Vault, PVWA, CPM, PSM, and PSMP come first in CyberArk deployments.

Laying the foundation for CyberArk Sentry: the install order that makes sense

If you’re building a fortress for sensitive credentials, you start with a solid foundation. In the CyberArk world, that foundation is the Vault. It stores the keys, the passwords, the credentials—everything you want secured behind a strong wall. From there, the rest of the stack comes to life in a logical sequence that keeps integration smooth and security tight. Let’s walk through the right order and why it matters.

The install order you can count on

Here’s the straightforward sequence, with a quick snapshot of what each piece adds to the mix:

• Vault: The secure vault that holds credentials and secrets.

• PVWA (Password Vault Web Access): Web interface to access and manage the Vault’s contents.

• CPM (Central Password Manager): Automates password rotation and management inside the Vault.

• PSM (Privileged Session Manager): Secures and monitors privileged sessions.

• PSMP (Privileged Session Manager Proxy): An intermediary that supports various configurations and load scenarios.

Think of it as a ladder. If you skip a rung, the climb gets wobbly. Each piece depends on the stability of the one beneath it, so installing in the right order isn’t a luxury—it’s a necessity.

A closer look at each component and its role

Vault: the foundation that holds everything

The Vault isn’t just a storage box. It’s the secure, centralized store for passwords, keys, and high-sensitivity data. It’s designed to be backed up, audited, and protected with strict access controls. Before you can do much else, you need Vault up and configured with the right policies, backups, and encryption keys. It’s where the entire CyberArk ecosystem finds its home base.

PVWA: bringing access to life

PVWA is the web portal that users, admins, and apps use to reach the Vault. It translates user requests into secure actions inside Vault, enforces role-based access, and presents credentials in a usable, auditable way. Once Vault is ready, PVWA makes it practical—without PVWA, the Vault is a vault no one can access.

CPM: automating safety and rotation

CPM handles password rotation and automated management across the stored assets. With Vault already in place, CPM can be configured to rotate credentials according to policies, schedules, and approvals. This is where you start turning configuration into ongoing security hygiene—reducing the window of exposure and keeping passwords fresh without manual toil.

PSM: safeguarding privileged sessions

PSM is the guardian for privileged access sessions. It provides secure, monitored, and recorded sessions for accounts with elevated rights. Setting up PSM after CPM makes sense because PSM depends on CPM’s managed credentials and Vault’s policy framework to control who can start a session and how it’s observed.

PSMP: the flexible proxy that plays nice in the middle

PSMP acts as a proxy to support various deployment topologies and configurations. It’s the component that helps the system scale and adapt to different network setups or privacy requirements. Install PSMP last because it’s designed to work with the existing PSM layer, routing traffic and enabling fast, reliable connections as needed.

Why this order makes sense from a dependency perspective

Let me explain with a simple metaphor: imagine you’re wiring a new smart home. You don’t start by placing lamps; you install the circuit box first, then the main switches, then the light fixtures, and finally the smart bridge that talks to your phone. CyberArk components follow a similar logic.

• Vault is the data foundation. PVWA needs Vault to exist so it can fetch and manage the secrets. Without Vault, PVWA would have nowhere to reach.

• PVWA must be present before CPM can automate anything meaningful, because you want CPM to operate in a context where credentials and policies are already exposed to a controlled web interface.

• CPM’s job is to rotate and manage secrets consistently. It relies on Vault’s data model and policy definitions, plus PVWA’s accessibility and governance layer.

• PSM builds on the credentials CPM manages. It uses those credentials to establish secure, monitored sessions. If CPM isn’t in place, PSM would be chasing missing secrets or misconfigurations.

• PSMP is the adaptable bridge. It’s designed to support diverse environments, so you install it after the core layers are stable, ensuring it routes traffic to the right places without breaking change prone configurations.

A practical rhythm for deploying

If you’re responsible for rolling this out in a production-ish environment (development, staging, and production alike), here’s a sensible rhythm you can follow:

• Step 1: Vault first. Set up the Vault with foundational security controls—encryption keys, access policies, activity logging, and backup strategies. Validate that PVWA can connect to Vault and perform basic operations.

• Step 2: PVWA goes live. Configure roles, permissions, and access workflows. Ensure authentication methods, approvals, and auditing are wired in. Smoke-test a few credential fetches to confirm end-to-end visibility into activity logs.

