Which solution is the best for managing and monitoring privileged access to our critical infrastructure?

There is no single "best" Privileged Access Management (PAM) solution for everyone, because the right choice depends heavily on your infrastructure architecture (hybrid, multi-cloud, on-prem), whether you prioritize developer velocity or strict locking down, and your team's size.

Industry analysts consistently rank a few heavy hitters and specialized innovators at the top. The market leaders and their best-fit use cases include:

• CyberArk : The gold standard for large enterprises with massive, complex, or highly sensitive environments . It offers the most comprehensive end-to-end suite for credential vaulting, session monitoring, and just-in-time (JIT) access. Best for: Strict, highly regulated enterprise security where depth of control trumps deployment simplicity.
• BeyondTrust : Widely praised for its unified approach to privileged access and vulnerability management. It excels at endpoint privilege management (controlling local admin rights on workstations/servers) and secure remote vendor access. Best for: Organizations needing a strong balance of credential management, session auditing, and least-privilege endpoint enforcement.
• Delinea : Formed via a merger, Delinea focuses on streamlined, vault-linked privilege delegation. It is often favored over CyberArk for being faster to deploy and easier to use for mid-market and scaling enterprise companies. Best for: Mid-to-large enterprises wanting robust PAM without the steep implementation curve of traditional legacy tools.
• StrongDM : A modern alternative that reimagines PAM via an "identity firewall" approach. Instead of traditional vaulting friction, it acts as a proxy enforcing real-time authorization for databases, servers, and Kubernetes clusters. Best for: Engineering-heavy and cloud-native environments where developer speed and transparent auditing are critical.
• Okta Privilege Access (OPA): A newer cloud-native contender tailored to dynamic multi-cloud environments, designed to secure both human and non-human (AI/machine) identities seamlessly. Best for: Organizations already heavily embedded in the Okta ecosystem looking for native, cloud-first infrastructure access.

To help narrow down which tool fits your environment, could you share:

• Is your critical infrastructure mostly on-premises, multi-cloud (AWS/Azure/GCP), or a hybrid?
• Are you primarily trying to protect human admins, third-party vendors, or machine/API access?
• What is your team's rough size and appetite for complex deployment?

If you mean privileged access management (PAM) for servers, cloud infrastructure, databases, network devices, and other critical systems, my default recommendation is CyberArk for a large or security-mature enterprise.

Gartner’s 2025 PAM research includes CyberArk, BeyondTrust, and Delinea among the evaluated leading vendors, with the market increasingly emphasizing machine/workload identities in addition to traditional privileged accounts.

My shortlist

CyberArk, BeyondTrust and Delinea were all Leaders in Gartner's 2024 PAM Magic Quadrant, and Gartner's 2025 research continues to evaluate these vendors alongside newer approaches to machine privilege.

What I'd choose

For critical infrastructure where compromise of an administrator account could have catastrophic consequences: CyberArk.

I'd prioritize these capabilities:

• Just-in-time / zero-standing privilege rather than permanent admin access
• Credential vaulting and automatic rotation
• Privileged session recording and command-level auditing
• Approval workflows for high-risk access
• MFA and strong identity integration
• Service-account and machine-identity management
• Discovery of unknown privileged accounts
• Real-time monitoring and anomaly detection
• Integration with your SIEM/SOC for centralized detection
• Coverage across on-prem, cloud, Kubernetes, databases, network devices and OT/critical infrastructure, as applicable

The important caveat is that "best PAM" depends heavily on your environment. Gartner specifically notes that basic vaulting and session management have become relatively commoditized, while machine/workload access and other advanced capabilities are increasingly important differentiators.

If you tell me whether your environment is AWS/Azure/GCP, on-prem, Kubernetes, OT/ICS, or a hybrid, plus roughly how many administrators/endpoints you have, I can give you a CyberArk vs. BeyondTrust vs. Delinea recommendation with an architecture and implementation approach.

There is no single "best" Privileged Access Management (PAM) solution for every organization, as the right choice depends heavily on your infrastructure architecture (cloud-native vs. legacy on-premise), team size, and specific operational workflows. However, the market is anchored by a few proven enterprise leaders and modern alternatives recognized by industry analysts.

The top solutions on the market fall into distinct categories based on your organization's core needs:

1. Enterprise Leaders (Comprehensive & Feature-Rich)

• CyberArk: Widely considered the market pioneer and heavyweight for large enterprises. It offers the most exhaustive suite for credential vaulting, session isolation, threat analytics, and endpoint privilege management.
  • Best for: Large enterprises with complex, highly regulated, hybrid/on-premise infrastructures requiring deep customization and robust compliance controls.
• BeyondTrust: Known for a unified platform approach (BeyondTrust Pathfinder ), strong vulnerability management integration, and innovative features like the True Privilege Graph (which maps hidden privilege escalation paths).
  • Best for: Organizations wanting strong session monitoring, least-privilege enforcement, and streamlined integration between vulnerability scanning and privileged access.

