We are surrounded by acronyms and buzzwords in technology. SD-WAN is one that is often used in the industry nowadays.
Organizations embrace digital transformation to stay up with market developments, consumer needs, and competitiveness. Traditional network designs weren't meant to manage digital transformation workloads and complexity. Business-critical services are commonly spread over numerous clouds, compromising network performance, particularly at branch sites.
Smart network operations teams opt for SD-WAN. SD-WAN reduces overhead and improves network performance. Routing and hardware expenses are saved through SD-WAN solutions while allowing multi-cloud access. SD-WAN also reduces overhead and supports new digital apps and services. This new technology streamlines WAN administration and operation and brings corporate advantages.
Business Challenges that SD-WAN Addresses
There has been a dramatic increase in the pressure on the network as a result of digitalization. Businesses must now rely on a stable and secure network, which conventional router-based network topologies are incapable of providing. An SD-WAN solution assists businesses in addressing use cases in order to expedite digital transformation efforts, lower cybersecurity risks, and increase revenue.
Eases connectivity with far-flung factories and offices.
Effectively deploys new sites and minimizes network equipment sprawl.
Enhances the speed of file transfer and backups to disaster recovery facilities.
Helps in moving applications to the cloud and protecting cloud app. data using Secure Access Service Edge (SASE).
Safeguards IoT devices using a zero-trust network
Helps in complying with the cybersecurity framework of the National Institute of Standards and Technology (NIST).
Ways SD-WAN Can Help Businesses Boost their Bottom Line
Boosts Security
Digital transformation is a double-edged sword. It can increase consumer satisfaction and market reach, but can pose security threats. According to the U.S. State of Cybercrime study, 41% of respondents stated more cybersecurity occurrences in 2017. The good news is that many SD-WAN solutions provide built-in security. Most SD-WAN systems only offer basic firewall and VPN functionalities, requiring IT teams to add security to elastic and dynamic SD-WAN connections after the fact. SD-WAN solutions with NGFW, IPS, encryption, AV, and sandboxing can avoid data loss, downtime, regulatory violations, and legal liability.
Enables Cloud Usage
Cloud services are rapidly being used by businesses. The great news is that SD-WAN enables direct cloud access at the remote branch, removing backhauling traffic – which routes all cloud and branch office traffic through the data center – allowing workers to directly access cloud applications irrespective of location without burdening the core network with additional traffic to manage and secure. Furthermore, SD-WAN enhances cloud application performance by prioritizing vital business apps and allowing branches to interact directly with the Internet.
Reduces Costs
As businesses deploy a growing number of cloud-based services, the volume of data traveling across a WAN rises dramatically, driving up operational expenses. SD-WAN, thankfully, can minimize this cost by utilizing low-cost local Internet connectivity, offering direct cloud access, and lowering traffic via the backbone WAN. According to an IDC poll (prediction), over a quarter of survey respondents anticipate SD-WAN cost reductions of up to 39%, with the other two-thirds anticipating more modest savings of 5–19%.
Improves performance
Data transfer over a network isn't created equal. Fortunately, SD-WAN can be set up to prioritize business-critical traffic and real-time services such as Voice over Internet Protocol (VoIP) and then successfully guide it over the most efficient path. IT teams can help decrease packet loss and latency concerns by supporting important applications over dependable, high-performance connections, increasing employee productivity and morale. This is business-impacting performance.
Closing Note
Indeed, SD-WAN evolved and flourished in the data center over the first few years of development. However, the time has arrived to take it seriously as a tool for managing your wide area network. There are currently several vendors on the market, as well as several mature solutions to choose from. More significantly, the business cases for SD-WAN are expanding on a daily basis.

Data Center Networking
Article | August 10, 2022
There was a time when network security meant having servers on-site. A firewall would protect company data whenever internet traffic entered and exited the network. But, what about today? Modern businesses do not strictly function on-premise.
With the COVID-19 pandemic, the number of people working off-site part-time or full-time increased enormously – and suddenly. This change compelled cybersecurity professionals to reconsider their security measures. Their online privacy solutions had to ensure that their most precious asset — their data — was secure regardless of where workers accessed it.
Even when restrictions are lifted, businesses continue to use remote teams. As a result, more and more of a company's critical data and services are being housed in the cloud. These two criteria indicate that the need to examine network security on a regular basis is here to stay.
The good news is that a VPN, or virtual private network, is one of the most simple and widely accessible network security solutions for remote worker internet access.
Do VPNs Provide Reliable Business Security?
A virtual private network is a kind of Internet security service that enables users to connect to the internet as if they were on a private network. VPNs utilize encryption to provide a secure connection across vulnerable Internet infrastructure.
VPNs are one method for protecting business data and controlling user access to that data. The VPNs safeguard data as users interact with applications and websites through the Internet, and they can conceal specific resources. They are typically used for access control, although alternative identity and access management (IAM) systems can also assist with user access management.
VPN Encryption Enhances Network Security
Data is encrypted so that only authorized parties can view it. Anyone who manages to intercept it, whether a hacker, a fraudster, or another bad actor, is out of luck.
Imagine an employee is working from a coffeehouse, shared workspace, hotel, or airport and has access to your company's business-grade VPN. (Please keep in mind that business-or enterprise-grade VPNs are not the same as free VPN services.) The employee can create an encrypted connection between both the user's device and your VPN by using a VPN client installed on their preferred device and a public Wi-Fi network. This device, as well as any others that connect to your VPN, will establish encryption keys on both sides of the network connection. These keys will then encrypt and decrypt the information being exchanged.
The data of the person working at the coffeehouse is secured by the VPN after they create an encrypted VPN connection by utilizing the coffeehouse's Wi-Fi as a hotspot with a VPN client. Even if cybercriminals get access to the network of that coffeehouse, your employees and their data are secure within the VPN tunnel.
Closing Lines
Network security requires a VPN service from a trustworthy VPN provider. Our next-generation VPN enables enterprises to fully protect their assets in a dynamic, cost-effective, and scalable manner. A VPN solution enables you to connect private networks, devices, and servers quickly and simply to create a secure, virtualized, modern internet.
