A fintech trying to close a contract with a bank, insurer or public administration in Europe increasingly faces a security questionnaire asking about its cybersecurity program, certifications, incident response procedures and controls over its technology supply chain. This is not bureaucracy: it is the direct consequence of institutional buyers of fintech services being themselves obligated under DORA and NIS2 to verify the operational resilience of their technology providers.
For fintechs, this creates a new dynamic: regulatory compliance is no longer just a legal requirement managed by the legal team, but a commercial asset the sales team can use to unlock enterprise clients, shorten investor due diligence cycles and differentiate in public tenders. Done right, compliance sells.
But before taking advantage of that opportunity, the regulatory map needs to be understood with precision, because for European fintechs that map includes both NIS2 and DORA, and confusing the two is costly.
Which fintechs fall under NIS2 and which under DORA
DORA (Digital Operational Resilience Act) applies to financial entities regulated under European sectoral legislation: credit institutions, investment firms, payment and electronic money institutions, crypto-asset service providers (under MiCA), fund managers, insurers and, as a specific category, third-party ICT providers deemed critical for the financial sector. If a fintech holds a regulatory license in any of these categories, DORA is its primary digital operational resilience framework.
NIS2 applies to fintechs that do not fit within the DORA perimeter or that provide digital infrastructure services to the financial sector without themselves being regulated financial entities: payment infrastructure providers, banking-as-a-service (BaaS) platforms without their own license, financial software vendors, cloud infrastructure for the sector or financial data service companies. For these, NIS2 establishes the cybersecurity framework.
There is a third scenario: fintechs holding a regulated entity status (and therefore falling under DORA) that simultaneously provide infrastructure services to other financial entities. In that scenario, NIS2 obligations on digital supply chain security apply to their buyers and are passed down to commercial contracts as requirements the vendor (the fintech) must be able to meet and demonstrate.
For a broader view of how NIS2 applies across Europe to different sectors, including financial services, it helps to understand the reference framework before analyzing each company’s specific case.
The requirements NIS2 imposes on the fintech sector
For fintechs that fall directly under NIS2, the obligations of Article 21 of the directive include:
Documented cybersecurity risk management. Having technical controls in place is not enough: there must be a formal process for identifying, assessing and treating risks, kept up to date, with evidence demonstrating the organization makes informed decisions about the risks it accepts. For a fintech SaaS, this includes specific risk analysis of cloud dependencies, third-party API integrations and exposure to software supply chain attacks.
Supply chain security. Fintechs depend on cloud providers, payment gateways, KYC/AML vendors, data platforms and dozens of external integrations. NIS2 requires those dependencies to be mapped, assessed from a risk perspective, and contractually managed with explicit security requirements.
Incident management and notification. Formal detection and response processes, with the obligation to notify the national CSIRT within 24 hours for early warnings and 72 hours for formal notification when a significant incident occurs. For a fintech, a “significant incident” includes any service disruption impacting financial clients, data breaches and compromises of critical systems.
Access controls and continuity. MFA for access to critical and remote systems, identity lifecycle management, and service continuity plans addressing cyberattack scenarios with defined recovery times.
For fintechs looking to align NIS2 with an auditable certification, the comparative analysis on ISO 27001 vs SOC 2 for European companies helps decide which certification produces more value depending on the target client profile.
The NIS2-DORA convergence: where they overlap
Although NIS2 and DORA have distinct scopes, their requirements overlap significantly in the areas of ICT risk management, incident management and security of third-party technology providers.
That overlap has an important practical consequence for fintechs with clients in the regulated financial sector: buyers under DORA are obligated to apply operational resilience requirements to their critical technology providers (which includes many fintechs). DORA calls this “third-party ICT risk” and requires financial entities to monitor the robustness of their technology provider controls. For detail on how DORA specifically manages compliance in the fintech context, the article on DORA and fintech compliance analyzes the regulation’s specific obligations.
What this means commercially is that a fintech able to demonstrate NIS2 controls has a ready answer for the DORA due diligence questionnaires of its institutional clients. The two regulations, rather than being a double burden, can be managed with a single security program that produces evidence valid for both frameworks.
Opportunities: how NIS2 becomes competitive advantage
Here is the angle that few fintechs have yet exploited.
Shortening the enterprise sales cycle. Due diligence processes at large banks, insurers and public administrations for onboarding a fintech vendor can last between three and six months, with security questionnaires running to hundreds of questions. A fintech that can answer those questionnaires with documentation from a certified or auditable NIS2 program reduces that cycle to weeks. Time is money, and in B2B enterprise sales the closing time determines the cost of acquisition.
Unlocking business with regulated entities. Since DORA entered into force, many banks and insurers have tightened their technology vendor onboarding processes. A fintech without a documented cybersecurity program is being disqualified in the pre-qualification phase before the commercial team has a chance to present the proposal. NIS2 compliance is the entry ticket to those conversations.
Trust signal for investors. From Series A onwards, European institutional investors are increasingly including regulatory compliance audits in their due diligence. A fintech with ISO 27001 or a documented NIS2 program validates to the investor that regulatory risk is managed. It is an argument that reduces perceived risk and can impact valuation.
Differentiation in public tenders. Public administrations contracting fintech services (payment processors, subsidy platforms, collection systems) are including cybersecurity requirements as award criteria. A fintech that already has the program in place does not need to build it under pressure for each tender.
Foundation for expansion to demanding European markets. Germany, the Netherlands and the Nordic countries have markets with institutional buyers who are very demanding on compliance. A Spanish or Latin American fintech looking to scale to those markets needs to demonstrate security controls equivalent to local standards. NIS2 is the common regulatory language that facilitates that conversation.