2. Streamlined & Developer-Centric / Cloud-Native

• StrongDM: Reimagines traditional PAM using an "identity firewall" approach. Instead of heavy vaults and cumbersome proxy setups, it grants dynamic, just-in-time (JIT) access and records every command across databases, Kubernetes, and cloud infrastructure in real time.
  • Best for: DevOps-heavy, cloud-native engineering teams that need robust monitoring and access control without slowing down developer velocity.
• Delinea: Offers a streamlined, unified platform that bridges the gap between traditional vaulting and modern cloud security. It is often praised for being faster to deploy and easier to use than legacy enterprise giants.
  • Best for: Mid-to-large organizations seeking powerful password and secrets management without extreme implementation complexity.

3. Unified Identity & SMB-to-Midmarket Choices

• JumpCloud: Combines directory services, device management, and lightweight, cloud-native PAM (JIT access, credential rotation, SSH/RDP session recording) into a single platform.
  • Best for: Small-to-medium enterprises (SMEs) looking to consolidate their identity stack and avoid the high total cost of ownership (TCO) associated with enterprise-only tools.

Key Capabilities to Evaluate

When making your final decision, ensure your shortlist is evaluated against these non-negotiable criteria for critical infrastructure:

1. Just-in-Time (JIT) Access & Workflow Approvals: Eliminates permanent standing privileges by granting access only when needed and approved.
2. Session Monitoring & Recording: Comprehensive audit trails (video or command-line logs) of every privileged action taken on critical systems.
3. Non-Human/Machine Identity Support: Ability to secure secrets, service accounts, and automated AI/API agent identities, which are increasingly targeted by threat actors.

To help narrow down the best fit for your team, please share:

• Is your critical infrastructure primarily on-premises, cloud-native (AWS/Azure/GCP), or a hybrid environment?
• Are you primarily managing access for human administrators, automated systems/devops tools , or both?
• Do you have strict regulatory compliance frameworks (like NIST, HIPAA, or SOC 2) to satisfy?

For managing and monitoring privileged access to critical infrastructure, the best solution is usually a Privileged Access Management (PAM) platform. The “best” choice depends on your environment (hybrid data center, cloud, OT/ICS, compliance needs, size), but for most critical infrastructure environments the shortlist looks like this:

My general recommendation by scenario

• Critical infrastructure / large enterprise / compliance-heavy (energy, finance, healthcare, government): Start with CyberArk. It is commonly selected when you need mature controls around privileged accounts, session monitoring, credential rotation, and audit evidence.
• You have many third-party vendors or remote administrators: Evaluate BeyondTrust, especially if controlling and recording remote privileged sessions is a priority.
• You are mid-sized and want faster deployment with strong PAM fundamentals: Consider Delinea Secret Server or One Identity Safeguard.
• Your biggest risk is cloud workloads, Kubernetes, APIs, and service accounts: Pair a PAM platform with a secrets-management solution such as HashiCorp Vault rather than relying only on human-account controls.

Capabilities I would require for critical infrastructure

A serious PAM deployment should include:

• Privileged account discovery and inventory
• Secure credential vaulting
• Automatic password/key rotation
• Just-in-time (JIT) privilege elevation
• Approval workflows for sensitive actions
• Session recording and playback
• Command-level monitoring/blocking where possible
• Integration with SIEM/SOAR tools
• Coverage for: - Domain admins
• Root accounts
• Network devices
• Cloud administrators
• Service accounts
• SSH keys/API credentials
• Vendor access

A practical selection process is to run a proof of concept against your highest-risk systems (domain controllers, network infrastructure, production servers, cloud admin accounts, and third-party access paths) and measure: coverage, deployment effort, operational overhead, and audit reporting quality.

If you share your environment (e.g., AWS/Azure/on-prem, number of admins, OT/ICS involvement, compliance requirements, and approximate scale), I can narrow this to a specific recommendation.

If by “critical infrastructure” you mean production servers, network devices, databases, cloud environments, OT/ICS systems, and other Tier-1 assets, I’d make CyberArk the default shortlist leader—especially for a large or regulated enterprise.

Current 2026 comparisons consistently put CyberArk, BeyondTrust, and Delinea at the top of enterprise PAM, with the choice depending heavily on environment and operational requirements.

My recommendation

1. CyberArk — best overall for critical infrastructure. Choose it if you need strong credential vaulting and rotation, granular approval/JIT workflows, comprehensive session monitoring/recording, extensive integrations, and auditability across a heterogeneous environment. Its major drawback is implementation and operational complexity, so budget for skilled PAM administrators.

