Operator obligations bank consulting: legal compliance and security in the financial sector

Operator obligations in the banking sector cover the legally compliant operation of critical technical systems such as fire alarm systems, intrusion detection systems and standby power systems. This requires detailed planning, regular checks and complete documentation in accordance with national and European regulations such as KWG, MaRisk and DORA. Independent consulting helps banks meet these complex requirements and avoid liability risks.

Comprehensive planning and independent expertise for critical infrastructure in banks

Independent consulting is crucial to ensure legal compliance, minimise risks and increase efficiency at the same time.

Key Takeaways

• Operator obligations in the banking sector are complex and encompass legal, technical and organisational requirements, in particular through KWG, MaRisk and DORA.
• Manufacturer-independent, independent planning of fire alarm systems and other critical infrastructure is crucial to ensure legal compliance and avoid manufacturer dependency.
• Comprehensive risk management, continuous review and complete documentation are not only mandatory, but also offer significant economic advantages through cost optimisation and increased operational safety.

The financial sector is a cornerstone of modern economies and is subject to particularly strict regulation. Banks are responsible not only for the security of the assets and data entrusted to them, but also for the legally compliant operation of their entire infrastructure. Operator obligations for technical systems in banks are complex, multi-layered and require a high degree of expertise. Failure to comply with these obligations can have far-reaching legal, financial and reputational consequences. In this environment, well-founded, independent consulting is essential to keep an overview and implement the necessary measures precisely.

The complexity of operator obligations in the banking sector

Banks operate in a highly regulated environment shaped by national and European regulations. Operator obligations extend across a wide range of areas, from physical security to digital resilience. Central legal foundations in Germany include the Banking Act (Kreditwesengesetz, KWG), the Minimum Requirements for Risk Management (MaRisk) of the Federal Financial Supervisory Authority (BaFin), and, since 17 January 2025, also the EU's Digital Operational Resilience Act (DORA). These sets of rules place comprehensive requirements on risk management, organisational guidelines and emergency processes. The board or management of a bank bears overall responsibility for compliance with these obligations; delegation does not release them from their duty of oversight.

The challenge lies in translating these abstract legal requirements into concrete technical and organisational measures. This concerns not only IT security in the narrower sense, but also the physical security of buildings and the availability of critical infrastructure. Financial institutions are often classified as critical infrastructure (KRITIS), which brings additional obligations under the IT Security Act and the NIS2 Directive. Continuous monitoring and adaptation to new threats and technologies is of crucial importance here. Complete documentation of all measures is not only a requirement, but also an essential tool for demonstrating compliance in the event of a claim. This complexity requires specialist knowledge and a strategic approach, in order to act both legally compliantly and efficiently.

Technical systems and their legally compliant operation in banks

The legally compliant operation of technical systems is of existential importance for banks. This covers a wide range of systems essential for smooth business operations and the protection of assets and data. These include, in particular, fire alarm systems (BMA), intrusion detection systems (EMA), video surveillance systems, access control systems, evacuation systems, and standby power systems and uninterruptible power supplies (UPS). Each of these systems is subject to specific standards and guidelines, compliance with which is not only a legal requirement, but is also demanded by insurers and supervisory authorities such as BaFin. Digitalisation and the use of complex software solutions also create new vulnerabilities that must be continuously monitored and secured.

The requirements go beyond mere installation. They encompass needs analysis, professional planning, installation by certified specialist firms, regular maintenance and testing, and complete documentation over the entire life cycle of the system. For example, fire alarm systems must be planned, installed and maintained in accordance with DIN 14675 and VdS 2095, to function reliably in an emergency and alert the fire brigade. Inadequate operation can not only lead to functional failures, but also to criminal and civil consequences for those responsible. Ensuring the availability, integrity, authenticity and confidentiality of information technology systems and processes is decisive for the functionality of the critical infrastructure being operated.

The role of fire alarm systems (BMA) in banks

Fire alarm systems (BMA) play an outstanding role in the security concept of banks. They serve to protect human life, sensitive data and high-value assets. The planning, installation and operation of BMA in banks must follow strict standards and guidelines, to ensure their reliability and legal compliance. The authoritative sets of rules here are DIN 14675 (fire alarm systems - structure and operation), DIN VDE 0833 (alarm systems for fire, intrusion and hold-up) and VdS 2095 (guidelines for automatic fire alarm systems).

DIN 14675-1 describes the structure and operation of fire alarm systems and sets out, among other things, requirements for the fire alarm and alerting concept. DIN 14675-2 defines the requirements for the specialist firms that plan, design, install, commission, accept and maintain these systems. Certification under DIN 14675 is mandatory for specialist firms carrying out fire alarm systems with a connection to the fire brigade. VdS 2095 specifies these requirements further and is often explicitly required by property insurers or clients, since it ensures an even higher level of functional reliability and dependability. Planning a BMA requires a detailed threat and risk analysis and coordination with the supervisory authorities and the operator. Responsibilities in the individual phases must be documented in writing, and a comprehensive concept must be drawn up before the planning phase begins. This ensures the BMA is optimally tailored to the specific risks and conditions of the bank and enables fast, effective alerting and response in an emergency.

