Secure Access Service Edge (SASE): Part II

Back on January 29th, we posted about SASE and SD-WAN, with a focus on SD-WAN. This article will build off the SD-WAN overview and dig deeper into Secure Access Service Edge, or SASE (pronounced sassy).

SASE has been called a concept, a framework, or even a solution, and perhaps these are all fair ways to describe SASE. SASE is combining security and networking functionality, and really is compromised of the following:

  • Secure Web Gateway (SWG): a cloud-based web proxy or secure web gateway provides malware detection, file sandboxing, dynamic threat intelligence, SSL decryption, and app/content filtering along with Data Loss Prevention (DLP).
  • Cloud Access Security Broker (CASB): a software to control and secure access to cloud-based or Software as a Service applications.
  • Firewall as a Service (FWaaS): a cloud-based delivery of firewall functionality to protect non-web Internet traffic.
  • Zero Trust Network Access (ZTNA): my personal favorite, the security framework focused on the “never trust, always verify” security approach. Zero Trust network access verifies the user’s identity and establishes device-based trust before granting the user access to authorized applications.
  • And SD-WAN

I recently watched a video with the SVP and GM of Cloud and Network Security from Cisco – Jeff Reed.  It was a short Q&A but insightful. With the global move to remote workers, technologies like Secure Access Service Edge (SASE) have been accelerated from an adoption perspective. SASE is a combination of network and security functions. For many, many years we have spoken about the need to consider security with all architectures, but with SASE, they are really integrated and part of the core design.


Here at Greyson Technologies, we see SASE as an emerging technology focus, which will be taking a spot with many organizations ’ IT budgets. As applications and data move to the cloud, coupled with more and more mobile users, we need to look at new solutions to meet these new demands. Interested in learning more about how we can help you?
