Introduction to Universal Zero Trust Network Access (UZTNA)

Universal Zero Trust Network Access (UZTNA) is a cutting-edge security framework that consistently applies zero-trust principles to all environments, whether users are on-premises, remote, or hybrid. It centralizes user or device access policies, allowing a single policy definition.

As you know already that Zero Trust Network Access (ZTNA) authenticates users and gives access to particular apps based on identification and context policies, thereby limiting attack surfaces and restricting network movement.

Future towards Universal ZTNA

Universal ZTNA eliminates the need for legacy remote access gear such as VPNs, allowing enterprises to rely entirely on software-based access control solutions.
Universal ZTNA provides seamless user experiences because user traffic is not backhauled through the data center. Instead, users have quick, direct access to their preferred program.
Consistent security: Universal ZTNA ensures that employees are subject to the same zero-trust security policies whether they work in or out of the office.
Scalability is effortless with a cloud Universal ZTNA service. An organization just leverages additional licenses.
Universal ZTNA can be installed from anywhere in a matter of days, as opposed to alternative systems, which might take weeks or months.

ZTNA or Universal ZTNA .. Where to go ?

Many solutions currently claim to provide "zero trust network access," but this usually translates into a demanding, on-premises network security implementation with historical network micro-segmentation. While this technology may be able to protect in-office users with a few loosely linked zero trust network access rules, a real universal ZTNA solution is more like a security fabric, providing zero trust protection to all users regardless of where they work.

This can be explained by the fact that a universal ZTNA solution is created in the cloud, usually using a security service edge (SSE) or secure access service edge (SASE) framework. Regardless of where they work—at an office, at home, in a coffee shop, or anyplace else with an internet connection—users are given access on the least privilege principle with Universal ZTNA.

An on-premises, non-universal architecture just cannot provide secure connectivity to networks, SaaS, and apps from anywhere. Furthermore, a solution isn't truly a zero trust solution and it's definitely not a universal ZTNA solution if it says it can provide zero trust security using on-premises hardware like firewalls. This is due to the fact that a lot of these outdated systems will only provide access based on authentication, not on location, device posture, or context.

No matter where users work from, a universal ZTNA provides safe network, SaaS, and application access without requiring implicit trust. This special capacity stems from a cloud-native ZTNA.

Future of VPN in case Universal ZTNA approaching ?

By enabling end users to safely access a network and, consequently, corporate resources via a dedicated tunnel, typically via single sign-on (SSO), virtual private networks (VPNs) are intended to streamline access control.

For users who wanted to operate remotely for a day or two, VPNs performed admirably. However, a lack of scalability combined with expensive prices and maintenance requirements rendered VPNs inefficient as the world saw an increase in long-term remote workers, which ultimately led to work-from-anywhere policies. Furthermore, as public cloud use accelerated, it became increasingly challenging to implement security controls for these remote workers, which negatively impacted user experience.

However, the attack surface that VPNs provide is their primary issue. All of the network, endpoints, and data that the VPN was designed to safeguard are accessible to any person or entity with the proper SSO credentials so they can move laterally within the network.

Using the least privilege concept, Universal ZTNA protects user access. Zero trust only enables authentication when the user, identity, device, and location are all in agreement, as opposed to relying on accurate credentials.

Moreover, granular access to resources, as opposed to network access, is offered by universal ZTNA. Malicious users cannot move laterally since users are securely and directly connected to the apps and data they want. Additionally, using a UZTNA architecture greatly enhances user experiences because user connections are direct.
