Legacy App SSO

Passwordless SSO for Legacy and air-gapped Applications

Extend your identity platform to air-gapped, legacy, or isolated environments — without rewriting code or compromising security posture.

The Problem

Modern identity platforms support SAML, OIDC, and modern web protocols. But many mission-critical apps still rely on thick clients, mainframes, or multi-step logins that can't be federated. These systems are excluded from IAM, IGA, and PAM coverage—leaving critical security workflows to be executed manually. As a result, organizations face increased risk of data breaches, audit failures, and user error due to inconsistent access processes.

The Solution

Credenti Unify extends your identity platform to legacy, thick-client, and disconnected apps. Users launch these apps directly from their identity dashboard—without entering credentials or taking extra steps. It works across desktops, Citrix sessions, and terminal-based environments. No changes to the apps. No workarounds. Just one consistent login experience for every user and every application.

Where It Matters

Healthcare

Enable secure and fast access to electronic medical records (EMRs), imaging tools, and other clinical systems. Providers can move between shared workstations without repeatedly typing complex passwords.

Government & Defense

Maintain control over access to classified and air-gapped systems. Ensure secure authentication to mainframe, terminal, and legacy systems while meeting compliance mandates.

Manufacturing

Empower operators and technicians with quick tap-to-login experiences for HMI terminals, SCADA systems, and production software running in harsh or time-sensitive environments.

Banking & Insurance

Provide centralized access to AS/400 systems, legacy finance tools, and internal apps that still rely on local passwords or terminal sessions—without compromising security.

Retail & Hospitality

Standardize access for frontline staff who rotate across kiosks, POS terminals, or back-office desktops. Reduce training overhead and password resets.

The Credenti Differentiator


Launch Thick Apps from Identity Dashboards

Give users the ability to launch legacy applications—including terminal-based tools and native desktop software—directly from the same identity portal they use for cloud apps. No switching systems or separate workflows.

No Code Changes Required

Integrate without touching the underlying application. No source code access, APIs, or SDKs required—meaning faster deployments, lower cost, and zero risk to app stability.

Works Offline and in Air-Gapped Environments

Designed for high-security and disconnected settings, Credenti Unify operates without constant internet connectivity. App policies and credential workflows function locally, even in isolated networks.

One Experience for All Apps

Whether it’s a SaaS dashboard or a command-line tool, users get one simple, consistent way to access everything. This eliminates friction, reduces training needs, and improves compliance.

Full Auditability

Track who accessed what, when, and how—even if the application has no native logging capability. Credenti adds centralized logging and access visibility across the most fragmented environments.
