Secure Access Service Edge (SASE)

What Is Secure Access Service Edge?

Secure Access Service Edge (SASE) is a framework of security practices, tools, and technologies that work together to offer network security functions for the cloud. SASE solutions help close security gaps so that network perimeters remain secure when cyberattacks happen.  

As more companies switch to faster and more scalable cloud and connected Internet of Things implementations, there is a growing need to support an evolving trust and secure access environment.

Outside of enterprise, consumers are also adopting digital tools at a fast rate. Banking apps, crypto wallets, and digital payments provide users with new ways to pay; SaaS products improve productivity, and collaborative tools provide real-time communication across the globe.

Traditional approaches to verification and authentication rely on data centers and endpoints to maintain security. But cloud computing and edge implementations require a new way of thinking about network security. 

Benefits of SASE

Reduced IT Complexity

IT security implementations are simplified and enhanced with a holistic approach to network security and establishing trust with users and devices. Plus, 75 percent of organizations outsource SASE management services so that IT can focus on other responsibilities. 

Seamless User Experiences

Other network security postures slow down connections and limit user access to data and resources. SASE intelligently manages connections at the user level to optimize cloud services and ensure low latency. 

Reduced Cybersecurity Risk

As a cloud-native solution, SASE is designed to address new risks and challenges presented by distributed users and applications in modern organizations. It helps reduce the potential attack surface of the network with threat protection, authentication, and data loss prevention at its core.

SASE Features

Layers of protection and modern authentication practices with SASE allow businesses of all sizes and industries to build a secure network for software-defined perimeters and cloud implementations.

The main components of SASE: 

  • Centralized management
  • Zero Trust Network Access (ZTNA)
  • Software-defined wide area network (SD-WAN)
  • Cloud access security broker (CASB)
  • Firewall as a service (FWaaS)
  • Secure web gateway (SWG)


With new frontiers like blockchain and the metaverse come new challenges, such as ransomware gangs and questions about data privacy. SASE is a new approach to cybersecurity that relies on modern trust policies and a layered security strategy that extends to all devices on a network, no matter where they are located. ZTNA is a crucial component of SASE because it helps enforce the secure network perimeter at the user level. Without ZTNA, SASE wouldn’t be possible. 

ZTNA and SASE acknowledge that the most significant threats involve access and authentication. By taking security to the edge, organizations can eliminate these risks and implement a resilient cybersecurity strategy.
