What DORA covers and when it started to apply

DORA is Regulation (EU) 2022/2554 on digital operational resilience for the financial sector, better known by the name its acronym comes from — the Digital Operational Resilience Act. Being a regulation, it applies directly: nothing is transposed into Czech law and the obligations follow from the European text itself. Czech law only designates the supervisory authority and sets out the administrative offences.

The subject matter is not banking law but ICT risk. Article 3(5) defines it as any reasonably identifiable circumstance in relation to the use of network and information systems which, if it materialises, may compromise their security and produce adverse effects. The structure follows from that: risk management, detection and reporting of incidents, testing, the supply chain, sharing of information on threats. In practice this is an information security management system with hard, enforceable reporting deadlines and a regulated supply chain.

There are two dates and they get mixed up. The regulation was published in the Official Journal on 27 December 2022 and, under Article 64, entered into force on the twentieth day following publication, that is on 16 January 2023. The same article then provides that it applies from 17 January 2025. Until that day the regulation existed and was in force, but created no enforceable obligations — the two years were a transition period for getting ready.

An editorial trap: on its DORA page the Czech National Bank writes that the regulation entered into force on 17 January 2025, and its news item from the same day is headlined "The DORA Regulation takes effect". This is not a contradiction in substance, only a shorthand for the date of application — with a regulation, entry into force and application are two different things, whereas Czech acts are commonly described as taking effect. If the date is ever disputed, what decides is the wording of Article 64, not the wording on a website.

Who is in scope, who is excluded and who gets a lighter framework

The scope is a closed list. Article 2(1) enumerates the entities under points (a) to (u). Points (a) to (t) are collectively called "financial entities" (Article 2(2)); point (u) covers ICT third-party service providers. That difference in status matters: a provider sits inside the scope of the regulation but is not a financial entity, so most obligations do not reach it directly — they reach it through the contract. The exception is critical providers, who are overseen by the European Supervisory Authorities (see below).

The simplified framework under Article 16 is not a general exemption "for small entities" — it is a named list. It covers small and non-interconnected investment firms, payment institutions exempted under Directive (EU) 2015/2366, institutions exempted under Directive 2013/36/EU in respect of which the Member State has not exercised the option in Article 2(4), electronic money institutions exempted under Directive 2009/110/EC and small institutions for occupational retirement provision. Articles 5 to 15 do not apply to them; instead, the second subparagraph of Article 16(1) imposes eight obligations covering the cyber security minimum (in the list below).

The simplified framework lightens the load elsewhere in the regulation too: entities referred to in Article 16(1) are not subject to threat-led penetration testing (Article 26(1)) and do not have to adopt a separate strategy on ICT third-party risk (Article 28(2)).

A microenterprise, however, is not a synonym for the simplified framework. Microenterprises are not excluded from scope — the regulation merely narrows the requirements for them in a few places, for example in the testing programme (Article 24 and Article 25(3)), in threat-led penetration testing (Article 26(1)) or in the exercise of audit rights at a provider (last subparagraph of Article 30(3)). Everything else applies.

The exclusions in Article 2(3) have six points and one of them is easily dropped. The regulation does not apply to: (a) managers of alternative investment funds referred to in Article 3(2) of Directive 2011/61/EU, (b) insurance and reinsurance undertakings referred to in Article 4 of Directive 2009/138/EC, (c) institutions for occupational retirement provision operating pension schemes which together have no more than 15 members in total, (d) natural or legal persons exempted under Articles 2 and 3 of Directive 2014/65/EU, (e) insurance intermediaries, reinsurance intermediaries and ancillary insurance intermediaries which are microenterprises or small or medium-sized enterprises, and (f) post office giro institutions referred to in Article 2(5), point 3, of Directive 2013/36/EU. On top of that, Article 2(4) allows a Member State to exclude from scope the entities listed in Article 2(5), points 4 to 23, of Directive 2013/36/EU.

The five areas DORA is made of

The regulation splits into five thematic blocks. Their order matches the way they build on one another in practice: first it has to be clear who decides and on what basis, then comes the ability to recognise and report an incident, then verifying that all of it works, and finally the supply chain, which in the financial sector is where most of the real risk exposure sits.

