The compliance dilemma: Is software enough, or do you need real experts?
It is the new reality for the upper mid-market: your company no longer just needs to implement the General Data Protection Regulation (GDPR) flawlessly; in B2B business, you must also demonstrate ISO 27001 certification while simultaneously fulfilling the new, strict legal obligations of the NIS2 directive.
The problem in many businesses: these frameworks are treated as completely separate projects. The IT department works on ISO controls, the external data protection officer builds their own system, and management puzzles over NIS2 reporting obligations. The result? Enormous duplication of work, confusing document silos, frustrated employees, and exploding costs.
Yet all three frameworks are based on the same fundamental principles of information security. In this article, you will learn how to save valuable time, resources, and stress with a clever multi-framework approach - while simultaneously ensuring your company is fully compliant.
Why multi-framework compliance is essential for your company
If you tackle regulatory requirements in parallel and in isolation, you are burning money. The GDPR protects the rights of natural persons and their data. ISO 27001 protects the confidentiality, integrity, and availability of all your company information. And the NIS2 directive demands the resilience and cyber-robustness of your critical systems, as well as extremely tight reporting processes.
Treating these three topics as separate task packages inevitably leads to redundant processes. An integrated multi-framework approach systematically bundles these requirements. You create a single, stable compliance foundation that is flexible enough to serve each of these standards. This drastically reduces your administrative burden and ensures maximum transparency for auditors and authorities.
The 5 major compliance synergies at a glance
Although the frameworks pursue different protection goals, they have massive overlaps in operational implementation. If you know these intersections, you can bundle them effectively:
1. Integrated risk analysis as the core
Each of these three frameworks requires you to regularly assess your risks. While the focus differs in detail:
- GDPR: Protection of the rights and freedoms of data subjects.
- ISO 27001: Protection of all information technology assets of your company.
- NIS2: Protection of the availability and security of systems to maintain operations.
Your practical solution: Don't let your team start three different risk analyses. Establish a single, unified risk assessment method. Centralize your IT asset inventory. When performing the subsequent assessment, simply check against three separate columns or categories: What impact does an incident have on data protection (GDPR), our business (ISO), and critical infrastructure (NIS2)? This eliminates redundancies and keeps your data consistent.
2. Consolidate technical and organizational measures (TOMs) effectively
Whether it's access controls for the server room, end-to-end encryption for your laptops, or automated backup concepts: technical security measures are the operational heart of your compliance.
When preparing for an ISO 27001 audit, you describe these measures in minute detail anyway. Leverage this work multiple times: Instead of drafting a new document for technical and organizational measures (TOMs) for the GDPR, simply refer directly to the relevant sections of your ISO security policies in your data protection documentation. This prevents contradictory requirements within the company and saves your IT team a huge amount of time on documentation.
3. Synergies in incident management and supplier auditing
A cyberattack doesn't distinguish between frameworks. If sensitive data is leaked, it immediately affects all three areas.
- The problem: Deadlines collide. The GDPR gives you 72 hours to report a data breach. NIS2 requires an initial early warning to the BSI after an extremely short 24 hours.
- The solution: You need a single, integrated incident response plan. Your internal emergency manual must be structured so that when an incident is detected, the strictest deadline (the 24-hour NIS2 deadline) automatically sets the pace. If personal data is also involved, the GDPR notification simply runs within the same workflow.
The same applies to your suppliers: build a standardized security questionnaire for your service providers. A cloud provider has to answer questions about data protection (GDPR) and information security (ISO/NIS2) anyway. Request this data in a single process.
4. Training and awareness as a cross-functional topic
Employee awareness is your company's most important line of defense. Phishing emails affect data protection just as much as network security.
Don't send your team to three separate training sessions. Design a central, modular training concept. In a combined e-learning course, your employees learn in just a few minutes how to create secure passwords (ISO), how to recognize phishing (NIS2), and how to handle customer data in compliance with the law in their daily work (GDPR). This reduces administrative effort and drastically increases acceptance among the workforce.
Digital tools for your integrated compliance management
Anyone still trying to manage multi-framework compliance with confusing folder structures and manual lists has already lost in the modern regulatory jungle. The manual effort will eat up your resources.
Modern compliance management software is designed precisely for this kind of integrated control. Platforms like heyData offer you the ability to consolidate your requirements from GDPR, ISO 27001, and NIS2 into a single, centralized system:
- You link a security measure (e.g., MFA) once in the system and automatically satisfy the requirements of all three frameworks.
- You assign tasks across departments and maintain a clear overview of your current compliance status at all times via a central dashboard.
- You generate comprehensive audit documentation efficiently at the push of a button, without having to painstakingly hunt down documents.
This reduces redundant work to an absolute minimum and turns compliance into a scalable process.
Bottom line: Leverage the synergies before bureaucracy slows you down
Implementing GDPR, ISO 27001, and NIS2 simultaneously is undoubtedly a mammoth task for small and medium-sized enterprises. But if you open your eyes and view the massive overlaps as an opportunity, you can drastically reduce the total effort involved.
Integrated multi-framework management, supported by a smart software solution, prevents the creation of costly silos. You avoid duplication of effort, take the pressure off your IT department, and build a future-proof compliance system that protects your company while securing a clear competitive advantage in the market.

FAQ
Can I use an ISO 27001 certificate as proof of my NIS2 compliance?
Can I use an ISO 27001 certificate as proof of my NIS2 compliance?
ISO 27001 is the best possible foundation and perfectly covers the majority of NIS2’s technical requirements. However, the certificate is not an automatic “free pass.” Specific legal obligations under NIS2 - such as registration on the BSI portal, the extremely short 24-hour reporting deadlines, and the management’s personal training and liability obligations - must be addressed separately as part of a gap analysis.
What's the best way to start integrating the frameworks?
What's the best way to start integrating the frameworks?
The most efficient starting point is to consolidate your risk analysis and asset inventory. By establishing a standardized method for assessing threats to your IT infrastructure, you can address data protection and information security requirements all at once. In the second step, compile your technical and organizational measures (TOMs) into a single, centralized list.
Isn't multi-framework compliance much more expensive than evaluating the frameworks individually?
Isn't multi-framework compliance much more expensive than evaluating the frameworks individually?
In the short term, setting up an integrated system requires a bit of planning effort. In the long term, however, you’ll save a massive amount of time and money. You’ll need to license fewer software tools, prevent costly duplication of work within your teams, and ensure that audits run much faster and more smoothly. Avoiding fines or the loss of major clients will pay for the investment extremely quickly anyway.
Do smaller companies also have to comply with all three frameworks at the same time?
Do smaller companies also have to comply with all three frameworks at the same time?
The GDPR applies to every company without exception. Whether you’re subject to NIS2 depends on your industry and the size of your company (generally 50 or more employees or 10 million euros in revenue) - or on whether your B2B customers pass these requirements on to you. ISO 27001, on the other hand, is often a strategic decision aimed at winning major clients. If you anticipate that two or more of these standards will be relevant to you, you should plan for an integrated approach from day one.
