Even after employees begin returning to the workplace, companies continue to allow remote work in a hybrid working model. Security has become a priority as firms start to include remote work into their long-term goals. However, many businesses realize that their traditional security controls are inadequate for the cloud-native, remote workforce.

Data protection needs to be a key priority for large organizations halfway through their cloud journey and those just getting started. In this blog entry, we look at how current cloud-based solutions like SASE and Zero Trust can help businesses protect and connect their employees, regardless of where they work. To begin, we will look at what SASE and Zero Trust security are?

What is SASE?

SASE is a principle that brings protection to the users and devices themselves. It helps address some of the challenges due to the rise in remote employment and remote work. SASE suites use a cloud-based management system to handle the essential infrastructure and technology. (It can manage secure web gateways, SD-WAN solutions, firewalls, and cloud-access security brokers, among other things.)

Gartner created the concept to solve flaws in current cybersecurity methods, particularly with dynamic services, software as a service (SaaS), and distributed data. According to Gartner, SASE is identity-driven, has a cloud-native design, is globally distributed, and supports all edges.

What is Zero Trust?

Zero Trust is a security framework that mandates that all users, whether inside or outside the organization’s network, be verified, approved, and continually evaluated for security configuration and posture before permitting or maintaining access to applications and data. Zero Trust presupposes no distinct network edge; networks can be local, cloud-based, or a blend of both, with resources and workers located anywhere. Zero Trust is the answer to securing a perimeter-less organization where anyone can access the corporate network from anywhere using any device at any time. 

 Zero Trust is a framework for safeguarding infrastructure and data for today’s modern digital transformation. It is a unique product to meet today’s corporate concerns, such as securing remote workers, hybrid cloud settings, and ransomware attacks.

Mobility and Cloud Challenges

Applications, data, and users are now dispersed across locations and geographies, including data centres, the cloud, various software-as-a-service (SaaS) offerings, mobile devices, and so on. As a result, businesses find it challenging to have total visibility into their applications and data, much less govern and manage those who access these resources. 

Point solutions, such as secure web gateways, firewalls, and remote access VPNs, have been used by many organizations to address these issues. However, as more apps move to the cloud, traffic no longer requires a VPN, which creates a conflict because proxies and secure web gateways cannot tunnel traffic to private applications. So, businesses are looking for a remote access VPN solution to support cloud as well as data centre applications.

Zero Trust Network Access (ZTNA) has led to creating software-defined perimeter point devices that complement proxies in response to these requirements. These handle use cases involving private application access, but they also increase the number of point products deployed. Some also go through inspection that is generally applied to internet-bound communications, allowing them to get around the implementation of security standards.

SASE and ZERO Trust Working Together

Businesses of all sizes and industries face long-term problems of keeping data and infrastructure secure. Many workplaces are compelled to continue in a remote or hybrid operating model due to fears of COVID-19. Security teams must secure many more endpoints overextended geographies to support this remote model. Organizations are choosing a zero-trust approach and technologies to achieve this. Businesses are also incorporating Secure Access Service Edge to make their environment even more agile and secure (SASE).

SASE provides a central location for businesses and organizations to manage their technology and infrastructure strategies. They may streamline admin tasks, share data, and use analytics to get a 360 view using a management platform. SASE establishes the framework that allows zero trust to be flexible and manageable. Combining these two concepts is a recommended way for businesses to secure their dispersed data and apps.

Many organizations utilize zero trust because it enables them to obtain deeper insights. They can see at any time which users and devices are accessing the infrastructure and data. It also tracks all network connection attempts. Zero trust minimizes vulnerabilities due to increased visibility and access prevention. Furthermore, the strategy reduces the amount of human effort required of IT workers through automation powered by artificial intelligence.

Final Thoughts

Companies may achieve ZTNA with a single solution that combines SASE and Zero Trust principles to implement and enforce security policies across their entire network in a consistent manner.

The advantages of using SASE and ZERO Trust together are as follows:

  • Improved network safety
  • Streamlined network administration
  • Significantly lower costs associated with deploying security at scale
  • A single, comprehensive view of the entire network
