Zero Trust Security: what does it consist of?
What does Zero Trust mean?
Zero Trust is a security framework based on the principle “never trust, always verify.”
According to this principle, access to corporate resources is strictly controlled and granted only after thorough verification of the identity and context of the user or device, applying security rules based on the principle of least privilege.
This modern approach continuously validates security configurations and postures to ensure strong protection against rapidly evolving threats.
In recent years, the Zero Trust framework has become the foundational paradigm for securing digital infrastructures.
By 2026, Gartner estimates that approximately 10% of large enterprises will adopt a mature program based on this security approach.
Why the Zero Trust model emerged
Historically, cybersecurity relied on a perimeter-based approach (the so-called castle-and-moat model): everything inside the corporate network was considered trustworthy. Today, this paradigm is no longer sustainable.
Cloud computing, SaaS applications, remote access, mobile devices, and OT environments have dissolved the traditional perimeter. Modern threats also exploit compromised credentials and lateral movement, making implicit trust ineffective.
The Zero Trust model was created precisely to address these new challenges, eliminating the concept of default trust and introducing continuous, context-aware controls.
How to build a Zero Trust architecture
To implement a Zero Trust architecture, it is essential to follow several key steps:
- Identification and authentication: every user and device must be accurately identified. Using multi-factor authentication (MFA) is a fundamental practice to enhance security.
- Network segmentation: dividing the network into micro-segments isolates resources and limits lateral movement in case of a breach.
- Continuous monitoring: real-time activity monitoring helps detect abnormal behaviors and potential threats, enabling timely responses.
- Granular access policies: defining who can access what, under which conditions, and for how long allows for more precise and dynamic controls.
When integrated into a unified framework, these measures create a secure and resilient environment capable of meeting the challenges of Zero Trust cybersecurity.
The fundamental principles of the Zero Trust model
A proper implementation of the Zero Trust model is based on several key principles that ensure strong enterprise security:
Continuous verification: every user, device, or application must be verified each time it connects to the network, regardless of previous access.
Least-privilege access: each user or system is granted only the minimum privileges necessary to perform their specific tasks.
Micro-segmentation: the network is divided into small, isolated segments to contain and limit the spread of a threat.
Identity-based security: identity becomes the new security perimeter.
Visibility and continuous monitoring: constant collection and analysis of logs and security events.
What are the benefits of the Zero Trust approach?
Adopting the Zero Trust strategy offers numerous advantages:
- Reduced risk of breaches: rigorous controls and constant verifications limit unauthorized access and contain potential threats.
- Greater visibility and control: continuous monitoring systems provide companies with a detailed view of data flows and activities within the network.
- Flexibility and scalability: the Zero Trust architecture easily adapts to dynamic networks and cloud environments, simplifying security management in complex scenarios.
- Protection of critical assets: network segmentation and granular access policies ensure that the most sensitive resources are always protected, reducing the impact of potential attacks.
Zero Trust and Regulatory Compliance
The Zero Trust model provides concrete support for compliance with regulations and security frameworks such as:
NIS2, by improving access control, logging, and incident management.
GDPR, by strengthening the protection of personal data.
NIST standards, ISO/IEC 27001, and international best practices.
Event traceability and centralized policy management make audits and compliance activities easier.
