What is Zero Trust?
According to NIST, “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.“
From the beginning, Zero Trust was conceived in response to the rapid rise of mobile and remote workers, bring your own device (BYOD) policies, shadow IT, and the rapid rise of cloud services.
For today’s businesses, innovation continues to undergo deep digital transformation. Consequently, corporate networks, infrastructures, applications and data are moving quickly beyond traditional on-premises profiles to the cloud, edge, mobile devices, value-chain partners and others.
Organizations therefore must offer a flexible and agile work environment to their workforce, enabling employees to work anywhere they want while maintaining control over security at all times.
+30%
The trend towards the cloud is confirmed, with a market growth of more than 30% per year according to many analysts.

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 Zero Trust Architecture (ZTA)?
NIST defines Zero Trust Architecture (ZTA) as “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 Zero Trust Network Access (ZTNA)?
Zero Trust Network Access (ZTNA) 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 of an efficient evaluation of the overall situation and context of the user, the 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 continuously monitoring and assessing all access requests to protected information and assets.
Unified user experience
As cloud adoption and home working are gaining popularity, the Zero Trust approach will enable the roll-out of new ways of working.

Manage user identities
The identity lifecycle for your users evolves quickly, and their access needs are constantly changing. For more efficiency in their daily tasks, users should be quickly granted access to the required applications and information. However, you still need to ensure that only authorized people can access the right resources.
How do you strike a 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 allow your organization to manage the lifecycle of identities and access while satisfying the need for logical access, multi-factor authentication, identity federation and 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 card operating systems: Support secure functionalities such as system login, secure email, digital signatures and web authentication with smart cards
Gain more visibility and control over your data
Today, users are no longer limited to the perimeter of their organization. Working from anywhere and with any device, they use multiple cloud services and applications every day.
In this context, how can you be sure that your sensitive data — whether at rest or in motion — are compliant with the company’s security requirements?
- Data encryption: Ensure total protection for sensitive data with encryption on every medium (virtual machine, database, workstation, applications, etc.)
- Data governance services: Conduct data classification to identify where your data is stored and how the existing security is provisioned
- Cloud access security broker (CASB): Control and enforce data privacy and compliance policies across shadow IT and sanctioned cloud apps.
