Businesses have traditionally used wide-area networks (WANs) to facilitate communications among multiple locations. Traditional WAN performance can’t keep up with the expanding bandwidth demands of cloud-based services, SaaS apps, and BYOD rules. Most static WANs can’t provide the seamless interoperability that digital companies need across people, apps, and devices.
Because of these circumstances, organisations are utilising SD-WAN solutions to adapt to the rising networking needs of digital transformation. By improving clients’ agility, responsiveness, and cost-effectiveness. SD-WAN may offer complementary sets of integrated security solutions that support and promote digital transformation.
Some of the skills include:
- Real-time WAN bandwidth monitoring
- Remediation of WAN links for unified communication applications
- Cloud orchestration should be overlaid for better administration.
- Encoding overlay bandwidth sharing over several connections reduced latency and enhanced performance.
- Fast application recognition enhances user experience and application performance.
- A broad range of security options offers complete protection for all links and communications.
How Can Businesses Use Secure SD-WAN to Their Advantage?
Using public network bandwidth, SD-WAN, a low-cost replacement for WAN infrastructure, increases branch speed and availability. However, when it comes to safeguarding SD-WAN, many IT administrators struggle with the cost and difficulty of developing, implementing, and maintaining an overlay solution. This happens because few SD-WAN providers include security as a feature in their offering. Clients must, therefore, only use security as a last resort. Trying to do so with a lot of necessary data isn’t optimal because of quick changes in connection and programme usage. SD-WANs must include application security, intrusion prevention systems (IPS), and next-generation firewalls, as well as sophisticated security features like behavioural analytics and sandboxing (NGFWs).
It’s better to utilise a single appliance that integrates networking, communication, and security than many systems with distinct goals. To protect continually evolving network functions like bandwidth sharing and connection fault fixes, security must be implement as an integrated element. Parallel analysis of complex VPN connection overlays is a processor-intensive activity protected from performance degradation by an integrated technique.
What Secure SD-WAN Offers
Implementing a strategically integrated solution addresses customers’ networking and security issues, allowing organisations to gain several advantages. Let’s examine each one in more detail:
Highest level of security
An integrated security portfolio with strong networking capabilities and a single point of view can give visibility across all corporate sites. Customers can achieve digital transformation without compromising security by deploying enterprise-grade security with integrated networking, SSL inspection, and dynamic VPN tunnelling at branch locations.
A centralised management system
With an integrated SD-WAN solution, enterprise customers may profit from zero-touch provisioning and centralised management capabilities across the whole SD-WAN deployment, from configurations to connectivity to security. IT professionals can ensure automated control of branch office WAN connectivity by monitoring and coordinating a single security solution across various branch locations, cloud environments, and devices. To identify potential hazards, customers will also have single-pane-of-glass visibility across all users and apps in their distributed organisations.
Savings on expenditures
The majority of businesses want to be as economical as possible. This can be done by switching out low-bandwidth, high-cost WANs for high-bandwidth, low-cost broadband connections. Using an integrated solution, IT professionals can design and automate site-to-site VPNs that mesh branch offices, the cloud, and corporate data centres. They may also provide uniform, policy-based enforcement and protection across the distributed network, monitoring all application traffic in real-time and traffic between offices.
Complexity is reducing.
When security and networking are managed through a single interface, organisations may avoid the complexity associated with WAN administration, setup, and orchestration. This “single-pane-of-glass” approach will speed up the deployment of leased lines and MPLS, create an efficient security strategy, and improve control and visibility. Since locations are recognised more quickly, customers will be able to solve issues more quickly.
Improved effectiveness
One study found that businesses using SD-WAN use 50% more bandwidth than traditional WAN connections. This bandwidth boosts productivity, workflow support, and application accessibility, giving these companies a competitive edge. Using sophisticated networking technologies with an SD-WAN solution, customers may swiftly increase internet capacity as bandwidth needs vary. Customers can obtain high application performance without risking security issues or playing network security catch-up.
Summary of Secure SD-WAN
Your clients may accomplish far more with secure SD-WAN capabilities than with a standard SD-WAN solution. Customers may directly connect corporate branches thanks to secure SD-WAN advantages, reducing WAN costs, simplifying infrastructures, and boosting performance. By using an integrated Secure SD-WAN solution, enterprise clients can easily monitor internet connectivity and performance without spending money on additional security solutions for an unsecured SD-WAN.
