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

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.
• Cloud-native environments: Use a combination of cloud-native identity controls (such as Microsoft Entra, AWS IAM, or GCP IAM capabilities) plus PAM/secrets tooling where needed.

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.

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)?

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.

There is no single "best" Privileged Access Management (PAM) solution for critical infrastructure, because the right choice depends heavily on your environment’s complexity, your deployment speed requirements , and your team's operational bandwidth.

Industry analysts consistently place a few enterprise-grade solutions at the forefront, each serving a slightly different organizational profile:

• CyberArk — Best for maximum depth and heavily regulated enterprises. Widely regarded as the heavy-hitter for large-scale operations, CyberArk provides unmatched feature depth in session monitoring, industrial/OT environment support, and credential vaulting. However, it requires a dedicated engineering team, a larger budget, and a longer implementation cycle.
• BeyondTrust — Best for unified endpoint and infrastructure privilege. BeyondTrust excels at balancing traditional credential vaulting (Password Safe) with granular endpoint privilege management and secure remote vendor access. It typically deploys faster than CyberArk and suits diverse hybrid architectures well.
• Delinea — Best for fast deployment and leaner security teams. Formed from Thycotic and Centrify, Delinea focuses on usability and rapid time-to-value. It is ideal if you need production-ready vaulting and UNIX/Linux or Windows privilege management quickly without staffing a massive dedicated PAM administration group.
• StrongDM (part of Delinea/integrated ecosystems) or Teleport — Best for cloud-native, Kubernetes, and DevOps-heavy infrastructure. If your critical infrastructure lives primarily in dynamic cloud environments, containers, and short-lived compute instances rather than legacy on-prem servers, these dynamic access-broker tools use Just-in-Time (JIT) ephemeral certificates instead of clunky old password vaults.

To help narrow down the ideal fit, tell me:

• What does your infrastructure makeup look like (mostly on-prem, multi-cloud, hybrid, or OT/industrial control systems)?
• Do you have a dedicated security engineering team to operate the platform, or do you need something lightweight and fast to deploy?
• Are you primarily trying to solve human administrator access, machine/DevOps secrets , or remote vendor access?

If by critical infrastructure you mean environments such as energy, utilities, transportation, telecom, manufacturing/OT, or other systems where privileged misuse can have operational consequences, my best overall recommendation in 2026 is BeyondTrust—with CyberArk a very strong alternative for large, highly regulated enterprises.

My shortlist

Why I lean BeyondTrust for critical infrastructure: its current critical-infrastructure offering specifically addresses IT/OT environments, segmented and non-routable OT networks, vendor access, time-bound access, MFA, session recording, and auditability. It can also provide outbound-only remote access rather than requiring broad inbound VPN connectivity.

That matters because a critical-infrastructure PAM deployment needs to do more than vault administrator passwords. You ideally want:

• Just-in-time / time-bound privileged access
• MFA and approval workflows
• Credential vaulting and automatic rotation
• Full session recording and command/activity logging
• Secure third-party/vendor access
• OT/ICS and segmented-network support
• Least-privilege endpoint/server elevation
• Centralized auditing and incident investigation
• Integration with your SIEM, ITSM and identity provider

BeyondTrust specifically describes support for segmented OT environments, vendor/partner access, session monitoring, video capture, keystroke logging, and controls relevant to NERC CIP and IEC 62443.

When I'd choose CyberArk instead

Choose CyberArk if your environment is exceptionally large or regulated and your primary requirement is the deepest possible enterprise PAM capability. Independent 2026 comparisons consistently put CyberArk at the top for complex hybrid environments and stringent compliance, although it generally comes with greater implementation and operational complexity.

One important 2026 consideration: CyberArk is now part of Palo Alto Networks, following the acquisition completed in February 2026, so I'd explicitly evaluate the post-acquisition product roadmap, licensing and support commitments during procurement.

Bottom line

For a critical-infrastructure operator, I'd start the evaluation with BeyondTrust, particularly if you have significant OT, contractors/vendors, remote maintenance, or segmented networks.

I'd put CyberArk alongside it in the RFP if you have a large security organization and very demanding compliance/audit requirements. Delinea is worth including if deployment simplicity and operational cost are major considerations.

If you tell me whether your infrastructure is primarily IT, OT/ICS, cloud, or a hybrid, I can narrow this to a CyberArk vs. BeyondTrust vs. Delinea decision matrix with the specific controls I'd require in the RFP.

The single best solution depends on your architecture, but industry leaders for comprehensive Privileged Access Management (PAM) include CyberArk PAM for enterprise-scale vaulting, Delinea Secret Server for streamlined administration, StrongDM / Delinea for zero-trust infrastructure and database access, and Teleport for cloud-native/Kubernetes environments. A best-in-class deployment must feature automated password/credential rotation, just-in-time (JIT) access requests , and full session recording with keystroke auditing.

Core Capabilities to Look For

• Just-in-Time (JIT) Access: Replaces permanent standing privileges with temporary, approval-driven, and context-aware rights that automatically expire.
• Credential Vaulting & Rotation: Securely stores root, superuser, and service accounts in an encrypted vault, programmatically rotating keys and passwords to limit exposure windows.
• Session Isolation & Replay: Employs jump boxes or proxy architecture to broker connections, recording terminal/GUI sessions for real-time threat hunting and forensics.
• Machine Identity Support: Extends automated management beyond human operators to handle DevOps secrets, APIs, and service accounts.

Top Solutions Comparison

To help narrow down the right platform, tell me:

• Is your critical infrastructure primarily on-premises, multi-cloud, or hybrid?
• Do you need to support third-party vendor access or focus strictly on internal engineering teams?

