At the intersection of compliance and technology, one question keeps coming up: „Isn’t a single solution that does everything enough?” The wish is understandable, because anyone setting up a KYC identity verification would love to tick the box and be done with it. But one point that easily gets overlooked is decisive: the most important step in the entire KYC process is identity verification – because it is the only moment in which a company actually comes into contact with the end customer. All other checks run in the background. That is precisely why this step deserves the greatest attention – and why it is in especially good hands with a provider that specializes in it.
KYC Identity Verification
A quick classification: what KYC actually means
KYC stands for „Know Your Customer“. It refers to the obligation to verify the identity of business partners before entering into a business relationship. In Germany, this obligation derives primarily from the Anti-Money Laundering Act (Geldwäschegesetz, GwG). It requires banks, insurers, payment service providers and other companies to identify their customers and to report suspicious activity.
The KYC process is never made up of just a single step. A sound identity verification for businesses typically involves several elements:
- verifying the identity of a person (matching an ID document against the real person)
- AML screening (Anti-Money Laundering, checking for money-laundering risks)
- the sanctions list check
- the PEP check (politically exposed persons, such as politicians etc.)
- in B2B: the KYB check (i.e. Know Your Business – what is this person authorized to do)
These terms are explained further below. For now, only one thing matters: KYC is a bundle of different tasks that demand very different capabilities.
The appeal of an all-in-one approach
The market for KYC software is full of providers promising to cover the entire process from a single source. This includes identity verification, AML screening, various checks, as well as dashboards, reporting and case management. That sounds convenient – and for some situations it is: one contract, one invoice, one point of contact.
As convenient as that is, it is worth taking a closer look at the most demanding building block. Every provider sets priorities – that is a question of focus and resources. A specialist that concentrates all of its expertise on one area can go especially deep there. And identity verification is the most technologically demanding part of the entire process – and at the same time the only one with direct customer interaction.
Why identity verification is the most critical point in KYC
In digital onboarding – taking on new customers without physical contact – everything depends on this one first step. If a forged ID is accepted here, or a genuine person is wrongly rejected, there are real consequences: either a compliance breach occurs, or users switch to the competition.
A good identity verification today must detect forged and manipulated documents, fend off deepfakes and presentation attacks (for example when someone holds up a photo or video instead of their real face in front of the camera), and handle hundreds of document types from different countries. Digital identity verification – also called identity verification – is a distinct, deep technology field involving computer vision, machine learning and continuous adaptation to new fraud patterns.
What is often underestimated: fraud is a dynamic problem. The methods are evolving rapidly – generative AI has drastically simplified the creation of deceptively realistic forgeries and synthetic identities. A provider whose entire business model depends on detection performance continuously retrains its models and hardens them against new attack vectors. This very focus on a single field is a strength of specialized providers.
Just as decisive as security is conversion. Identity verification is precisely the moment at which customers drop off or get stuck if the user experience is not right. If an app has to be downloaded first, many abandon the process early on. And active liveness detection – where users have to turn their head, blink or perform movements on command – feels cumbersome and can cost completions. Passive liveness detection, by contrast, converts significantly better: it checks the authenticity of the person in the background based on a single selfie, without any active participation. Combined with a purely web-based method that runs directly in the browser without an app download, acceptance rises noticeably – and with it the number of completions. Security and conversion are not mutually exclusive: a good identity verification delivers both, and specialists in KYC identity verification – such as the Swiss premium provider PXL Vision – master this (dynamically optimized) balance better than generalists.
Best-of-breed instead of all-in-one
This is where the classic fundamental question comes into play: best-of-breed or all-in-one? „Best-of-breed” means that for each subtask the best specialized provider is chosen, and these building blocks are combined into an overall system. „All-in-one”, by contrast, means sourcing everything from a single provider.
The recommendation is clear, but not dogmatic: for the most sensitive part – identity verification – a specialist should ideally be engaged. The remaining KYC checks can then be handled simply via an API connection through a compliance service provider or a third-party KYC vendor.
Why does this work well? Because AML screening as well as sanctions and PEP checks are, at their core, database comparisons: the check determines whether a person or company is connected to money laundering, appears on official sanctions lists (for example those of the EU or the United Nations), or holds a high political office with an elevated corruption risk. The same applies to KYB, where instead of a person an entire corporate structure including its beneficial owners is examined – likewise via interfaces to commercial and company registers.
All of these checks depend on the quality and timeliness of the data sources – and there are highly specialized data providers for this that can be integrated in a modular way.
