Drawing the line on who - and what - gets privileged access, from human admins to autonomous AI agents.
Delinea Inc. / San Francisco, California - the identity-security firm forged from two former rivals, photographed in the language it lives by: keys, vaults, and the quiet decision of who gets in.
Most cyberattacks do not begin with an exotic zero-day. They begin with a stolen credential - a password, a key, a token that opens a door it should not. Delinea builds the software that manages those doors. Its category is Privileged Access Management, or PAM: the discipline of vaulting, rotating, and monitoring the credentials that unlock an organization's most sensitive systems.
Headquartered at 221 Main Street in San Francisco, Delinea secures privileged access across hybrid and multi-cloud environments. Its tools discover every account that carries elevated rights - admin, root, service, application - store those secrets in an encrypted vault, rotate them automatically, and record what happens when they are used. The goal is least privilege: give each identity exactly the access it needs, for exactly as long as it needs it, and nothing more.
What makes the moment interesting is who is doing the logging in. The fastest-growing identities on a corporate network are no longer people. They are machines, scripts, and - increasingly - AI agents that request access thousands of times a day. Delinea has spent the last few years reorienting its platform around that shift, so that a non-human identity is governed with the same rigor as a human one.
Delinea did not start from a blank page. It started from a rivalry. Thycotic, founded in 1996, made privileged access simple to deploy and manage - its flagship Secret Server first shipped in 2005. Centrify, founded in 2004, went the other direction, specializing in complex identity systems for large enterprises. For years they competed for the same customers.
In April 2021, TPG Capital brought them together - with minority investments from Insight Partners, Thoma Bravo, and PSP Investments - to form a single cloud identity security vendor. In 2022 the combined company shed the ThycoticCentrify name and became Delinea, a word that echoes "delineate": to draw the line that defines who has access to what.
The rebrand was strategic, not cosmetic. It signaled that Delinea was no longer two vaults stitched together, but one platform. In 2023, Silver Lake acquired a majority stake in a deal valuing the business at roughly $2.2 billion, with CEO Art Gilliland - formerly Centrify's chief executive - continuing to lead.
ThycoticCentrify is now Delinea - a privileged access management leader providing seamless security for modern, hybrid enterprises.

Endpoint privilege management for Windows, Mac, and Linux: application control, least-privilege enforcement, and ransomware protection.
High-speed, platform-agnostic vault for secrets, SSH keys, certificates, API keys, and tokens across applications, databases, and CI/CD toolchains.
Cloud-native platform unifying PAM, identity governance, ITDR, and CIEM with visibility, posture, and control across cloud and SaaS.
Secure session broker for RDP and SSH connections, with recording and automatic credential injection.
Identity governance and administration (IGA) and access-rights management - cloud access orchestration trusted by leading audit and consultancy firms.
Rather than build every capability, Delinea assembled its platform through disciplined M&A - each deal filling a gap: threat detection, governance, then just-in-time access for the AI era.
Added Identity Threat Detection & Response (ITDR) and CIEM - continuous discovery of identity-based threats across cloud and SaaS.
Brought identity governance and administration (IGA) and access-rights orchestration into the platform.
Universal access management with just-in-time runtime authorization - a developer-first model built for the agentic AI era.
PAM is a crowded, high-stakes market. Delinea's most direct rival is CyberArk, the category's largest player, alongside BeyondTrust and One Identity. In secrets management it brushes against HashiCorp Vault, and in the broader identity arena it overlaps with Okta and Microsoft Entra.
Delinea's argument for difference rests on two ideas. First, ease of use inherited from Thycotic - PAM that deploys and runs without an army of consultants. Second, a bet that the future of access is not human. By acquiring StrongDM's just-in-time authorization, Delinea is positioning to govern the moment an identity - person, machine, or AI agent - actually requests access, rather than simply storing its password.
Analysts have taken notice. Delinea was named a Leader in the 2025 Gartner Magic Quadrant for Privileged Access Management, and is cited by Forrester, KuppingerCole, and Frost & Sullivan among market leaders.
Delinea and StrongDM are uniting to redefine identity security for the agentic AI era.
- Delinea, January 2026Delinea is a B2B enterprise software company. Its revenue comes primarily from recurring subscriptions - SaaS and licensed on-premises - sold through a global channel of resellers, managed service providers, and technology partners. Growth is measured in annual recurring revenue: ARR reached roughly $250 million by the end of 2022 with 25%+ year-over-year growth, and the business is estimated near $400 million in revenue today.
The expansion motion is classic platform: land with a core product like Secret Server, then upsell governance, threat detection, and access-orchestration modules across the same customer base. Delinea's expertise is deep and narrow by design - two decades of institutional knowledge, from Thycotic and Centrify, focused on the single question of who should be allowed in.
