603 The EU Cyber Resilience Act (CRA) marks a significant shift in how cybersecurity is regulated across the European market. For the first time, the regulation introduces legally binding, horizontal cybersecurity requirements for products with digital elements — covering both hardware and software — across their entire lifecycle. While much of the early discussion around the CRA has focused on device manufacturers and consumer IoT, the implications extend well beyond endpoints. For organizations that design, deploy, or operate large-scale data infrastructure, the CRA raises important questions about secure-by-design architectures, long-term vulnerability management, and the role of storage platforms in overall cyber resilience. This article looks at the Cyber Resilience Act through the lens of data infrastructure and storage, clarifying what the regulation requires, how responsibilities are distributed across the supply chain, and why storage architecture plays a foundational role in meeting CRA objectives. Understanding the Cyber Resilience Act The Cyber Resilience Act is an EU regulation that sets mandatory cybersecurity requirements for any product with digital elements that is placed on the EU market. This includes products that connect directly or indirectly to a network or another device, whether they are sold to consumers or enterprises. The regulation applies across the full product lifecycle, from design and development to deployment, maintenance, and end-of-life. Unlike sector-specific legislation, the CRA establishes a baseline that applies broadly, with additional obligations for products classified as higher risk. The stated goals of the CRA are to: Improve the cybersecurity of digital products placed on the EU market Ensure security is built in by design and enabled by default Reduce the number of exploitable vulnerabilities Increase transparency and accountability across the supply chain The regulation entered into force in December 2024. Vulnerability reporting obligations apply from September 2026, with the main product cybersecurity requirements becoming enforceable in December 2027. Scope: what products and actors are covered The CRA applies to “products with digital elements,” a deliberately broad category that includes: Software, including standalone applications and embedded software Network-connected hardware and appliances Components that are integrated into larger systems For enterprise environments, this scope is particularly relevant. Infrastructure software, storage platforms, data management systems, and cloud-adjacent products may all fall within scope when they are placed on the EU market. The regulation also defines responsibilities for different economic operators, including: Manufacturers, who design and develop the product Importers, who place products from outside the EU onto the EU market Distributors, who make products available within the EU Manufacturers carry the most extensive obligations, but importers and distributors are also required to verify compliance and act when risks are identified. Core CRA requirements At a high level, the CRA requires that products meet essential cybersecurity requirements before they can be placed on the EU market. These requirements are deliberately outcome-oriented rather than prescriptive, allowing flexibility in implementation while setting clear expectations. Key requirements include: Security by design and by default Products must be designed, developed, and produced in a way that ensures an appropriate level of cybersecurity based on the risks involved. Secure configurations must be enabled by default, rather than relying on customers to harden systems after deployment. For infrastructure and storage platforms, this reinforces the importance of hardened defaults, minimal attack surfaces, and architecture-level security controls that do not depend on manual configuration. Vulnerability management across the lifecycle Manufacturers are required to implement processes to identify, document, and remediate vulnerabilities throughout the supported lifetime of the product. This includes: Handling vulnerabilities reported internally or by external researchers Providing security updates without undue delay Communicating clearly with users about risks and remediation From September 2026 onward, actively exploited vulnerabilities and severe incidents must be reported to relevant authorities within defined timelines. Protection against unauthorized access and data compromise Products must be designed to prevent unauthorized access, data modification, and data loss. This requirement is particularly relevant for systems that store, process, or manage large volumes of sensitive or regulated data. Encryption, access control, and integrity mechanisms are all part of this expectation, but the CRA places emphasis on effectiveness rather than checkbox compliance. Transparency and conformity assessment Manufacturers must document how their products meet CRA requirements and perform conformity assessments before placing products on the market. Depending on product classification, this may involve self-assessment or third-party evaluation. Compliance is demonstrated through CE marking, aligning cybersecurity with other established EU product safety frameworks. Why data infrastructure matters for CRA compliance Although the CRA is framed at the product level, its objectives cannot be met through isolated controls alone. Data infrastructure plays a central role in whether systems can realistically meet CRA expectations over time. Modern attacks increasingly target data rather than availability alone. Ransomware, data exfiltration, and integrity attacks are designed to compromise trust in data, disrupt recovery, and extend the