Take a look on SASE (Secure Access Service Edge)

April 17, 2021 ,

Today We are going to talk about the SASE (Secure Access Service Edge). As we say that SASE stands for Secure Access Service Edge and is a new approach of network security that is changing the way industries protect the data, resources, and users present in their networks. 

SASE described as cybersecurity concept that Gartner described in the August 2019 report. SASE is the convergence of WAN and network security services like CASB, FWaaS and Zero Trust, into a single, cloud-delivered service model.

So what are we going to achieve with the SASE?
We come up with the Next generation networks and now we want to simplify the next generation network on the cloud with the security features. 

We can implement and deliver security services as threat prevention, web filtering, sandboxing, DNS security, credential theft prevention, data loss prevention and next-generation firewall policies on cloud based deployment without getting hardware purchased which gives the customer a flexibility to get a secure network within a single box deployment. 

The important thing in these kind of deployments are Zero trust and data protection. SASE solution approach to the cloud removes trust assumptions when users, devices and applications connect. A SASE solution will provide complete session protection, regardless of whether a user is active or not active on to the network.

What Are the Benefits of SASE?

SASE is really a good initiative and simplify the network with all the features in a cloud based service product.

  • Cost: It will definitely reduce costs by deployment is on the cloud without any different vendor hardware and licenses models.
  • Performance: We will get the better network performance by using a global SD-WAN service with its own private backbone and built-in optimization
  • Secure: Security improvement and performance by inspecting traffic flow at the source (performance) and inspecting every data flow user (security improvement) Seeing policies based on identity.
  • Overhead: We can have now less overhead as SASE vendors run and maintaining the security on top of the Network services provided in the cloud based architecture. No more updating, patching, and scaling appliances.
