Cyber Crisis Management

A cyber crisis is not just a technical problem. It's a strategic, human, and organizational test for your company.

Cyber crisis management combines risk analysis, security audits, and operational procedures to limit the impact of security incidents on your IT systems and information security. We help identify vulnerabilities in your IT systems and connected devices, assess IT risk, and define priority security measures (encryption, cryptography, enhanced authentication, and password management) to ensure your sensitive data remains secure. When an attack or data breach occurs, our approach integrates real-time response (crisis team, forensics, threat hunting) with legal and communications coordination to contain cybercrime, protect reputation, and ensure business continuity. Containment actions are followed by post-incident audits and an IT security policy improvement plan to secure systems and strengthen network and overall system security. Beyond simply reacting, we focus on prevention: regular audits, simulation exercises, security policy reviews, and the implementation of security solutions to sustainably raise your organization's digital security level. Request a callback from an expert — Schedule a personalized crisis assessment to define immediate and strategic measures to protect the security of your infrastructure.

Your major challenges

Prepare your organization for critical cyber scenarios (ransomware, data breaches, IT system outages, etc.)

Mobilizing the right people, at the right time, with the right decisions

Knowing how to arbitrate between legal, technical, business, and media choices

Comply with legal requirements (CNIL/NIS2 notification, complaint, ANSSI coordination, etc.)

Avoid internal disorganization, loss of trust, and reputational damage.

A crisis cannot be improvised. Neither can your response.

An organization that has never tested its Business Continuity Plan/Disaster Recovery Plan or its crisis management team remains vulnerable. Prepare thoroughly to act quickly.
