What is SD-WAN?
The Software-Defined Wide Area Network (SD-WAN) simplifies the wide-area network’s management, operations and resilience.
From communication providers to enterprises, SD-WAN aggregates transport services, MPLS, LTE, broadband internet services, i.e. virtually any type of WAN link. SD-WAN facilitates a secure connection among the application users.
How Does SD-WAN Work?
Using a centralized interface, SD-WAN ensures security and reliable connection across the WAN, typically the last-mile.
It offers application-aware and user-aware routing throughout the WAN, allowing applications to receive QoS and security policy enforcement accordingly. With SD-WAN, users can experience improved application performance.
It provides multiple security layers while maintaining excellent cloud performance on the local internet breakout of IaaS and SaaS application traffic. Ultimately, improving the user experience contributes to increasing productivity, scalability, eliminates challenges for IT.
SD-WAN vs MPLS
Essentially, the differences between SD-WAN and MPLS revolves around virtualization. SD-WAN virtualizes network functions on the network infrastructure allowing those functions to run as software on any commodity hardware whereas MPLS requires proprietary hardware.
This key difference in the way SD-WAN virtualizes network functions results in a less expensive, higher performance solution that also provides a higher level of security. MPLS comes with extremely high bandwidth costs which is simply not an issue for SD-WAN.
These crucial benefits are why IT infrastructure across industries continues to switch away from MPLS to SD-WAN.

SD-WAN Architecture
SD-WAN’s abstracted architecture, is arranged into two parts: the control plane and forwarding plane. SD-WAN architecture places the control plane in a centralized location to help teams manage it remotely. In this way, you can control the SD-WAN architecture without requiring the assistance of the IT team.
The Three Primary SD-WAN Components
SD-WAN Edge
The endpoints of the network are on the SD-WAN Edge. These endpoints can either be a branch office, remote data center, or a cloud platform.
SD-WAN Orchestrator
As the virtualized manager for the network, SD-WAN Orchestrator coordinates traffic and applies the policy and protocols. The operators execute these security protocols.
SD-WAN Controller
SD-WAN Controller is the center for network management. This controller allows you to oversee the network in its entirety to be able to generate policies.

The Three Types of SD-WAN Architectures
On-Premises SD-WAN
On-Premises SD-WAN is where the SD-WAN hardware can be found on-site. This hardware allows the network operators to manage the network without having to utilize the cloud directly. This direct access is ideal for handling confidential information that cannot risk getting sent over the internet.
Cloud-enabled SD-WAN
From its name, cloud-enabled SD-WAN requires a connection to the internet to manage a virtual cloud gateway. This cloud makes the network more accessible to others with its improved integration and performance towards cloud-native applications.
Cloud-enabled + Backbone SD-WAN
Cloud-enabled + backbone SD-WAN provides an additional back-up to the architecture, which allows the on-site architecture to connect to the SD-WAN provider’s closest point-of-presence (POP). It facilitates efficient traffic switching from the public internet to a private connection without a hassle. You can always ensure low levels of latency, packet loss, and consistency if the connection becomes overwhelmed.

Secure Access Service Edge (SASE)
A Holistic and Assured Approach to Enterprise Networking
In an increasingly segmented digital security landscape, there is a growing need for companies to streamline their cybersecurity solutions with a more holistic approach that doesn’t compromise
What is SASE?
SASE is a network architecture for the edge and access network which provides flexibility to route directly to the desired application based on criteria such as where the application is hosted and whether the user has permission to access that application. Today, remote locations typically route back to HQ to the installed corporate firewall and then trombone to the cloud for the required application. SASE optimizes this routing, layering on much needed security to inhibit cyber-attacks and combat ransomware attacks.
Secure Access Service Edge (SASE) is a network architecture that combines software-defined wide area networking (SD-WAN) and security efforts into a single, cloud-centric simplified WAN deployment. This relatively new network security approach is revolutionizing how enterprise businesses store and secure data, users, and resources.
SASE operates on the “edge”, meaning that SaaS security and network resources are as close to the end user as possible. This makes it an opportune choice for enterprises with remote teams. SASE Managed Service Providers help businesses by keeping resources in data centers closest to their employees. This improves employee productivity by reducing latency, increasing throughput, and making services more responsive. In addition, some SASE solutions have encryption and zero trust security built-in, therefore avoiding cumbersome VPN tunnels and bottlenecks at the corporate firewall.
Why SASE?
SASE is easily scalable.
Because of its cloud servicing, SASE can be billed based on how much a company uses. Companies can pay for what they use, and there’s room for more or less depending on needs.
Enterprises deal with fewer vendors.
SASE streamlines the complexities and costs associated with network infrastructures. There’s less hardware needed in offices or other remote locations.
Simplifies authentication while increasing security.
IT and telecoms leadership can set policies through the cloud-based platforms and have those policies enforced at the end user. End users won’t have any interruption in access experience, regardless of if they’re remote or in-office. Security gets a boost because policies are enforced equally, no matter a user’s location. Cloud service providers constantly look for security protocols — no new hardware required from an enterprise company.
Security at Network Edge
Does SASE mark the end of the network as we know It?
Yes, but we will still have IP packets and routing. These are seen more as sessions that reflect business functions for which we use a network, whether they be voice calls or HTTPS sessions.
If so, in what way(s)?
In as much as SASE will mean the firewall function will be distributed throughout the access and edge network. The network architecture and topology will change. Instead of all traffic going via HQ or a specific rented corporate data centers, sessions will go directly to where they processed or can derive services. This will mean better response time, lower latency, and better throughput because of reduced tromboning and load on those fixed central points of congestion.
What are SASE’s key benefits?
Security: Zero Trust Networking (ZTN). Precise control of who is permitted to join the network, with what type of device, to access which server, and for which part of what application.
Efficiency: Some SASE solutions are session based by nature. This means fine granularity and control of which users can reach which services, e.g., some users may access corporate web services but will not be permitted to go to databases containing confidential information.
User Experience: Traffic will be routed directly to the data center supporting the service required . Everything benefits from moving intelligence out to the edge. For example, if the user needs to access Microsoft Office365, publicly hosted collaboration services, or Microsoft Teams voice services, their traffic will go directly to those public clouds. If they need to access an internal corporate database or application, that traffic will go directly to the corporate data center if authorized. This will greatly benefit work from home, field-based employees, and branch office workers.
How long before SASE becomes a dominant technology, if ever?
SASE becomes inevitable if you believe:
- We are becoming a more mobile flexible workforce [in other words the gig economy] and work from home (WFH) is here to stay
- Migration to the cloud is irresistible for businesses owing to reduced costs, continuous software upgrades, centralized expert management of IT assets running on flexible virtual fabric & better ML/AI derived from greater volumes being consolidated in cloud
- The sophistication ransomware and cyber-attacks is multiplying year on year and greater protection is needed
- Work from home (WFH), at least fractionally, is here to stay.
Two Vital Takeways
- Implementing SASE with IPsec-based SD-WAN tunnels does not scale. Both in terms of session establishment and the packet overhead associated with IPsec tunnels makes them cumbersome and unreliable compared to a session-based routing scheme that uses existing IP protocol headers mechanisms in a more flexible way with encryption.
- Encrypted voice from remote workers should go directly to a Session Border Controller which is a purpose-built firewall for SIP-based voice communications. Firewall are optimized to manage data communications. SBCs are optimized by experts in SIP communications to manage voice communications. installing the SBC behind the firewall adds complexity, performance obstructions and introduces support challenges.
