Zero Trust: the new security standard for remote working

While this change offers benefits in terms of productivity and flexibility, it has also multiplied cybersecurity risks: access from unsecured networks, use of personal devices, and increasingly sophisticated attacks.

This is the context in which the Zero Trust model has emerged, considered the new security standard for protecting distributed digital environments.

What is Zero Trust?

The Zero Trust principle breaks with the traditional paradigm of “trust everything inside the corporate network.” Instead, it establishes a clear rule: “Never trust, always verify.”

This means that every access, user, device, or application must be authenticated, authorized, and continuously validated before permissions are granted.

According to Forrester Research (2024), organizations that adopt Zero Trust reduce the likelihood of security breaches by 42% compared to those that rely on traditional perimeter models.

Key principles of the Zero Trust model

1. Multi-factor authentication (MFA): each access requires additional validation (password + token + biometrics).

2. Least privilege access: users are granted only the permissions they strictly need.

3. Network segmentation: resources are divided to prevent an attacker from moving laterally.

4. Continuous monitoring: constant analysis of traffic and user/device behavior.

5. End-to-end encryption: protection of data both in transit and at rest.

Zero Trust and remote work

Remote work exposes organizations to multiple vulnerabilities. According to IBM's Cost of a Data Breach Report (2024), the average cost of a data breach is $4.45 million, which is 15% higher in cases where remote work was involved.

Implementing Zero Trust offers concrete benefits in this scenario:

• Remote access protection: the device is validated as secure before accessing critical systems.

• Cloud security: ideal for companies that have migrated to solutions such as SAP in the cloud, Azure, or AWS, where access comes from multiple locations.

• BYOD (Bring Your Own Device): allows you to control and monitor personal devices used to connect to the corporate network.

• Faster response: Zero Trust systems integrate artificial intelligence to detect and block suspicious behavior in real time.

A Microsoft report (2024) highlights that companies that adopt Zero Trust have reduced the impact of ransomware incidents by 50%.

Strategic benefits for companies

Adopting Zero Trust is not only a technical decision, but also a strategic one:

• Greater trust with customers and partners: compliance with security standards becomes a competitive advantage.

• Regulatory compliance: Zero Trust makes it easier to comply with regulations such as GDPR, HIPAA, or FIPS 140-3, which require advanced data protection.

• Scalability: Easily adapts to hybrid and fast-growing business models.

• Long-term cost reduction: Although the initial investment can be significant, the savings from avoiding breaches and fines are substantial.

Zero Trust use cases in action

1. Financial sector: protection of online transactions and secure access for remote employees to critical systems.

2. Manufacturing 4.0: access validation in factories connected with IoT devices.

3. Digital health: secure access to medical records and patient data, reducing the risk of leaks.

4. Tech SMEs: securing cloud environments with scalable controls and low initial costs.

According to IDC (2025), 90% of medium-sized companies in Latin America plan to implement Zero Trust models in the next 3 years.

Remote working will continue to be a dominant model in the near future, but with it also come growing cybersecurity risks. The Zero Trust model is positioned as the best response to ensure that every user, device, and connection is validated, reducing vulnerabilities and increasing business resilience.