How to recognize a good KYC specialist
If the thesis is „take the best specialist”, it is also important to clarify how to recognize one. When selecting identity verification software for businesses, hard criteria count for more than marketing promises.
- Conversion: the technically best verification is of no use if half of the users drop off. What matters – as described above – is a web-based method without a mandatory app, passive liveness detection and as few steps as possible.
- Detection performance in both directions: how reliably are forgeries detected, and how often are genuine users wrongly rejected? Only both figures together paint an honest picture.
- Regulatory suitability and certifications: in Europe, what counts is whether a method is eIDAS-compliant or whether it meets the BaFin requirements for video- or AI-supported identification procedures in Germany – this is the entry ticket into regulated markets.
- Local expertise: locally rooted specialists know the country-specific particularities and cover the full range of documents – from different ID types through e-IDs and health insurance cards to driving licenses – often more reliably than a global provider. „Think global, act local“ is not a contradiction here, but a genuine quality advantage.
- Flexibility: a good specialist can be configured individually, rather than imposing a rigid standard procedure. Verification steps, security level and onboarding flow should be adaptable to the risk profile and target group – a low-risk customer group goes through a lean process, sensitive cases through stricter checks, without the need to switch providers. This configurability often determines whether security and conversion can be optimized together.
- Future readiness: early integration of new documents or methods (eIDs), but also support for older formats that are still valid.
The cost perspective that is often forgotten
One argument in favor of the all-in-one package is its supposedly simpler pricing. What matters, however, is not the list prices but the total cost of ownership over time. An all-in-one package bundles many functions into one price and thus simplifies the calculation. In the best-of-breed model, by contrast, the market price is paid for each building block, with the option to negotiate specifically or to swap out individual building blocks. Against this stands a certain integration effort, which, however, quickly pays for itself. A single fraud case that slips through can cost more than the entire integration.
Data protection and data sovereignty
One point that is often considered too late in customer identification is data protection. Because identity verification processes highly sensitive data – ID images, facial data and biometric features. The GDPR sets clear requirements here. Anyone operating internationally must additionally pay attention to where the data is stored. This too argues for a focused approach: a service provider specialized in processing this data usually has well-thought-out concepts for encryption, deletion periods and data residency, in order to guarantee digital sovereignty for its corporate customers.
What speaks for which path
The objections to the best-of-breed approach must be taken seriously. The most common objection is that several providers mean more integration effort, more contracts and more interfaces. On top of this comes the question of responsibility: with a single provider there is only one point of contact, whereas with several the orchestration has to be handled yourself. For companies with few technical resources and a simple risk profile, an all-in-one package can indeed be the more pragmatic path.
For identity verification itself, however, it is still worth looking at a specialist. Modern KYC software today is largely designed for API integration, so integration is no longer the major project it was ten years ago. Good specialist providers deliver documented interfaces, SDKs and often ready-made connectors to the common data providers. This makes it possible to combine the depth of a specialist in identity verification with the convenience of an end-to-end process chain. And since requirements under the Anti-Money Laundering Act and fraud methods change constantly, a modular setup additionally allows for quick responses.
Two real-world scenarios
A young fintech with a European focus needs a frictionless digital onboarding. A specialist with high conversion pays off immediately here, while AML screening and sanctions list checks are added leanly via API through a third-party provider. An established bank with international business, by contrast, often already has contracts with data providers and internal compliance systems; here a specialized provider for identity verification integrates seamlessly into the existing landscape. In both cases, particular care at the most important step – identity verification – pays off.
A sensible approach in practice
A proven approach begins by precisely determining the risk profile and regulatory obligations: which checks does the Anti-Money Laundering Act prescribe for the specific business model? Next, the most critical building block is filled first, and a true specialist for identity verification is selected – measured by conversion, detection rates and fraud prevention, not by the size of the feature list. Only then follow AML screening, sanctions list checks, PEP checks and, where applicable, KYB via API integration to specialized compliance and data providers – with open interfaces for interchangeable building blocks. A clean audit trail that documents who checked what, when and how is worth its weight in gold during a regulatory audit; otherwise fines loom.
Orchestrate KYC, specialize identity verification
The appeal of a tool that promises everything is understandable. But „Know Your Customer” is not an area in which convenience should be the most important currency. At the point of identity verification, fraud is either prevented or let through – and this business-critical process needs a specialist.
The recommendation is therefore to select the best partner for the actual identity verification, and to integrate the remaining KYC checks via a clean API connection or a suitable third-party provider. As a rule, KYC identity verification unfolds its full strength with a provider that specializes in it, within a well-orchestrated interplay. Those who think this way build a KYC process that remains adaptable tomorrow too.
