All About SASE


What’s the one thing that the world is going gaga over after SD-WAN? Well, it’s Security Access Service Edge or simply SASE.

SASE (pronounced Sassy) is the new buzzword around town. But it is time to get a clear picture and understand what Security Access Service Edge (SASE) actually means.

Gartner was the first to coin the term in 2019, as an emerging cybersecurity concept. They defined SASE as “SASE capabilities delivered as a service-based upon the identity of the entity, real-time context, enterprise security/compliance policies and continuous assessment of risk/trust throughout the sessions. Identities of entities can be associated with people, groups of people (branch offices), devices, applications, services, IoT systems or edge computing locations.” 

In simpler terms, SASE is a model for improving business security. It involves a combination of software-defined edge networks, user-centric authentication and access control, and seamless integration between the clouds. Simplifying wide-area networking and security services by delivering both as a cloud service model.

With the change in times, today’s workplace is going through a 180-degree transformation, with an increase in remote and mobile employees along with the ever-increasing dependency on the cloud. At this crucial juncture of transformation, the SASE security model helps the organization identify users and devices and apply policy-based security to their location. In turn, helping organizations to adapt to the cloud, embrace mobility, deliver a superior user experience and protect against security threats


With the revolutionary change in the digital sphere today and an ever-growing increase in cloud usage and businesses moving to SD-WAN, a safer and reliable networking system, it is crucial to keep in mind that there is always a risk with this change in security. Risk management leaders are looking for ways to reduce these security risks.

Today many are now moving to the SASE architecture. SASE plays a role in combining the expertise of WAN with extensive security capabilities such as Cloud Access Security Broker (CASB, Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and Firewall as a Service (FWaaS).  

How has switching to SASE impacted businesses?

Opting for SASE has been making a huge impact on businesses. Making life easier and less complicated. Let’s see how this transformation helped many enterprises
