Where this stands
The state of play
- In application since
- 17 January 2025 — regulation (EU) 2022/2554
- Register of information
- Annual. The 2026 collection ran through the CSSF eDesk portal from 11 February to 31 March 2026, on a 31 December 2025 reference date
- Third-country branches
- Branches of credit institutions headquartered outside the EU were invited to submit by 30 June 2026 on a best-effort basis, as a rehearsal for the first hard deadline in March 2027
- Quality control
- ESA checks ran through April 2026 against more data fields than the previous year — a register accepted last year can be rejected this year
- Incident reporting
- Circular CSSF 25/893 — classification and notification of major ICT-related incidents, and voluntary notification of significant cyber threats, through eDesk
- Third-party services
- Circular CSSF 25/882 is the Luxembourg overlay on articles 28 to 30 and on the register itself — not 25/893, which is the incident instrument
- Newest change
- Circular CSSF 26/915 of 27 August 2026 extends DORA to third-country branches in Luxembourg where they would qualify as DORA entities in their head office's jurisdiction, and updates six earlier circulars
- Interaction with NIS2
- For financial entities DORA takes precedence as lex specialis; NIS2 still matters for the rest of the group and for your suppliers
Article 28 and the implementing standard
The register of information is a maintenance problem, not a filing problem
The first year, almost everyone built the register as a project: a spreadsheet, a scramble, a submission. That works once. The structural problem appears in year two, when the contracts have changed, the subcontractors have changed, the entity identifiers have changed, and the person who built the spreadsheet has moved on.
The register has to be a by-product of how you manage contracts, not a separate artefact assembled annually. When it is separate, three things follow reliably: it disagrees with the contract database, it disagrees with the risk register, and every submission cycle costs what the first one cost.
Article 28(3) requires the register. What actually goes in each field is set by implementing regulation (EU) 2024/2956, which is the document to work from:
- Every contractual arrangement for ICT services, with the function it supports and the assessment of whether that function is critical or important.
- The provider identified by LEI or EUID, and the ICT service supply chain including the subcontractors that actually deliver.
- The country the service is provided from, and the country where data is at rest and where it is processed.
- Whether an exit plan exists, and how substitutable the provider is — the field that is hardest to answer honestly and most revealing when you do.
- The link back to the contract itself, so the register and the agreement cannot silently drift apart.
The register is also a continuing obligation rather than an annual filing, and it sits alongside article 28 duties that never appear in the submission at all: pre-contractual due diligence, concentration risk, and exit strategies.
If the register only exists in March, it is not a register. It is an annual reconstruction.
The test we apply is simple: could you produce a correct register on any random Tuesday, from the systems you already run, without convening a working group? If not, next year costs what this year cost, and the year after that costs more.
When something happens
The incident clock, and where each stage actually starts
The deadlines chain off each other, which is the part most runbooks get wrong. Under the reporting technical standards a major ICT-related incident requires an initial notification within four hours of classifying it as major, and in any case within 24 hours of becoming aware of it; an intermediate report within 72 hours of that initial notification; and a final report within one month of the intermediate report, or of the latest updated intermediate report. None of the later clocks run from the incident itself.
There is a weekend and bank-holiday derogation allowing submission by noon on the next working day — but it is not available to credit institutions, central counterparties, trading venue operators, or entities designated essential or important under NIS2. For most Luxembourg financial entities, in other words, it is not available.
The four-hour figure is not the hard part. Classification is. Somebody has to decide that this incident is major, and that decision determines whether a clock is running at all. It is a judgement with supervisory consequences, made under pressure, often at night — exactly the kind of decision that must not be automated, and exactly the kind that needs a name, a deputy and a rehearsed route before it is needed.
Significant cyber threats may be notified voluntarily. Many entities never decide in advance whether they will, which means the question gets debated during the event.
Chapter IV
Testing that is allowed to fail
DORA requires a digital operational resilience testing programme, and threat-led penetration testing on top of it for entities the competent authority selects. That selection is worth understanding correctly: it is not a size threshold but a judgement on impact, systemic character, ICT risk profile and ICT maturity. In Luxembourg the framework is TIBER-LU, and the cycle is at least every three years.
The letter of the testing obligation is easy to meet and easy to make meaningless: a test scoped so that it cannot disrupt anything tells you nothing you did not already believe. A test that cannot fail is not a test. The useful version is scoped with the business, scheduled in a window where interruption is permitted, and reported with what broke rather than with a pass mark.
Article 30
If you are on the supplier side of this
Article 30 sets what must be in a contract between a financial entity and an ICT service provider, and it does so in two tiers that are frequently conflated. Article 30(2) applies to every ICT contract: description of the functions and services, the locations of provision and of data processing, data protection and availability, access to and recovery of data on insolvency, service level descriptions, incident assistance, cooperation with competent and resolution authorities, termination rights and notice periods, and participation in security awareness.
Article 30(3) applies only where the ICT service supports a critical or important function, and that is where the demanding clauses live: quantitative and qualitative performance targets, unrestricted rights of access, inspection and audit, participation in threat-led penetration testing, and exit strategies with an adequate transition period. If a redraft lands on your desk with unrestricted audit rights attached to a marginal service, the criticality assessment is the conversation to have first.
Two honest positions matter here, and we hold the second one ourselves. There is no DORA compliance status available to a supplier in general — the regulation creates no certification scheme for providers, most of its obligations rest on the financial entity, and a vendor cannot self-declare its way into conformity. The exception is real and worth knowing: ICT providers designated critical by the European Supervisory Authorities under the oversight framework are supervised directly, with joint examination teams, inspections and penalty payments. That designation applies to a short list of systemically important providers, and a small consultancy is not on it.
So what a supplier like us can honestly offer is this: we accept the clauses of article 30, and we can evidence the things those clauses promise. We are not a CSSF-regulated entity and not a PSF de support, and we say so in the same sentence every time. A supplier claiming DORA compliance on their own behalf is telling you something that is not available to them — which is useful information about the supplier.
Our part
What we do on DORA, and what we do not
We work on making the register maintainable from the systems you already run, on rehearsing continuity and failover for real, on giving the classification and notification chain a named owner and a tested route, and on the testing programme itself. That work sits in ICT risk and resilience, with cybersecurity where the controls themselves are the gap.
This page is a practitioner summary, not legal advice. We do not opine on your legal position, we do not classify your functions for you as a matter of law, we do not represent you before the CSSF, and we certify nothing. Where the question is legal, it belongs with a Luxembourg law firm and we will say so.