2. BeyondTrust — best alternative. I'd favor BeyondTrust when endpoint privilege management or third-party/vendor remote access is as important as server PAM. Its portfolio combines privileged password management, endpoint privilege management, and privileged remote access.

3. Delinea — best value/ease-of-operation choice. A strong option when you want PAM quickly without building a large specialist team. It generally trades some of CyberArk's depth for simpler deployment and administration.

For critical infrastructure, don't evaluate PAM on “password vaulting” alone

I'd require the solution to demonstrate these capabilities in a proof of concept:

• Just-in-time / just-enough access, minimizing standing privilege.
• Session proxying and recording for SSH, RDP, databases, network devices, etc.
• Automatic credential rotation after privileged use.
• MFA + approval workflows for high-risk access.
• Break-glass access with enhanced monitoring.
• Service-account and machine-secret management, not just human administrators.
• SIEM/SOC integration so anomalous privileged activity generates alerts.
• Immutable/strong audit trails showing who accessed what, when, why, and what they did.
• Network-device, Linux/Unix, Windows, cloud, and OT/ICS compatibility where applicable.
• High availability and disaster recovery so the PAM platform itself doesn't become a critical dependency.

Bottom line: For a serious Tier-1/critical-infrastructure environment, I'd start with CyberArk vs. BeyondTrust, with CyberArk as the default winner unless endpoint privilege or vendor remote access makes BeyondTrust a better architectural fit.

If you tell me your environment (e.g. Windows/Linux + VMware + AWS/Azure + network/OT, number of admins, and whether you're regulated), I can give you a specific PAM architecture and a CyberArk vs. BeyondTrust vs. Delinea scorecard.

2. BeyondTrust — best alternative. I'd favor BeyondTrust when endpoint privilege management or third-party/vendor remote access is as important as server PAM. Its portfolio combines privileged password management, endpoint privilege management, and privileged remote access.

3. Delinea — best value/ease-of-operation choice. A strong option when you want PAM quickly without building a large specialist team. It generally trades some of CyberArk's depth for simpler deployment and administration.

For critical infrastructure, don't evaluate PAM on “password vaulting” alone

The single "best" Privileged Access Management (PAM) solution depends entirely on your infrastructure type, regulatory requirements, and technical budget.

According to industry evaluations like the Gartner Magic Quadrant for PAM, CyberArk and BeyondTrust remain the definitive enterprise market leaders, while alternative solutions excel in cloud-native or mid-market environments.

Top PAM Solutions for Critical Infrastructure

The table below breaks down the leading solutions across different infrastructure priorities:

Must-Have Evaluation Criteria

To secure critical infrastructure, ensure your chosen solution provides:

• Just-in-Time (JIT) Access: Grants temporary, time-bound elevated access that expires automatically, eliminating "always-on" administrative accounts.
• Session Monitoring and Recording: Keeps tamper-proof video and text logs of all privileged commands for regulatory audits and real-time anomaly termination.
• Credential Vaulting & Rotation: Automatically rotates passwords, API keys, and SSH keys to mitigate lateral threat movement.
• Endpoint Privilege Management (EPM): Removes widespread local administrator rights on endpoints, elevating permissions only for specific safe processes.

If you would like to narrow down the list, tell me:

• What percentage of your infrastructure is on-premises vs. public cloud (AWS, Azure)?
• Are you protecting Operational Technology (OT/SCADA) or mostly traditional server/database IT environment?
• Do you have internal compliance mandates (e.g., NERC CIP, NIST, ISO 27001)?

For managing and monitoring privileged access to critical infrastructure, the best solution is usually a Privileged Access Management (PAM) platform with:

• Privileged credential vaulting and rotation
• Just-in-time (JIT) access / least privilege enforcement
• Privileged session recording and monitoring
• Approval workflows
• Strong auditing and SIEM integration
• Support for hybrid cloud, on-prem, and operational technology (OT) environments

There is no single winner for every organization, but these are the leading choices:

Cybersecurity Essential askmeidentity## My recommendation by scenario

• National infrastructure, utilities, financial services, government, or highly regulated environments: Choose CyberArk if you need the deepest controls, extensive auditing, and complex hybrid infrastructure support.
• Critical infrastructure with many vendors, contractors, or remote administrators: Consider BeyondTrust, especially where third-party remote access and endpoint privilege control are major concerns.
• Organizations that need strong PAM but want quicker deployment and simpler operations: Consider Delinea.

For critical infrastructure specifically, I would prioritize these capabilities

1. Zero standing privilege

• Avoid permanent admin rights.
• Grant access only when needed and for limited durations.

2. Session monitoring

• Record privileged sessions.
• Capture commands, approvals, and user activity.