The Czech version of the regulation uses the abbreviation "IKT" where practitioners say ICT. It is the same thing, but anyone searching the Czech official text has to type IKT — a query for ICT returns nothing there.

When an incident is major and the deadlines for reporting it

The duty to report major ICT-related incidents follows from Article 19, but the regulation itself does not say when an incident is major or what has to be sent by when. Classification is governed by Delegated Regulation (EU) 2024/1772, the deadlines by Delegated Regulation (EU) 2025/301. Without those two texts the reporting duty cannot be met.

Under Article 8(1) of Regulation 2024/1772 an incident is major where critical services are affected and, at the same time, at least one of two conditions is met: either the materiality threshold for the data losses criterion under Article 9(5), point (b), of that regulation is reached — that is, there has been successful malicious unauthorised access to network and information systems which may result in data losses — or two or more of the other materiality thresholds are reached. A single threshold met, malicious access aside, therefore does not lead to a report.

Article 5(1) of Regulation 2025/301 sets three deadlines. The initial notification as soon as possible, in any case within 4 hours of classifying the incident as major and no later than 24 hours after the entity became aware of it. The intermediate report no later than 72 hours after the initial notification, even where neither the status nor the handling has changed. The final report no later than one month after the intermediate report, or after the last updated intermediate report.

Where the entity became aware of the incident earlier but only assessed it as major later, the 4 hours for the initial notification run from the classification (Article 5(2)). A postponement over weekends and public holidays does exist, but not for everyone — and this is where the costliest mistake is made, because the blanket version of the rule is, for a bank, a recipe for missing the deadline. The bullets below cover both: first the materiality thresholds, then the three variants of the postponement.

In the Czech Republic, reports go to the Czech National Bank through the SDAT collection system, on the return for reporting a major incident; according to the ČNB the form is in English only. An entity that misses a deadline has to notify the authority under Article 5(3) of Regulation 2025/301 without undue delay, at the latest within the deadline concerned, and explain why. Where an incident has an impact on the financial interests of clients, the entity informs them without undue delay under Article 19(3) of DORA. Reporting may be outsourced under Article 19(5), but responsibility for fulfilling it stays with the financial entity — this can be treated as an ordinary incident management process, only with deadlines in hours rather than days and with the return prepared in advance; we set it up as part of the incident response plan, not as a separate compliance exercise.

Resilience testing and threat-led penetration testing

Testing is the area where DORA is closest to ordinary security practice. Under Article 24, financial entities other than microenterprises establish a testing programme as part of the ICT risk management framework, follow a risk-based approach and ensure that the tests are undertaken by independent parties, whether internal or external; for internal testing they have to allocate resources and avoid conflicts of interest in the design and the execution of the test. Article 24(6) then sets a hard minimum cadence: at least yearly, appropriate tests of all ICT systems and applications supporting critical or important functions.

What counts as testing is listed in Article 25 — the overview is in the bullets below. Central securities depositories and central counterparties additionally perform vulnerability assessments before any deployment or redeployment of applications and infrastructure components supporting critical or important functions (Article 25(2)).

The top tier is threat-led penetration testing (TLPT) under Article 26. It is carried out at least every three years, but it does not concern everyone — it applies to entities other than those referred to in Article 16(1) and other than microenterprises which are identified for it by the competent authority. The identification criteria are specified by Delegated Regulation (EU) 2025/1190: on one side the impact and systemic nature of the entity, on the other ICT risk factors — the complexity of the architecture, the dependence of critical functions on ICT systems, the number and type of arrangements with providers and the maturity of the ability to monitor the infrastructure and respond in time.

TLPT is not a bigger pentest. Under Article 26(2) it is carried out on live production systems actually used to support critical or important functions, the scope is validated by the competent authority and the defensive team is not told about the test. Where ICT providers fall within the scope, the entity secures their participation (Article 26(3)); where that would risk harming the provider's customers outside the scope of DORA, Article 26(4) allows pooled testing for several financial entities under the lead of one of them.

