On the road to Zero Trust

The evolution of cybersecurity to Zero Trust

What is Zero Trust ?

Zero Trust provides a collection of concepts and ideas designed to minimize uncertainty in enforcing accurate, least privilege per-request access decisions in information systems and services in the face of a network viewed as compromised”. (NIST definition)

Zero Trust was conceived at the beginning in response to the rapid rise of mobile and remote workers, the bring your own devices (BYOD), the shadow IT, and the rapid rise of cloud services.

Today’s businesses innovation continues to undergo deep digital transformation. Consequently, corporate networks, infrastructures, applications and data are moving quickly beyond traditional on-premise profiles (e.g. to the cloud, Edge, mobile devices, value-chain partners, etc.).

Organizations therefore needs to additionally offer a flexible and agile work environment to their workforce, enabling employees to work from anywhere they want, at any timemaintaining control over its security.

Zero Trust is a philosophy, not a product!


Zero Trust is a cybersecurity paradigm focused on resource protection (e.g. services and data) and the premise that trust is never granted
implicitly but must be continually evaluated.

Atos cybersecurity solutions provide secure collaborative environments while maintaining a consistent user experience and satisfaction.

What is ZTA, Zero Trust Architecture?

Zero Trust Architecture (ZTA) is an enterprise’s cybersecurity plan that utilizes Zero Trust concepts and encompasses component relationships, workflow planning, and access policies. Therefore, a Zero Trust enterprise is the network infrastructure (physical and virtual) and operational policies that are in place for an enterprise as a product of a Zero Trust architecture plan”.

What is ZTNA, Zero Trust Network Access?

Zero Trust Network Access (ZTNA), which is the application of Zero Trust concept and ideas to the network access to applications and their data, accepts that users, applications, and data will not reside on a common trusted network. The approach consists in an efficient evaluation of the overall situation and context of the user, his device, the requested resource and the overall enterprise security risk posture.

Benefits of Zero Trust

Increased data access visibility

The Zero Trust approach increases the visibility of how data is being accessed by users, workloads, and devices.

Reduced attack surface

The Zero Trust approach can reduce the attack surface of system breaches by continuous monitoring and assessing all the access requests to the protected information and assets.

User work

Unified user experience

As the cloud adoption and home working are gaining popularity, the Zero Trust approach will enable the roll out of new ways of working.

Atos cybersecurity Digital Workplace Security

Manage your users’ IDENTITIES

The identity’s lifecycle of your users follows the same pace and their access needs constantly change. For more efficiency in their daily tasks, users should be granted access to the required applications and information quickly. However, you still need to ensure only authorized people can access the right resources.

How to keep the balance between security and efficiency?
>> Trusted digital identities (PKI): Provide a personal and trusted identity to your users (solution available as an appliance >> )
>> Identity Governance and Administration: Manage digital user identities across multiple sites and streamline your access policies (also available as a Service >>).

Secure and simplify ACCESS from anywhere

Discover solutions that allows organization to manage the lifecycle of identities and access while covering needs for logical access, multifactor authentication, federation of identities, universal Single Sign-On (SSO).

To ensure users are well protected without hampering their daily activities, flexible security solutions should be implemented.
>> Web Access Management: Protect your system from any unauthorized remote access with adaptive multi-factor authentication
>> Enterprise Single Sign-On: Replace user passwords with a single authentication without compromising security policies
>> Smart cards operating systems: Support secure functionalities such as system login, secure email, digital signatures and web authentication with smart cards.

Gain more visibility and control on your DATA

Today, users are no longer limited to the perimeter of their organization. Working from anywhere and with any device, they are using several cloud services and applications everyday.

In this context, how to be sure that your sensitive data -at rest, in use or in motion- are compliant with the company’s security requirements?
>> Data encryption: Ensure a total sensitive data protection, at rest and in motion, with encryption on every support (virtual machine, database, workstation, applications…)
>> Data governance services: Conduct data classification to identify where your data is stored and how the existing security is provisioned
>> Cloud Security Access Broker (CASB): Control and enforce data privacy and compliance policies across Shadow IT and sanctioned Cloud apps.
