Pentest – Professional Penetration Test

Pentest – Professional Penetration Test

Pentest – Professional Penetration Test

A pentest (penetration test) involves simulating a controlled cyberattack in order to identify vulnerabilities that are actually exploitable in your information system. Unlike a simple automated scan, a penetration test reproduces the behavior of a determined attacker: reconnaissance, exploitation, privilege escalation, lateral movement, and potential exfiltration.



At De Shagan Network, our pentests are carried out according to recognized methodologies (ANSSI, OWASP, NIST) and aligned with the best practices of the PASSI framework, while remaining independent of any official certification.

Identify exploitable vulnerabilities

Identify exploitable vulnerabilities

Detect vulnerabilities that an attacker can actually exploit, beyond simple automated scans.

Measure business impact

Measure business impact

Assess the concrete consequences of a breach: access to sensitive data, business interruption, damage to reputation.

Strengthen your compliance and resilience

Strengthen your compliance
and your resilience

Adopt an approach aligned with regulatory requirements (NIS2, ISO 27001, DORA, GDPR) and sustainably improve your cybersecurity posture.

Different types of pentests, to assess your actual level of security

Different types of pentests, to assess your actual level of security

Each organization has a different attack surface: Internet exposure, internal architecture, business applications, users.

DE SHAGAN NETWORK offers a complete range of penetration tests to simulate realistic attack scenarios, identify exploitable vulnerabilities, and sustainably strengthen your cyber posture.

Infrastructure penetration testing

Infrastructure penetration testing

Infrastructure penetration testing assesses the security of your networks, servers, security devices, and Active Directory environments. It simulates a technical attack designed to exploit configuration flaws, system vulnerabilities, or architectural errors. The goal is to measure an attacker’s ability to compromise your information system and move laterally.

Application penetration testing

Application penetration testing

Application penetration testing provides an in-depth analysis of the security of your web, mobile, and API applications. It includes the identification of OWASP vulnerabilities (SQL injections, XSS, authentication flaws, session management issues, etc.) as well as advanced robustness and business logic testing. The goal is to identify exploitable weaknesses that could lead to a compromise or data breach.

Internal penetration testing & lateral movement

Internal penetration testing reproduces the scenario of an attacker who has already compromised a workstation or user account. It aims to test privilege escalation, Active Directory compromise, and lateral movement to critical systems. The goal is to assess your resilience against a deep, multi-stage attack.

External penetration testing

External penetration testing

External penetration testing simulates an attack launched from the Internet against your exposed services: websites, VPNs, access portals, and public servers. It helps identify entry points accessible to an attacker and assess your digital exposure surface. The goal is to reduce the risks associated with your external visibility.

Are you really prepared for an attack?

Cyberattacks don’t come with a warning. A pentest reveals what an attacker could compromise today: sensitive data, administrator access, business continuity. Anticipate the risk before it becomes an incident.
