In the evolving digital landscape, traditional networking solutions like Multi-Protocol Label Switching (MPLS) are increasingly becoming outdated for companies with widespread operations. The shift towards more flexible, scalable, and cost-efficient technologies has popularised software-defined wide area network (SD WAN) and Secure Access Service Edge (SASE) as alternatives or complements to MPLS networks.
Traditional WANs cannot handle the demands of global, distributed work, which requires fast, uninterrupted data transmission over long distances. In response to these challenges, SD WAN emerges as a more cost-effective, manageable, and adaptable solution compared. Unlike MPLS, which has its benefits, SD WAN offers greater flexibility to meet these evolving networking needs.
Comparative Overview: MPLS, SD WAN, and SASE
MPLS routes packets through fixed paths, which enhances connectivity but comes with higher costs and setup times due to its reliance on hardware. On the other hand, SD WAN, which uses software, connects LANs across various network channels more affordably and flexibly, not limited to the internet. It can also be used alongside MPLS in a hybrid setup.
To delve deeper into SD WAN, unlike MPLS, SD WAN does not require physical infrastructure to route data, which significantly lowers setup costs and increases the speed with which businesses can deploy and modify their network configurations. This flexibility is crucial for companies that require rapid scalability in response to changing business needs.
While SD WAN offers enhanced connectivity and cost-effectiveness, achieving robust security often necessitates additional services to protect against evolving cyber threats. In contrast, SASE provides a more integrated solution by embedding advanced security functions like Zero Trust directly into its network framework, ensuring comprehensive protection and simplified management.
SASE merges SD WAN with security functions (e.g., Secure Web Gateway, Cloud Access Security Broker, Firewall as a Service, Zero Trust Network Access) into a cloud framework, offering network and security from the cloud. This setup links users, including those remote, to the closest cloud gateway, ensuring secure, seamless access and visibility into data traffic.
Beyond simple integration, SASE’s cloud-native nature allows it to offer enhanced security measures that are uniformly applied to all network traffic, regardless of its origin. This is particularly advantageous for organisations with a high number of remote employees or those that rely heavily on cloud-based resources.
SASE streamlines network and security management, moving the perimeter from data centres to the cloud. This shift to on-demand cloud capabilities reduces the need for multiple perimeter devices, enhancing traffic flow.
Additionally, as a cloud solution, SASE dynamically adapts to business needs, cyber threats, and technological changes.
Evaluating Performance, Cost, Reliability, and Security
Performance and Reliability
SD WAN and SASE are designed to significantly enhance network performance by optimising traffic flows, which are crucial for applications reliant on cloud services. SASE extends these benefits by providing direct cloud access, which minimises latency and removes bottlenecks, ensuring faster and more reliable connectivity.
Security
SD WAN and SASE both improve security but take different approaches. SD WAN may require additional layers for full security coverage, while SASE integrates comprehensive security features like Zero Trust directly into the network infrastructure. This built-in security facilitates seamless protection across all access points, simplifying the management of network security protocols.
Cost Efficiency and Scalability
Transitioning to SD WAN and SASE can lead to considerable reductions in costs by decreasing dependence on physical hardware. These technologies offer greater scalability, making them ideal for businesses looking to expand or integrate a growing remote workforce. Their cloud-native designs facilitate quick deployments and integrate seamlessly with existing infrastructures, further cutting operational costs.
Which is right for your business?
Assessing business needs, goals, networking, and security requirements is crucial when choosing the right solution. The selected technology and frameworks must align closely with your business objectives.
Understanding the structure and needs of your organisation is key in picking the appropriate technological framework. Businesses with numerous branches and remote or hybrid workers, currently utilising MPLS or those yet to adopt SD WAN, may find SASE suitable.
As companies increasingly employ remote workers globally, traditional network perimeters are no longer visible. In such scenarios, integrating SASE with SD WAN offers a holistic approach to security, network management efficiency, and uninterrupted connectivity. It’s vital to consider not just the current needs but also future growth potential in your technology choice
