CERT emergency hotline: +33 1 47 28 38 39
Incident response protects your information system and all your IT systems against cyberattacks and cybercrime. As soon as a security incident is detected, our CERT mobilizes a chain of action to assess the alert, measure the IT risk, isolate the impacted infrastructure, and preserve sensitive data to ensure your information security remains intact. This operational approach aims to maintain the required level of security for your connected services and networks. Our interventions combine risk analysis, security audits, and forensic investigation to identify vulnerabilities and the attack chain. We implement immediate security measures—containment, endpoint cleanup, authentication strengthening, password management, encryption, and cryptography—and then recommend long-term security solutions to secure the systems and the overall system. After the incident, we conduct a post-incident audit and provide an improvement plan (hardening, network security, IT security policy) to reduce the likelihood of recurrence. The goal: to restore your services securely, capitalize on operational feedback, and align the technical strategy with governance.

A poorly handled crisis always costs more than a well-managed incident.
Poor coordination among stakeholders leads to longer downtime and therefore greater business losses. The same is true for inappropriate actions on the information system or a lack of evidence that prevents an investigation enabling effective and informed decision-making.
