Before You Compare Vendors

Evaluate digital trust—not just a verification response

Many identity verification providers look similar in demonstrations. Most capture identity documents, compare facial biometrics, perform liveness checks, and return a result through an API.

The real differences appear after implementation—when institutions need broad document coverage, configurable workflows, operational interfaces, fraud prevention, audit evidence, multiple delivery channels, and the flexibility to reuse identity assurance across onboarding, authentication, approvals, and high-risk transactions.

A useful principle

Modern identity platforms should create reusable digital trust—not isolated verification results.

Key Terminology

Industry Terms You Should Know

Before evaluating identity platforms, understand the terms used throughout this guide.

Identity ProofingEstablishing Identity Confidence

The process of establishing confidence that a person is who they claim to be by combining document authentication, biometric verification, liveness detection, trusted data sources, and contextual validation.

Identity AssuranceLevel of Verification Confidence

The overall confidence established through the identity proofing process.

Document AuthenticationDocument Authenticity Validation

Verification that an identity document is genuine, unaltered, and consistent with the security characteristics of the issuing authority.

Liveness DetectionPresence Verification

Technology used to confirm that a real person is physically present while helping detect presentation attacks, manipulated media, and spoofing techniques.

PADPresentation Attack Detection

Capabilities that help identify attempts to deceive biometric systems using photos, videos, masks, synthetic media, or other presentation attacks.

AI Document IntelligenceClassification, Extraction & Validation

AI-assisted processing used to classify identity documents, extract structured data, validate consistency, and reduce manual work.

Geolocation IntelligenceContextual Location Signals

Location and contextual information used to strengthen identity verification, identify anomalies, and support fraud prevention.

Identity Trust ScoreConfigurable Confidence Scoring

A confidence score generated from identity proofing results to support onboarding, risk rating, authentication, and downstream decisions.

Identity OrchestrationReusable Verification & Authentication Workflows

The ability to configure, automate, and reuse identity workflows across multiple business processes throughout the customer lifecycle.

OneView 360Unified Customer Intelligence

A unified operational profile consolidating identity verification, onboarding, compliance, risk assessments, evidence, and customer history.

What Has Changed

From document checks to reusable digital trust

Identity verification has evolved from a point-in-time document check into a foundational layer of digital financial infrastructure. Institutions now need to balance fraud prevention, customer experience, regulatory requirements, operational efficiency, and future expansion within one identity operating model.

Then

Isolated verification services

  • One verification flow designed mainly for onboarding.
  • API results disconnected from operational workflows.
  • Limited document coverage based on current markets.
Now

Reusable identity infrastructure

  • Configurable workflows for onboarding, authentication, and authorization.
  • Identity intelligence connected to OneView 360 and risk processes.
  • Coverage and architecture designed for future products and markets.
Strategic Evaluation Principle

Can the platform adapt to your institution?

Every institution has different customers, products, channels, risk levels, authentication requirements, and growth plans. Your platform should be able to change with them.

Look for configurable capabilities

  • No-code templates for verification and authentication journeys.
  • Policies by product, country, customer type, channel, or risk profile.
  • Web SDKs, mobile SDKs, APIs, and secure hosted verification links.
  • Integration with existing local registries and institutional services.
  • Reusable outputs for onboarding, risk rating, and OneView 360.

Ask vendors directly

  • Can business users configure multiple identity workflows without development?
  • Can onboarding verification and later biometric re-authentication use different templates?
  • Can additional countries and document types be enabled without replacing the platform?
  • Can existing government or local verification integrations be reused?
  • Can the same identity layer support 2FA, approvals, and high-risk transactions?
Modern Financial Infrastructure Framework

Identity verification should support the full trust lifecycle

A modern platform should connect proofing, authentication, evidence, scoring, and reusable workflows instead of returning an isolated pass-or-fail response.

Evaluation Criteria

Characteristics of a modern IDV platform

1

Identity Assurance

Evaluate how the platform combines document authentication, biometric verification, liveness, PAD, and contextual signals—not merely whether it captures images.

2

Global Coverage

Buy for tomorrow's markets. Broad country and document coverage enables new customer segments and international expansion without new vendors or integrations.

3

Identity Orchestration

Look for reusable no-code templates that support onboarding, biometric re-authentication, approvals, 2FA, account recovery, and other trust journeys.

4

Flexible Integration & Delivery

Support APIs, web SDKs, mobile SDKs, and secure hosted links so verification can be embedded or launched externally when direct integration is not available.

5

Open Verification Architecture

Integrate with local registries, trusted verification providers, and services already used by the institution whenever those sources are available.

6

AI-assisted Document Intelligence

Automate classification, extraction, validation, and structured data reuse instead of relying on basic OCR alone.

7

Fraud Prevention & Liveness

Assess whether the platform can detect sophisticated presentation attacks, manipulated media, document fraud, impersonation, and evolving AI-enabled threats.

8

OneView 360 & Trust Scoring

Verification results should become reusable operational intelligence that supports onboarding, risk management, authentication, and future interactions.

9

Operational Platform—not API-only

Evaluate dashboards, evidence, audit trails, notifications, workflow management, configuration, and maintenance—not only the API response.

Identity Orchestration

Digital trust should be reusable across business processes

A modern platform should support different verification and authentication templates for different operational needs.

01

Customer Onboarding

  • Digital customer onboarding
  • Business onboarding
  • Additional or periodic identity verification
02

Authentication & Account Security

  • Biometric re-authentication
  • MFA and 2FA
  • Password reset and account recovery
  • Phone and email OTP verification
03

Customer Authorization

  • High-risk transaction approvals
  • Customer confirmations and sensitive profile changes
  • Electronic contracts and e-signature with identity verification and 2FA
  • Digital agreement approvals
04

Operational & Employee Processes

  • Employee authentication and approvals
  • Internal workflow approvals
  • Privileged access verification

The same identity layer should support every trust interaction

Onboarding, authentication, authorization, and approvals should use one configurable identity platform rather than separate point solutions.

From Buying Software to Buying Outcomes

Buy digital trust infrastructure—not another verification API

The true cost of identity verification extends far beyond the price per verification. API-only services can leave institutions responsible for building user journeys, workflows, dashboards, evidence management, audit trails, notifications, orchestration, and long-term maintenance.

Evaluate the complete operating outcome

1

Lower integration and maintenance effort
Reduce the IT work required to launch and evolve identity programs.

2

Better customer completion
Use secure, intuitive experiences across web, mobile, and hosted journeys.

3

Future-ready coverage
Expand products, customer segments, documents, and markets without replacing the architecture.

4

Reusable operational intelligence
Connect trust scores, evidence, and identity history to onboarding and risk management.

Key Takeaways

If You Remember Only Three Things

1

Identity verification establishes digital trust.

Evaluate the confidence, security, and operational context created by the platform—not only whether a document passes.

2

Buy for tomorrow—not only today.

Coverage, delivery channels, and open architecture should support future products, customer segments, documents, and markets.

3

Digital trust should be reusable.

Identity proofing, trust scores, OneView 360, and orchestration should support onboarding, authentication, approvals, and risk management.
