Legacy App MFA Without Code Changes
Legacy and on-premises applications often lack modern authentication controls, but replacing or rewriting them is expensive and risky.
Datawiza helps you implement legacy app MFA quickly using a reverse proxy approach, so you can enforce strong authentication without changing application code.
Legacy app coverage
Typical Legacy Application Types
Datawiza helps organizations deploy MFA for customer portals, workforce tools, older line-of-business systems, and critical ERP or CRM apps.
Customer and partner portals
Internal employee tools and intranet apps
Third-party and line-of-business apps
Legacy ERP and CRM systems
With Datawiza, you can protect legacy web and on-prem apps without custom MFA coding. The platform sits in front of your app, enforces MFA or 2FA policies, and grants access only after successful verification.
Fast rollout
Add MFA to Legacy Applications in Hours
Rapid Deployment
Go live in hours, not months, accelerating your project timeline.
Save Costs
Eliminate custom development and reduce maintenance overhead.
Flexible Hosting
Deploy on-premises, in your private cloud, or use Datawiza SaaS.
Meet Compliance
Meet compliance, audit, and cyber insurance requirements like SOC 2, HIPAA, PCI DSS, NYDFS, NIS2, and NIST.
Enhance Security
Modernize authentication with strong MFA and granular access control.
MFA methods
Various MFA and 2FA Methods Supported
- SMS and email OTP
- Authenticator app one-time passcodes, including TOTP from common mobile authenticator apps
- FIDO2 authenticators that support WebAuthn, including security keys and biometrics
- Phishing-resistant PKI Certificate-Based Authentication, including PIV smart cards
Architecture
Reverse Proxy Architecture for Legacy App MFA
Datawiza sits in front of your legacy web app as a reverse proxy. When a user tries to sign in, the proxy triggers MFA and only allows access after authentication is completed.
1. User accesses the app
Users browse to the same app URL. Datawiza Access Proxy intercepts the request.
2. MFA is enforced
Use Datawiza built-in MFA or your existing IdP, including Entra ID, Okta, Google, Ping, Auth0, or Cognito.
3. Access is granted
After MFA succeeds, Datawiza grants access to the legacy web app with stronger security and auditing.
Result: MFA for legacy apps in hours, not months, with no app rewrite, no custom MFA coding, and consistent policy across apps.
Build or proxy
Legacy App MFA vs Custom Code Integration
If your priority is rapid risk reduction without rebuilding core systems, reverse proxy MFA is often the fastest path.
| Criteria | Reverse Proxy MFA | Custom Code MFA |
|---|---|---|
| Deployment speed | Hours to days | Weeks to months |
| Code changes required | No | Yes |
| Legacy compatibility | High | Variable |
| Maintenance overhead | Lower | Higher |
| Policy consistency | Centralized | Fragmented by app |
Common use cases
Why teams add MFA to legacy apps
Meet compliance and audit requirements
Satisfy cyber insurance controls
Reduce credential-based attack risk
Standardize login security across old and modern apps
FAQ
Frequently Asked Questions
Can I add MFA to an app that doesn't support it?
Yes. Datawiza Access Proxy can enforce MFA for legacy and homegrown web apps that do not have native MFA support, without source-code changes or SDK integration.
Do I need an identity provider?
No. Datawiza built-in MFA can challenge users after they sign in with existing credentials and before application access continues. If you already use Entra ID, Okta, Duo, Ping, Auth0, Cognito, or another identity provider, Datawiza can integrate with that MFA flow too.
How long does implementation take?
Initial rollout is often completed in days, depending on routing, policy complexity, identity provider configuration, and how many applications are included in the first phase.
