Unraveling the Future of Network Security: Secure Access Service Edge (SASE)

Gartner, a global research and consulting company, coined the term “SASE” in 2019. It was introduced by Gartner researchers Neil MacDonald and Joe Skorupa. SASE is a cloud-based computing model that combines networking and security services. It combines network security functions (such as SWG, CASB, FWaaS, and ZTNA) with WAN capabilities (i.e. SDWAN) to support the dynamic secure access needs of organizations. It provides an approach to secure the WAN natively in the cloud, replacing the need to run security in the old centralized data center.

By building modern digital businesses, it is predicted that 40% of businesses will implement explicit strategies to adopt SASE by 2024, as businesses and organizations face economic and operational uncertainty in every industry and sector. Now is more than ever time to understand compliance, adjust expectations, refocus and reposition yourself in the wake of the next normal. In this alarming situation, it is high time for organizations to navigate to a new normal in order to counter and meet challenges and grow their businesses with new perspectives. The COVID-19 pandemic has made the tech industry different. In times like the current pandemic, these solutions are acting like a scientist in terms of business continuity. The tech industry has always weathered crises and found new ways to come out stronger every time. In fact, tech companies have paved the way for various strategies that other industries are now using to deal with this crisis.

SASE offers several advantages over a traditional data center-based network security model. It offers many potential benefits to organizations, such as reduced complexity and increased cost savings, improved security, simplified policy management, identity-based network access, and it also benefits from low latency and speed. ‘better bandwidth. SASE is more than just technology; it is a comprehensive set of technologies that integrates security into the overall structure of the network so that it is always available, no matter where the user is located, where the application or resource is accessible. It is comprised of five main technologies: SD-WAN, Firewall as a Service (FWaaS), Cloud Access Security Broker (CASB), Secure Web Gateway, and Zero Trust Network Access.

SD-WAN: SASE relies on SD-WAN to provide network functionality that reaches users and applications at the edge.

FWaaS: SASE uses FWaaS to put the traditional firewall in the cloud. It adapts elastically to the needs of the business, meaning that security policies can be applied across the network, regardless of where employees are working.

Cloud Access Security Broker (CASB): A CASB offers products and services to address security gaps in an organization’s use of cloud services. offers five critical security features such as cloud application discovery, data security, adaptive access control, malware detection, and user and entity behavior analysis (UEBA) that offers an application policies based on unusual behavioral patterns of traffic to / from cloud services.

Zero trust network access: The main function of ZTNA within a SASE solution is to authenticate users to applications. They use dynamic verification capabilities to allow users to access, upload or download sensitive company data.

A Secure Web Gateway (SWG): SASE uses SWG to protect a web browsing user device from infection with unwanted software or malware and by enforcing compliance with corporate and regulatory policies.

SASE represents a major paradigm shift and offers a lot of promise and a new way of doing networking and security for the modern business. The five practical steps businesses can take to get started with SASE are:

  • Secure your remote workforce
  • Place branches behind a cloud perimeter
  • Move DDoS protection to the edge
  • Migrate applications to the cloud
  • Replace on-premises security appliances with a unified, cloud-native policy enforcement

The meeting of digital transformation and increasing complexity has made many older approaches to digital security irrelevant. Gartner believes SASE is the future model for a secure corporate network. Without a doubt, SASE will be a major disruption to the network and network security architecture. As part of a global digital business transformation, organizations will look to SASE, but true adoption of SASE requires more than bundling existing unique solutions – it requires a complete overhaul of the company’s network infrastructure. business.
