For years, corporate cybersecurity has focused on protecting the perimeter, assuming that users and devices inside the network were trustworthy.<\/h2><\/div><\/div>[vc_column_text css=””]Today, with the rise of remote working, cloud services, mobile devices, and the increasing sophistication of cyberattacks, the security landscape has changed completely.<\/p>\n

In distributed environments, where data, applications and users are outside the traditional perimeter, automatic trust becomes a risk. This is why the Zero Trust model has emerged: a strategy designed to protect modern infrastructure where implicit trust is no longer enough.<\/strong>
\nAt Idea TSG, we believe that adopting this approach is not merely a technical upgrade, but a necessary evolution to ensure the digital resilience of organisations.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_custom_heading text=”What is the Zero Trust model?” font_container=”tag:h2|font_size:24|text_align:left|color:%23F6303E” google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_separator color=”custom” style=”dotted” border_width=”2″ accent_color=”#cccccc”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]The Zero Trust model is a cybersecurity<\/strong> approach built on a clear premise: do not automatically trust any user, device or system,<\/strong> regardless of whether they are inside or outside the corporate network.<\/p>\n

Unlike traditional models based on security perimeters, Zero Trust demands that every access attempt is verified. In other words<\/strong>, every access request must be authenticated, authorised, and evaluated before allowing any interaction with company systems, applications, or data. <\/p>\n

Threats can originate from both outside and inside the organisation. As a result, under this model, security no longer focuses solely on the network, but shifts to focusing on the identity, context, and behaviour of users and devices.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]

<\/div>[vc_custom_heading text=”The 3 pillars of Zero Trust: verify explicitly, least privilege, and assume breach” font_container=”tag:h2|font_size:24|text_align:left|color:%23f6303e” google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_separator color=”custom” style=”dotted” border_width=”2″ accent_color=”#cccccc”][vc_column_text css=””]<\/p>\n

The Zero Trust approach is based on these three key principles:<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_custom_heading text=”Verify explicitly” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_column_text css=””]Every access request must be validated taking into account various contextual factors, such as user identity, device status, location, time of access, or usual behaviour.
\nContinuous verification makes it possible to detect anomalies and block suspicious access before it can turn into a security incident.[\/vc_column_text][vc_custom_heading text=”Least privilege” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_column_text css=””]The principle of least privilege consists of providing each user with only the permissions necessary to perform their work. In this way, the potential impact of a compromised account is limited, preventing attackers from moving freely across the infrastructure.[\/vc_column_text][vc_custom_heading text=”Assume breach” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][\/vc_column][vc_column width=”1\/2″]

Consequently, security architectures must be designed to rapidly detect any suspicious activity and contain it before it causes significant damage.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]

Cybercriminals frequently gain access using stolen credentials or malicious links designed to deceive users.
To mitigate this risk, the Zero Trust model enforces continuous verification and restricts access permissions. Even if an attacker manages to compromise an account, least privilege restrictions and additional security controls make it significantly harder for them to access critical systems or move laterally across the network.[\/vc_column_text][vc_custom_heading text=”Security for hybrid and multi-cloud environments” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_column_text css=””]Digital transformation<\/a> has led many organisations to deploy hybrid and multi-cloud environments, managing applications and data across their own data centres and cloud platforms.
\nIn these environments\u2014where the traditional security perimeter disappears\u2014Zero Trust provides a framework tailored to this reality<\/strong>, safeguarding access to resources regardless of where they are located. This approach centres security on identity and the context of each access request, making it possible to protect complex, distributed infrastructures.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_custom_heading text=”Compliance, GDPR and cybersecurity regulations” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_column_text css=””]An increasing number of regulations require organisations to implement advanced data protection and access control measures. Regulations such as GDPR or various cybersecurity frameworks demand clear evidence of control over who accesses information and how it is managed.
Adopting a Zero Trust architecture facilitates compliance with these requirements, as it incorporates mechanisms such as robust authentication, access logging, and continuous monitoring\u2014enhancing security while simplifying auditing and regulatory compliance processes.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″]

In addition to a password, the user is prompted for a temporary code, a physical device, or even biometric recognition. This combination of factors significantly reduces the risk of unauthorised access, even in cases where credentials have been compromised.[\/vc_column_text][vc_custom_heading text=”Network microsegmentation” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text css=””]Microsegmentation involves dividing the network into smaller, controlled segments. This way, if an attacker manages to gain access to one part of the system, they will not be able to easily move to other critical areas. In addition to limiting lateral movement within the infrastructure, this strategy also facilitates detailed control of traffic between different services and applications.[\/vc_column_text][vc_custom_heading text=”IAM (Identity and Access Management) and endpoint security” font_container=”tag:h3|font_size:20px|text_align:left|color:%235C5858″ google_fonts=”font_family:Montserrat%3Aregular%2C700|font_style:700%20bold%20regular%3A700%3Anormal” css=””][vc_column_text css=””]Identity and Access Management, known as IAM, is a system that allows you to manage who can access which resources and under what conditions, ensuring that each user has the appropriate permissions.
Furthermore, protecting endpoints (computers, smartphones or tablets) is essential, as they are the gateway to corporate systems. Keeping them updated, monitoring their status and ensuring they comply with security policies helps prevent compromised devices from being used to access the network.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″]