For managing and monitoring privileged access to critical infrastructure, the “best” solution is usually a Privileged Access Management (PAM) platform—but the right choice depends on your environment (on-prem, cloud, OT/industrial, regulatory needs, number of admins, and third-party access requirements). Modern PAM platforms typically combine credential vaulting, automated rotation, just-in-time (JIT) access, session recording, approval workflows, and auditing.

Top PAM choices by scenario

My general recommendation

For critical infrastructure (data centers, production servers, cloud control planes, operational technology, or highly regulated systems), I would usually shortlist:

1. CyberArk — best overall for large, security-critical environments where privileged credentials are a major risk.
2. BeyondTrust — especially if you have many vendors, contractors, or remote administrators accessing sensitive systems.
3. Delinea — if you need strong PAM capabilities with potentially simpler deployment and administration.

Capabilities you should require

A strong PAM implementation should include:

• Privileged account discovery (find unknown admin, root, service, and emergency accounts)
• Credential vaulting and automatic rotation
• Just-in-time access instead of permanent admin rights
• Session recording and monitoring (RDP, SSH, database, cloud consoles)
• Approval workflows for high-risk actions
• MFA and identity-provider integration
• SIEM integration for detecting suspicious privileged behavior
• Service account and machine identity management
• Break-glass access controls for emergencies

If you tell me your environment (e.g., AWS/Azure/GCP, Windows/Linux, Kubernetes, OT/ICS, number of admins, compliance requirements, and whether vendors need access), I can narrow this to a specific recommendation and architecture.

There is no single "best" Privileged Access Management (PAM) solution for every organization, because the ideal choice depends heavily on your infrastructure layout (cloud vs. on-prem vs. OT/ICS), team size, budget, and operational bandwidth.

The industry's leading solutions fit distinct organizational needs:

• • Best for: Large enterprises with dedicated security engineering teams and complex, hybrid, or OT/SCADA environments.
  • Why choose it: It remains the gold standard for depth of vision, vaulting power, and comprehensive coverage across human and non-human identities.
  • The tradeoff: It carries a higher total cost of ownership and requires significant implementation and operational overhead.
• • Best for: Organizations needing a seamless balance between credential vaulting and granular endpoint privilege management across diverse OS environments (Windows, Linux, macOS, Unix).
  • Why choose it: Excellent threat context (via features like their True Privilege Graph) and strong remote/vendor access tools without relying heavy-handed VPNs.
  • The tradeoff: Multiple functional modules can lead to complex licensing structures.
• • Best for: Mid-to-large enterprises looking for a SaaS-first, user-friendly alternative that deploys faster than legacy tools.
  • Why choose it: Highly praised for usability, strong UNIX/Linux support, and streamlined credential management that lowers daily administrative friction.
• StrongDM
  • Best for: Cloud-native, engineering-heavy, and DevOps-centric organizations.
  • Why choose it: Provides clientless, JIT (Just-in-Time) access and deep session replay directly to infrastructure like databases, Kubernetes, and SSH without the clunkiness of traditional password vaults.
• Microsoft Entra ID (PIM)
  • Best for: Organizations deeply embedded in the Microsoft 365 / Azure ecosystem.
  • Why choose it: If you already manage identity centrally through Microsoft, Privileged Identity Management (PIM) provides native, time-based elevation and access controls efficiently.

To help narrow down which option fits your critical infrastructure best, let me know:

• Is your infrastructure primarily cloud-native, on-premises, or a hybrid mix?
• Do you need to protect Operational Technology (OT) / industrial systems , or strictly IT/DevOps environments?
• Roughly how many privileged users and service accounts do you need to manage?

For managing and monitoring privileged access to critical infrastructure, my default recommendation is BeyondTrust Password Safe—with CyberArk as the strongest alternative for very large, highly regulated environments.

Why I'd pick BeyondTrust

For critical infrastructure—servers, network devices, databases, cloud infrastructure, service accounts, SSH keys, etc.—you want more than a password vault. The important controls are:

1. Discover privileged accounts and unmanaged credentials.
2. Vault and rotate credentials automatically.
3. Eliminate standing privilege with just-in-time access.
4. Broker privileged sessions so administrators don't directly handle credentials.
5. Record and monitor sessions in real time.
6. Terminate/pause suspicious activity.
7. Maintain an immutable-looking audit trail for investigations and compliance.

BeyondTrust's Password Safe specifically supports discovery, credential management and rotation, JIT access, real-time session monitoring, session recording, and the ability to pause or terminate suspicious sessions.

When I'd choose CyberArk instead

If you're a large enterprise with a particularly high-risk or regulated infrastructure, I'd put CyberArk at the top of the shortlist. Its depth of PAM capabilities and ecosystem is particularly compelling when you have thousands of privileged accounts, complex hybrid environments, extensive compliance requirements, and sophisticated identity/security operations.

When I'd choose Delinea

Delinea Secret Server is an excellent choice when you want strong PAM without as much implementation complexity. It provides privileged credential vaulting, automated password management, RBAC, proxying, session monitoring/recording, and auditing.

Bottom line:
BeyondTrust Password Safe → best balanced choice for critical infrastructure.
CyberArk → best when maximum enterprise PAM depth is the priority.
Delinea → best when ease of deployment/value matters.

If you tell me whether your infrastructure is primarily AWS/Azure/GCP, on-prem servers, network equipment, Kubernetes, or a hybrid, I can narrow this to a specific architecture and compare CyberArk vs. BeyondTrust vs. Delinea feature-by-feature.