In the Czech Republic the framework is TIBER-EU, which the Czech National Bank joined in September 2024; in March 2025 it issued the TIBER-CZ Implementation Guide and it acts as the authority for threat-led penetration testing. For entities that are not identified for TLPT there is still a practical lesson in it: the yearly test under Article 24(6) should test the ability to detect and respond, not merely produce output from a vulnerability scanner.

The supply chain and the register of information — the financial entity view

The starting point is Article 28(1), point (a): a financial entity that buys ICT services remains fully responsible at all times for complying with every obligation under the regulation. Outsourcing does not transfer responsibility, it only moves the place where the risk arises. Entities other than those referred to in Article 16(1) and other than microenterprises also adopt and review a strategy on ICT third-party risk, which the management body reviews regularly (Article 28(2)).

Before entering into a contract, Article 28(4) requires the financial entity to assess whether the arrangement covers critical or important functions, whether the conditions for supervision are met, what risks the arrangement brings including a possible increase in concentration risk, to carry out due diligence on the provider and to assess conflicts of interest. Under Article 28(5) it may only contract with providers that comply with appropriate information security standards, and for critical or important functions it has to consider whether the provider applies the most up-to-date and highest quality standards.

Article 28(7) and (8) then require the ability to terminate the contract in listed situations and, for critical or important functions, a documented, tested and regularly reviewed exit strategy, including plans for transition to an alternative provider or back in-house.

The register of information under Article 28(3) is a complete record of all contractual arrangements on the use of ICT services, kept at entity level and at sub-consolidated and consolidated level, distinguishing the arrangements that support critical or important functions. It is not a one-off inventory: a reporting duty, a fixed format and, in the Czech Republic, an annual collection through the ČNB attach to it. The details are in the bullets below.

There is a dated interpretation from the ČNB on how far the register has to reach. In its answers from the webinar on DORA reporting of 27 March 2025, the ČNB said that the implementing standard assumes all ICT service providers, but that at that stage it would treat the inclusion of significant and critical providers — those whose services have a material impact on operational capability, security or continuity — as the minimum acceptable standard. That is a supervisor's interpretation for the first data collection, not the text of the standard — before filing, it is worth checking what the ČNB says about the current collection.

The part for providers: what Article 30 means when you are not a bank

The definition of a provider is deliberately broad and carries no size threshold. Article 3(19) defines an ICT third-party service provider as any "undertaking providing ICT services", and the service itself is defined just as broadly in Article 3(21): digital and data services provided through ICT systems on an ongoing basis to anyone inside or outside the organisation, including hardware as a service and its support through software or firmware updates. The only express carve-out is traditional analogue telephone services.

A three-person software shop supplying a bank with a single microservice is therefore an ICT provider in the same way a hyperscaler is. Direct obligations under the regulation usually do not arise for it. They arise from the contract, because the bank is not allowed to conclude one without the relevant provisions. That is why, since mid-2025, software houses, SaaS and managed service providers have been receiving contract addenda and long security questionnaires — the bank is not ticking a box of its own, it is securing the evidence it needs for Articles 28 and 30 and for the register of information.

Under Article 30(1) the rights and obligations have to be clearly allocated and set out in writing, and the full contract including the service level agreements should sit in a single document available in hard copy or in a downloadable, durable and accessible format. Article 30(2) then lists the minimum every ICT services contract has to contain, and Article 30(3) adds further provisions for the case where your service supports a critical or important function of the bank.

What a critical or important function is follows from Article 3(22) — in short, an activity whose disruption would materially impair the bank's financial performance, or its ability to keep its services and activities running, or its continuing compliance with the conditions of its authorisation. Whether your service is one of them is the bank's call — and in practice you can tell from how tough an addendum you receive.

Two things that can be negotiated. First, Article 30(4) expects the parties to consider using standard contractual clauses developed by public authorities — a legitimate argument against bespoke invention in every addendum. Second, where the financial entity is a microenterprise, the last subparagraph of Article 30(3) allows the parties to agree that the rights of access, inspection and audit are exercised by an independent third party appointed by the provider. The elements a financial entity has to determine and assess when subcontracting ICT services that support critical or important functions are specified by Delegated Regulation (EU) 2025/532 — in practice this means a provider has to know who sits underneath it and be able to evidence it.

