Selecting a Penetration Testing Provider
Penetration Testing Approaches
The penetration tester receives a minimum amount of information
Simulation of an attack carried out by an intruder
Without prior knowledge of the targets
Simulation of an attack carried out by an authorized employee
or with partial knowledge of the infrastructure/applications
The penetration tester has some information (e.g., username/password)
The penetration tester has extensive knowledge of the
infrastructure and applications as potential targets.
Penetration Testing Costs
The cost of a penetration test depends on the effort required (in person-days), the type of penetration test (black-box, gray-box, or white-box), and the complexity, which can vary greatly from case to case. For this reason, reliable price estimates can only be provided after an initial scope assessment.
To provide a rough framework, approximately 53% of our penetration tests range from 5 to 10 person-days (PD) and cost between 3,000 euros and 18,000 euros.
Reporting - Sample Report
For the executive board, the CISO, and cybersecurity experts alike, our penetration test reports are of the highest standard in terms of both presentation and content. For each penetration test, you’ll receive a professional report that you can forward directly to your annual auditors or regulators.
Our sample report provides you with a comprehensive overview of the structure, scope, level of detail, and professionalism you can expect when you hire us to conduct a penetration test.

Penetration Testing Quote
Please answer a few questions so we can provide you with a quote. Reputable penetration testing providers absolutely require this information, as the scope of work cannot be determined otherwise. Be careful not to accept flat-rate quotes for manual penetration tests.
Penetration Testing Guidelines & Standards
Our experts have extensive experience working with auditors and regulators from around the world, which is why we know exactly what matters.
Whether it’s BSI Basic Protection, ISO 27001, BAIT, VAIT, the IT Security Act, or KRITIS 2.0, DORA, KWG, MaRisk, GDPR, or BDSG—to meet all legal and regulatory requirements, regular penetration tests (at least on your externally accessible systems) are absolutely essential. Our penetration tests meet all requirements and standards.
We conduct our penetration tests in accordance with BSI guidelines as well as the internationally recognized penetration testing standards OSSTMM, OWASP, NIST, PTES, and ISSAF.
Experience
We have extensive experience in ensuring that your systems remain intact despite in-depth penetration tests and that your operations are not unnecessarily disrupted.
Our penetration tests also utilize tools and exploits (zero-days) that we have developed ourselves.
We also support you in developing and implementing end-to-end processes for penetration testing. This includes mitigation consulting and assistance with risk acceptance where appropriate.

Frequently Asked Questions About Penetration Testing
A penetration test checks a defined system for as many vulnerabilities as possible. Red Teaming simulates a real, covert attack using techniques, people, and processes, and assesses whether your team can detect and defend against it. A penetration test evaluates security, while Red Teaming evaluates detection and response capabilities.
The price depends primarily on the scope and depth of the work. It depends on how many and which systems are tested, how thoroughly they are examined, and whether a follow-up test is required. We work with a clearly defined scope rather than vague, arbitrary fixed prices. Give us a call, and we’ll work with you to determine the scope of the work.
Common types include external and internal network penetration tests, web application and API penetration tests, mobile app tests, Wi-Fi/wireless tests, IoT tests, and social engineering. The best combination depends on your infrastructure and compliance requirements.
A focused test usually takes a few days, while extensive network or red-teaming projects can take several weeks. We determine the specific duration during the scoping phase to ensure that the effort and value align with your goals.
We recommend performing this at least once a year, as well as after significant changes to systems or applications. Regulated companies (e.g., under DORA or §44 KWG) may have stricter requirements, which we take into account during the planning process.
Look for recognized industry certifications such as OSCP, OSEP, and OSWE, as well as standardized methodologies (OWASP, PTES, BSI). Our testers are certified accordingly and maintain comprehensive documentation. Suitable for internal audits and regulatory authorities.
Yes. Our tests and reports are designed to meet regulatory requirements—from ISO 27001 to DORA (including threat-based testing according to TIBER-DE) to BaFin’s §44 KWG special audit. You’ll receive audit-ready documentation.
A vulnerability scan is automated and identifies potential vulnerabilities. A penetration test is conducted manually by experts, verifies whether vulnerabilities can be exploited, and assesses the actual risk—including prioritized recommendations for action.
We conduct testing for small and medium-sized businesses, mid-market companies, and large corporations—with particular expertise in banking, insurance, critical infrastructure/energy, healthcare, pharmaceuticals, and manufacturing. We tailor the scope and approach to your specific systems and compliance requirements.
