In a context marked by accelerated digital transformation and the continuous growth in the number and sophistication of cyberthreats, the "Trust but verify" model of cybersecurity is becoming increasingly remote from good practices in information security management.

The explosive growth of incidents with impacting consequences on the operations of sectors that are essential to the continued development of socio-economic activities, ranging from Ransomware to Databreachs, most of which are initiated by compromising credentials using social engineering techniques, has reinforced the need to combat these threats through new cybersecurity approaches. Zero Trust has emerged to respond to these challenges, representing a fundamental change in the cybersecurity paradigm.

Zero Trust represents a radical departure from the conventional security model, based on apparently simple but profoundly impactful principles, adopting the "Never trust, always verify" model. Instead of starting from the traditional view that everything inside the company's network is reliable, this model assumes that everything inside our "castle" is already or will be compromised.

• Verify: all users, devices or systems attempting to access resources must be authenticated and authorized.
• Limit the "impact radius": minimum access required to complete tasks, reducing the risk of unauthorized access and impact.  
• Monitor continuously: Continuous monitoring and analysis of network traffic, user behavior and system activity to detect and respond to potential threats in real time.
• Adapt and respond: Collect behavioral and contextual data from the entire technological environment in order to be able to respond quickly and incisively.