Overlap with the Czech Cybersecurity Act

The most frequent question at the boundary of the two rulebooks is whether a bank is under DORA or under Act No. 264/2025 Coll. The answer "under DORA, not under the Cybersecurity Act" is a shorthand that only partly holds.

The mechanism sits in Article 4 of the NIS2 Directive: where sector-specific Union legal acts require essential or important entities to adopt cyber security risk-management measures or to notify significant incidents, and the effect of those requirements is at least equivalent, the corresponding provisions of the directive — including those on supervision and enforcement — do not apply to those entities. DORA is precisely such a sectoral act.

In the Czech implementation it looks like this. The financial market is one of the sectors under the Cybersecurity Act, and Decree No. 408/2025 Coll. defines the regulated services within it — the activity of a credit institution, the operation of a trading venue and the activity of a central counterparty (required by the directive) and, going beyond the directive, the activity of a payment institution and the activity of an electronic money institution.

In the explanatory memorandum to the decree, NÚKIB explains that in matters of security measures, incident reporting and the exercise of supervision these entities will fall under the DORA regime and that only the remaining provisions of the Cybersecurity Act will apply to them, in particular the national instruments. Both authorities confirmed that reading in a joint statement of the ČNB and NÚKIB of 24 June 2026: the DORA requirements on cyber risk management and incident reporting generally take precedence, but this is not a blanket disapplication of the Act. What specifically remains of it is in the bullets below.

A practical view: running the dual regime as two projects does not pay off. The measures are largely the same in both rulebooks; what differs is the reporting, the supervisory authority and the format of the evidence — so one risk assessment and one set of measures can be built and the differences covered by mapping. That is how we do it for providers serving regulated clients in several sectors at once.

Who supervises and what is at stake

The Czech adaptation consists of two acts of 22 January 2025, published on 14 February 2025 and both effective from 15 February 2025: Act No. 31/2025 Coll. on the implementation of European Union legislation in the area of financial market digitalisation (the Financial Market Digitalisation Act) and Act No. 32/2025 Coll., amending certain acts in connection with that implementation and with sustainable finance.

Under Section 9 of Act No. 31/2025 Coll., the competent authority under DORA is the Czech National Bank. It supervises every person subject to obligations or prohibitions under the regulation (Section 10), may impose remedial measures (Section 11) and may exercise the powers under Article 50(2), points (a) to (c), and Article 50(4), points (b) or (c), of DORA (Section 12). Compliance is enforced through coercive fines: up to CZK 5,000,000 individually and up to CZK 20,000,000 in aggregate (Section 14).

One group of providers does not fall under the ČNB. Under Article 31, the European Supervisory Authorities (EBA, EIOPA and ESMA) designate, through the Joint Committee, the ICT third-party service providers that are critical for financial entities, and appoint a Lead Overseer for each of them from among their own ranks. The criteria are in Article 31(2) and are specified by Delegated Regulation (EU) 2024/1502: the systemic impact of a large-scale outage, the systemic character of the dependent financial entities, the degree of reliance for critical or important functions and substitutability.

The inputs for designation come from the registers of information — which is why the register is collected in a structured form every year. The list is published and updated yearly under Article 31(9), and the first one came out on 18 November 2025; a provider not on it may apply for designation itself under Article 31(11). For Czech software houses this is a scenario out of reach — designation targets providers operating across Europe. The penalties for breaching DORA are then set not by the regulation but by the Member State; in the Czech Republic they are in Sections 18 and 19 of Act No. 31/2025 Coll. and are graded by what was breached:

Management responsibility is not framed in DORA as a sanction but as an assigned role: Article 5(2), point (a), puts the ultimate responsibility for managing ICT risk on the management body, and Article 5(4) requires its members to keep up to date through regular training in this area. Article 50(5) further expects Member States to give authorities the power to apply administrative penalties and remedial measures to members of the management body and to other individuals responsible under national law. Minutes of the meeting at which management approved the ICT risk management framework and allocated its budget are therefore a record worth having.

From the text to operations

Resilience shows
in an incident, not in an audit.

The guide describes what the rules ask for. The harder half is the other one: who decides at night that an incident is major, against which criteria, and who sends the initial notification within four hours. We will go through it on your systems, your processes and your people, not on a template.
