Financial Services: Challenges
The financial sector is a digital frontrunner, with mobile banking, fintech partnerships, and instant payments reshaping customer expectations. At the same time, the sector faces one of the strictest regulatory landscapes. The Digital Operational Resilience Act (DORA), NIS2, PCI-DSS, ISO 27001, and other supervisory requirements demand not only compliance on paper, but demonstrable operational resilience in practice.
Meanwhile, ransomware, fraud, and supply chain attacks are flagged among the top systemic risks by regulators and boards. The challenge for C-level leaders is clear: ensuring compliance and resilience without slowing down innovation or growth.
Financial Sector: key security needs
- Active protection of accounts, transactions, and customer data.
- Advanced detection & rapid response to cut dwell time.
- Continuous monitoring and testing of external and internal attack surfaces.
- Proven incident playbooks and crisis communications.
- Demonstrable compliance with sector specific security frameworks and audits.

“The sector and the partners we work with maintain increasingly high security standards for IoT-products and services. Protecting the privacy of individuals in the images and the sensitivity of the information the drones collect, such as on objects in critical infrastructure, requires our security to be airtight. With Defion, we are working with a professional partner who can support us at the right level. The collaboration also fits perfectly within our strategy to deliver reliable and secure drone technology to European customers.”
Benjamin van der Hilst Co-Founder & CEO
“New requirements from NIS2 for OT systems are increasing the focus on security. With Defion, we know we have the right expertise in-house to keep our systems secure. The collaboration was easy and pleasant; the specialists truly sat next to us rather than across from us. Thanks to their openness and expertise, we are working together toward the same goal: optimal security. This gives us the confidence to face the future.”
Alexander OdijkTeam Manager
“If you look at where we were ten years ago, we’ve made enormous progress. The sense of control is greater. With Security Assurance and MDR we have set up processes and control mechanisms that allow us to limit the impact of a potential attack. The collaboration also serves as a constant reminder to maintain focus on security and set the right priorities in that area. It keeps us alert and sharp. Moreover, Defion’s specialists are highly technical and passionate about their field. That clearly shows in their services.”
