Penetration testing by cybersecurity experts
A penetration test simulates a real-world attack on your infrastructure to identify weaknesses before a cybercriminal can exploit them. Cyberattacks evolve every day, making this type of validation essential. Deploying security tools is no longer enough — you need proof that your environment can truly withstand pressure. At Groupe SL, our cybersecurity experts reproduce concrete attack scenarios to give you a clear and actionable view of your vulnerabilities.
Why perform a penetration test?
A penetration test validates the strength of your technology environment under real-world conditions.
By performing one, you can:
- Identify critical vulnerabilities before an attacker finds them.
- Verify the security of your systems, networks, and applications.
- Prioritize security fixes based on their actual impact.
Each engagement is tailored to the size and complexity of your organization. You receive a clear report that your internal teams can act on. A valuable asset for audits and certifications
A well-executed penetration test directly supports your compliance efforts. It provides tangible proof of due diligence. Our technical reports are designed to be understood by both auditors and management.
Types of penetration tests offered
External penetration test
This test simulates an attack originating from the Internet. It assesses the security of your firewalls, servers, and publicly accessible applications. The goal is to identify potential entry points from outside your network.
Internal penetration test
It reproduces the scenario of a malicious employee, a compromised workstation, or unauthorized access within your environment. This type of test highlights vulnerabilities that are often invisible to external audits.
Our proven methodology
Each test follows a rigorous methodology and complies with industry standards:
- Planning: defining the scope, objectives, and rules of engagement.
- Reconnaissance: gathering information about your systems, addresses, and infrastructure.
- Exploitation: simulating real attacks, with or without privileges.
