On-premises password manager

What is an on-premises password manager?

An on-premises password manager is a centralized password management solution whose server component runs on the company’s own infrastructure – traditionally in your own data center, increasingly also in a private cloud or in your own Azure tenant. The encrypted password databases, user management, and logs thus remain entirely within the responsibility of your own IT team.

Functionally, it delivers the same as a business password manager in general: credentials are stored encrypted in one central place, employees access them through clients, and permissions control who may view and use which entries. The difference from purely cloud-based solutions lies in the architecture: in the SaaS model, the vendor operates the servers and stores the vaults on its infrastructure – with on-premises operation, your IT team does.

This difference matters wherever strict security and evidence requirements apply: whoever controls the infrastructure also controls storage location, access paths, backups, and update timing – and can prove it in audits.

Which companies benefit from an on-premises password manager?

On-premises is not an end in itself. The model makes sense above all for organizations where at least one of these points applies:

• Strict data protection requirements: Companies that want to avoid third-country transfers and take full responsibility for data storage themselves.
• Regulated industries: Organizations whose auditors and clients expect clear statements on storage location and access control.
• Public-sector organizations: Administrations and municipal IT that must keep credentials on their own or municipal infrastructure.
• Industrial companies: Operations that do not want access to production and supply systems to depend on an external cloud service.
• IT service providers and agencies: Teams that manage customer credentials separately, traceably, and under their own control.
• Companies with their own IT infrastructure: If you already run a data center, virtualization, and backups, you integrate password management without a new external component.
• Internal compliance requirements: Organizations whose policies restrict or prohibit outsourcing credentials to third parties.

Advantages of an on-premises password manager

• Data sovereignty: The encrypted databases reside on systems your company controls – not with the vendor and not with the vendor’s subprocessors.
• Control over the infrastructure: Your IT team determines storage location, network access paths, backup strategy, and update windows.
• Centralized user management: Users, groups, and policies are administered in one place.
• Clear roles and permissions: Tiered permissions govern who may view, use, or change entries.
• Secure password sharing: Teams share credentials via shared, encrypted databases instead of by email or messenger.
• Auditability: Logged logins, changes, and admin actions provide reliable answers for audits.
• Integration with your existing IT: Connection to directory services, single sign-on, and MFA prevents duplicate user management; SIEM integration supports centralized log analysis.
• Reduced dependency: Operation does not hinge on the availability or terms of an external cloud service.

On-premises vs. cloud password managers

Cloud password managers are not inherently insecure – for companies without their own infrastructure and without special compliance requirements, they can be an appropriate choice, especially since the vendor carries the operational effort. The question is not “good or bad” but: who should control the company’s most sensitive data?

In short: on-premises is the right choice when control, compliance, and existing infrastructure of your own tip the scales – not because cloud is ruled out in principle.

Password Depot Enterprise Server as an on-premises password manager

The Password Depot Enterprise Server is built consistently for operation in your environment: on-premises in your own data center, in a private cloud at the hosting partner of your choice, or in your own Azure tenant. The solution does not force any external cloud service – data sovereignty remains entirely with you. Developed in Darmstadt, Germany, since 1998, used by more than 100,000 customers.

• Centralized password management: You control users, groups, roles, and permissions centrally on the server – with three permission levels and policies for secure sharing.
• Directory integration: Import users and security groups from Active Directory – across multiple domains of a forest – and synchronize them manually or automatically on a schedule; Microsoft Entra ID and OpenID Connect providers are also supported. The feature overview provides a summary of Active Directory, SSO and MFA.
• SSO and MFA: Kerberos single sign-on plus multi-factor authentication with FIDO2/WebAuthn (e.g. YubiKey) and TOTP.
• Audit logs and SIEM: Logins, changes, and admin actions are logged and exported to your SIEM via syslog (RFC 5424).
• High availability: Real-time mirroring to a secondary server instance – if the primary server fails, the mirror server takes over automatically.
• REST API v2.0: Secrets can be integrated into DevOps pipelines, automation, and internal AI workflows.
• All platforms: Windows, macOS, iOS, Android, Linux, plus browser access via the web client – each connecting to your server, with the same permission logic.

