Penetration testing and Vulnerability analysis
Test your IT Systems against hacker attacks
Identify security gaps before others do – with a comprehensive assessment of your systems by our experts.
Our penetration test simulates real-world attacks and uncovers potential vulnerabilities in your IT infrastructure. This allows you to take proactive steps, close security gaps, and protect your data and networks from cyber threats. Trust our expertise to elevate your IT security to the next level and minimize long-term risks.

What is Penetration testing?
Your protection against cyber attacks
A penetration test, often referred to as a Pentest, is a targeted security assessment in which IT experts test the resilience of your systems through controlled attacks, simulating intrusion and manipulation attempts. The same tactics, techniques, and procedures used by hackers and cybercriminals to gain unauthorized access to IT systems are applied during this process.
To effectively protect your IT infrastructure, a highly skilled team of security experts, penetration testers, incident response specialists, forensic investigators, malware analysts, and security researchers is required. Thanks to our partnerships with leading industry experts, we offer comprehensive vulnerability assessments and can secure your systems against potential threats. Annually, our partners perform over 2,500 successful penetration tests, strengthening the IT security of numerous companies.
Regular penetration testing
Your protection against undetected security gaps
A penetration test should ideally be conducted once a year to identify and address overlooked or hard-to-detect vulnerabilities in your IT systems. Cyber threats are constantly evolving, with new attack methods emerging regularly. Regular testing helps keep your security measures up to date and allows you to spot potential risks early, before they can be exploited by attackers.
By proactively identifying and closing these gaps, you ensure that you’re always one step ahead, keeping your IT infrastructure optimally protected against cyberattacks. Trust in an annual penetration test to continuously ensure the security of your systems and minimize long-term risks.

White box penetration test – detailed security analysis for your systems
A white-box penetration test provides an in-depth security analysis of your IT systems, giving testers full access to documents and source code. During the test, our experts work closely with your developers to improve code quality and increase security.
The test requires a comprehensive overview of the network infrastructure to enable efficient analysis. The time required to analyse the code varies depending on the complexity of the project.
This test is ideal for companies that want to identify internal security gaps and improve the quality of their code in the long term. Compared to the black box test, where less information is available, the white box approach offers a more precise analysis and targeted security improvements.
Grey box penetration test – combined analysis for deeper insights
The grey box penetration test offers a balanced solution between external and internal attacks. Testers receive specific information in advance, such as user credentials or network infrastructure, in order to identify vulnerabilities more quickly without having to access confidential data.
This test is more time-efficient than a white-box pentest and is suitable for quickly and thoroughly analysing applications and IT infrastructures. It offers companies a realistic and effective security check to recognise risks and rectify them quickly.
Black box penetration test – Realistic protection against external threats
A black box penetration test simulates a real hacker attack in which the testers have no information about the system to be tested other than the domain or IP address. This approach enables the identification of vulnerabilities that could remain undetected during normal operation.
At the beginning of the test, the testers have to gather information on their own, which takes a few working days. The test provides valuable insights into how an external attacker could penetrate your system.
A black box penetration test should be carried out at least once a year to ensure optimal protection against external threats.
5 reasons for a penetration test
Hackers use these methods to penetrate online shops
Online shops are a favourite target of hackers, especially in the e-commerce sector. Inadequate security measures can allow attackers to penetrate payment systems, steal customer information or manipulate transactions. Cyber criminals often use vulnerabilities such as insecure applications, weak passwords or outdated security protocols to gain unauthorised access to sensitive data.
A regular penetration test helps to identify these security gaps at an early stage and to secure your online platform in a targeted manner. This ensures that you are always one step ahead of attackers and that your data and IT systems remain optimally protected.
Protect your company proactively – with a professional penetration test and prevent your online shop from becoming a target for cyber criminals.
