Product security does not depend solely on its user interface. Risks can arise in APIs, cloud configurations, mobile applications, internal networks, device firmware or artificial intelligence systems. We therefore test individual technologies as well as entire interconnected ecosystems.
We test the security of AI applications, chatbots, AI agents and RAG systems. AI penetration testing assesses resilience against prompt injection, jailbreak attacks, sensitive data leakage, model manipulation and misuse of external tools according to the OWASP Top 10 for LLM Applications.

Learn about OT system testing
We assess whether vulnerabilities in your technologies can be exploited and determine the potential impact of a successful attack. Learn how penetration testing works, when to perform it and what types of tests we provide.
Learn about pentesting

Modern products connect applications, APIs, cloud services and infrastructure. A weakness in one component can expose sensitive data or other systems, so we test both the technologies and their connections.
Define the scope of security testing
You may know which product or system you want to assess, but its security often depends on additional components. A web or mobile application may be connected to APIs, cloud services, internal infrastructure, user accounts or third-party services. If any of these components are excluded, an attack path may remain undetected.
Discuss the scope of testing
Testing can also include Wi-Fi networks, VPNs and remote access, Active Directory, servers, databases, network devices, privileged accounts, network segmentation and industrial OT, ICS and SCADA systems.
Before the project begins, we map the solution architecture, data flows, user roles, external integrations and key risks. We then determine:
The result is a testing scope that reflects your architecture, risks and available resources.
The exact process depends on the technology, project objectives and selected type of testing. Together, we define a scope that reflects the solution architecture, real-world risks and your security requirements.
01
We identify applications, APIs, cloud services, infrastructure, devices, user roles and external integrations. We map their connections and data flows to understand the entire technology environment and ensure that important components are not overlooked.
02
Together, we determine what the testing should assess, which systems and data are most important and what impact their compromise could have. We consider critical processes, potential attack scenarios, regulatory obligations and your business priorities.
03
Based on the technology, identified risks and desired outcome, we recommend the most appropriate assessment. This may include penetration testing, a configuration or security audit, AI testing, social engineering or comprehensive Red Teaming combining multiple attack methods.
04
Our ethical hackers assess selected technologies, configurations and security controls. We combine automated tools with manual testing and realistic scenarios to uncover vulnerabilities and attack paths that a standard scan may not detect.
05
We present the results in a clear format tailored to the type of testing. We explain the identified risks, determine their severity and recommend specific measures. Depending on the project scope, we can also verify the effectiveness of implemented fixes.
Security testing should not begin only after an incident. Vulnerabilities can arise during development, updates, architectural changes or the connection of a new service. Timely testing helps uncover them before they threaten users, sensitive data or business operations. We particularly recommend testing:
Testing before launch helps uncover vulnerabilities before customers or employees begin using the system. Fixes can usually be implemented faster and at a lower cost at this stage.
New features and code changes can introduce vulnerabilities into a previously secure application. Testing verifies whether the update has affected authentication, permissions, data processing or communication with other systems.
System relocation, network architecture changes or cloud migration can lead to misconfigurations and unintentionally exposed services. Testing assesses the new environment and its connections to existing infrastructure.
A new API, external integration or third-party service expands the attack surface. We assess access controls, communication security and risks arising from connections between individual systems.
AI applications, chatbots, agents and RAG systems may be vulnerable to prompt injection, data leakage or misuse of connected tools. Testing helps identify these risks before the system becomes available to users.
Device security depends on hardware, firmware, communication interfaces, applications and cloud services. Early testing makes it possible to address vulnerabilities before manufacturing or distribution begins.
Following an attack or suspicious activity, it is important to verify that the cause of the incident has been removed and that no additional attack paths remain. Testing also helps assess the effectiveness of newly introduced measures.
Security testing can identify technical weaknesses that could affect the outcome of an audit or certification. It can also provide evidence of the effectiveness of selected security controls.
Technologies, threats and attacker techniques are constantly evolving. Regular testing helps identify new vulnerabilities and confirms whether existing security controls remain effective.
Legislation, security standards and customer requirements increasingly demand regular assessment of technologies and implemented security controls. Depending on the specific obligations, a penetration test, security audit, configuration review or more comprehensive resilience testing may be appropriate.
Discuss your testing requirements
Specific requirements depend on the type of organisation, product, technologies used and regulatory status. Testing results can provide technical evidence of the security level and effectiveness of implemented controls. However, they do not replace legal assessment or a comprehensive compliance audit.
We tailor the deliverables to the type of testing, technologies used and project objectives. You will receive more than a list of findings. We also explain their context and potential impact and provide specific recommendations for both technical teams and management.
01
We document identified vulnerabilities, misconfigurations and weaknesses in security controls. Each finding includes supporting evidence, a severity rating and the technical information required to understand and resolve it.
02
We explain how individual weaknesses can affect the security of the entire solution. Where relevant, we also demonstrate how an attacker could combine them and what level of access to systems or data they could achieve.
03
Management receives a clear overview of the most important findings, their potential business impact and recommended priorities. The summary supports informed decision-making without requiring detailed technical knowledge.
04
For each relevant finding, we recommend specific steps to reduce the risk or remove the vulnerability. We tailor our recommendations to the tested technologies, solution architecture and capabilities of your technical team.
05
Our experts present the results, explain their context and answer your questions. We help you prioritise remediation and, depending on the project, can verify whether the recommended measures have been implemented correctly.
We apply experience from penetration tests, audits and Red Teaming when assessing different technologies. Automated tools are complemented by manual testing to uncover hidden vulnerabilities and attack paths.

