At a time when cyberthreats are proliferating and the traditional boundaries of IT systems are breaking down, the Zero Trust model is emerging as a necessity for businesses. But is this truly a strategic shift, or just a passing trend? We take a closer look.

A trend that is taking root in organizations for the long term

With 30% of organizations already implementing a Zero Trust strategy by 2024, and 27% in the process of deploying one (source: Statista), the trend is clear: this model is becoming the standard. It is neither a buzzword nor a technological utopia. It is a driver of secure digital transformation,aligned with regulatory requirements (GDPR, NIS2, ISO 27001) and business imperatives. In other words, Zero Trust goes beyond a simple concept to establish itself as a strategic framework capable of providing organizations with long-term support in an increasingly exposed digital environment.

Zero Trust is based more on substance than on form

As IT infrastructures evolve, traditional security approaches are reaching their limits. Targeted attacks, lateral movement, and the compromise of internal credentials can no longer be contained by perimeter defense alone. In this context, many companies are shifting their strategy toward a more granular, adaptive security model based on systematic access verification. The Zero Trust model fits into this framework , designed to provide concrete solutions to today’s challenges: strengthening resilience, limiting attack surfaces, and ensuring a high level of security, even in hybrid or distributed environments.

The Three Pillars of the Zero Trust Model

Zero Trust is based on a simple yet radical principle: never assume trust; always verify. Every access attempt is treated as a potential threat.

  • Explicit verification
    Each access attempt is evaluated based on multiple dynamic criteria: user identity, device status, geographic location, typical behavior, etc. NIST, in its reference publication SP 800-207, recommends systematic and adaptive authentication for all interactions with critical resources.

  • Principle of Least Privilege
    Access to systems and data must be strictly limited to what is necessary, in accordance with the Just-In-Time (JIT) and Just-Enough-Access (JEA) approaches. This measure reduces the potential impact of a compromise by limiting the privileges granted to users and services.

  • Assumption of Compromise
    The Zero Trust model is based on the idea that any infrastructure can be—or will eventually be—compromised. It therefore relies on continuous monitoring, behavioral detection, and microsegmentation to contain the lateral movement of a potential attacker.

A standard promoted by cybersecurity authorities

The Zero Trust model now has the official backing of major cybersecurity agencies. The NIST in the United States designates it as a reference architecture in its SP 800-207 guide. In France, theANSSI explicitly recommends its adoption in several of its practical guides intended for operators of critical infrastructure (OIV) and public entities. This institutional consensus confirms thatZero Trust is not merely a theoretical concept, but a robust operational framework.

A shift in approach rather than a technical transformation

Adopting a Zero Trust approach is more than just a technological transformation: it is a governance and risk management strategy focused on visibility, control, and continuous verification of access. In a landscape where cyberattacks are becoming more frequent, faster, and more costly, never trusting by default becomes much more than a precautionary measure— it is a strategic imperative.
