A Successful SD-WAN Implementation Plan Has These 5 Components.


Because they want quick, scalable, and flexible communication between various network environments, more enterprises are looking into SD-WAN solutions. However, picking the incorrect SD-WAN solution may hinder your ability to quickly adjust to shifting business demands. It may also result in unforeseen security difficulties.


Five Requirements for a Secure SD-WAN Implementation


These five factors should be taken into account for a successful Secure SD-WAN installation, whether you are contemplating SD-WAN for the first time or revising your present approach.


1. Work from any location (WFA)


Numerous employees were sent home due to the COVID pandemic, which increased the demand on networks and IT. And even though many people anticipated going back to work, the work-from-home paradigm has developed into a mixed work model in many firms. Employees can now work remotely, from a home office, an office location, or via a mobile device. However, putting this work-from-anywhere (WFA) approach into practise can be challenging. Due to the necessity of balancing experience and security, it raises the level of network complexity. Furthermore, no matter where they are or what device they are using, users must have the same experience when using applications and collaboration tools.


SD-WAN systems should include a ZTNA Access Proxy to support WFA. ZTNA improves security and visibility across all users, programmes, and devices, on or off the network, and gives a better user experience than a VPN. ZTNA provides a single security policy across all network edges to ensure uniform attack surface protection.


2. Scalability that is dynamic


Agility is a requirement for firms to meet digital transformation goals. Many have chosen hybrid and multi-cloud methods and created new intelligent edge resources with this in mind. SD-WAN must provide on-demand connectivity between corporate headquarters, branch sites, home offices, and multi-cloud environments to scale to any environment or workload. To be ready for future development, the SD-WAN solution should scale to thousands of sites. To make management at scale simpler, it ought to have a single-pane-of-glass management system.


AIOps can streamline troubleshooting, spot abnormalities, and forecast different kinds of failure based on machine learning models. Additionally, enterprises may quickly scale while reducing overhead costs and boosting productivity thanks to day-0, day-1, and day 2+ networking procedures that are simplified.


3. Performance of Clouds


Businesses with a hybrid or multi-cloud strategy should search for an SD-WAN solution that can solve cloud connection if they want consistent security and performance on and between various cloud platforms. By enabling quick, secure connectivity to the cloud and maintaining high performance there as a native solution as well as across clouds by federating inter-cloud protocols in real-time, it should make cloud on-ramp simpler.


4. Edge Security


Because SD-WAN connections are so dynamic, systems must be able to track bandwidth usage and packet loss and alter connections in real time. However, a lot of overlay-deployed security solutions aren’t scalable. Security lags behind network changes, which leads to connection flexibility restrictions and security flaws.


Advanced security and routing capabilities are combined in an SD-WAN system that uses a security-driven networking strategy. Whether built-in or SASE-based cloud-delivered security is used, these solutions can enhance operations and offer reliable protection.


Regardless of delivery mechanism, the same security stack should be in place to secure outgoing traffic and stop lateral threat flow. Because the solution must analyse encrypted information in real-time, companies should search for solutions that give maximum speed even for thorough traffic analysis.


5. Branch Assistance


The branch office’s outermost boundary is not where security and connection terminate. To monitor and protect connectivity and transactions over the local area network, a good SD-WAN solution should extend its fundamental capabilities further into the branch network.


Together, SD-Branch and SD-WAN should be used to create a safe and managed distant branch by integrating security, WAN, LAN, and WLAN into a single system at dispersed sites. As a cellular gateway, it should also support LTE and 5G in order to improve availability and resilience for SD-WAN deployment.


Creating a Strategy for SD-WAN That Can Meet Needs Now and in the Future.


You should think about your organization’s present and future needs when searching for an efficient SD-WAN solution. Your chosen solution should offer complete, end-to-end security, allowing IT professionals to effortlessly monitor, enforce, and maintain network control even as business and connectivity needs change.  And it must accomplish all of this without the use of numerous complexity-adding add-ons, overlays, or workarounds.
