Digital resilience for financial institutions
From DORA to demonstrable technical assurance
Financial institutions depend on trust, availability and the integrity of transactions. Banks, insurers, asset managers, payment service providers and fintechs process sensitive financial data and rely on digital processes that must remain continuously available. A vulnerability in identity, core systems, payment chains, cloud, SaaS, APIs or network segmentation can directly affect customer trust, transactions and operational continuity.
Since 17 January 2025, DORA has applied to financial institutions within the scope of the regulation. DORA makes digital operational resilience concrete: ICT risks must be demonstrably managed, major ICT incidents must be reportable, ICT service providers must be understood and digital resilience must be tested periodically. This shifts cybersecurity from policy and implementation towards demonstrable effectiveness.
DeepBlue helps financial institutions determine which risks are actually exploitable. Not only from a compliance perspective, but from an attacker’s perspective. We examine how an attacker gains access, which privileges can be expanded, which systems can be reached and what impact is possible on financial processes. Tooling and AI support analysis and efficiency. The core remains technical expertise, context and demonstrable impact.

DORA requires not only appropriate security measures, but also evidence that those measures work in practice. That assessment must be periodic and demonstrable, and it extends to ICT services that have been outsourced. A penetration test, TLPT or security assessment validates that effectiveness technically.

Ransomware directly affects digital operational resilience. Attackers gain administrative privileges, sabotage backups, evade detection and disrupt critical systems. Outages in payment flows, reporting, customer channels or core systems may be relevant under DORA for continuity, incident reporting and recovery capability.

Identity is a primary attack surface in financial environments. Attackers abuse weak MFA, shared accounts, excessive privileges, service accounts and insufficiently controlled external access. DORA makes this control important because identity often forms the gateway to critical functions and outsourced ICT services.

Customer portals, mobile apps and online banking process sensitive data and often connect to underlying core systems. Vulnerabilities such as broken access control, IDOR, weak session security and insufficient input validation can affect customer data, transactions and the reliability of digital services.

Payment infrastructure, transaction processing, external integrations and open banking through APIs are attractive targets. Attackers look for weak authentication, manipulable transaction logic and insufficient validation between systems. These chains require technical validation because weaknesses can directly affect integrity and availability.

Cloud and SaaS are used for collaboration, analytics, data processing and supply-chain exchange. Risks arise from misconfigured tenants, public storage, excessive privileges, weak logging and insecure integrations. Under DORA, ICT third-party risk is also important, so cloud configuration and supplier arrangements need to be assessed together.

Financial institutions depend heavily on software suppliers, technology partners, managed service providers and outsourced ICT services. Attackers abuse these trust relationships through remote administration, VPN access, shared accounts or management portals. DORA makes this an explicit part of digital resilience.
In financial environments, the greatest risk often lies in the connection between systems. A vulnerable customer portal can provide access to an internal API. An unnecessarily reachable management system can enable lateral movement. A service account with excessive privileges can provide access to financial data or administrative functions. DeepBlue therefore looks not only at individual vulnerabilities, but at the path an attacker can follow: from initial access to privilege escalation, data access, process disruption and impact on critical financial systems.
These attack paths are directly relevant to DORA. A vulnerability is not only a technical issue, but can affect the availability of critical functions, the integrity of transactions, incident detection, outsourcing risk and recovery capability. By technically validating attack paths, financial institutions gain evidence that is useful for security teams, risk management, compliance and executives.
DeepBlue translates findings into technical detail, remediation priorities and practical measures. Examples include stronger segmentation between core systems and office automation, tighter privileges on identity and service accounts, hardening of external access, restriction of management interfaces and improved logging and detection. This creates one clear view of digital resilience, not only for audit and compliance, but primarily for the functioning of the organisation itself.

Awareness and skills determine how well staff recognise and respond to threats. DeepBlue delivers phishing simulations, awareness training and technical exercises for SOC and IT teams. The content aligns with your processes, roles and realistic attack scenarios.

Red teaming is relevant for organisations that want to test their detection, response and resilience against realistic attack paths. The focus is on goal-driven scenarios, such as access to sensitive data, lateral movement towards business-critical systems or evasion of detection.

A Managed SOC supports organisations with continuous detection, triage and follow-up. Its value lies in use cases that reflect real attack paths, such as identity abuse, suspicious access to sensitive data, lateral movement and anomalous behaviour in cloud environments.

Speed is critical during incidents. DeepBlue investigates how an attacker gained access, which systems were affected, which data may have been accessed and which measures are needed to restore operations safely.

CISO as a Service supports organisations with security strategy, risk steering, supplier control, incident preparation and technical prioritisation. The focus is on actionable measures that fit your processes and available capacity.

Physical access can have digital impact. Consider workstations, reception desks, network ports, offices, server rooms and supplier zones. Physical security testing shows where physical security, human behaviour and cyber risk meet.
