As the world is changing, the workforce has begun shifting to distributed locations. This teleworking model, ultimately, has accelerated the need to adopt multi-cloud platforms and services, which already caused security concerns to arise and compelled the companies and IT professionals to rethink their security approach.

SD-WAN is apparently most organizations stick with; the NetworkWorld 2020 research shows that over 70% of the organizations are either researching or already have SD-WAN in production.

While the software-based SD-WAN is mostly relied on by organizations to help manage the connectivity and services across geographically dispersed data centers and branches, what challenges them is the lack of security/access control to protect their enterprise network in the cloud. Turning to multiple- point security alternatives, the companies are confronted with complex administrative issues, increased costs, and management complexity. At the same time, with nearly 70% of enterprise organizations migrating data for ERP applications to the cloud, stated in a 2019 report by the Cloud Security Alliance, the need for a comprehensive security solution for the use of public clouds is even imminent.

SASE Defined

Hence proposed by Gartner a new enterprise cybersecurity model for cloud-based networking — Secure Access Service Edge (SASE). This new technology category can combine the capabilities of a network with comprehensive security point solutions, such as firewall as a service (FWaaS) and Zero Trust network access (ZTNA), into a cloud-native mobile service.

SASE Versus SD-WAN Comparison

The two networking technologies, SASE and SD-WAN, though very much different in nature, serve the same purpose of connecting distributed endpoints to a central point where resources and services are available. You can look at their difference as that of files sharing between within an intranet and over Dropbox service:

Purpose To connect distributed organizations in a flexible approach

A new term coined by Gartner in 2019.

Steady growth has been observed ever since COVID-19 pandemic


To connect individual endpoints to the cloud as the center of the network

To connect geographically separate offices and to the headquarters while allowing for direct user access to the cloud.

Architecture A distributed architecture composed of endpoints as private data centers or as a cloud A centralized architecture in the headquarters (usually managed remotely by the service provider)
Where networking or security functions reside Endpoints Center
(in boxes at a headquarters or virtualized networking devices throughout the network)


It is no doubt the convergence of SASE and cloud-managed SD-WAN can best represent and carry out the ideal distributed, flexible, adaptive, and agile cloud-based solution. SD-WAN is a prerequisite on the path toward secure network transformation, due to its unquestionable capabilities to optimize bandwidth and ensure connectivity in mission-critical mobile environments.

Benefits of SASE and SD-WAN Convergence

With SASE combined with SD-WAN, enterprises can benefit from:

  • Simplified network infrastructure and management
  • Comprehensive and consistent security approach against cyberattacks
  • Reduced costs with a single unified platform
  • Fast deployment of delivering protection without the need to set up traditional IT infrastructure
  • Immediate secured user access to the enterprise network
