Zero Trust vs. SASE: Which one is more suitable to your business?


Zero Trust and SASE (Security Access Service Edge) have become the most significant concern of organizations because of sudden changes in the business crafts over the past few years. Business models have changed on the spur of the moment to fit in with a remote workforce. It brought along increased threats to the software environment of a network.

To avoid such threats, organizations adopt a zero-trust approach and a more flexible and secure security posture, SASE. But the question is Zero Trust vs. SASE, which is better for your business? This question is top of mind for almost every organization. 

If you are also confused between the two, then here is your guide. This article contains everything you need to know about Zero Trust vs. SASE and which one is more suitable for your business.

What is Zero Trust?

Zero Trust is a security framework that assumes everyone on the network, whether a device or a human being, is a potential attacker. Zero Trust uses a security scheme to base its presumption regarding the security of any network that is always at risk to external and internal threats. This security model strategizes a thorough approach to counter such threats. 

What is SASE?

Secure Access Service Edge has emerged as a proactive security approach to quickly expanding cloud traffic. It provides consistent security against constantly emerging cloud-native threats. This security framework is a whole package that works along with SD-WAN capabilities combined with other network security functions, including;

  • CASB (Cloud Access Security Broker)
  • SWG (Secure Web Gateway)
  • ZTAN (Zero Trust Access Network)

With the rise of SASE, there has been an increase in the importance of Remote Access VPNs. As traditional technology lacks integration with SASE, Remote Access VPNs secure private cloud resources of a network more proficiently. There is no need to struggle and find the perfect Remote Access VPN solutions for your business.

Zero Trust vs. SASE 

Zero Trust is a business scheme to circumvent security threats to the network, whereas SASE provides management for entrepreneurs to design robust security solutions for the future. 

While SASE details a solution to provide secure access at the edge. Other Zero Trust requirements on effective monitoring of security risks to the business, continuous supervision of the software environment, and aligning solutions to observation requirements go beyond any single technical solution.  

You should consider Zero Trust as a strategy that eliminates security threats. In contrast, SASE is a solution that enables a network to proactively devise specific technologies to protect a network’s software system.

Zero Trust eliminates security risks against all entities, whether a device or a human being, based upon a no-trust approach. In contrast, SASE is a framework that can combine all possible technologies into a single cloud-based service, ensuring a robust security posture.

Developers based Zero Trust upon the principles of least privileged access. So, every identity gets authenticated again, even if proven before. Every transaction has to be verified again. On the other hand, SASE is the infrastructure that focuses on how businesses deploy networking or security services. SASE involves

  • network and network security services,
  • identity, and
  • delivery using the cloud services. 

Which one is more suitable for the business?

When organizations apply such security models, they often become confused about which security model is more promising to protect a network’s data. Remember that Zero Trust Network Access and SASE are not competing security models. Instead, ZTNA is a part of overall SASE cloud services. 

A Zero Trust approach is a short-term objective to protect the software environment of businesses, whereas SASE is a long-term Security Posture. You decide to invest in the SASE approach and gradually advance your network and security towards SASE infrastructure. SASE is a time-taking process as designers detail all the technologies and solutions you can combine into cloud services to protect a network’s security.

Both Zero Trust and SASE are security stances of equal importance, as they are connected to devise a powerful Security Posture. Organizations should adopt Zero Trust principles to secure remote workforces and view all new networking projects through the lens of SASE. 

SASE devises a framework that makes the Zero Trust approach more flexible and easy to manage. Zero Trust provides better insight, whereas SASE offers better protection than traditional security systems. You can manage all aspects of technology through SASE. Zero Trust is valuable as it shows every attempt to access the network. It helps to know which users and devices are entering the software network and accessing data at any time. In this way, it reduces vulnerabilities. On the other hand, SASE manages a network’s groundwork from one location. It provides a better management platform for businesses.


To conclude the above discussion, entrepreneurs can better secure their complex networks data by combining both approaches. Zero Trust significantly eliminates security risks but is only valuable when implemented across the entire network’s infrastructure. That’s when the SASE enters into the picture.

The zero Trust approach eliminates the risk of all potential attackers, and SASE helps entrepreneurs devise a system that spots at-risk areas and circumvent the possible attacks. SASE provides better data analytics. It not only provides a higher level of protection than a typical security solution but is money-saving as well.
