What a hacker would find, we find first — before any damage is done
Ethical hacking for maximum security
Controlled attack simulations by certified ethical hackers — web apps, networks, cloud and social engineering.
Anonymized reference caseFinancial services provider · Frankfurt, 45 employees+
Starting point
Annual pentest required by BaFin (German Federal Financial Supervisory Authority), web application with customer data, no previous security test.
Solution & result
Black-box pentest of the web app according to the OWASP Testing Guide, internal network pentest, social engineering test with a phishing campaign.
22 findings (4 critical, 8 high, 10 medium) — including an SQL injection that had exposed customer data. All fixed, BaFin evidence provided.
Attackers know your systems better than you do — until the attack
- Real hackers exploit exactly the gaps your team considers unlikely — pentests show what is really vulnerable
- SQL injection, IDOR and misconfigured APIs are not reliably found by scanners — only by manual testing from experienced testers
- NIS2, PCI DSS and cyber insurers require regular penetration tests with documented findings and remediation
A controlled attack by certified ethical hackers — with a full report
- OSCP-certified testers with real attack experience — not an automated scanner report, but manual, creative testing
- Complete kill-chain documentation: from the first gap to potential data access — so your management understands the risk
- Remediation support and a free retest after 60–90 days — we make sure the gaps are really closed
Scope of services
What Penetration Testing (Pentest) does for you
Black-Box Test
Attack simulation without prior information — exactly as a real attacker would proceed.
Web App Pentest
Comprehensive security testing of web applications according to the OWASP Testing Guide and WSTG.
Network Pentest
Penetration tests of internal and external network infrastructure, including lateral movement.
Cloud Pentest
Security testing of your Azure, AWS or Google Cloud environment for misconfigurations.
Social Engineering
Phishing campaigns and vishing tests to assess the human security factor.
Detailed Report
Management summary and detailed technical report with CVSS scores and proof of concept.
Approach
How we work
Scoping & Authorization
Definition of the test scope and objectives, and obtaining written authorization for all tests.
Attack Simulation
Penetration tests carried out by certified ethical hackers (OSCP, CEH).
Evaluation
Preparation of the final report with management summary and technical details.
Retest
Optional retest after the vulnerabilities are fixed to verify the measures.
The pentest found an SQL injection in our customer portal that had been there since launch. An attacker would have had access to all customer data. Clouderio found and fixed it before anyone else did.
Attack Methodology
We think like an attacker —
to protect you better
Our testers follow the same kill chain as real attackers. That is the only way to find vulnerabilities that automated scanners miss.
Reconnaissance
OSINT, footprinting, enumeration — gathering all publicly available information
Scanning & Enumeration
Identifying ports, services, versions, and vulnerabilities
Exploitation
Actively exploiting discovered vulnerabilities — controlled and documented
Post-Exploitation
Lateral movement, privilege escalation — how far can an attacker get?
Reporting & Remediation
Complete documentation, CVSS scores, remediation guidance
Pentest Types
Which pentest is right for you?
In a scoping call, we determine which approach best fits your systems and goals.
Black Box
No prior knowledge — just like an external attacker. Maximum realism, highest effort.
Duration: 5–10 days
Ideal for: External infrastructure, web apps
Grey Box
Credentials and structural knowledge provided — simulates compromised accounts or insiders.
Duration: 3–7 days
Ideal for: Internal systems, cloud environments
White Box
Full access to code and architecture — maximum depth, code analysis included.
Duration: 5–15 days
Ideal for: Critical applications, SDLC
Report Deliverables
Two reports. Two audiences.
Management and the IT team need different information. You get both — plus a free retest.

Everything you need to know about Penetration Testing (Pentest) at a glance.
01How much does a penetration test cost?+
A web app pentest for a mid-sized application starts at a fixed price of €4,500. Complete infrastructure pentests (network + applications) range from €8,000–25,000 depending on scope. After the scoping call, you receive a binding quote.
02What is the difference between a pentest and a security audit?+
An audit evaluates configurations, policies and vulnerabilities — it asks "are there gaps?". A pentest simulates a real attack and shows how far an attacker can get — it answers "what can an attacker do with these gaps?". For complete security, we recommend both.
03What certifications do your testers hold?+
Our testers hold OSCP (Offensive Security Certified Professional), CEH (Certified Ethical Hacker) and GPEN (GIAC Penetration Tester) certifications. All tests are carried out and overseen by at least one OSCP-certified senior tester.
04Do operations have to be interrupted during the pentest?+
No. Pentests can be carried out during normal operations — we schedule sensitive tests (e.g., load tests) for maintenance windows outside core hours. Exploits that could crash systems are always agreed with you in advance.
05What do I receive as a result?+
Two reports: (1) a management summary for executive management and the board — risks in plain language. (2) A detailed technical report for your IT team — all findings with CVSS score, proof of concept, step-by-step description and a concrete remediation recommendation. Both reports are suitable for BaFin, NIS2 and insurers.
06How often should a pentest be carried out?+
Recommendation: at least once a year for core infrastructure, after every major release for web applications, and after infrastructure changes (cloud migration, new locations). NIS2 and PCI DSS require regular testing — we advise you on the optimal frequency for your industry.