We assess the security of web and mobile applications, APIs, cloud environments, infrastructure, AI, IoT devices and industrial OT, ICS and SCADA systems. Based on your objectives, we select the most appropriate type of testing, audit or Red Teaming exercise.
We complete more than 600 security projects each year. In 2025, we identified 3,293 findings, and our experts have been credited with more than 20 CVEs. We verify every finding, explain its impact and recommend a specific solution.
The most important insights from our real-world projects are available in our free Ethical Hacker Report.
Answers to the most common questions about tested technologies, defining the right scope, the security testing process and its results.
Start with systems whose compromise would have the greatest impact on operations, customers or sensitive data. These are typically publicly accessible applications, APIs, cloud services, remote access points or critical internal infrastructure. If you are unsure, we can help you prioritise based on your architecture and risks.
Yes. A web or mobile application may be connected to APIs, cloud services, internal infrastructure or external systems. Testing multiple technologies together also helps identify vulnerabilities at their interfaces and potential attack paths across the entire solution.
Not always. We can test without access to the source code from the perspective of an external attacker. If you provide the code, we can better understand the application and focus on vulnerabilities that may be more difficult to uncover during standard external testing.
Yes, provided the testing can be performed safely and without creating an unreasonable operational risk. We define permitted methods, testing times, contact persons and excluded systems in advance. For sensitive technologies, we can use a test environment or limit the scope.
Some testing techniques can increase system load or trigger unusual behaviour. We therefore assess the risks in advance and adapt the testing to the sensitivity of the environment. We do not perform potentially disruptive actions without approval and use a more cautious approach for critical systems.
The duration depends on the type of technology, size and complexity of the environment, required testing depth and available documentation. A smaller test may take several days, while a more extensive project may require several weeks. We provide an accurate estimate after the initial consultation and scope definition.
The frequency depends on the level of risk, pace of change and regulatory requirements. We recommend regular testing and reassessment after a major update, architectural change, connection of a new service or security incident.
Yes. After remediation, we can verify whether the vulnerabilities have been removed correctly and whether the implemented changes have introduced any additional security risks. The retest provides an updated status for each finding.
During the initial consultation, we review the technologies, their connections, sensitive data, key risks and the desired outcome. Based on this information, we recommend a penetration test, security audit, configuration review, Red Teaming exercise or a combination of approaches.
A penetration test practically verifies whether vulnerabilities can be exploited and what impact a successful attack would have. A security audit focuses primarily on configurations, implemented controls and compliance with the requirements of a selected methodology or standard.
Red Teaming is suitable when you want to assess the resilience of the organisation as a whole rather than the security of a single technology. It simulates the methods of a real attacker and may combine digital attacks, social engineering and physical intrusion. It also assesses whether the security team can detect, stop and manage the attack.
