How does MeshaSec handle MFA and SSO authentication?

MeshaSec does not bypass MFA—it natively orchestrates it. You provide test credentials and the engine fulfills MFA/TOTP challenges during the scan just as a real user would.

Can MeshaSec scan modern SPAs like React, Vue, or Angular?

Yes. MeshaSec treats SPAs as dynamic state machines rather than static pages, navigating JavaScript-rich environments natively to map the complete attack surface.

Can DAST tools bypass MFA?

DAST tools do not bypass MFA; they must natively orchestrate it. MeshaSec uses autonomous session management to fulfill MFA/TOTP challenges during the scan process.

Is it safe to share MFA secrets with a DAST tool?

In a dedicated test environment, sharing a TOTP secret with a secure DAST engine is standard practice for achieving full coverage. MeshaSec ensures these secrets are encrypted and isolated.

DAST Scans on MFA-Protected Web Apps: The 2026 Guide

Traditional DAST scanners were built for the static web of the 2010s. They expect a simple username/password combination. When faced with modern dynamic application security testing requirements—including MFA, SSO, or TOTP—these scanners "bounce" at the gate.

Why MFA Breaks Traditional DAST Scanners

Because legacy tools cannot fulfill the secondary challenge (like a TOTP code or an Okta push), the crawler never sees the internal application state. For a modern enterprise, this means up to 90% of the attack surface remains completely untested.

The 3 Pillars of Authenticated Discovery

Native Orchestration:The DAST engine must behave like a browser, handling redirects to Identity Providers (IdPs) like Azure AD or Auth0 natively.
TOTP Seed Support:By providing a TOTP seed, the engine can generate its own 6-digit codes in real-time, allowing it to bypass the "manual bottleneck" of human-provided codes.
Session Continuity:Modern apps often rotate session tokens. The scanner must detect session expiration and re-authenticate automatically without losing its crawl state.

Real-World Evidence Proof

When MeshaSec discovers a vulnerability behind an MFA wall, it doesn't just report a "possibility." It provides the Proof-Based Evidence:

// IDENTITY_VERIFIED :: SESSION_ID_ACTIVE

POST /api/v1/vault/transfer HTTP/1.1
Host: internal.fintech-app.com
Authorization: Bearer eyJhbGciOiJIUzI1Ni...
Content-Type: application/json

{ "amount": "99999", "to": "attacker-id" }

// RESPONSE_CAPTURED :: VULNERABILITY_CONFIRMED

HTTP/1.1 200 OK
{ "status": "success", "tx_id": "83742" }

This proof shows the exact request that bypassed authorization *after* a successful MFA login, allowing developers to fix the root cause instantly.

The Conclusion

Testing behind the identity layer is the single most important factor in a modern AppSec program. If your tool can't handle MFA, you are only securing the lobby of your building while the vault is wide open.

FAQ

Does MeshaSec support Okta and Azure AD?

Yes. We natively orchestrate the SSO handshake for all major IdPs, ensuring your authenticated surface is fully covered.

What if my app uses a custom login flow?

Our engine is built to understand human intent. It identifies login forms and challenges dynamically, ensuring compatibility with even the most complex custom authentication logic.
