TL;DR: Identity verification vendors are converging on similar deepfake claims, but adversarial testing exposes whether fraud controls actually hold under injection attacks, synthetic identities, and edge-case policy gaps, according to Incode. In a market where 75% of enterprise buying decisions happen outside IT, buyer diligence now has to include how the system behaves under realistic fraud pressure.
Editorial analysis by NHI Mgmt Group, based on content published by Incode: “Why Your IDV Vendor Needs Adversarial Testing”.
Key questions
Q: What breaks when IDV vendors are only tested against benchmark conditions?
A: Benchmark-only assurance usually misses the conditions where fraud actually succeeds: policy exceptions, channel-specific thresholds, and software-based manipulation of the capture stream.
Q: Why do deepfake-resistant controls still leave fraud exposure?
A: Because deepfakes are only one attack path.
Q: How do security teams evaluate whether IDV controls are actually working?
A: They should look for evidence from adversarial testing that mirrors current attack behaviour, then confirm that findings were remediated across policy, workflow, and ownership layers.
Practitioner guidance
- Test IDV against attacker behaviour, not vendor claims Require adversarial testing that includes deepfakes, injection attacks, synthetic identities, replay attempts, and manipulated onboarding flows.
- Map exception handling across every identity journey Inventory where the policy differs by transaction type, geography, channel, or business unit, then compare those branches to the controls used in the primary flow.
- Bring security into delegated buying decisions Require security or identity governance review before business units commit to an IDV tool.
Bottom line: The core risk is not lack of IDV controls, but lack of proof that those controls survive realistic adversarial pressure across the full identity journey.

Adversarial testing is becoming the only meaningful trust signal in IDV procurement. Certification, analyst recognition, and feature claims each answer a different question, but none alone proves a control will survive active abuse. The market now has to distinguish between verified capability and verified resilience. For identity programmes, the practitioner conclusion is simple: trust should be earned under attack conditions, not assumed from product documentation.
A few things that frame the scale:
- Gartner predicts that by 2026, 30% of enterprises will consider identity verification solutions unreliable in isolation because of AI-driven attacks.
A question worth separating out:
Q: Should identity governance review sit inside business-led procurement for IDV?
A: No. Business-led speed is useful, but delegated procurement often creates inconsistent assurance levels across departments. Identity governance should review risk acceptance, control thresholds, and exception handling before adoption. Otherwise the organisation ends up with multiple trust standards, which is exactly the condition fraudsters exploit most effectively.
