As of 2022, SASE continues to increase its popularity in the cloud-computing market. In the near future, SASE will become a go-to plan for many businesses. That’s mainly because every day more businesses adopt cloud, multi-cloud, and hybrid infrastructures and shift workloads to cloud.
Legacy technologies are no longer effective to protect cloud resources and they aren’t compatible with modern-day challenges. SASE architecture on the other hand is cloud-native and protects both on-premise devices and cloud resources while making the cloud accessible from anywhere in the world.
Nowadays, many businesses acknowledge the benefits of implementing the SASE framework. For some who have little knowledge about SASE, it is a cloud-based architecture that consists of five main components, and these are SD-WAN as service, Secure Web Gateway (SGW), Firewall as Service (FWaaS), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA). SASE unifies these as an integrated service, and all operate as one. In short, SASE isn’t a single product. Let’s look at the top five SASE use cases in 2022.
1- Improved Security For End-Point Users
Ever since the COVID-19 pandemic began, remote work models have become a new norm for many of us. With poor security measures, the remote force can increase the risks of potential cyber threats. But, SASE can help businesses to mitigate the risks associated with a remote workforce and reduce the surface areas of potential attacks.
SASE uses SD-WAN technology that allows end-points users to access cloud resources and company applications regardless of their locations. Additionally, SASE enables secure access for end-users via secure web gateways, and before granting access, ZTNA verifies users’ identities. So, SASE ensures that only authorized users can gain access to the resources.
2- Enhanced Cloud Data Security
As of 2022, more than 60% of corporate data is stored in the cloud. Nowadays, securing cloud data, resources, and applications are more important than ever. SASE architecture provides enhanced security for cloud-based resources, applications, data, and on-premise devices. SASE aims to secure all the edges and endpoints in the cloud.
SASE segments the network creates multiple checkpoints and removes the areas that contain sensitive data. SASE controls users’ access to corporate resources and doesn’t allow unauthorized users to access sensitive data. Cloud Access Security Broker protects cloud-based resources and hides SaaS applications behind next-generation firewalls. In short, SASE ensures enhanced cloud data security via multi-layer security components.
3- Network Expansion Is Scalable
Over time, businesses’ needs can change, and SASE can help them seamlessly scale network expansion that is aligned with their growth. Businesses can add or remove users, devices, and even applications’ access privileges at any time. IT admins can control the complete system from a single place and manage users’ identities and access privileges easily. Additionally, Zero Trust limits users’ access to the corporate networks. In short, with SASE, network expansions of the businesses are scalable and compatible with their growth.
4- Wider Visibility of Cloud Data
While using legacy technologies, it is almost impossible to see who is accessing which data, when, and from where. But, SASE enables wider visibility of cloud data, both historical and on time. It helps businesses to manage the data flows, and better understand the range of the data landscape.
SASE includes Data history tools that scan historical data to detect areas that can present security risks. Additionally, SASE both controls and monitors the user-generated traffic in the cloud. Monitoring tools can detect security threats in any cloud applications on the SD-WAN, and isolate these threats at once.
5- Behavior Monitoring of End-Point Users
Modern-day businesses are always up against cyberattacks, and cloud systems should be protected from malicious intrusions of all kinds. Behavior monitoring can help you detect anomalies quickly and respond to possible threats at once. With the SASE framework, IT admins can track users’ activities, and see log-in times, locations, and devices.
For example, when SASE detects abnormal behavior or suspicious activity, it alarms IT admins, and doesn’t permit lateral movement, so it reduces the surface area of attack. Additionally, behavior monitoring can help businesses to prevent potential breaches that can stem from an organization’s staff as their suspicious activities will be detected quickly.
Last Remarks
In today’s world, most businesses’ main concern is security because everyday cyber-attacks become more common. Additionally, latency technologies are no longer effective to protect cloud environments. In most ways, SASE architecture is more sustainable and effective for securing both cloud and on-premise resources.