impact of breaches beyond initial access. From a CRA perspective, this has several implications. Resilience goes beyond perimeter security The CRA assumes that vulnerabilities will occur and that breaches may happen. As a result, resilience — the ability to withstand, contain, and recover from incidents — becomes a core compliance concern. For storage platforms, this means designing systems that protect data even when credentials are compromised, services are misused, or attackers gain partial access to infrastructure components. Secure defaults must extend to data protection Secure-by-default requirements are difficult to satisfy if core data protection mechanisms are optional or bolt-on. Features such as immutability, strong access controls, and encrypted storage must be integral to the platform rather than advanced configuration options. Long-term support and updateability are essential The CRA explicitly links security obligations to the expected lifetime of the product. For infrastructure software that may be deployed for many years, this reinforces the importance of: Clear support policies Predictable security update processes Architectures that can evolve without disrupting operations Storage architecture as a foundation for cyber resilience In the context of the CRA, storage is not simply a passive component. It is a foundational layer that determines whether higher-level security and recovery objectives are achievable. Several architectural principles are particularly relevant. Immutability and integrity protection Immutability plays a key role in protecting against data destruction and corruption. When implemented at the storage layer, immutability prevents data from being altered or deleted, even by privileged accounts, for the duration of defined retention policies. This capability directly supports CRA goals related to data integrity, recovery, and resistance to ransomware-style attacks. Strong access isolation and least privilege Storage systems are a high-value target. Architectures that enforce strict separation of duties, role-based access, and zero-trust principles reduce the impact of compromised credentials and limit lateral movement. From a CRA standpoint, this helps demonstrate that reasonable measures are in place to prevent unauthorized access and data misuse. Distributed and encoded data layouts Distributed storage architectures that use erasure coding or similar techniques add an additional layer of protection. Data is fragmented and spread across multiple nodes, making it significantly harder to reconstruct or manipulate without full system context. This aligns with CRA expectations around preventing unauthorized disclosure and maintaining availability and integrity even under adverse conditions. Multi-site resilience and recovery Geographic replication and multi-site architectures support both availability and recovery objectives. In the event of a security incident or infrastructure failure, organizations can restore access to trusted data copies without relying on compromised environments. This capability supports business continuity while reinforcing compliance with CRA requirements around incident handling and recovery. CRA and the shared responsibility model One of the practical challenges of the Cyber Resilience Act is its interaction with complex supply chains. Few products exist in isolation; most enterprise systems are composed of multiple software components, platforms, and services. The CRA does not eliminate shared responsibility, but it does clarify accountability. Manufacturers remain responsible for the security of the product they place on the market, including how it integrates third-party components. For organizations building on storage and infrastructure platforms, this places renewed emphasis on: Choosing components with clear security roadmaps and long-term support Understanding how underlying platforms handle vulnerabilities and updates Documenting architectural decisions that support compliance Storage platforms that embed security and resilience into their core design simplify this process by reducing reliance on external compensating controls. From compliance to operational resilience While the CRA is a regulatory instrument, its underlying objectives are operational. The regulation reflects a broader recognition that cybersecurity failures have systemic consequences and that baseline resilience must be built into digital products from the outset. For data-intensive organizations, this aligns regulatory compliance with long-standing operational priorities: Protecting data integrity and availability Ensuring reliable recovery after incidents Reducing the impact of inevitable vulnerabilities Rather than treating the CRA as a documentation exercise, organizations can use it as a framework to reassess how well their infrastructure supports these goals in practice. Conclusion The Cyber Resilience Act establishes a new baseline for cybersecurity in the EU, with implications that extend deep into data infrastructure and storage design. By emphasizing security by design, lifecycle vulnerability management, and resilience under attack, the CRA shifts attention from reactive controls to foundational architecture. For organizations operating large-scale data platforms, storage is a critical enabler of CRA objectives. Architectures that embed immutability, access isolation, distributed protection, and recovery capabilities provide a stronger foundation for both regulatory compliance and long-term operational resilience. As CRA enforcement approaches, aligning infrastructure choices with these principles will be essential — not only to meet regulatory requirements, but to maintain trust in data in an increasingly hostile threat environment.
