What is Distributed Vaults in CyberArk?

The Distributed Vaults architecture is a high-availability model introduced in CyberArk PAM Self-Hosted to eliminate dependency on a single Vault and ensure continuous access to privileged credentials.

In traditional architecture, everything depends on a single Primary Vault. If it goes down, access to credentials, sessions, and secrets is impacted.

In contrast, Distributed Vaults introduce:

• One Primary Vault

• Multiple Satellite Vaults

• One Primary Candidate Vault

This architecture ensures that privileged access remains available even during outages or regional failures.

---

Why Distributed Vaults is Needed in Modern Enterprises

Large enterprises operate in:

• Multiple countries

• Multiple data centers

• Hybrid cloud environments

• High-latency WAN networks

Without distributed architecture:

• Users face slow authentication

• Session delays occur

• Credential retrieval fails during outages

• Compliance reporting becomes inconsistent

With Distributed Vaults:

✔ Local Vault access reduces latency
✔ High availability across regions
✔ Continuous session access
✔ Automatic failover capability
✔ Reduced dependency on a single data center

This makes it ideal for banking, telecom, and global IT organizations.

CyberArk Distributed Vaults Architecture Overview

Let’s understand the architecture in simple terms.

1. Primary Vault

The Primary Vault is the heart of the system.

Responsibilities:

• Full read and write operations

• Master data source

• Replicates data to Satellite Vaults

• Handles all critical updates

If the Primary Vault is unavailable, write operations stop until failover occurs.

---

2. Satellite Vaults

Satellite Vaults are replica Vaults deployed in different regions.

Key features:

• Provide read services locally

• Serve user and application requests

• Route write operations to Primary Vault

• Continue limited operations during outages

Even during Primary Vault downtime:

• Read-only operations continue

• Audit logs are stored locally

• Session continuity is maintained

---

3. Primary Candidate Vault

This is a special Satellite Vault configured as a standby Primary Vault.

It can:

• Automatically promote itself when Primary fails

• Take over full control of Vault operations

• Ensure minimal downtime

Think of it as a DR-ready Vault with automatic failover capability.

---

Data Replication in Distributed Vaults

CyberArk uses a combination of:

• Asynchronous database replication

• Secure CyberArk Vault protocol

Types of replication:

1. Real-time critical data replication

• Credentials

• Policies

• Account metadata

2. Delayed replication

• Session recordings

• Reports

• Audit files

This ensures performance is not affected while still maintaining consistency.

---

Active-Active Architecture Benefits

Distributed Vaults enable active-active services, meaning multiple Vaults can serve requests simultaneously.

Key Active Services:

1. Application Credential Retrieval

Applications (via CPM/CP) can always retrieve credentials from a nearby Vault.

2. User Credential Retrieval

Users can fetch passwords from the closest Vault without dependency on Primary Vault.

3. Session Management

PSM sessions can continue even if Primary Vault is down.

Supported:

• PSM (RDP & HTML5)

• PSM for SSH

• Remote session continuity

---

Behavior During Primary Vault Failure

When the Primary Vault becomes unavailable:

Satellite Vault enters Read-Only Mode

• Read operations continue

• Write operations are blocked or queued

• Audit logs stored locally

PVWA Behavior

When connected to Satellite Vault:

✔ Users can log in
✔ Users can view passwords
✔ Users can access sessions

❌ Cannot add accounts
❌ Cannot modify configurations
❌ Cannot perform administrative tasks

A warning message appears indicating read-only mode.

---

Password Behavior

• Passwords unchanged since last sync → usable

• Passwords changed during outage → not updated on Satellite Vault → unusable

---

PSM Behavior in Distributed Vaults

Privileged Session Manager (PSM) is partially resilient.

When Vault is available:

• Full functionality

When Primary Vault is down:

• Existing sessions continue

• New sessions may be limited

• Ad-hoc connections disabled

• Ticketing-based sessions restricted

Key limitation:

• Live monitoring is not fully available during outages

---

CPM Behavior (Central Policy Manager)

CPM is highly dependent on the Primary Vault.

• CPM only connects to Primary Vault

• Password rotation stops if Primary Vault is down

• No credential updates during failover

This ensures data consistency and security integrity.

---

Monitoring and Auditing in Distributed Vaults

Auditing is critical in PAM environments.

During normal operation:

• Logs sent to Primary Vault

• Real-time monitoring available

During outage:

• Logs stored locally on Satellite Vault

• Session recordings cached locally

• PTA integration temporarily disconnected

After recovery:

• Logs synchronized back to Primary Vault

• Recordings uploaded

• Audit trail restored

⚠️ Important: Some SSH recordings may not sync back automatically.

---

Authentication Methods Supported

Distributed Vaults support multiple authentication mechanisms:

• LDAP

• CyberArk authentication

• RADIUS

• SAML (only when Primary Vault is available)

👉 Important limitation:
SAML authentication fails if Primary Vault is down.

---

Installation Architecture and Workflow

Deploying Distributed Vaults requires strict sequencing.

Step 1: Pre-Installation Requirements

• Vault prerequisites validation

• PVWA/PSM readiness

• Network latency planning

• NTP synchronization across servers

---

Step 2: Install Primary Vault

• Enable replication

• Set security keys

• Define CA certificates

---

Step 3: Install Satellite Vaults

Maximum allowed:

• 1 Primary Vault

• 5 Satellite Vaults

---

Step 4: Install Components

• PVWA

• PSM

• PSM for SSH

• Disaster recovery preparation

---

System Limitations in Distributed Vaults

Despite its advantages, there are limitations:

Architecture Limitations

• No cloud-based deployments supported

• Cannot revert to Primary-DR architecture after migration

---

PVWA Limitations

• Some dashboards unavailable in read-only mode

• User provisioning blocked during outages

• No session suspension/resume

• Some connectors disabled

---

PSM for SSH Limitations

All Vaults must:

• Use same Certificate Authority (CA)

• Maintain synchronized system time (NTP)

• Use secure replication channels

• Store server keys securely (HSM optional)

---
