How CyberSilo Helped a European Bank Achieve DORA Compliance

The DORA Compliance Landscape for European Banks

DORA, effective from January 2025, represents a paradigm shift in how financial entities across the European Union manage their operational resilience. It moves beyond traditional business continuity and disaster recovery (BCDR) to create a comprehensive framework that integrates ICT risk management, incident reporting, digital operational resilience testing, third-party risk, and information sharing. For the bank in this case study, a mid-tier institution with operations in three EU member states, the primary challenges were fragmentation and a lack of centralised oversight.

The bank’s existing compliance efforts were siloed: its IT department managed technical controls, the risk team handled BCDR, and the procurement department oversaw third-party contracts with little coordination. This structure was inadequate for DORA’s requirements, which demand an integrated view of risk across all ICT systems and a single, auditable reporting chain. Without a unified platform, the bank risked failing to meet DORA requirements related to ICT risk management (Article 6), where the institution must identify, classify, and document all ICT assets and processes supporting critical business functions.

The Challenge: Fragmented ICT Risk Management

The bank’s initial compliance gap analysis, conducted with CyberSilo, identified several critical deficiencies directly tied to DORA’s core pillars. The most pressing issue was the lack of a centralised ICT risk management framework. The bank had multiple tools for asset management, vulnerability scanning, and event logging, but no single source of truth. This made it impossible to produce the comprehensive risk assessments DORA mandates.

A second major challenge was third-party risk management, or DORA’s “ICT third-party risk” pillar. The bank relied on over 40 third-party ICT service providers, including core banking system vendors, cloud infrastructure providers, and payment processing firms. DORA requires financial entities to maintain a register of information and communication technology (ICT) third-party providers (Article 28) and to assess their concentration risk. The bank’s existing contracts and risk assessments were stored across different departmental folders, with no standardised process for reviewing or reporting on this critical data.

The Approach: A Phased Implementation with CyberSilo

CyberSilo worked with the bank’s CISO, head of compliance, and DPO to design a phased programme built around the CyberSilo Compliance Platform. The plan was structured to deliver early wins while building toward full DORA compliance within twelve months. The phased approach aligned directly with DORA’s five pillars, allowing the bank to demonstrate progress to its board and regulators.

The first phase focused on establishing a centralised asset and risk register. The second phase automated incident detection and reporting. The third phase addressed third-party risk management and resilience testing.

Key Technical Integrations

The success of the project depended on seamless integrations between the CyberSilo Compliance Platform and the bank’s existing security and IT management tools. The platform integrated directly with the bank’s SIEM to ingest threat data for incident detection, and with its GRC platform to map DORA controls to existing policy documents. A critical integration was with the bank’s core banking system APIs, which allowed the platform to monitor system performance and availability data in real time, directly supporting the DORA requirement for continuous monitoring of critical ICT systems (Article 9).

Results: Auditable DORA Compliance in Under 12 Months

Within twelve months, the bank achieved a state of demonstrable, auditable compliance across all five pillars of DORA. The CyberSilo Compliance Platform provided a single dashboard for the CISO and board to view real-time risk posture, incident status, and third-party risk scores. The bank passed its first pre-compliance audit by its national competent authority with zero critical findings.

The measurable business outcomes were significant. The bank reduced the time spent on manual compliance reporting by 70%, freeing its GRC team to focus on strategic risk analysis. The automated incident reporting process ensured that all reportable ICT incidents were filed with the regulator within the mandatory two-hour window for major incidents, eliminating the risk of fines for late reporting.

The transformation also strengthened the bank’s third-party risk posture. The centralised register revealed previously unknown concentration risks with two cloud providers, allowing the bank to adjust its sourcing strategy and negotiate stronger contractual protections before the DORA enforcement date.

Key Takeaways for European Financial Institutions

This case study offers several actionable lessons for banks, insurers, and other financial entities subject to DORA. First, a centralised, automated compliance platform is not a luxury but a necessity for managing the scale and complexity of DORA’s requirements. Manual processes cannot deliver the continuous monitoring and reporting the regulation demands.

Second, governance and integration matter more than point solutions. The bank succeeded because it first established a unified data model for its assets, risks, and third parties, and then integrated its existing tools into that model. The technology served the governance framework, not the other way around.

Finally, start early with third-party risk management. DORA’s requirements for ICT third-party risk are extensive and require an ongoing process, not a one-off assessment. The EU cybersecurity compliance services provided by CyberSilo offer a structured approach for institutions beginning this journey.

For any financial institution subject to DORA, the path to compliance begins with a clear understanding of the gaps between current-state capabilities and the regulation’s demands. The bank’s success demonstrates that with the right framework and platform, full compliance is achievable within a realistic timeframe.

Frequently Asked Questions About DORA Compliance

What is the most challenging part of DORA for banks?

For most banks, the ICT third-party risk management pillar (Articles 28–30) presents the greatest challenge. It requires the creation of a comprehensive register of all ICT third-party providers, ongoing monitoring of their performance and security, and assessment of concentration risk. This is an operational shift from traditional annual vendor risk assessments to a continuous oversight model.

How does DORA intersect with NIS2 for financial services?

Financial institutions already regulated by DORA are exempt from NIS2’s scope, as DORA is considered sector-specific legislation with equivalent or stricter requirements. However, the technical and operational resilience measures required under both frameworks are largely aligned. Institutions that maintain robust DORA compliance will generally meet NIS2 requirements for ICT security, incident reporting, and supply chain security as well.

What are the penalties for non-compliance with DORA?

Penalties for non-compliance are significant and are enforced by national competent authorities. For legal entities, administrative fines can reach up to 2% of the total annual worldwide turnover or €10 million, whichever is higher. Individuals responsible for compliance failures can face fines up to €1 million. Beyond financial penalties, regulators can impose operational restrictions, including limiting the bank’s ability to offer certain services.
