Key takeaway: Many technical controls in ISO 27001:2022 can be directly implemented with QNAP products
For enterprise clients, government tenders, and even cybersecurity insurance underwriting, ISO 27001 has become a necessary requirement for cooperation. The latest version, ISO 27001:2022 Annex A, lists the control items that organizations should evaluate and adopt, including technical controls directly related to datastorage, such as access management, backup and restore, anti-tampering, system redundancy, encryption, and audit logs. Many QNAP products are natively equipped with or can directly enable these features, helping enterprises provide the technical control evidence required for ISO 27001 audits.
The target of ISO 27001 certification is the organization's Information Security Management System (ISMS). Although no single product can be “certified” or “achieve” certification, choosing the right storageunit allows you to provide corresponding mechanisms and records for each technical control item during audits.

Comprehensive access control
ISO 27001 requires that access to information and systems be restricted according to business and security needs, with permissions granted only to authorized users (A.5.15, A.5.18, A.8.3). QNAP NAS supports establishing role-based access control (RBAC) groups and integrates with AD, Azure AD, or LDAP, allowing permission changes to be managed directly within the original domain account system, without the need to maintain a separate user list on NAS.
For privileged accounts such as administrators (A.8.2), QNAP provides Authenticator multi-factor authentication (MFA) and SSO integration, making access to high-privilege accounts even more secure.

Data backup and restore
ISO 27001 requires that backups must be planned, implemented, and regularly tested to ensure that data can be restored after loss or damage (A.8.13). Through HDP for PC/VM, Windows PC/Server and VMware, Hyper-V virtual machine data backups can be made to QNAP NAS, and HDP Recovery Media Creator can be used to import backups into Virtualization Station for boot verification, ensuring that the backup can truly restore. HDP for Business* further automates this verification process, and with Video Verification, the boot process of the restored VM is recorded, providing the most direct evidence for backup verification during audits.

Storage layer integrity: ZFS static data damage is automatically detected and automatically repaired
In addition to data backup, QNAP provides data security protection that exceeds the requirements of clause A.8.13. The ZFS file system of QuTS hero calculates a checksum for each block when writing data, and stores the checksum in the upper layer, within the index structure pointing to this block, rather than together with data. This way, the checksum will not be damaged together with data, forming a hierarchical verifiable check chain. During reading, the system automatically compares, and if a mismatch is found, it uses the same-level or mirrored copy to repair the damaged block. This proactive self-healing capability not only achieves automated maintenance without manual intervention, but also provides enterprises with data protection that surpasses basic backup requirements.
WORM (Write Once Read Many) tamper-proof: data immutability
Backup ensures that after data loss, there is a copy available for restore, and ZFS verifies and ensures that the copy itself will not be silently corrupted. However, neither of these can prevent "intentional deletion or tampering by malicious actors." ISO 27001 requires that records be protected to prevent unauthorized tampering, deletion, or loss (A.5.33), and the recoverability of backups is also extended to tamper-proofing (A.8.13).
QuTS hero NAS operating systems provide regulatory-level immutability protection: set the WORM retention period for data folder that needs protection, and within the period, no one (including administrators) can modify or delete it. Compared to application-layer simulated locking, QuTS hero's WORM is enforced at the file system layer and is not affected by storage protocols.
On the object storage side, QuObjects' S3 Object Lock is also policy-based (specifying Bucket and retention rules), and has obtained Veeam Ready - Object with Immutability Certification, suitable for QTS and QuTS hero operating systems.

System redundancy and high availability: automatic failover in case of failure, reducing service interruptions
ISO 27001 requires that information processing facilities have sufficient redundancy to meet availability requirements (A.8.14). This does not simply mean keeping several extra copies of data, but that the system itself must be able to continue providing services in the event of component failure. QNAP offers the following high availability solutions.
- Dual Controller Architecture: ES1686dc R2 and other model adopt a dual active (Active-Active) controller design, equipped with the same ZFS-based QES operating system. Both controllers operate simultaneously, and if one fails, the other automatically takes over. NVRAM modules are included to reduce the risk of data loss during power outages.
- Dual Machine Failover: QuTS hero model can be configured with High Availability Manager, allowing two independent NAS to form an Active-Passive cluster for mutual backup. When the primary machine encounters an issue, the backup machine automatically takes over services.
- Scale-out Cluster Architecture: QNAP Horizontal Expansionstorage Solution adopts the QuTS MEGA operating system, allowing you to form a cluster with as few as 3 nodes and expand up to 96 nodes; through erasure coding, multiple nodes can fail simultaneously without data lossdata, and in the event of node failure, the system automatically detects, rebuildsdata, and migrates services, making it suitable for PB-leveldata high-availability and flexible expansion requirements.
Encryption Protection: Software encryption and hardware SED, comprehensive security
ISO 27001 requires the establishment and implementation of encryption rules based on risk, to protect the confidentiality and integrity of information (A.8.24).
QNAP provides AES-256 encryption for shared data folder / LUNs; it also supports self-encrypting hard disk drives (SED), covering TCG-OPAL, TCG-Enterprise, as well as TCG-Ruby designed specifically for new-generation storage technologies such as NVMe, allowing data encryption and decryption to be handled directly by the hard disk drives controller, so that neither the operating system nor unauthorized users can access the encryption key, and it does not consume additional host computing resources. The transmission stage can be protected by SMB signature encryption and end-to-end transmission encryption to safeguard data. This ensures that sensitive data is protected during both transmission and at-rest storage stages.
Audit logs: One-time query for complete traceability
ISO 27001 requires the establishment of logs for user activities, exceptional events, and information security incidents, with regular reviews (A.8.15). QTS/QuTS hero supports logging of user access and system events. For a single NAS, no additional configuration is needed; when managing multiple NAS, you can enable QuLog Service to centrally collect and consolidate logs, supporting tagging and advanced search without the need to aggregate across systems.
Conclusion: Choose QNAP to Bridge the Gap Between Control Checklists and On-Site Audits
When implementing ISO 27001, model selection, backup architecture, and HA/Scale-out scale must still be adjusted according to the actual audit scope, data volume, and budget of the enterprise; there is no one-size-fits-all configuration for organizations of all sizes. With QNAP's flexible system architecture and comprehensive product line, we can help enterprises of all sizes transform ISO 27001 requirements into practical technical defenses, building a data protection architecture that is both secure and scalable.
If you have planning, model selection, or customization requirements for implementation, please feel free to contact QNAP sales or technical consultants to plan the most suitable product combination based on your actual audit scope.
