FREMONT, CA: As remote work grows more prevalent and employees connect from outside the corporate network, it is critical to have reliable and secure access.

This can be a challenge for enterprises, mainly when devices become increasingly scattered across numerous locations. Cloud-based services, applications, and platforms complicate matters further, as employee networks may struggle to match the required flexibility, scalability, and speed of implementation.

SD-WAN, a virtual overlay solution for an existing WAN, is one solution to these difficulties. SD-WAN provides a comprehensive solution by connecting Software-Defined Networking (SDN) with fixed and mobile transport networks.

SD-WAN infuses the network with intelligence, provides real-time monitoring and management of network traffic, and maybe a more cost-effective alternative to traditional networking. It enables an organization to react swiftly to environmental changes and external threats.

The following are five critical security benefits of SD-WAN:

Centralized and scalable security

SD-centralized WAN's controller can define security policies that apply to the entire network. The company may design and disseminate security policies that can then be centrally enforced and managed.

The centralized controller enables companies to filter and prevent harmful traffic without interfering with the regular operation of the network. Suspicious behavior can be routed and reported to administrators automatically.

The company can define, control, and implement security rules on a large scale in response to company changes and growth and the provisioning of new applications.

Prioritization of traffic from remote areas

SD-WAN can prioritize traffic from locations by routing phone or video traffic via low-latency, high-bandwidth connections (such as MPLS) and using less expensive local internet for less time-sensitive traffic.

The organization can create a WAN by combining network connection types, including private circuits, mobile networks, and any internet connection. This helps companies to verify if the connectivity used is suitable for the data being transmitted.

Touchless operation and segmentation

Zero-touch provisioning enables companies to bring a new branch or distant site online quickly. Human error is reduced since once a policy is developed or modified, it is immediately delivered to all devices connected to the SD-WAN.

They can create policies governing which programs a workplace may use, such as the CRM system, cloud-based applications like Office 365, or real-time traffic such as VoIP. From a single pane of glass, they can manage segmentation policies that adjust dynamically to network changes.

Encryption of traffic and firewalls

SD-WAN secures traffic between locations by linking them all through a secure tunnel protected by robust encryption.

Companies can deploy virtual firewalls in real-time to cope with harmful threats or viruses and then disable them once the threat has been neutralized. Additionally, they can utilize virtual firewalls to restrict remote employees' and guests' access to websites.

Cloud connectivity

SD-WAN enables direct connectivity to cloud providers and endpoints seamlessly and securely, optimizing the cloud experience. It provides the organization with a high level of protection, preventing data loss due to unauthorized breaches.
