Universal SSH Key Manager

SSH Communications Security Corporation is a publicly traded Helsinki-based company founded in 1995 by Tatu Ylönen, inventor of the SSH protocol. With around 110 employees and over 3,000 customers, it builds products around SSH, including Tectia SSH, CryptoAuditor, and the Universal SSH Key Manager (USSHKM). SSH remains ubiquitous for network encryption, authentication, remote administration, automated processes, and secure file transfer across Unix/Linux servers, mainframes, embedded devices, and workstations. SSH keys are central to these workflows because they are stronger and more convenient than passwords.

A core enterprise problem is that SSH lacks a centralized authority for key generation, distribution, and revocation. Organizations often leave these responsibilities to end users, resulting in uncontrolled key sprawl across servers, devices, and workstations. This makes it difficult to understand who has access to what, revoke access reliably, and prevent key reuse or weak/compromised keys—creating exposure to hacking, insider threats, and compliance failures. Traditional IAM solutions typically do not govern SSH keys, and manual management at scale is impractical and risky because revoking the wrong key can disrupt critical processes.

USSHKM addresses this with a centralized, automated, non-intrusive platform delivered as a virtual appliance, deployable without changing existing SSH infrastructure. It supports many operating systems, SSH implementations, and key types, often operating agentlessly (except typically on Windows). Its capabilities span continuous discovery of keys and trust relationships, monitoring with audit trails, reports and SIEM integration, remediation actions like removing unused keys and renewing weak ones, and policy-based lifecycle management plus configuration compliance and auto-reversion. An optional user portal and integrations (AD/LDAP, REST API, ticketing) enable controlled self-service, approvals, time-bound access, and end-to-end auditability. While not a full EKM suite, it provides comprehensive SSH key infrastructure management.

• SSH Communications Security Corporation is a publicly traded company based in Helsinki, Finland.
• The company was established in 1995 by Tatu Ylönen, the inventor of the SSH protocol.
• SSH Communications Security has around 110 employees and over 3,000 customers worldwide.
• Universal SSH Key Manager is supplied as a virtual appliance for various hypervisors.
• Multiple instances of Universal SSH Key Manager can be deployed in parallel for horizontal scaling or high-availability failover.
• The product supports numerous open source and commercial SSH implementations across Linux/Unix, mainframes, Windows/Linux workstations, and embedded network devices.
• For most supported platforms except Windows, the system can operate agentlessly without installing software on targets.
• The solution provides discovery, monitoring, remediation, and management as its four major functional areas.
• Universal SSH Key Manager can connect directly to Active Directory or LDAP and provides a REST API for integration.
• The product can integrate with ticketing systems to connect SSH access requests to existing workflows.

• “Unfortunately, as opposed to traditional public key infrastructure, SSH does not define a central authority for generating, distributing and revoking keys, and most organizations leave these functions to end users.”
• “With time, this has led to uncontrolled proliferation of keys spread across a large number of servers, devices and workstations, which makes it increasingly difficult to keep track of them, control who has access to where and revoke previously granted access rights.”
• “Manually managing thousands or even millions of SSH keys is not an option even for the largest companies with dedicated IT teams.”
• “Additionally, there is always a risk of disrupting a critical business process by accidentally revoking the wrong key.”
• “No changes in existing SSH infrastructures are needed – the product is designed to be non-intrusive and not to affect existing business or IT processes.”
• “More importantly, the process allows the discovery of trust relationships between keys, and the determination of which keys may be orphaned or rogue ─ giving their owners unauthorized access to critical systems.”
• “Universal SSH Key Manager provides a complete audit trail for all SSH-related activities mapped to systems, applications and user identities.”
• “Policy violations are detected and reported in real time.”
• “This ensures that newly provisioned access is compliant with corporate security policies from start to finish and leaves a complete audit trail.”
• “Although Universal SSH Key Manager is only limited to SSH keys and thus not a full-featured Enterprise Key Management (EKM) solution in the strict sense, it does provide a comprehensive solution to the specific problem of managing decentralized key infrastructures, solving multiple security and compliance challenges often overlooked by traditional EKM products.”
