IT-Label versus ISO 27001: the difference explained

Modern organizations run almost entirely on digital systems. Cloud applications, hybrid workplaces, video conferencing, access control, sensors and increasingly AI applications have become part of daily reality. All these systems share a common requirement: a reliable digital environment in which they can function.

In practice, cybersecurity is often seen as a task for the IT department. Policy, passwords, backups and access rights are arranged there. But there is a part of the story that receives less attention: the physical environment. A building provides the connectivity, the cabling, the technical rooms and the network facilities on which an organization's digital systems ultimately depend.

This raises a logical question. How does an established standard such as ISO 27001 relate to the IT-Label? Both concern digital resilience, but they look at different things. In this article we explain the difference and show why the two actually reinforce each other.

What is ISO 27001?

ISO 27001 is an international standard for information security management systems, abbreviated as ISMS. The standard describes how an organization systematically sets up, controls and improves the security of information. It is therefore not about isolated technical measures, but about a coherent management system.

The standard focuses, among other things, on the following components:

• policy and procedures around information security;
• risk analyses and the management of risks;
• access management to information and systems;
• incident management and dealing with data breaches;
• awareness and training of employees;
• continuous improvement of information security.

The core is easy to summarize: ISO 27001 assesses how an organization organizes and controls its information security. An organization that meets the standard demonstrates that it has set up processes and measures to manage information safely. The emphasis lies on the organization, its people and its working methods, not on the building in which it is housed.

What is the IT-Label?

The IT-Label looks at a different question: the digital quality of the building itself. Instead of assessing how an organization works, the IT-Label makes visible which technical IT foundation is present within a building. Anyone who wants to understand exactly what is being assessed can find more on the page about what the IT-Label is.

The classification looks at facilities that determine whether a building can support modern digital applications, including:

• internet connectivity and available connections;
• fiber optic facilities in and to the building;
• network cabling and its quality;
• WiFi infrastructure and coverage;
• patch rooms and technical rooms;
• redundancy in connections and power supply;
• climate control of technical rooms;
• monitoring and physical access security of equipment;
• the possibilities for future digital applications.

Here too, the core can be stated briefly: the IT-Label does not assess an organization's cybersecurity, but the digital readiness of the building. It is not a legal certification and not a mark of quality with legal status, but an independent classification methodology that makes the digital foundation of real estate transparent. The outcome is expressed in a classification ranging from IT1+ PREMIUM to IT5 SHELL.

Even the best security policy runs aground on a building that cannot handle the connection. Digital resilience needs both an organization and a foundation.

The difference between ISO 27001 and the IT-Label

The two instruments are sometimes mentioned in the same breath, but they assess fundamentally different things. The comparison below makes this clear.

	ISO 27001	IT-Label
Focus	Organization	Building
Subject	Information security management	Digital infrastructure
Assessment	Processes, policy and risks	Technical facilities
Responsible party	Organization and IT department	Property owner, developer, manager
Purpose	Protecting information	Making digital quality visible

Where ISO 27001 takes the perspective of the using organization, the IT-Label takes the perspective of the building. Responsibility lies with different parties. An IT manager can have security well organized without having any influence on the fiber optic connection running to the building. A property owner can put the infrastructure in order without knowing anything about the tenant's security policy.

Why do ISO 27001 and the IT-Label reinforce each other?

Precisely because they look at different components, the two instruments complement each other. Take a concrete example. An organization can work fully in accordance with ISO 27001, with a tight security policy, trained employees and clear incident procedures. But that same organization can be located in a building with limited network capacity, outdated cabling or without redundant connections.

In that case, the policy is excellently organized, but daily practice runs aground on the physical foundation. If a single internet connection fails and there is no second route, systems come to a standstill, no matter how well the security policy is drawn up. We describe the importance of a dual route in more detail in our article on network redundancy.

Good information security therefore requires two things at once: a well-organized security policy and a reliable digital infrastructure. One cannot function without the other. In short: ISO 27001 determines how an organization organizes its digital security, and the IT-Label makes visible the digital foundation on which that organization operates.

Why this matters increasingly for real estate

Dependence on digital infrastructure is growing at a pace that few buildings can keep up with. Several developments reinforce each other and raise the standards for buildings.

Developments raising the bar

• hybrid working, in which stable connections and good WiFi coverage have become preconditions;
• the growth of cloud use, which makes almost every action dependent on connectivity;
• AI applications, which move large amounts of data and are sensitive to faltering connections;
• smart buildings with sensors, access systems and climate control that run on the network;
• stricter requirements and expectations around cybersecurity;
• an increasing dependence on stable, redundant connectivity.

As a result, digital quality is increasingly becoming part of a building's overall quality. Just as the energy label has had a fixed place in building assessment for years, a similar need for insight into the digital foundation is now emerging. We explored this parallel in the article on the IT-Label versus the energy label, and further in the exploration of smart building technology.

For property owners, this is relevant because the digital readiness of a building factors into tenants' choices. For tenants, it is relevant because they want to know in advance whether their way of working suits the building. Anyone orienting themselves as a user can find practical points of attention on the page about what to pay attention to.

Digital security requires collaboration

The IT-Label does not replace standards such as ISO 27001. Both instruments have their own, clearly defined role. ISO 27001 provides insight into how organizations secure their information. The IT-Label provides insight into what digital foundation a building offers. They do not conflict, they complement each other.

Together they provide more transparency, better choices and more future-proof commercial real estate. An organization that takes its information security seriously would do well to also know on what foundation that security rests. And a real estate party that makes the digital quality of a building transparent gives tenants and investors the information they need.

Would you like to know which classification fits your building and how the assessment works? Take a look at how the IT-Label works, so you can make the digital foundation of your real estate visible in the same clear-headed way as the security policy of the organizations working there.