The 4 most relevant risks for fintechs under NIS2
The risk profile of a fintech is different from that of a hospital or a logistics operator. The most relevant attack vectors are:
- API and integration compromises. Fintechs live on APIs: Open Banking, payment gateways, market data providers, digital identity. Each integration is a potential lateral attack channel. Attacks on financial service APIs have grown exponentially since the mass adoption of PSD2 and Open Banking.
- Fraud enabled by poor cybersecurity. Unlike other sectors, in fintech a credential compromise or a hijacked session does not only generate a security incident: it generates direct financial losses for clients. A fintech’s reputation can be destroyed in hours if a security incident results in fraud against its users.
- Concentrated cloud infrastructure dependency. Most fintechs operate on AWS, GCP or Azure, with dependencies on specific managed services (databases, message queues, identity services). A disruption in that concentrated infrastructure can paralyze the service with no technical recourse from the fintech. NIS2 requires contingency plans covering even those scenarios.
- Software supply chain risk. Fintechs integrate hundreds of open source libraries and third-party SDKs. A software supply chain attack (such as the XZ Utils incident in 2024) can introduce vulnerabilities into a fintech’s product without its engineering team detecting it. NIS2 requires vulnerability management processes that include monitoring software dependencies.
How to build a NIS2 compliance program for a fintech
The most efficient entry point for a fintech is combining NIS2 compliance with ISO 27001 certification. Although they are not the same requirement, ISO 27001 provides the management structure that NIS2 assumes already exists, and the certification is the most universally recognized evidence by European institutional buyers. For startups and fintechs in early growth stages, the article on ISO 27001 certification for EU startups provides a reference framework for approaching certification with limited resources.
The minimum viable program for a fintech under NIS2 includes: information asset and critical system inventory (including all cloud and third-party dependencies), risk assessment with business-specific fintech scenarios, management-approved security policies, access controls with MFA and identity lifecycle management, documented vulnerability management and patching process, and incident response protocol with NIS2 notification deadlines already established.
For fintechs classified as essential or important entities working with DORA-obligated clients, the program must also include the ICT third-party dependency map with criticality assessment, and documentation those clients may request in vendor audits.
How PrivaLex helps
PrivaLex works with fintechs at different maturity stages: from startups that need to build the cybersecurity program from scratch to open the enterprise market, to established fintechs that need to formalize and document controls that already exist but are not in a demonstrable state before auditors or institutional buyers.
The starting point is a gap analysis identifying what NIS2 requires (and whether DORA also applies), what already exists in the organization and what remains to be built. The result is a roadmap with priorities ordered by impact, a documented program with auditable evidence and, where appropriate, support through ISO 27001 certification.
For fintechs wanting to understand how NIS2 applies specifically to their business model, the guide on NIS2 for SaaS companies covers scope criteria and obligations with a focus on the digital business model.
Conclusion
NIS2 for European fintechs is not just another compliance requirement: it is the cornerstone of a trust program that determines who they can do business with and at what speed. Fintechs treating it as a regulatory burden are missing concrete commercial opportunities against competitors that have already turned it into a sales argument. Compliance done well does not block growth: it accelerates it.

Frequently Asked Questions
It depends on the entity type. If the fintech holds a license as a payment institution, electronic money institution, investment firm or another category regulated under European financial legislation, DORA is its primary digital operational resilience framework. If the fintech is a technology or infrastructure provider to the financial sector without itself being a regulated entity, it may fall under NIS2. In some cases both apply simultaneously or indirectly (clients under DORA pass DORA requirements down to their fintech providers). Determining the exact fit requires analyzing the business model, licenses held and services provided.
NIS2 applies from medium enterprise thresholds: at least 50 employees or more than 10 million euros in annual turnover. Micro and small enterprises generally fall outside the direct scope of NIS2, though they may fall within it if they provide critical services designated as such by national authorities or if they are providers of specific digital services mentioned in the directive’s annexes. Additionally, even fintechs not directly in NIS2 scope receive security requirements indirectly from their enterprise clients who are obligated.
For a fintech of between 50 and 200 people that already has basic technical controls in place (MFA, access management, backups), building the complete NIS2 program with auditable documentation takes between three and six months. If the fintech wants to simultaneously obtain ISO 27001 certification, the typical timeline is six to twelve months. For fintechs starting from scratch on security documentation, the timeline may be longer. What extends the process most is not technical implementation but formal documentation: approved policies, risk assessment, reviewed vendor contracts and training records.
The evidence most valued by institutional buyers is: ISO 27001 certification issued by an accredited body (the gold standard for third-party evidence), the latest security audit or penetration test report, the management-approved security policy, the incident register for the past year with the response process documentation, and the third-party dependency map with controls over critical vendors. DORA due diligence questionnaires from banks and insurers typically request exactly those documents.
Yes, if the fintech exceeds the size thresholds and provides services in sectors covered by NIS2. The fact that customers are end consumers rather than institutions does not exempt from NIS2 obligations. Additionally, if the fintech processes payment or financial data of a significant number of people, the scale of risk to data subjects in the event of an incident triggers the notification threshold under both NIS2 and GDPR. For B2C fintechs, the cybersecurity program is also a trust argument for users themselves.
NIS2 requires notification of “significant incidents”, defined as those causing or likely to cause a severe operational disruption or significant financial losses for the entity, or affecting other natural or legal persons by causing considerable material or immaterial damages. For a fintech, this includes payment service disruptions impacting clients, financial data breaches, credential compromises with unauthorized account access and ransomware attacks on production systems. The interpretation of “significant” is one of the most debated aspects of implementation and it is worth having pre-defined criteria before an incident occurs.
