The role of the Chief Information Security Officer (CISO) has changed. Anyone responsible for information security today no longer works only on firewalls and access rights, but at the intersection of technology, law, and business strategy. Data protection and compliance have become central mandatory tasks, and regulatory pressure is increasing. Since the NIS2 Implementation Act came into force at the end of 2025, management boards have, for the first time, been personally liable for cyber risks, and the GDPR remains an integral part of daily operations. For CISOs, the question is therefore less whether they need to consider data protection and informationsecurity together, but rather how to implement this efficiently and in an audit-proof manner.
This article shows the specific challenges CISOs face regarding data protection, why spreadsheets and scattered documents reach their limits, and how Athereon GRC, as a leading European GRC platform, helps build an audit-ready information security management system.
Why Data Protection and Compliance Are Core CISO Tasks Today
For a long time, data protection was considered the domain of the legal department or the data protection officer, while the CISO handled technical security. In practice, this separation can hardly be maintained any longer. Data protection and information security share the same subject matter: information worth protecting. Anyone maintaining a record of processing activities under Article 30 of the GDPR is essentially describing the same data flows, systems, and responsibilities that are also relevant in information security management. If both areas are documented separately, duplicate work, inconsistencies, and blind spots arise.
On top of this comes regulatory consolidation. The German NIS2 Implementation Act, which came into force on December 6, 2025, expands the scope of affected companies from around 4,500 to approximately 29,500 entities across 18 sectors. Companies typically affected are those with 50 or more employees or annual revenues of €10 million in the relevant industries. The law requires risk management measures, short reporting deadlines for security incidents, and seamless documentation. There is also no transition period. Affected organizations must be able to fulfill their obligations from day one.
For CISOs, this means: Data protection, information security, and business continuity are no longer isolated silos, but parts of an interconnected compliance framework that must be demonstrable at any time.
Common pitfalls in day-to-day data protection
In practice, audit-ready data protection rarely fails due to a lack of goodwill, but rather due to how the work is organized. The following obstacles appear particularly often:
- Fragmented documentation. Records of processing activities live in a spreadsheet, technical and organizational measures (TOMs) in a text document, and risk assessments in a third source. As soon as a process changes, several documents have to be updated by hand—an error-prone effort that often gets neglected in day-to-day operations.
- Missing link between data protection and ISMS. An asset classified as critical in the ISMS may not appear at all in data protection records, or may appear under a different name. Without end-to-end integration, it is impossible to reliably answer which personal data resides on which system and which measures protect it.
- Lack of verifiability. In an audit or in response to an inquiry from a supervisory authority, what counts is not what was done, but what can be proven. Anyone who only starts gathering evidence shortly before the audit comes under pressure and risks gaps.
- Reactive rather than continuous maintenance. Compliance is often handled as a project once a year before certification. Between audits, the documentation becomes outdated and the actual state diverges from what is documented.
- Data protection incidents under time pressure. The GDPR requires that reportable breaches be notified within 72hours (Article 33), while NIS2 even mandates an initial report of significant security incidents within 24 hours. Without prepared processes and clear responsibilities, this is nearly impossible to meet.
What defines audit-ready information security management
At its core, audit readiness means being able to demonstrate at any time that the right measures have been defined, implemented, and reviewed. Three characteristics are essential for this.
First, a centralized, consistent data foundation is required. All relevant information—assets, processes, risks,measures, and responsibilities—resides in one place and is interconnected. If one element changes, the dependencies become immediately visible.
Second, audit-proof reliability is required. Every change must be logged in a traceable manner. An audit trail documents who changed what and when. This builds trust with auditors and makes your compliance posture robust.
Third, a good management system thrives on continuous monitoring rather than one-off heroic efforts. Automated reminders, recurring tasks, and ongoing monitoring ensure that the documentation reflects the actual state—not the state at the time of the last audit.
How Athereon GRC supports CISOs with data protection and compliance
Athereon GRC is a modular, cloud-based GRC platform developed and operated in Germany. It unifies the ISMS, ERM, BCM, DSM,and SRM modules on a single data foundation—precisely where CISOs would otherwise have to switch between separate tools.
