What is Zero Trust Network Access (ZTNA)? As working remotely has become more and more prevalent, it has become increasingly challenging to protect network resources since trust can no longer be granted based on location. Zero Trust Network Access (ZTNA) is the technology behind establishing a zero-trust model that ensures secure remote access regardless of where the user or application resides. ZTNA, also known as the software designed perimeter (SDP), operates on a model where trust is never implicit. It manages access authorizations at the application level and not at the network access level (as does the virtual private network or VPN). Although VPNs have been the de facto method of accessing corporate networks up until now, their limitations have created significant drawbacks for complex ecosystems.
ZTNA (Zero Trust Network Access) focuses on understanding who and what is accessing the network. It is often discussed as an alternative to using a traditional VPN (virtual private network). While VPNs have been a mainstay for decades, organizations are now shifting toward ZTNA to meet their plans and objectives. Here’s a quick look at some of the differences between VPNs and ZTNA:
To support the remote workforce, many companies are using VPNs (virtual private networks). However, ZTNA (Zero Trust Network Access) can be a wiser choice because, among many other limitations, VPNs lack integrated security and scalability options.
The benefits of implementing ZTNA include:
SASE, or Secure Access Service Edge, combines multiple network and security technologies into a single solution. Zero-trust defines how authentication should be performed but does not define a specific implementation like SASE does. SASE focuses less on the details of security than on the deployment model, while still following zero-trust principles. Rather than SASE being a set of standards to follow, it is more of a philosophical approach. While SASE is an identity-centric secure access platform, it utilizes zero-trust capabilities and supports the implementation of a zero-trust model to ensure secured access among applications, services, endpoints, and distributed users.
Although ZTNA (Zero Trust Network Access) is just a small part of SASE (Secure Access Service Edge), when enterprises leverage the SASE architecture, they receive the benefits of ZTNA, as well as a full suite of network security solutions that is not only highly scalable but also simple to manage. When combined with SASE, ZTNA is more granular, more secure, faster, and more reliable. When properly executed, SASE makes businesses more agile in a constantly changing world.
It is clear that ZTNA is the next evolution of VPN (virtual private network). With so many people accessing critical resources and applications from outside the network perimeter, it is obvious why security experts are shifting away from the paradigm of an open network built around inherent trust and moving toward a zero-trust model. The authentication method that ZTNA technology uses is both superior for users and more powerful for security teams. As businesses look to keep today’s highly complex networks secure, ZTNA seems like more and more of a reliable and promising alternative.
