Public-facing web apps
Require MFA or 2FA before users reach public websites, customer portals, partner apps, and other internet-facing workflows.
MFA for web applications
Add MFA to Web Applications Without Changing App Code
Protect public-facing, external-facing, internet-facing, internal, custom, and legacy web applications with MFA or 2FA enforced by Datawiza Access Proxy before users reach the app.
Start with one high-risk web app, keep the existing login flow intact, and expand the same access-layer pattern across customer portals, partner apps, employee tools, and business systems.
App coverage
Add MFA Where the Application Cannot Easily Add It
Web application MFA projects often involve a mix of public portals, internal tools, custom apps, and older systems that were not designed for modern authentication. Datawiza adds the MFA enforcement point in front of those apps so teams can strengthen access without rewriting each application.
External portals
Protect supplier, vendor, partner, dealer, broker, student, patient, and tenant portals without forcing a full CIAM migration first.
Internal applications
Add MFA to intranet tools, admin consoles, helpdesk apps, reporting portals, and internal line-of-business systems.
Custom and legacy apps
Cover Java, PHP, .NET, Python, IIS, Apache, Nginx, homegrown, and legacy web apps that were not built for native MFA.
ERP and business apps
Use the same access-layer pattern for SAP, Oracle, PeopleSoft, JD Edwards, CRM, ERP, and other business web applications.
Third-party web apps
Place MFA in front of third-party apps and hosted portals when you cannot change the application code or login implementation.
Architecture
MFA Before Web App Access
Datawiza Access Proxy sits in the access path. It checks the user, enforces MFA policy, and forwards approved traffic to the protected web application.

Approved traffic
Trigger: public, external, internal, or high-risk app access.
Policy: MFA by app, path, user, group, or rollout stage.
Evidence: centralized access, MFA, and policy decision logs.
Short demo
See How Datawiza Works
Watch how Datawiza Access Proxy sits in front of existing web applications to enforce MFA before users reach protected apps.
Rollout
Start With One Web App, Then Repeat
The deployment motion is intentionally practical: place the proxy, validate the MFA policy, pilot with a defined audience, and expand across similar apps.
Step 1
Put Access Proxy in front
Route the web application through Datawiza Access Proxy without changing the application source code.
Step 2
Choose MFA and identity policy
Use built-in MFA or connect your existing identity provider when the app should use SSO, SAML, OIDC, headers, or policy signals.
Step 3
Enforce before the app
Challenge users before protected app access, then forward only approved requests to the application.
Step 4
Expand with evidence
Roll out by app, path, user group, risk level, or audience with centralized logs for audit and troubleshooting.
Comparison
Access-Layer MFA vs Coding MFA Into Every App
Custom MFA code can work for a new app. It is usually slower when the portfolio includes existing apps with different frameworks, owners, and authentication patterns.
Decision point
Datawiza Access Proxy
Custom app MFA code
Implementation model
Access Proxy enforces MFA before app access, so the protected app does not need to implement MFA logic.
Each application team implements MFA, changes login/session code, tests edge cases, and owns future maintenance.
Rollout speed
Start with one web app, validate policy, then repeat the same access-layer pattern across more apps.
Rollout speed depends on every app release cycle, framework, authentication pattern, and owner.
Consistency
Use one policy and audit point for public-facing, external, internal, custom, and legacy web applications.
Controls, logs, and user experience can drift across apps as different teams build different MFA integrations.
App coverage
Protect apps that cannot easily support modern MFA, SSO, SAML, OIDC, or WebAuthn on their own.
Older apps, third-party apps, and apps without modern protocol support may require risky rewrites or custom connectors.
Customer proof
“Datawiza is the least friction option to move to a modern MFA. By going with Datawiza and getting this done in a very short time, we were the heroes.”
FAQ
MFA for Web Applications Questions
These are the questions security, IAM, platform, and application teams usually ask before protecting an existing web app.
Can I add MFA to a web application without changing code?
Yes. Datawiza Access Proxy can enforce MFA or 2FA before users reach the application, so the app does not need native MFA support or application-code changes.
Does this work for public-facing and internal web apps?
Yes. The same pattern can protect public-facing, external-facing, internet-facing, internal, custom, legacy, and third-party web applications.
Do we need an identity provider to add MFA?
No. Datawiza has built-in MFA, so using an IdP is not necessary. If you already use Entra ID, Okta, Ping, Auth0, Cognito, Duo, or another IdP, Datawiza can also integrate with it when useful.
Can we roll out MFA app by app?
Datawiza can enforce MFA by application, path, user group, audience, rollout stage, and policy. This helps teams pilot one high-risk app before expanding to more applications.
Can this help with compliance or cyber insurance?
MFA is commonly used to support compliance, audit, cyber insurance, and internal security requirements by reducing password-only access risk and producing centralized access evidence.