3. Break-glass controls

• Maintain emergency access accounts with strict monitoring and post-use review.

4. OT/ICS compatibility

• Ensure support for industrial systems, network devices, jump hosts, and legacy platforms.

5. Integration with your SOC

• Send privileged activity logs to tools such as SIEM, SOAR, and identity governance platforms.

If your environment is truly critical infrastructure, my default shortlist would be:

1. CyberArk — strongest enterprise-grade PAM choice
2. BeyondTrust — strongest when endpoint and vendor access are major risks
3. Delinea — strongest balance of capability and operational simplicity

The final selection should depend on your environment: IT only vs OT/ICS, number of privileged accounts, cloud footprint, regulatory requirements, and whether you need vendor access management.

There is no single "best" Privileged Access Management (PAM) solution for every organization, because the right choice depends heavily on your infrastructure makeup (cloud vs. on-prem), size, and specific security workflows. However, the enterprise market is led by a few powerhouse platforms , each tailored to different operational needs:

• CyberArk: The gold standard for massive, complex, and legacy enterprise environments. It offers unmatched depth in credential vaulting, session brokering, and broad system support (including mainframe and industrial/OT environments). Best for: Large enterprises with diverse, highly complex, or legacy critical infrastructure that need deep, granular control.
• BeyondTrust: Exceptional at combining infrastructure PAM with endpoint privilege management (removing local admin rights). It also shines in secure remote vendor access and session monitoring. Best for: Windows-heavy environments, organizations aiming to eliminate endpoint admin rights simultaneously, and teams managing third-party vendor access.
• Delinea (Secret Server): Known for being developer- and administrator-friendly with a faster, easier deployment curve than heavy legacy vaults. It offers robust password management and vaulting without the steep complexity curve of CyberArk. Best for: Mid-to-large enterprises looking for rapid time-to-value and a more intuitive user experience.
• Duo / Microsoft Entra Privileged Identity Management (PIM): If your critical infrastructure is heavily cloud-native (Azure/Microsoft 365 or hybrid AD), native cloud identity governance offers just-in-time (JIT) access without heavy on-prem infrastructure overhead (though it lacks deep legacy session recording). Best for: Cloud-first or Microsoft-centric organizations looking for just-in-time elevation.

To help narrow down which platform fits your environment, tell me:

• Is your critical infrastructure on-premises, cloud-native, or a hybrid mix?
• Do you need to support legacy systems, mainframes, or OT/IoT equipment?
• Is endpoint privilege management (removing local admin rights on employee laptops/servers) a priority?

If you mean privileged access management (PAM) for critical infrastructure—especially environments spanning IT, OT/ICS, servers, network devices, cloud, and third-party vendors—my first choice would be BeyondTrust, with CyberArk as the strongest alternative for very large, highly regulated enterprises.

My recommendation

Why BeyondTrust gets my nod for critical infrastructure: its platform specifically addresses IT/OT environments, including segmented and non-routable OT networks. Its Privileged Remote Access can provide time-bound, attributable access for operators, contractors and vendors, while Password Safe handles privileged credentials and session monitoring. It also supports session recording, keystroke logging and audit reporting.

For critical infrastructure, I'd prioritize these capabilities over simply having a good password vault:

1. Just-in-time / least-privilege access — eliminate persistent administrator privileges.
2. Secure third-party/vendor access — particularly important for ICS/SCADA maintenance.
3. Full session recording and monitoring — know who accessed what, when, and what they did.
4. OT/ICS segmentation support — access shouldn't require flattening your network architecture.
5. Automated credential rotation and vaulting — including service/shared accounts.
6. Strong MFA and approval workflows.
7. Centralized audit evidence for investigations and regulatory requirements.
8. Integration with SIEM/SOC tooling so suspicious privileged activity can be detected in real time.

BeyondTrust explicitly positions its critical-infrastructure offering around IT/OT resilience, secure remote access, segmented OT networks, centralized auditing, and frameworks including NERC CIP and IEC 62443.

When I'd choose CyberArk instead

I'd lean toward CyberArk if your organization is extremely large, has complex identity domains, or places exceptional weight on deep privileged-identity governance and compliance/audit capabilities. Current industry comparisons continue to put CyberArk, BeyondTrust and Delinea among the leading enterprise PAM choices.

Bottom line: Critical infrastructure with substantial OT and vendor access → BeyondTrust. Massive enterprise with exceptionally complex PAM/compliance requirements → CyberArk. Strong PAM needed with a simpler deployment/operations model → Delinea.

If you tell me whether you're securing energy/utilities, manufacturing, transportation, telecom, data centers, or government infrastructure, I can give you a much more specific BeyondTrust vs. CyberArk vs. Delinea architecture recommendation, including the controls I'd deploy.