Data protection and ISMS on a single platform
Instead of running data protection and information security in parallel in different systems, Athereon GRC links both disciplines through a shared model of assets, processes, and measures. A record of processing activities under Article 30 GDPR can be built using guided workflows, including the management of retention periods, legal bases, and safe guards. Because the same assets are also referenced in the ISMS, duplicate maintenance is eliminated and inconsistencies are avoided.
Data protection impact assessments and incident management
Risk-based data protection impact assessments can be carried out on the basis of customizable risk criteria and stored in an audit-proof manner. For managing data protection incidents, the platform guides you through the requirements of Articles 33 and 34 of the GDPR: from assessing the data categories affected and managing the response measuresto notifying data subjects and supervisory authorities. This makes it possible to meet even the tight reporting deadlines under real-world time pressure.
Framework-agnostic for ISO 27001, BSI IT-Grundschutz, TISAX® and NIS2
Athereon GRC is framework-agnostic and supports a wide range of standards, including ISO 27001, ISO 27701, BSI IT-Grundschutz, TISAX®, DORA, and NIS2. Since many requirements overlap—an existing ISMS based on ISO 27001 typically already covers a large portion of NIS2 obligations—work that has been done once can be leveraged across multiple standards. Controls from different catalogs can be linked to one another, so that a single measure satisfies several regulatory requirements at the same time.
AI agent LAiKA: support with full user control
Part of the recurring work is handled by the AI agent LAiKA. It is designed so that control always remains with you. True to the guiding principle: Nothing without your OK. LAiKA suggests, prepares, and structures, but it never makes decisions over your head.
The support follows a clear escalation logic: from the foundation through LAiKA Assist to the specialist agents. At the entry level, LAiKA Assist answers questions and helps with everyday tasks. When things get more specific, the specialist agents take over:
- The Infrastructure Mapper helps you capture systems and assets and map them within the platform.
- The Compliance Assistant helps with handling compliance tasks in line with the relevant standards.
- The Questionnaire Assistant helps with answering questionnaires, for example as part of assessments or supplier inquiries.
Especially for CISOs, who depend on traceability, this principle is essential: LAiKA takes work off your hands without relinquishing authority over decisions and documentation.
Audit management and audit-proof records
For preparing and conducting audits, the platform offers comprehensive reporting features, automated reminders, and structured tracking of open items. An audit trail seamlessly logs all changes. The result is a compliance status that no longer needs to be laboriously pieced together but is ready for review at anytime.
100% Made in Germany and GDPR-compliant operations
When it comes to data protection in particular, where and how your own compliance data is processed matters. Athereon GRC stores data exclusively in Germany, encrypts information both in transit and at rest, and is itself ISO 27001-certified. For CISOs who value digital sovereignty and protection from third-country access, this is a factor that carries significant weight: "Made in Germany" here refers to actual operations, not merely a label.
Compliance as an opportunity: from obligation to advantage
Data protection and compliance are often perceived as a necessary evil—something that ties up resources without creating any discernible added value. This view falls short. A well-managed, audit-ready information security management system not only reduces liability and fine risks, it also builds trust with customers, partners, and regulators. An ISO 27001 certification or a successfully completed TISAX® assessment is increasingly a prerequisite for even being considered as a business partner.
This is where the essence of compliance as an opportunity lies: When data protection and information security come together on a single platform, the maintenance effort drops and the time saved flows into actual security work rather than managing documents. Athereon GRC automates recurring tasks, connects disciplines that would otherwise be handled separately, and makes your compliance status visible at all times.
Conclusion
For CISOs, data protection is no longer a peripheral task but an integral part of effective information security management. The regulatory pressure from GDPR and NIS2 makes it essential to consider both areas together and keep them demonstrable at all times. Fragmented spreadsheets and scattered documents can no longer meet this requirement.
Athereon GRC provides the foundation for implementing data protection and compliance efficiently, in line with standards, and in an audit-ready manner: on a single, audit-proof data foundation, operated in Germany, supported by AI agent LAiKA, and with full control on your side. This transforms a mandatory exercise into a resilient system that relieves CISOs during audits and gives the company a real advantage.
