is feature depth at the infrastructure layer. BeyondTrust’s vault architecture is less hardened than CyberArk’s Digital Vault in adversarial conditions. For organizations whose primary concern is endpoint privilege and cloud infrastructure, that trade-off is acceptable. For organizations with significant on-premises infrastructure and high adversarial threat, it requires evaluation.

Right fit for: Hybrid and cloud-first organizations, organizations that need to address endpoint privilege alongside infrastructure PAM, and organizations that need a production deployment without a large dedicated PAM team.

Delinea: Fastest Time-to-Value

Delinea (formed from the 2021 merger of Thycotic and Centrify) occupies the fastest-deployment, lowest-complexity position in the Leaders quadrant. Its Secret Server and Privilege Manager products are well-regarded for session recording and basic credential vaulting, and deployment timelines are typically the shortest in the category.

Delinea’s licensing is 30 to 40% lower than CyberArk for equivalent functionality, making it the leading choice for organizations with constrained PAM budgets. Its SaaS deployment options reduce operational overhead further.

The trade-off is depth at the advanced tier. Delinea’s CIEM capabilities, OT support, and developer secrets management are less mature than CyberArk’s. Organizations that grow their PAM requirements beyond Delinea’s capabilities often face a migration project — a cost that should be factored into the total-cost-of-ownership analysis at procurement.

Right fit for: Organizations that need a production PAM deployment quickly, cannot staff a dedicated PAM engineering team, or have budget constraints that make CyberArk’s licensing unsustainable.

Evaluation Criteria Security Architects Should Apply

The vendor shortlist should be built against these eight criteria, weighted by organizational priorities:

1. Vault architecture hardening: How is the credential store isolated from the broader infrastructure? What would a domain-level compromise expose?

2. Session recording coverage: Which session types are recorded — RDP, SSH, database, web application? What is the retention and retrieval architecture?

3. JIT access support: Does the platform provision time-limited access natively, or does JIT require third-party integration?

4. Endpoint privilege management: Is endpoint least-privilege included in the platform, or is it a separate product with separate licensing?

5. Cloud and SaaS coverage: How well does the platform manage secrets and privileged access for cloud workloads, SaaS applications, and CI/CD pipelines?

6. NIST 800-53 and CJIS compliance documentation: Does the vendor publish a compliance matrix mapping platform controls to specific NIST control IDs? For CJIS-covered agencies, has the platform been validated for CJIS v6.0 requirements?

7. MFA enforcement: Is MFA enforced for credential retrieval by architecture, or configurable and potentially bypassable?

8. Deployment timeline and team requirements: What is a realistic time-to-production for a team of your size, and what ongoing staffing is required?

The Proof-of-Concept Phase

No evaluation framework substitutes for a proof-of-concept against your actual environment. The specific variables that matter — whether your Active Directory topology matches the vendor’s reference architecture, whether your session recording infrastructure can handle the volume of privileged sessions in your environment, whether your team can operate the platform without vendor professional services — are only visible in production conditions.

Proof-of-concept scope should include: credential vaulting for a representative sample of privileged accounts, session recording for the top three privileged access paths in your environment (typically RDP to domain controllers, SSH to critical servers, and database access), and JIT provisioning for at least one administrative workflow.

The outcome of a structured POC is a performance baseline and a list of integration gaps — which is the information procurement decisions should rest on, not vendor marketing materials or analyst rankings alone.

What Poor PAM Governance Looks Like in an Audit

For agencies subject to CJIS audits, OIG reviews, or any federal compliance assessment, PAM governance gaps present predictably. The most common finding patterns are:

• Service accounts with non-expiring passwords and no session monitoring
• Domain administrator accounts used for routine tasks rather than dedicated to privileged functions
• No audit log for credential access — the vault exists but retrieval is not logged
• MFA configured as optional rather than enforced by architecture
• No JIT provisioning — standing privileged access persists indefinitely

Each of these maps directly to a NIST SP 800-53 control and, for CJIS-covered agencies, to a specific CJIS Security Policy requirement. An agency operating a PAM platform that has not addressed these configurations has compliance documentation without compliance posture — a distinction that auditors are experienced at identifying.

A PAM deployment is complete when the platform controls are operating against the actual privileged account population, not when the platform is installed.
