Must-Have Features of SD-WAN to Consider

The companies focus on the underappreciated features of SD-WAN to secure locale LAN and secure direct connection to online resources. 

FREMONT, CA: A number of main SD-WAN characteristics are emerging, each more powerful and stable than the last one. The lives of IT teams are made simpler by improved efficiencies. Many of these automated characteristics, however, go unexplored. In some instances, when it comes to educating IT executives about the SD-WAN platform's full functionality, the vendor falls short.

Often, crises between security and networking teams prohibit the activation of such features by organizations. The popular one is a firewall of the next generation, which usually comes with an SD-WAN system. Many networking experts, of course, have their proven approaches and procedures.

Zero-touch Provisioning

The procedure for installing branch office networking equipment usually includes taking the physical equipment to a staging area. Technicians configure and evaluate it there and then deliver it to the branch. There, they are set up by a network expert. It takes a long time and several working hours for companies that distribute hundreds of SD-WAN units, often across several geographic locations.

A common feature of most SD-WAN devices is zero-touch provisioning. It configures a computer straight out of the box automatically. All they need is an internet connection to connect easily, reliably, and in a consistent way, and then auto-configure. It occurs through the use of predetermined models.

Encryption Key Rotation

On a daily basis, encryption keys need to be rotated, usually every 90 days. It is a repetitive manual process that requires defined procedures for change control and needs scheduled downtime. For organizations that work with the federal government in aerospace and defense, encryption keys are also important.

SD-WAN platforms substitute an automated framework for conventional, manual VPN key rotations. Developers can program this machine every minute to make rotations, and it will not disrupt the traffic of the data plane. As an outcome, there is better protection for the company, no downtime (as opposed to VPNs), and no requirement for manual resources.

Multiplexed VPNs

The reasonable choice would seem to be to buy several hardware sets when the business upgrades to SD-WAN. However, multiple virtual routing and forwarding (VRF) and VPN connections can be managed by SD-WAN technology, which can be multiplexed with one overlay. Prior VPN technologies could not handle these tasks.
