SASE In Practice: 7 Scenarios Where It Beats Traditional Approaches

Secure Access Service Edge (SASE) represents a fundamental shift in how businesses protect and connect their digital operations. As organizations accelerate their digital initiatives and cloud adoption, traditional network and security approaches like MPLS and traditional WANs are proving inadequate for today's dynamic business needs in the era of the cloud. Below are seven use cases that demonstrate how SASE delivers strategic advantages over conventional networking and security approaches.

Use Case #1: MPLS Migration to SD-WAN

Multiprotocol Label Switching (MPLS) networks are known for their reliability and performance. While MPLS has certainly served enterprises well for over two decades, it comes with high costs and little adaptability. Think of MPLS as a subway system for your workloads that provides fixed routes and stations with reliable and predictable service.

Now think of SASE as a ride sharing alternative that offers dynamic routing based on current conditions as well as flexible pickup and drop-off locations. Consider that in addition to its ability to adapt quickly, it can significantly reduce costs and improve performance at the same time. Here is what transitioning from MPLS to SASE can provide for a typical business:

• Replace expensive dedicated MPLS lines with more affordable high-speed internet connections
• Reduce operational costs through simplified management
• Faster expansion capabilities for your business as SASE can get new offices online in days or even hours vs. the elongated process of MPLS
• Automatically routes traffic through the fastest path
• Improve access to both cloud services and your own data centers

The bottom line is that SASE gives you enterprise-grade network performance and security at a lower cost than MPLS, while being much faster to deploy and easier to manage.

Use Case #2: Optimized Global Connectivity

SASE offers a compelling solution for organizations grappling with high-latency and inconsistent network performance across their global footprint. Its architecture leverages a vast network of Points of Presence (PoPs) that function as strategically placed access points for users. Benefits to your business include:

• Reduced latency for global users of latency-sensitive applications like VoIP and video conferencing
• Cloud services that deliver uniform performance across international borders with smoother interaction
• Improved performance of collaboration tools for teams dispersed across different countries

Use Case #3: Secure Branch Internet Access

There is no doubt that the increased use of cloud applications and internet traffic has made securing the typical branch office challenging. SASE delivers a complete, built-in security stack directly from the cloud, protecting all branch traffic without the need for individual on-site security appliances. For your business, this means:

• No need to buy and manage security hardware at each office
• One unified set of security policies across all locations
• Security upgrades and updates are handled by the SASE provider, thus reducing the management burden of your internal IT Team.

Perhaps the biggest benefit is the fact that your organization can kiss the concept of backhauling all your internet traffic to a datacenter or regional hub goodbye. It isn’t necessary anymore thanks to SASE. Not only does that translate into reduced latency but also provides an enhanced user experience for your branch office employees.

Use Case #4: Secure Branch Internet Access

What matters most in real estate is location, location, location. That applies to cloud computing as well. The faster you can access workhorse cloud applications, the more productive your users can be. SASE providers strategically position their PoPs to maximize cloud connectivity. In fact, often times these PoPs share the same datacenter footprint as major cloud providers (such as AWS, Azure, Google Cloud, etc.). This co-location results in near-zero latency between SASE and cloud services. That is like having a dedicated fast lane connected to your cloud service providers, meaning that you don’t have to trod along in the crowded regular lanes that everyone else is taking. For your business this means that:

• Better performance than both public internet and traditional MPLS
• Creates near-instant connections to cloud services
• Reduced costs and complexity as SASE eliminate the need for costly MPLS circuits or additional cloud appliances.

Now add greater flexibility, as administrators can define application-level rules within the SASE platform that determine where cloud application traffic should exit the SASE network. With SASE, security doesn’t have to be complex.

Use Case #5: Remote Access Security and Optimization

It isn’t just on-prem branch users that were stuck with the one-size fits all MPLS architecture to address their hybrid workloads. Remote users were stuck with legacy VPN for remote access. While branch users were constrained by inflexible MPLS architecture for hybrid workloads, remote users faced similar challenges with legacy VPN solutions. SASE offers a more sophisticated approach as it employs Zero Trust Network Access (ZTNA) technology. Rather than granting access to the entire network like legacy VPN, it allows the granular control to authenticate users to specific resources. This means that:

• Each user only sees and accesses what they're authorized to use
• The risk of lateral movement within the network is reduced
• Remote users experience security and performance equivalent to office-based workers
• Elimination of slow or unreliable VPN connections

At the same time, it may come as a surprise as this heightened security comes with a simplified user experience. That’s because a single mobile client software provides access to all necessary resources, streamlining the process for remote workers.

Use Case #6: Work from Home

As you may be recognizing, SASE architecture is designed to provide an optimal experience for users within hybrid enterprises. This is especially true for work from home workers. By implementing SASE, organizations can provide their work-from-home employees with a seamless extension of the office environment. Thinks of it as enterprise-grade home access that ensures:

• Employees get the same fast, secure connection they had in the office
• Security automatically follows the respective worker home
• Reliable access to both cloud and company applications

SASE surpasses traditional VPNs by providing a cloud-scale infrastructure capable of supporting thousands of concurrent connections, ensuring seamless access for all remote employees. By incorporating self-service provisioning, consistent security policies, and continuous threat inspection, SASE has established itself as an ideal solution tailored for the demands of the hybrid work era.

Use Case #7: Consolidate and Streamline Networking and Security Management

People tend to gravitate towards the simpler solution. SASE provides streamlined simplicity as it consolidates network and security management into a single platform. eliminating the need to juggle multiple consoles. With SASE you can:

• Configure, manage, and report on the entire infrastructure from one interface
• Gain a holistic view of the network and security landscape
• Reduce time spent switching between different management tools

In the face of the growing complexity of business networks today, SASE streamlines the management experience, making it easier for IT to optimize the user experience.