Challenges in implementation and avoiding manufacturer dependency

Implementing operator obligations in the banking sector involves considerable challenges. One of the greatest is avoiding manufacturer dependency. Many banks find themselves tied to specific manufacturers, which can severely restrict flexibility in system integration, maintenance and future extensions. This often leads to higher costs, since the negotiating position vis-à-vis the manufacturer is weakened and alternatives are lacking. In addition, proprietary solutions can make interoperability with other systems more difficult and slow down adaptation to new technological developments. The selection of components and systems should therefore always be made with openness and standards compliance in mind.

Other common mistakes in implementation include inadequate as-is analysis and requirements assessment at the start of a project. Without a clear understanding of the existing infrastructure and the actual security needs, planning errors can arise that later require costly corrections. Poor or incomplete documentation is also a recurring problem. Gaps in documentation not only make maintenance and testing more difficult, but can also considerably hinder the demonstration of legally compliant operation in the event of a claim. Finally, the importance of continuous monitoring and adaptation is often underestimated. The threat landscape and regulatory requirements are constantly evolving, so once-implemented solutions must be regularly reviewed and updated. Independent planning that takes all these aspects into account is therefore of inestimable value.

Risk management and continuous review as the core of operator obligations

Effective risk management forms the core of operator obligations in banks. It is about systematically identifying and assessing potential risks and implementing suitable measures to mitigate them. This covers not only financial risks, but also operational risks arising from the failure or impairment of technical systems. MaRisk requires institutions to implement a robust risk management system that covers all material risk types and enables continuous monitoring of risk positions. Management is responsible for defining and adapting risk strategies and must ensure their implementation.

Continuous review of technical systems and associated processes is essential. This includes regular audits, threat and risk analyses and stress tests, to test the resilience of systems against cyberattacks and other disruptions. In particular, the Digital Operational Resilience Act (DORA), applicable since 17 January 2025, obliges financial companies to implement comprehensive ICT risk management, including the detection, handling and reporting of ICT-related incidents. BaFin expects audits to be carried out on the basis of a risk-oriented approach. Proactive adaptation to new technologies and changing regulations is necessary, to ensure the bank's digital and physical resilience. This requires not only technical expertise, but also a deep understanding of the regulatory landscape and the bank's specific business models.

The process of legally compliant planning and implementation with PLANATEL®

The legally compliant planning and implementation of technical systems in banks is a structured process that PLANATEL® accompanies comprehensively. Our approach is designed to ensure maximum transparency, efficiency and legal compliance. The process begins with a detailed as-is survey and needs analysis, in which the existing infrastructure is assessed, weak points identified and the bank's specific requirements determined. This includes a comprehensive analysis of regulatory requirements and internal company guidelines. Based on these findings, we develop a target concept that defines the optimal technical and organisational solutions, always taking manufacturer independence and long-term cost-efficiency into account.

We then prepare detailed tender documents containing precise service descriptions, technical specifications and contractual conditions. This enables fair competition among potential installers and secures the selection of the most suitable provider. We accompany the entire award and implementation process, monitor compliance with plan specifications, and support coordination between the parties involved. Final acceptance of the systems takes place according to strict criteria, to verify the contractually agreed performance and full functionality. We also offer support in developing maintenance concepts and selecting certified maintenance providers. This holistic approach ensures that banks receive not only technically high-quality, but also permanently legally compliant and efficient solutions.

Economic benefits through optimised operator obligations

Careful fulfilment of operator obligations in banks is not only necessary to minimise risk and ensure legal compliance, but also offers significant economic advantages. Optimised planning and operation of technical systems leads to substantial cost optimisation. Manufacturer-independent tenders and a precise needs analysis avoid unnecessary investment and achieve the best terms on the market. This applies both to acquisition costs and ongoing operating and maintenance costs. In the long term, efficient infrastructure leads to less downtime and reduced maintenance effort, sustainably lowering operating costs.

Forward-looking planning also contributes to preserving the value of properties and systems. Systems that are regularly maintained and kept up to date have a longer service life and function more reliably. This protects the bank's investments and avoids costly emergency repairs or premature replacement purchases. A further advantage is the increase in operational efficiency. Well-planned, integrated systems enable smooth processes and support employees in their daily work. Reducing security incidents and system failures minimises operational disruption and protects against financial losses from data leaks or fraud. Ultimately, demonstrable legal compliance and high security standards strengthen the trust of customers, supervisory authorities and investors, which has a positive effect on the bank's image and competitiveness.
