Réalisation d'un audit technique de sécurité

Technical security audit

Check the quality of your IT security strategy

Our technical and organizational security audits follow a proven methodology to best fit your IS.

We adopt a complete approach consisting in first defining the evaluation criteria and listing the existing, such as your IT assets, the mapping of your IS, your processes… Then we audit your servers, networks, firewalls, security protocols. Finally, we recommend corrective actions and propose an action plan.

After the audit, our teams can also intervene on the remediation of all or part of the identified vulnerabilities. To evaluate the results of the actions taken, we then perform a second audit and establish new recommendations.

Application pentest

Test your IS with a penetration test

Simulate a cyber attack with a black box, white box or grey box penetration test on your web application and find the vulnerabilities in your IT system.

Our Pentest allows you to test your current IT security protocols, to identify intrusion risks, vulnerabilities, to prevent them and optimize the reactivity in case of crisis, to prove the compliance of the infrastructure with regulations. In addition to being a security monitoring tool, our pentests also make excellent customer reassurance proofs.
