Its main mission is to develop and implement a security policy that protects corporate data, systems, and infrastructures.

The CISO works to implement appropriate security protocols and tools, such as data encryption, firewalls, access management, and network monitoring to detect suspicious activity. In the event of a cyber attack or incident, he coordinates response actions, conducts investigations and puts in place measures to avoid future incidents.

Another of its responsibilities is to raise awareness and train employees on good security practices, especially in terms of password management and phishing. The CISO is also the guarantor of the company's compliance with current regulations, such as the GDPR, and ensures the proper application of security standards.

In addition to its protection and prevention functions, the CISO is a key interlocutor for management and other departments of the company. It informs them of security risks and the actions needed to reduce them, while ensuring that the solutions implemented integrate well with the goals and needs of the organization.

In summary, the CISO plays a central role in defending the business against cyber threats. It develops strategies, trains teams, and reacts to incidents to ensure the security of information and systems.
