SD-WAN Offers Answers to Network Security Problems

SD-WAN answers many of the challenges posed by security that demands a higher focus on networks.Enterprises often take a layered approach to security, deploying solutions for network, compute and application. With so many solutions increasingly being network-centered, such as Internet of Things components and cloud technology, many organizations are recognizing the need for a network-focused security strategy. In many cases, software-defined wide area network (SD-WAN) is able to address the challenges of network security.

Networks are the area to which there’s been the most change in recent years, so it makes sense that security is more advanced in this realm. Here are five recommendations for implementing secure SD-WAN:

  1. Add encryption to your WAN transport. When they choose SD-WAN, companies have access to low-cost broadband and can encrypt all Internet flow to each site without the need for administrators to make manual configuration changes to routers after each change to the network. It’s also important to note that SD-WAN is more secure than most private IP services because there can’t be a breach to the data even if the carrier network is threatened.
  2. Make sure your cloud connection is secure. It doesn’t matter how secure your client’s public cloud service is, whether they’re accessing Amazon or Salesforce. Every time they transfer sensitive data over the Internet to get to the cloud service, it’s an opportunity for a security breach. The SD-WAN provider may offer granular Internet breakout so that your client can distinguish between security mandates to move traffic through particular secure gateways. They’ll also have next-generation firewalls stationed at your branch or in the cloud or data storage center. All of the inherent risks associated with cloud solutions is mitigated by SD-WAN.
  3. Cover local branch security. Each of your client’s branch offices will require security, especially in cases where there is direct Internet access. The cost of buying and configuring physical appliances for each site can be prohibitive, and this method requires an engineer to travel to each site. SD-WAN allows your client to deploy VPNs, firewalls or WAN optimization from a central location by using network functions virtualization. This makes it convenient to provide security coverage for each branch location.
  4. Meeting requirements for compliance. The rules governing healthcare and financial services, including HIPAA or PCI data security fit perfectly with SD-WAN technology. SD-WAN allows the enterprise to create virtual overlays to segment applications traffic.
  5. Create secure segmentation. Segmentation allows the IT team to isolate applications traffic for security purposes or to work with specific performance requirements. While legacy networks could do this, it was time-consuming and challenging. Segmentation with SD-WAN allows for consistency of configurations and best practices defined and enforced through business intent policies.

With security becoming a growing IT cost, MicroCorp anticipates more customers selecting an SD-WAN technology to create a secure and manageable cloud-based environment. As the demand for more agile, cloud-based WAN-technologies accelerates, we continue to provide focus to the variety of WAN technologies available.
