SAFER APPROACH TO
REMOTE NETWORK ACCESS

With users logging in from different locations, multiple devices and using various cloud services and apps, it’s never been more vital to manage your network security. That means taking control of who’s allowed on your network, what they have access to, and how they’re allowed to use it.

Bring Your Own Device (BYOD) policies make ZTNA solutions essential for any enterprise cloud environment with unmanaged devices. With a zero-trust approach to authentication and cybersecurity, you can prevent unauthorized intrusion and keep corporate data out of harm’s way

The Benefits of GTT ZTNA

GTT provides security services that transcend other cloud security options. Control application access to protect your cloud-based data centers and maintain a high-level security posture.

Granular Access Control

Implement Zero Trust Network Access to leverage identity-specific policies and determine access privileges at the individual and application levels. Prevent malware and other threats to your remote workers, end users and bottom line.

Simplified Workflow

Reduce network segmentation and complexity with a single approach to policy management and threat detection. With ZTNA, you don’t have to rely on multiple VPNs, VDIs, and internal firewalls. As a component of SASE, ZTNA provides a simplified experience.

Consistent UX

Provide a reliable, high-performance user experience (UX) by permitting access to the network for authorized end users regardless of their location. This permission is vital to ensuring your remote workforce and end users have secure connectivity for core business operations.

CLOUD-DELIVERED ZTNA

ZTNA strengthens remote access through an explicit trust framework. By verifying every user’s identity before permitting access to the network, ZTNA automatically dictates which approved resources that user can access. As part of a multi-cloud-delivered package, ZTNA scales across all network edges without additional cost or complexity—all while providing the benefits of a multi-point security solution.

SECURE REMOTE ACCESS VS ZERO TRUST NETWORK ACCESS

Virtual private networks establish a private and encrypted connection between remote users and the corporate network. However, VPNs are an appliance-based method, meaning they’re difficult to scale for mobile workforces and take a very broad approach to security, control and visibility. By offering implicit trust, VPNs allow users access to the network without verifying their identity, enabling them to access and use data at their discretion.

Zero Trust Network Access, on the other hand, is a part of the Secure Access Service Edge (SASE) security model that also includes FWaaSCASBSWG and managed SD-WAN, in a cloud-native environment. ZTNA is built on the public internet and isolates providing specific application access from giving network access to user devices. ZTNA also runs on a software-defined perimeter (SDP), which relies on the “dark cloud.” Access policies can be controlled for cloud applications separate from network permissions.

No, ZTNA applies to both remote and on-premise access; it ensures all access requests are treated with the same level of scrutiny, regardless of location.

When properly implemented, ZTNA can enhance the user experience by allowing secure access from anywhere.
Yes, ZNTA’s principle of “least privilege access” helps limit the potential damage caused by insiders and external attackers by restricting access to only what is necessary for a user’s role.
