How to Secure Your Network With Cloud-Based SD-WAN?


Security is an essential aspect of SD Wan and cloud-based SD-WAN. Fortunately, there are several ways to protect your network from threats that may arise using SD-WAN technology. To encapsulate the SD-WAN definition, it enables businesses to use any number of transport services to safely connect users to applications. Listed below are some of the most common approaches to security. 

Cloud-Based SD-WAN

SD-WAN provides a powerful combination of network security and traffic prioritization. The combination can ease congestion, boost application performance, and cut networking costs. Traffic prioritization allows network administrators to prioritize traffic to locations most important to the company. For instance, if a sales call is taking place over videoconferencing, traffic from other branches won’t affect that call. Meanwhile, less-important traffic can be deprioritized.

SD-WAN can be deployed as a standalone solution or through a local ISP. However, it is essential to incorporate security capabilities into the solution. 


Ensure that all your data and traffic are protected with SD-WAN encryption. With today’s increasingly sensitive data, security is of the utmost importance. For this reason, businesses must implement robust security measures and regularly rotate their encryption keys. But these operations are disruptive and require downtime. Fortunately, SD-WAN encryption provides a simple and automatic solution to this problem.

SD-WAN encryption ensures that data transmission is secure, even when users in different locations communicate over the same network. It also ensures that voice and data traffic is prioritized based on payloads. This way, an SD-WAN won’t disrupt a voice call between two sites. In addition to this, SD-WAN maintains application performance.

Next-Generation firewall

The next-generation SD Wan firewall (NGFW) is a new kind of firewall that combines advanced security capabilities with application awareness. This technology uses deep packet inspection to determine applications and control access regardless of IP port. These firewalls are available from traditional security companies and SD-WAN vendors.

The next-generation SD-WAN firewall can help organizations reduce the number of network devices and streamline network management. It also provides advanced threat protection and enforces security policies across branch offices. In addition, compared to traditional router-based environments, this technology combines WAN optimization and routing in one appliance. This reduces IT complexity and increases IT efficiency by consolidating network management into a single console.

 Identity-Driven Policies

Identity-driven policies for SD-WAN make it easy for IT organizations to track network resources usage, thereby making it easier to manage network resources. Using an identity-driven policy to manage SD-WAN traffic makes it easier to set up tailored policies to each user’s location, application, or network interface.

Identity-driven policies help SD-WAN administrators adhere to business goals, while application-driven policies can optimize traffic steering across the WAN. Application-driven policies can provide context-based service routing and can be tailored to individual users. They can also provide real-time monitoring of traffic flows. Identity-driven policies also enable administrators to implement dynamic decisions regarding traffic routing across the WAN.

Identity-driven policies for SD-WAN can also help security teams implement least-privilege access policies. These policies apply to users, devices, and groups and set appropriate application access levels. 


Virtualization of SD-WAN and security can greatly benefit organizations with multiple branch locations. It reduces hardware costs and simplifies security management, increasing flexibility across the entire organization. 

SD-WAN and security integration are growing in maturity and adoption. Most enterprises view the reduction of the number of hardware appliances as a positive development, reducing hardware maintenance costs and potential failure points. SD-WAN devices are also becoming more secure, incorporating NFV and Service Chaining into the solution.


In the end, according to the Hippo Adviser studies SD-WAN is an emerging technology designed to help organizations better manage their network services and infrastructure costs. By automating networking services, SD-WAN can help enterprises manage applications and reduce the total cost of ownership. This technology automatically routes traffic across the most cost-efficient WAN path.