The security architecture is verifiable: AES-256 (FIPS 197), TLS 1.3, a SySS penetration test (12/2025) with the result “no critical or high-severity vulnerabilities identified”, and an ISMS of the manufacturer AceBIT certified to ISO/IEC 27001:2022 (TÜV NORD). Roles, logging, and encryption also support GDPR-compliant password management under Article 32 GDPR.

Typical usage scenarios

• IT departments manage admin and service credentials centrally with roles – instead of shared administrator passwords.
• Companies replace Excel lists and shared browser passwords with encrypted, logged sharing.
• Agencies and service providers separate customer credentials by project and share them traceably.
• Industrial companies keep credentials for production and supplier systems within their own infrastructure.
• Public-sector organizations document password sharing in an audit-proof manner via audit logs.

What companies should look for when choosing a solution

• Deployment model: Does the solution support on-premises, private cloud, and your own Azure tenant – or does it tie you to the vendor cloud?
• Permission and role concept: Can permissions be granted in tiers down to database and entry level?
• Integrations: Active Directory/Entra ID, SSO, MFA, and SIEM integration are standard for enterprise environments – what matters here is shown in our article Password manager with Active Directory, SSO and MFA.
• Logging: Audit logs must be able to answer audit questions – ideally with export to your SIEM.
• Usability: A solution the team does not adopt creates new shadow IT. Clients for all common platforms are a must.
• Scalability: The solution should grow with your user count and organization.
• Support and maintenance: Clarify the update process, maintenance model, and availability of support.
• GDPR and data storage: Where does the data reside, who can access it, and can technical and organizational measures be demonstrated? Explored in depth in our article GDPR password manager for businesses.

Conclusion: control as an architecture decision

An on-premises password manager is the right choice when your company does not want to relinquish control over credentials: data sovereignty, traceable access, and integration with your own IT are an architectural principle here rather than a vendor promise. With Password Depot Enterprise Server you implement this model completely – from operation in your infrastructure to AD/Entra ID integration to audit logs for your evidence obligations.

Frequently asked questions about on-premises password managers

What is an on-premises password manager?

A centralized password management solution whose server runs on the company’s own infrastructure. Encrypted databases, user management, and logs thus remain entirely under the control of your own IT team.

What is the difference between on-premises and self-hosted?

In the narrower sense, on-premises means operation in your own data center on your own hardware. Self-hosted is the umbrella term for any installation you operate yourself – including in a private cloud or in your own Azure tenant. Password Depot Enterprise Server supports all three deployment models; the enterprise perspective is explored in our article Self-hosted password manager for the enterprise.

Is an on-premises password manager more secure than a cloud password manager?

On-premises primarily shifts control to you: your own IT team is responsible for storage location, access paths, and updates, and the password manager causes no third-country data transfers. Whether the overall system is more secure additionally depends on encryption, the role model, and operational quality – criteria you should check with any architecture.

Which companies is an on-premises password manager worthwhile for?

For organizations with strict data protection or compliance requirements, regulated industries, public-sector organizations, industrial companies, and anyone who runs their own IT infrastructure and does not want to outsource credentials to an external cloud service.

Can Password Depot Enterprise Server be operated locally?

Yes. Enterprise Server runs on-premises in your own data center, in a private cloud, or in your own Azure tenant and does not force any external cloud service. You can find details on the Enterprise Server product page.

Does an on-premises password manager support Active Directory?

With Password Depot, yes: users and security groups are imported from Active Directory – including across multiple domains of a forest – and synchronized manually or automatically on a schedule. Microsoft Entra ID and OpenID Connect providers are also supported.

Can an on-premises password manager be used in a GDPR-compliant way?

Yes. Because the data stays on your own infrastructure, the password manager causes no third-country data transfers, and the data protection assessment becomes simpler. With Password Depot, roles, logging, and encryption support the technical and organizational measures under Article 32 GDPR.
