Holistically, Zero Belief is usually described as a method or a framework, not a product offered by particular distributors. That is true; Zero Belief is a brand new manner of safety pondering that permeates a number of areas, not simply structure or know-how. Nonetheless, there are sensible implementations from distributors, like Zscaler, which have constructed their options round Zero Belief. As soon as deployed, this know-how offers safe entry for customers, issues, and workloads to public or non-public locations based mostly on Zero Belief rules.
When contemplating options based mostly on a Zero Belief structure, it’s important to grasp how this market is described and categorized. The most typical taxonomy known as Safety Service Edge or SSE (outlined by Gartner), an umbrella description for options providing Zero Belief structure, amongst different features.
Gartner’s SSE offers a framework that mixes the primary components of community safety–together with the Safe Internet Gateway (SWG), Zero Belief Community Entry (ZTNA), a Cloud Entry Safety Dealer (CASB), and firewall as a service (FWaaS), amongst different parts–as supplied from the cloud at a location close to the top consumer. ZTNA, on this context, relates merely to user-to-private software entry. The primary level is that when hosted on-premises, the safety stack strikes to the cloud or the “safety edge.” This affords safety operations all the advantages of cloud-hosted options, together with simplified complexity, scalability, simpler upkeep, structure, and so on.
How do Zero Belief structure ideas relate to the broader ideas of SSE? They’re carefully intertwined. Consider SSE as a sensible implementation of zero belief structure and different ecosystem parts like id, EDR, or SIEM/SOAR.

Is Zero Belief a passing fad, or is it right here to remain?
Zero Belief, as delivered by an SSE vendor, has already enormously impacted a number of organizations. It proved particularly invaluable because the pandemic moved staff dwelling, expanded the community, taxed VPN assets, and opened new doorways to attackers. Organizations that transitioned to ZTA have been capable of ship staff dwelling seamlessly whereas avoiding the widespread bottlenecks and safety considerations that usually accompany such a large workforce shift. That being stated, many organizations are nonetheless in numerous phases of their transformation journey.
A Zscaler survey outcomes present that as we speak, greater than 90% of organizations migrating to the cloud have a Zero Belief safety technique in place or plan to within the subsequent 12 months. Respondents indicated that zero belief community entry (ZTNA) is their No. 1 precedence, based mostly on offering a safe hybrid work setting. They cite their staff’ inconsistent entry experiences for on-premises and cloud-based functions and information as a high purpose to implement a zero trust-based hybrid work infrastructure. As well as, 68% of IT leaders additionally admit that cloud migration requires a rethinking of conventional safety fashions.
In our survey, the explanations to maneuver to zero belief safety have been ranked by respondents on this order:
- Enhance detection of superior threats
- Enhance detection of internet software assaults
- Broaden safety to guard delicate information

Gartner publishes the Magic Quadrant and Crucial Capabilities analysis on the Safety Service Edge, and as of this writing, is engaged on the 2023 model. They made the next prediction about ZTA and SSE, highlighting motion towards a consolidated SSE method over level options:
“By 2025, 80% of organizations looking for to acquire SSE-related safety companies will buy a consolidated SSE answer, fairly than stand-alone cloud entry safety dealer, safe internet gateway, and ZTNA choices, up from 15% in 2021.”
The info exhibits that conventional community and safety architectures have to be outfitted to offer ample safety and connectivity for the quickly evolving hybrid office. Globally, IT and safety leaders have or are actively planning to interchange their legacy architectures with a Zero Belief answer based mostly on an SSE platform.
So, to reply the query, ZTNA is one part of a complete SSE framework. Zero Belief and SSE usually are not synonymous, however with out ZTNA any SSE is incomplete.
