Structures for security in large format
Regular vulnerability scans and penetration tests are the minimum standard today. They provide an up-to-date, holistic picture of IT risks with clear prioritization and continuous monitoring. For many companies, however, implementation quickly becomes time-consuming: Internal teams with a high level of technical responsibility spend a lot of time communicating, coordinating and coordinating various service providers and thus inadvertently end up micromanaging. We take over the entire vulnerability management process – from annual planning to implementation and tracking in the ticket system. This relieves your team, reduces communication effort and ensures consistent, auditable results, while reducing costs by up to 30 percent compared to individual assignments.
Managed pentesting regularly checks your systems for new vulnerabilities – continuously as part of vulnerability scans, manually through penetration tests and through other means of offensive IT auditing
Our solution adapts flexibly – from fast-growing SMEs to the IT landscape of international corporations.
Thanks to well-established processes and experienced teams, we can reliably secure even extensive infrastructures.
Managed pentesting fits seamlessly into existing security and IT processes – without any additional effort.

What result does your Group achieve?
Better test results
Particularly in highly complex, heavily regulated environments with individual IT solutions, switching between several service providers costs valuable time: each new provider must first understand the architecture, processes and special features before any real depth can be achieved in the tests. A permanent partner continuously builds up this knowledge and can fully focus its energy on developing ever better and more realistic attack paths. The result is deeper insights, consistent test quality and significantly more security gain per test cycle.
Relief for your internal IT teams
We take over the process: from the annual criticality assessment of all applications and the annual test plan to the organization and execution of penetration tests, including kick-off planning and operational implementation. In this way, we ensure continuous security and take the pressure off your day-to-day business.
Greater speed in rectification
We enter the identified vulnerabilities into your ticket system. We monitor the time to fix so that critical vulnerabilities are resolved quickly. We support your developers with targeted advice and practical technical recommendations.
Compliance & auditability
Thanks to structured reports, audit-proof documentation and the integration of common standards (e.g. ISO 27001, DORA, NIS-2), you are optimally prepared for internal and external audits. Once a year, we have our work with you randomly checked by a market companion – so you know for sure that everything is running smoothly.
Difference to the classic pentest - methodically and strategically.
