Identify and fix your vulnerabilities before an attacker does.
Our penetration tests analyze the security of your information system and identify critical vulnerabilities.
Our penetration testing assesses the IT security of your applications, infrastructure, and systems. We analyze IT environments to accurately measure the level of security against current threats. Pentests aim to detect security vulnerabilities before they are exploited by hackers. Each engagement includes a security audit and supplementary security audits to cover the entire perimeter. We evaluate system and information systems security to identify critical vulnerabilities. Authentication controls are tested to prevent access bypasses and strengthen system security. The tests protect sensitive data by validating protection mechanisms and confidentiality processes. Our scenarios replicate real-world cyberattacks to measure the resilience of the IT system and its resistance to hacking. Pentesting allows you to anticipate hacking risks and establish appropriate security measures. We help formalize an IT security policy and clear operational rules for your teams. The reports identify cybercrime risks and suggest ways to reduce exposure. The service integrates risk management to prioritize remediation based on business impact. We audit the IT system, APIs, and exposed services to detect attack vectors. Technical recommendations include encryption and cryptography to protect communications and databases. We test the strength of passwords, authentication policies, and identity management mechanisms. Penetration testing assesses information security and the compliance of confidential data processing. Our tests simulate malicious behavior and attacks to refine your defenses. The approach covers the digital security of applications, infrastructure, and connected devices. We offer tailored security solutions (WAF, hardening, network segmentation) to reduce the attack surface. The results highlight the protection of confidential information and the actions required to secure it. The process includes the detection and management of security incidents to improve operational responsiveness. Our teams of security experts conduct advanced hacking analyses to replicate real-world tactics. Penetration testing activities cover ethical hacking, vector identification, and remediation. Each report prioritizes IT risks and proposes a concrete action plan to prevent future cyberattacks.
Why do a penetration test?
Identify vulnerabilities that can be exploited by cybercriminals before it's too late.
Assess your company's exposure to an internal or external attack.
Test the robustness of your web, mobile and IoT applications.
Prioritize patches based on detected vulnerabilities.
Approaches to penetration testing
Penetration tests rely on different approaches to assess the security of an IT system against simulated attacks. Each method aims to identify specific system vulnerabilities by reproducing various attack scenarios to meet precise security objectives. Depending on the approach chosen, the test can reveal different weaknesses and offer a complementary view of the organization's security level. Understanding these approaches is essential for adapting cybersecurity strategy and strengthen the protection of information systems against current threats.
Black box, grey box, white box: what are the differences?
The choice between black box, grey box and white box depends mainly on the level of information the auditor has on the target system, and the type of attack one wishes to simulate.
Black Box
In this approach, the auditor has no prior access to or information about the system configuration, web applications, or infrastructure being tested. They act as an external hacker, seeking to exploit vulnerabilities visible from the outside. This type of penetration test is ideal for assessing security against attackers with no internal knowledge and allows for measuring the system's robustness against opportunistic or targeted attacks.
Furthermore, the auditor has no prior access to or information about the system configuration, web applications, or infrastructure being tested. They act as an external hacker, seeking to exploit vulnerabilities visible from the outside. This type of penetration test is ideal for assessing security against attackers with no internal knowledge and allows for measuring the system's robustness against opportunistic or targeted attacks.
Grey Box
Here, the auditor has limited access or only partial information about the system, much like a colleague, partner, or user with restricted rights. This approach combines internal and external elements, allowing security to be tested at different access levels. It is particularly relevant for identifying vulnerabilities that could be exploited by individuals with some system knowledge, while still maintaining a degree of uncertainty.
White Box
The auditor has complete visibility into the system, including technical documentation, configuration, source code, and security policies. This approach allows for in-depth analysis, ideal for detecting as many vulnerabilities as possible, including those that would not be visible during an external attack. White-box penetration testing is often preferred for critical systems or during highly detailed security audits because it provides a comprehensive view of potential vulnerabilities.
Each penetration testing approach offers a different perspective on system security, depending on the level of access and information available to the simulated attacker. The choice between black box, gray box, and white box testing should be made based on security objectives, the organization's context, and the types of threats to be anticipated.
It is therefore essential to adapt the penetration testing approach to the criticality of the assets to be protected, the system's exposure surface, and the organization's business objectives. A well-targeted security assessment makes it possible to detect the most relevant weaknesses, anticipate the risks of compromise, and prioritize corrective actions. By choosing the most appropriate method, companies strengthen their cybersecurity posture and effectively protect themselves against increasingly sophisticated cybercriminal attacks.

Frequently Asked Questions about Pentesting
A pentest (computer penetration test) involves simulating a real attack against a company's information system, applications, or infrastructure to detect security vulnerabilities and measure resilience to cyber threats.
Penetration testing helps identify vulnerabilities before they are exploited, protect sensitive data, comply with standards (GDPR, ISO 27001, PCI-DSS…), and reassure customers and partners about the security of your systems.
Intrinsec stands out for its official ANSSI qualifications covering all critical areas (PASSI, PRIS, PACS), its recognized expertise and the fact that it conducted one of the very first pentests in France as early as 1995.
Testing can be external (from the internet), internal (from the company network), web-based (online applications), network-based, or social engineering-oriented. These approaches cover all potential attack vectors.
No, the intervention is planned and controlled to avoid any disruption to production. The techniques used are non-destructive and respect data confidentiality.
You will receive a detailed report outlining the identified vulnerabilities, technical recommendations, and a prioritized remediation plan to strengthen your information system security and ensure optimal compliance.
It is advisable to carry out a penetration test every year, or with each major change to your applications or infrastructure, to ensure an appropriate level of security against current threats.
