What is Penetration Testing?
Penetration testing, also known as ethical hacking or pentest, is an authorized simulated cyber attack on your computer systems, networks, or web applications. The primary goal is to identify security vulnerabilities that could be exploited by attackers.
While a vulnerability scan only detects known vulnerabilities, a pentest goes much further. Our security consultants think and act like real hackers: they combine automated tools with manual techniques, look for business logic flaws, actually attempt to exploit found vulnerabilities, and chain multiple small issues together into complete attack chains.
The result? A realistic picture of your actual risk. Not a theoretical list of possible problems, but proof of what an attacker could actually achieve.
At JamaSec, we combine 20+ years of IT experience with state-of-the-art security expertise.

Frequently Asked Questions about Penetration Testing
Answers to the most frequently asked questions about our pentest services
What exactly is penetration testing and why is it important?+
Penetration testing (also called pentest or ethical hacking) is a controlled, simulated cyberattack on your IT systems, networks, or applications. The goal is to discover vulnerabilities before real hackers do. A pentest is important because it helps you identify security weaknesses, meet compliance requirements (such as NIS2, ISO 27001, PCI-DSS), and improve your overall security posture.
How long does a penetration test take?+
The duration varies depending on scope and complexity. A standard web application test takes on average 5-10 working days. An extensive infrastructure pentest can take 2-4 weeks. Enterprise environments may take even longer.
What is the difference between black box, white box, and gray box testing?+
In black box testing, the tester has no prior knowledge - this simulates an external attacker. In white box testing, the tester has full access to source code and documentation. Gray box testing is the golden middle with limited information. We usually recommend gray box for the best balance.
What methodology do you use?+
We use industry-standard frameworks: OWASP Testing Guide for web applications, PTES for infrastructure, and MITRE ATT&CK for real-world attack scenarios. Our approach combines automated scanning with extensive manual testing.
What do I get in the pentest report?+
Our report includes: Executive Summary for management, technical details with screenshots and proof-of-concept, CVSS risk scores, concrete remediation recommendations, a prioritized action roadmap, and overview of tested systems.
Do you offer retesting?+
Yes, every pentest includes one free retest within 3 months as standard. We validate whether all critical and high-risk findings have been correctly resolved and not reintroduced.
What does a penetration test cost?+
Our prices are transparent. A basic web application pentest starts from 3,500 euros. Infrastructure pentests start from 5,000 euros. Mobile app testing starts from 4,000 euros. Use our Pentest Calculator for an indication.
How often should I have a pentest performed?+
We recommend at least annually for business-critical systems. Also after significant changes such as major releases or infrastructure migrations. Many compliance frameworks require periodic testing.
Can you test production environments?+
Yes, we are experienced in safely testing production environments. We follow strict protocols to minimize disruption and have direct communication lines for any issues.
What is the difference between a vulnerability scan and pentest?+
A vulnerability scan is automated and detects known vulnerabilities. A pentest goes further: our ethical hackers actually attempt to exploit vulnerabilities and look for business logic flaws.
What certifications do your pentesters have?+
Our consultants hold certifications such as OSCP, OSWE, OSEP, CEH, GPEN, GWAPT, CREST CRT/CCT, and CISSP. Several team members have experience with bug bounty programs.
Is a pentest sufficient for NIS2 compliance?+
A pentest is an important component but not sufficient on its own. NIS2 requires a holistic cybersecurity framework. We recommend combining a pentest with a broader NIS2 gap analysis.
