Offensive security

Go from presumed to be safe to proven safe.

We put your security to the test with realistic penetration tests to reveal your critical flaws. Our unique ability to test and fix with the same teams turns each vulnerability into concrete remediations — strengthening your resilience and compliance.

Your main challenges

Presumed trust that masks critical vulnerabilities.

Many organizations equate the absence of an incident with controlled security. Without a clear map of their exhibition area, they maintain an illusion of protection. When an attack occurs, compromise often occurs before detection, with immediate impacts on business and reputation.

Security devices that reassure more than they protect.

Tools, audits, procedures: devices are multiplying without certainty about their effectiveness. Until they are tested under real attack conditions, teams don't know if their defenses hold up, leaving a dangerous gap between perception and reality.

Increasing demands that organizations are struggling to demonstrate.

Regulators, insurers, and major customers now require clear evidence of an organization's true security level. Without tangible evidence to demonstrate their level of protection, businesses may not be able to demonstrate compliance — and see their credibility weakened with their partners.

Our approach

Put your security to the test as a determined attacker would

We put your systems to the test via a gradual combination of external and internal approaches (black/grey/white box). This immersion allows us to detect truly exploitable vulnerabilities, under the same conditions as a determined attacker.

Prioritize risks based on their real business impact

Each vulnerability is analyzed in your context: probability of exploitation, consequences on your key applications, data exposure, business continuity. You get a clear picture of what's really threatening your organization — and therefore what to deal with first.

Co-build realistic remediations with your teams

Instead of producing a final report that is difficult to use, we work daily with your teams to explain each vulnerability and build realistic corrections.

Transforming every mission into sustainable progress

Thanks to our dual expertise in offensive and software engineering, we capitalize on the lessons of the mission to strengthen your development cycles: correction models, reusable best practices, sustainable technical improvements. You thus gain autonomy and maturity.
