Creating an IT security concept for companies

Data security is not an add-on — it is business-critical. Digital business models, mobile working and cloud-based processes increase not only efficiency, but also the attack surface for cybercriminals. Added to this is a new level of threat: attacks are increasingly automated and AI-assisted. Phishing, identity misuse and the exploitation of technical vulnerabilities can now be carried out on a large scale and with high precision.

Protecting data therefore safeguards not only trade secrets, but also a company’s ability to operate and the trust of customers, partners and authorities. An effective IT security concept is not a technical formality, but a central component of corporate responsibility.

Two recent cases show how quickly matters can become critical

In autumn 2025, targeted cyberattacks on the central check-in and boarding systems of an international IT service provider caused significant disruption at several European airports, including Dublin and Brussels. At times, passenger handling processes were only partially available, resulting in delays and manual emergency procedures. The incident demonstrated how dependent even critical infrastructure is on functioning IT systems and secure third-party structures, and the consequences that security vulnerabilities along the supply chain can have.

Another case concerns a London-based operator of nurseries in several European countries. Following a cyberattack in 2025, personal data belonging to children, parents and employees was compromised. Alongside data protection consequences, the incident had one outcome above all: a considerable loss of trust among parents and supervisory authorities. Organisations handling particularly sensitive data therefore face the challenge of not only implementing security measures, but also making them transparent and traceable.

Prevention instead of damage limitation

Both cases underline the importance of proactive measures. Companies that establish a robust IT security concept at an early stage can minimise risks and remain able to act in an emergency.

But how can such a framework be created in practice?

1

Analysis: know your IT landscape

An effective security concept begins with a comprehensive inventory. Which systems are in use? Where is particularly sensitive data stored? Who has access — internally and externally? Transparent IT documentation is a prerequisite for every further security measure.

2

Assess and prioritise risks

Not every vulnerability is equally dangerous. A structured risk assessment helps identify critical processes and secure them in a targeted manner — particularly where personal or business-critical data is processed.

3

Implement technical safeguards

Basic protective measures such as firewalls, antivirus software, encryption and two-factor authentication should be standard. The use of intrusion detection systems (IDS) and systematic patch management is also advisable in order to close known security vulnerabilities quickly.

4

Do not neglect organisation and training

A company’s IT security concept is only as strong as its employees. Clear guidelines for using IT systems, password policies and regular awareness training are essential. Social engineering and phishing attacks in particular deliberately target human behaviour.

5

Introduce backup and emergency plans

An emergency can occur despite every precaution. Regular backups, tested recovery plans and an internal crisis communication plan are therefore essential. These measures safeguard operational capability — even under pressure.

6

Comply with legal requirements

Creating an IT security concept also involves observing legal requirements. The GDPR requires personal data to be protected, while additional standards apply depending on the sector. Failure to comply can result in heavy fines and a loss of trust.

IT security is an ongoing process

Creating an IT security concept for a company does not mean defining measures once and leaving them unchanged. It is a dynamic process that must evolve with technological developments and the business model. Regular audits, external expertise and agile security management help protect the company over the long term.

Our tip: use recent incidents as an opportunity to review your own IT security strategy. Seek advice, identify risks at an early stage — and develop a security concept that suits your company. Those who act today avoid costly consequences tomorrow. We will be glad to support you.
