ATO Protect

Identity Impersonation Detection (IID)

A focused verification layer that confirms the person on the other end of a high-risk request is the actual account holder. ATO Protect runs at the moment a help desk gets a call, a password reset begins, or a privileged change is requested.

Entra ID

Identity and Access Management platform

Microsoft's identity and access management platform, formerly known as Azure Active Directory. Entra ID handles directory services, single sign-on, multi-factor authentication, conditional access, and self-service password reset across the Microsoft ecosystem.

  • CategoryIdentity and Access Management
  • MethodPre-registered authentication factors including Email OTP, SMS, security questions, Microsoft Authenticator, and FIDO2 keys
  • Pre-registrationRequired for SSPR
  • PII storedDirectory profile and registered authentication methods
  • Deploy timeTenant configuration, P1 license needed for SSPR
  • Best fitOrganizations standardizing on Microsoft for SSO, MFA, and access governance
Side by side

Where each product lands on what matters most

The two solutions overlap in one place: the moment a user needs to recover an account. Outside of that moment, they do different jobs entirely.

Capability ATO Protect Microsoft Entra ID
Primary job Confirm the person is the account holder during high-risk events Manage who has access to what across the Microsoft ecosystem
Verification method Government-issued ID scan plus live session checks Pre-registered authentication factors
GenAI deepfake handling Catches voice cloning and synthetic IDs at the document layer Relies on factors that GenAI can phish or intercept
SIM swap detection Real-time check on the registered phone number Not native
Man-in-the-middle and replay detection Patented session-level detection Not in scope
User pre-registration None Required for SSPR
PII stored None Directory profile and method registration
App download for users None Microsoft Authenticator for many flows
Help desk impersonation defense Built for it Out of scope
MFA reset for end users Verifies identity directly, then resets Routes to IT admin in most tenants
Pricing model Per-use, modular Tiered licensing across Free, P1, P2, and Governance
Integration footprint Zero-integration POC, optional API for self-service flows Tenant configuration with downstream app federation
Best paired with Any IAM platform, including Entra ID Any layered identity verification
01 The philosophy gap

Credentials and identity answer different questions

Entra ID asks, "Does this person have the right credentials?" That question is the right one for routine sign-in. The platform was built for it, and it does it well. ATO Protect asks a different question: "Is this person the actual account holder?"

The first question can be answered by anyone holding the right factors. Phished credentials pass that test, along with intercepted OTPs, SIM-swapped phone numbers, and method changes pushed through a tricked help desk. The second question requires something the attacker does not have: the real person's government-issued ID, presented in a session that anti-replay logic can verify.

Most successful account takeovers in 2024 and 2025 did not break authentication. They went around it by calling the help desk.

Multi-factor authentication was built to verify credentials. Identity Impersonation Detection was built to verify identities. Both layers matter, and they protect different parts of the same flow.

02 Where they meet

Account recovery is the overlap

The password reset moment is where these two products meet. Entra ID's self-service password reset depends on factors a user pre-registered: a phone number, the Authenticator app, security questions, or an email address. If an attacker has phished those factors or social-engineered the help desk into swapping them, the reset succeeds for the wrong person.

ATO Protect runs identity verification at that same moment using the user's government-issued ID and live session signals. Whoever owns the directory still owns it. ATO Protect adds a check that the person asking is the real account holder.

The University of Connecticut integrated the ATO Protect API into its NetID password recovery process. Students and alumni now skip the help desk queue and recover their accounts using a government ID, and the reset finishes in under a minute.

03 Stacking them together

Most Trusona customers run both

Most organizations using ATO Protect run Entra ID, Okta, or another IAM platform underneath. The IAM stays in place. The user keeps their existing SSO and conditional access policies. ATO Protect sits in front of high-risk events and adds the verification step that the IAM was never built to handle.

Common deployments include the IT help desk, the password reset flow, MFA factor changes, address and direct deposit updates, wire transfer approvals, and HR onboarding interviews. The pattern is the same in every case: the IAM owns identity and access, ATO Protect confirms the person is real before the IAM acts.

Decision guide

When to reach for which

A quick read on which product fits which problem. In practice, most enterprise programs need both.

Reach for Entra ID

You need an IAM platform

Directory services, SSO across cloud and on-prem apps, conditional access policies, MFA enforcement, and identity governance. Entra ID is the foundation that other identity tools layer onto.

Reach for ATO Protect

You need to stop impersonation

Help desk callers claiming to be locked out, password resets that bypass MFA, HR processes, customer service flows, and any moment where an attacker can social-engineer a human into the wrong action.

Run both

You have a real attack surface

Most enterprises do. Run Entra ID for access. Add ATO Protect at the help desk and at every recovery flow that touches a privileged account. The two layers cover different attacks, and neither one replaces the other.
