Wide-area networks (WANs) have long been used by businesses to provide multi-location business communications. Traditional WAN performance has failed to keep up with expanding bandwidth requirements as the adoption of cloud-based services, SaaS apps, and bring your own device rules has increased. Meanwhile, today’s digital organisations need not just flexibility but also seamless interoperability across users, apps, and devices, which most static WANs are unable to give.
Organisations have used software-defined wide-area network (SD-WAN) solutions that can adapt to the increased networking needs brought on by digital transformation as a result of considerations like these. SD-WAN improves application performance for highly-trafficked networks by providing more agility, responsiveness, and cost-effectiveness for commercial clients. SD-WAN may also provide complementary sets of integrated security technologies that both support and improve these new digital transformation requirements when correctly chosen and installed.
These are some of the capabilities:
- WAN bandwidth monitoring in real time
- WAN link remediation for unified communication apps
- For better management, overlay cloud orchestration.
- Reduced latency and improved performance by aggregating overlay bandwidth sharing over numerous connections.
- High-speed application recognition improves application performance and user experience.
- A comprehensive set of security solutions that provide total coverage of all connections and traffic.
How Do Companies Make Secure SD-WAN Work for Them?
SD-WAN is a low-cost alternative to WAN infrastructure that boosts branch speed and availability by using public network broadband. However, many IT executives struggle with the expense and complexity of building, installing, and maintaining an overlay solution when it comes to protecting SD-WAN. Because most SD-WAN providers offer little to no security as part of their solution, this occurs. As a result, clients must consider security as a last resort. And attempting to do so while dealing with large amounts of vital data is less than ideal, since fast changes in things like connection and application usage necessitate complete integration of security and networking at all times. SD-WANs must consequently include not just sophisticated security features like behavioural analytics and sandboxing, but also crucial features such as application security, intrusion prevention systems (IPS), and next-generation firewalls (NGFWs).
Single appliances that completely integrate all networking, communication, and security features into a single, coherent system will always be more efficient than separate systems that try to fulfil particular goals. This means that security must be implemented as an integrated feature, rather than an isolated overlay, to secure continuously changing network activities such as bandwidth sharing and connection fault repairs. Simultaneously, an integrated methodology ensures that performance is not harmed even while performing processor-intensive tasks like thorough analysis of complicated VPN connection overlays.
The Benefits of Secure SD-WAN
Customers’ networking and security concerns are addressed by deploying a strategically integrated solution that enables enterprises to experience a variety of benefits. Let’s take a closer look at each one:
Security at the highest level
Organisations may obtain comprehensive visibility across all of their company sites with an integrated security portfolio that includes powerful networking functions and a single-pane-of-glass view. Customers will be able to achieve their digital transformation goals without compromising security by adopting enterprise-grade security with integrated networking functions, complete SSL inspection, and dynamic VPN tunnelling at branch sites.
Management that is centralised
Enterprise users may benefit from zero-touch provisioning and centralised administration capabilities across the full SD-WAN deployment, from configurations to connection to security, with an integrated SD-WAN solution in place. IT teams may assure automated control of branch office WAN connectivity by managing and orchestrating a single security solution across numerous branch locations, cloud environments, and devices. Customers will also have single-pane-of-glass visibility throughout their distributed businesses, encompassing all users and apps, in order to detect possible risks.
Savings on expenditures
Most businesses want to be as cost-effective as possible. This may be accomplished by substituting high-bandwidth, low-cost broadband connections for low-bandwidth, high-cost WANs. IT teams may design and automate site-to-site VPNs that form a mesh linked overlay across branch offices, the cloud, and corporate data centres using an integrated solution. They may also offer uniform, policy-based enforcement and protection across the dispersed network, inspecting traffic between offices as well as all application traffic in real time — a beneficial trend away from isolated security procedures.
Complexity is reduced.
Organisations will avoid the complexity commonly involved with WAN administration, configuration, and orchestration when security and networking are controlled through a single interface. This single-pane-of-glass perspective will not only increase control and visibility, but it will also cut down on the time it takes to deploy leased lines and MPLS, as well as establish an effective security policy. Customers will be able to solve problems more rapidly since locations are recognised more immediately.
According to one study, enterprises that employ SD-WAN consume 50% more bandwidth than those that rely on standard WAN connections. This bandwidth allows for more effective application accessibility, more robust workflow assistance, and increased productivity, giving these businesses a significant competitive advantage. Customers may flexibly expand broadband capacity depending on their unique requirements using sophisticated networking capability with an integrated SD-WAN solution as their bandwidth needs develop. Customers can check all the boxes for high-application performance using this method, without risking security vulnerabilities or having to play catch-up to secure their networks.
Conclusions on Secure SD-WAN
Secure SD-WAN features allow your clients to do far more than a typical SD-WAN solution. Secure SD-WAN benefits give customers direct access to business branches while lowering WAN expenses, allowing them to simplify their infrastructures and improve performance. Enterprise clients can simply control internet connectivity and performance while avoiding the costs of adopting separate security solutions as an overlay for an unsecured SD-WAN by utilising an integrated Secure SD-WAN solution.
