Since the last decade, networks have been instrumental in connecting users to applications via data centers. These data centers are protected by a security layer to safeguard apps and data from the outside world. But now things are different.

With all the enterprise data being pushed to the cloud, the conventional security standards are getting outdated. With users connecting from literally anywhere, conventional network security practices are no longer able to solve the fundamental security problems and are only adding to the increased complexity.

At the same time, businesses have to constantly collect sensitive information of their customers, and deploy it to the cloud. The safety of this data in the cloud totally depends upon the data security approach you take and the tech architecture of your business.

One such fantastic approach that protects your data at all endpoints is Secure Access Service Edge or simply SASE.

In this post, we will understand everything about SASE including how it mitigates breaches, misconfigurations, and internal errors.

  1. What is SASE?

What is SASE?

SASE which is an acronym for Secure Access Service Edge is a cloud-based approach for securing WAN networks. It is a robust network architecture that works by combining the Wide Area Network capabilities with cloud security functions such as web gateways, cloud access security brokers, and zero-trust network access.

The SASE network architecture provides better visibility of the users, traffic, and data of entities accessing a corporate network from any location or any device. In this way, SASE helps your company cut down deployment and networking costs and also improve external security, at the same time. SASE typically works with SD-WAN; this provides enterprises a WAN networking functionality by passing information securely across the network.

Traditional WAN networks allowed users in a branch or campus to connect to data and applications via data centers using MPLS hardware. This provided reliable connectivity and security. But remember that MPLS is nothing but a data forwarding technology that controls the flow of traffic in a network. More importantly, installing MPLS hardware can be quite expensive and it does not work in a cloud-centric environment.

Components of SASE

SASE is not made of a single component. It is an entire toolbox of the following components providing security within a global network -

  1. SD-WAN — As mentioned earlier, SD-WAN is an important component that provides optimal routing in a client to cloud platform.

Benefits of SASE

  1. It provides a holistic view of your entire business network so that you can identify your users and data resources effortlessly, that too at a large scale.

Is SASE necessary for your business now?

With businesses rapidly shifting their data assets to the cloud and WFA being the new norm, there is a rapid increase in unmanaged devices within the corporate network. These unmanaged devices are hard to track within the corporate network. With SASE, your business can track the devices present in your corporate network and set security policies to surf within your network. Also thanks to the least privilege access provided by SASE, the possibility of an attack is minimized to a great extent.


With everything becoming a part of the cloud in today’s world, providing security and seamless user experience is the main requirement for all enterprises. And offering security can be taken care of by SASE. Although there are some shortcomings, SASE can do more good to your enterprise than harm as it comes in as a bundled technology, offering various security features to cloud-based platform access.
