Penetration Testing — Paris, France

Find your vulnerabilities before an attacker does.

Based in Paris, our team conducts penetration tests on your systems, applications and networks to reveal your vulnerabilities and deliver a clear, prioritised remediation plan.

Test types

From the internet

External penetration test

Conducted from our premises over a standard internet connection, this test assesses the resilience of your internet-facing infrastructure and services against an outside attacker. The objective is to determine whether a remote attacker can compromise your systems without prior access.

  • Web applications & API
  • Exposed network infrastructure
  • Cloud services
  • Authentication & remote access
From the local network

Internal penetration test

Conducted from the client's premises or via an implant deployed on their network, this test simulates an insider threat: malicious employee, phishing-compromised machine, maintenance agent or external consultant. The objective is to assess what an attacker with physical or network access can achieve.

  • Active Directory & internal network
  • Segmentation & lateral movement
  • Workstations & servers
  • Privilege escalation