• Step 3: Bring CPM online. Define rotation schedules, password lifetimes, and rotation methods. Tie CPM to the Vault’s data model and the PVWA-driven workflows. Run a controlled rotation cycle on a non-critical set of accounts to verify timing, logging, and alerting.

• Step 4: Add PSM. Configure privileged sessions, recording, and policy-based controls. Verify that sessions are captured and that access requests align with security policies. Run a test session to confirm real-time monitoring and post-session review.

• Step 5: Introduce PSMP for scale. Deploy the proxy in the needed network zones or DMZs, set up routing rules, and validate seamless access from client endpoints through PSMP to PSM and Vault via PVWA. Do a final end-to-end sanity check across all components.

Practical tips and common hurdles to avoid

• Don’t skip prerequisites. Some environments need certificate trust chains, DNS resolution, and network whitelisting before you install. A quick audit of these items ahead of time saves a lot of headaches.

• Keep a clear mapping of credentials and policies. When CPM starts rotating, you want to know exactly where each credential lives, who can trigger rotations, and how changes are audited.

• Plan for high availability. In a real-world setup, you’ll want redundant Vault nodes, PVWA instances, and failover paths for CPM, PSM, and PSMP. It’s not glamorous, but it’s essential for reliability.

• Don’t underestimate the logs. Each component churns out logs that matter for security and troubleshooting. Make sure your log retention, searchability, and alerting are baked in from the start.

• Test with representative workloads. Use a few typical use cases—regular credential fetches, a rotation cycle, and a sample privileged session—to confirm the system behaves as expected before you go wider.

• Consider separation of duties in administration. Different teams may own Vault configuration, web access, rotation policies, and session management. Clear ownership reduces friction and improves security posture.

Common pitfalls that tend to trip teams up

• Installing in the wrong order. The dependency chain isn’t just a courtesy; it’s how the components learn to talk to each other. If Vault isn’t ready, PVWA won’t have a solid partner, CPM won’t find its secrets, and PSM won’t have the right credentials to manage sessions.

• Mismatched certificates and trust gaps. Some deployments rely on internal PKI or external certs. If the trust isn’t aligned across all components, you’ll see connection errors and frustrated admins.

• Incomplete access governance. If PVWA permissions aren’t aligned with Vault policies, users may get blocked or, worse, gain broader access than intended. Define a clear policy and test it in a staging environment.

• Overlooking backups and DR. The best security plan includes recovery steps. Verify that Vault backups are current and that you can restore a replica quickly if needed.

• Skipping monitoring. A strong setup includes alerting on failed rotations, suspicious session patterns, and access attempts. Without it, you’re flying blind.

A few extra thought-starters to keep the momentum up

• How would your setup handle a surge in privileged session activity? PSMP can help with load distribution, but you’ll want to monitor performance and scale gracefully.

• What about multi-region deployments? Redundancy isn’t just about hardware—network latency and sync times matter. Plan topology carefully.

• Where do your backups live? Separate, encrypted storage with tested restoration procedures is worth its weight in gold in a tight spot.

• How will changes propagate across environments? A small change in Vault access policy should be tested in a sandbox before it hits production to avoid accidental lockouts.

Putting it all together for a clean, reliable deployment

The five-step sequence—Vault, PVWA, CPM, PSM, PSMP—provides a structured path from a trusted data store to a flexible, secure access framework. It’s not just about installing software in order; it’s about building a coherent security fabric where each layer reinforces the next. When Vault is solid, PVWA becomes predictable; when PVWA is stable, CPM can enforce strong rotation; when CPM is rock-solid, PSM can secure sessions with confidence; when PSM is humming, PSMP can orchestrate access at scale without breaking the flow.

If you’re outlining or refining a CyberArk deployment, use this order as your north star. It’s a pragmatic approach that aligns with real-world security needs, operational efficiency, and ongoing governance. And yes, it’s the kind of sequence that makes your security posture feel like a well-tuned machine rather than a collection of fragile parts.

Final thoughts

Security architecture isn’t a sprint; it’s a careful climb with multiple checkpoints. Starting with Vault and moving step by step through PVWA, CPM, PSM, and PSMP keeps your implementation coherent, auditable, and manageable. It also helps you speak a common language across teams—investigators, engineers, and operators all on the same page.

If you’re mapping out a CyberArk rollout, keep this rhythm in mind. It’s touched with practical nuance, grounded in real-world dependencies, and designed to support a robust, scalable security backbone. After all, in a world where credentials sit at the heart of defense, a well-ordered deployment isn’t just nice to have—it’s the backbone of resilience.
