The Identity Stack Builder is an independent decision-support tool for comparing identity verification, fraud prevention, authentication, compliance, and digital identity vendors. It is designed for practitioners who need to understand the market before building a shortlist, not for vendors to buy editorial ranking.
Use the search, capability, geography, compliance, deployment, and market-segment filters to narrow the directory. Capability families include document and biometric verification, passive and active liveness, KYC and AML, fraud decisioning, identity orchestration, digital wallets, authentication, and eIDAS/EUDI-related infrastructure.
A practical shortlist starts with the buyer’s risk, workflow, geography, and integration constraints. Compare several candidates within the same capability family, read each vendor’s available evidence, and then validate current product scope, implementation effort, data handling, support model, and commercial terms directly with the provider.
The directory is useful for market orientation, but it is not a certification, procurement decision, security assessment, or performance ranking. Vendor listings can change, product boundaries overlap, and a capability label does not prove that a feature meets a particular regulatory or operational requirement. Vendor-managed profiles are marked separately and do not determine independent editorial coverage.
Start with the vendor directory as a discovery aid: use filters to find providers that warrant closer review, then open the underlying profile and primary evidence. A matching filter is not proof that a vendor supports a specific workflow, jurisdiction, certification, control, or integration. Confirm claims against current product documentation, contracts, security and privacy materials, independent testing, references, and a scoped technical evaluation. For procurement, record the date of each check, identify assumptions, compare implementation and operating costs, and ask the provider to explain exclusions, fallback paths, data retention, service levels, and change management. Recheck the shortlist before a decision because vendor products, coverage, ownership, and regulatory obligations can change.
