Powerful Access Control. Simply Delivered.
Your Legacy Apps Deserve
Modern Security
TAC adds MFA, device posture checks, and continuous validation to any application — without changing a single line of code.
Your most critical apps are your most vulnerable
Every enterprise has them — critical applications built years or decades ago that run core business processes. Thick-client apps. Forms-based login screens. Kerberos-authenticated tools. IoT management consoles.
They can’t support SAML. They can’t do OIDC. They definitely can’t do FIDO2.
These are often your most important applications — and your most vulnerable. They’re protected by basic passwords, maybe IP restrictions, and hope.
Your modern security stack — Okta, Duo, Microsoft Entra — requires applications to support modern protocols. If the app can’t do SAML or OIDC, it’s left unprotected. You’re told to “refactor the application” or “use a gateway” (at additional cost).
Result: Your most critical systems are protected by the weakest security — basic passwords and network access.
TAC takes a different approach
Because TAC is a reverse proxy, it sits in front of your application and handles all authentication and authorization before the user ever reaches the app. TAC can inject:
Any MFA Method
FIDO2, SafeLogin MFA, SMS, OTP, TOTP, push notifications, hardware tokens — choose the method that fits your security posture
Device Posture Validation
OS version, patch level, antivirus status, disk encryption, firewall, domain join — verified before access is granted
Continuous Access Evaluation
Not just at login — throughout the entire session. Compliance lapses mid-session trigger immediate access revocation
Session Management
Session timeout policies, idle lockout, and re-authentication triggers — all enforced at the proxy level
Geolocation & Network Rules
Restrict access by geographic location, IP range, network type, or time of day — regardless of what the app supports
SSO Integration
Users access legacy apps through the same SSO portal as modern apps — one login for everything, no separate credentials
What This Means for Your Organization
Your apps don’t need to support MFA. TAC handles it. Your legacy ERP gets FIDO2 authentication. Your thick-client engineering tool gets device posture checks. Your IoT management console gets continuous access evaluation. Your forms-based HR portal gets push-notification MFA. And you didn’t touch the application.
Security Goes Up.
User Friction Goes Down.
You didn’t touch the application. See how TAC protects your legacy apps with a live demo.
Not “most apps.” Not “modern apps.” Every app.
