The Digital Operational Resilience Act (DORA) is an EU regulation designed to raise the cybersecurity and operational resilience baseline for the financial sector—especially around information and communications technology (ICT) risks.

For UK-based organizations, DORA can still matter even after Brexit: if you provide services into the EU financial sector, or support EU-regulated firms as an ICT vendor, DORA-driven requirements may flow down to you through contracts, assessments, and oversight expectations.

A quick overview of DORA

DORA is a mandatory EU regulation that provides a risk management framework to strengthen the cybersecurity and resilience of EU financial entities, with a particular focus on ICT-related risks and third-party dependencies.

It is aimed at improving the security and transparency of ICT relationships across the financial ecosystem, including regulated entities such as:

Banks
Investment firms
Insurance companies
Credit institutions
Payment institutions and electronic money institutions

DORA was proposed in 2020, adopted in 2022, entered into force on January 16, 2023, and has applied from January 17, 2025 (after a transition period). As of 2025, supervisory oversight activities are underway to track compliance.

While DORA is an EU regulation and applies directly to EU financial entities, its practical impact can extend beyond EU borders—including to UK entities that provide services into the EU financial sector.

Are UK entities impacted by DORA?

UK entities can be impacted by DORA when they are part of the supply chain for EU-regulated financial entities.

In practice, DORA affects:

UK financial entities operating in the EU or serving EU customers
UK-based ICT third-party service providers (ICT TPSPs) that support EU financial entities

Examples of ICT TPSPs include:

Cloud providers
Cybersecurity vendors
IT consulting and managed service providers

If your UK-based organization provides ICT services to an EU financial entity—or to a UK entity that itself must meet DORA expectations—DORA requirements may show up as contractual obligations (controls, reporting timelines, testing expectations, audit rights, and more).

If your organization operates exclusively in the UK and does not serve EU customers or EU financial entities, DORA compliance is typically not mandatory—but the framework can still be useful as a resilience benchmark.

When DORA applies to UK companies (practical scenarios)

Here are common ways DORA becomes relevant for UK businesses:

1) You sell into the EU financial sector

If you provide services to EU-regulated banks, insurers, investment firms, or payment institutions, you may be asked to demonstrate DORA-aligned controls and evidence to stay eligible as a vendor.

2) You’re an ICT provider supporting an EU entity (directly or indirectly)

Even if you don’t contract with an EU financial entity directly, DORA-driven requirements can flow down through:

Your customer’s vendor risk program
Contract updates and DPAs/MSAs
Assurance requests (questionnaires, audits, penetration test summaries, incident metrics)

3) Your customers demand faster, clearer incident communication

DORA emphasizes incident management and reporting. That often translates into vendor expectations like:

Clear definitions of “major” incidents (and escalation triggers)
Shorter notification timelines
Evidence of detection, containment, and recovery capabilities

4) You’re asked to prove resilience, not just security

DORA pushes organizations to validate operational resilience through testing. As a vendor, you may be asked about:

Business continuity and disaster recovery (BC/DR)
Backup practices and recovery time objectives (RTOs) / recovery point objectives (RPOs)
Control testing and assurance (including for subcontractors)

UK’s DORA-adjacent approach (what to watch)

After Brexit, the UK does not have to mirror EU regulations—but in practice, it often adopts or adapts regimes that align with widely accepted security and resilience expectations.

In 2022, HM Treasury published a policy direction for a regime aimed at managing risks from critical third parties supporting the UK financial sector. While it is not a copy-paste of DORA, the intent overlaps: improving resilience, visibility, and accountability across key ICT dependencies.

For UK financial organizations and ICT providers serving EU customers, the long-term reality may involve preparing for both EU DORA expectations and a UK-adjacent critical third party regime.

Practical reasons to prepare for DORA as a UK entity

Even when DORA does not legally apply to you directly, adopting DORA-aligned practices can be a strategic adSecureSlatege.

Fortified cybersecurity: DORA’s requirements push stronger baselines around risk assessment, detection/response, and resilience.
Better third-party risk management (TPRM): DORA focuses heavily on ICT supply chain risk—useful if you rely on cloud, MSPs, or key subcontractors.
Improved business continuity planning: Many organizations discover BC/DR gaps only during real incidents; DORA encourages preparedness and testing.
Increased buyer trust: Demonstrable resilience and governance can shorten security reviews and help you compete in regulated markets.

Tips to prepare for DORA compliance

If DORA is (or may soon be) relevant to your business, these steps help you prepare without over-scoping.

1) Review and adjust your security posture

Run a structured review against DORA themes (governance, risk management, incident management, testing, and third-party oversight). Focus on what you can evidence—not just what’s documented.

2) Map third-party dependencies

Build an inventory of ICT providers and key subcontractors, then map dependencies between:

Providers → critical systems/processes
Internal apps → external services
Data flows → third-party touchpoints

3) Update security and resilience policies

Identify policies that commonly need tightening for DORA-aligned expectations, such as:

Incident response and communications
Change management
Backup and recovery
Resilience testing practices

4) Adopt (or formalize) a third-party risk framework

If you don’t have a repeatable TPRM program, align to a known structure (e.g., NIST CSF or ISO 27001) and ensure you can:

Classify vendors by criticality
Require and track security/resilience evidence
Manage subcontractor risk (fourth parties)

5) Operationalize incident management

DORA expects an ICT-related incident management process that supports detection, response, recovery, and stakeholder notification. Make sure you have:

Clear severity definitions and escalation paths
Regular tabletop exercises
Evidence that processes operate (tickets, timelines, post-incident reviews)

Become DORA-ready with SecureSlate

SecureSlate helps teams organize and operationalize compliance and operational resilience work—without scattering evidence across spreadsheets and shared drives.

With SecureSlate, you can:

Centralize policies, controls, and evidence for audits and vendor requests
Track third-party risk with structured vendor inventories and recurring reviews
Standardize incident readiness with consistent processes and evidence trails
Maintain audit-ready posture as systems and vendors change over time

If you’re preparing for DORA-related expectations (as an EU-facing UK firm or an ICT provider), SecureSlate can help you build a defensible, repeatable program—so responding to customer due diligence becomes routine instead of disruptive.
