SD-WAN simplifies the management and operation of a network and delivers several real-world business benefits.
FREMONT, CA: Organizations are increasingly adopting digital transformation to keep pace with emerging market trends, customer demands, and increased competition. But traditional network architectures weren’t built to manage the workloads and complexities of most digital transformation efforts. No wonder that network operations teams are turning to software-defined WAN (SD-WAN). SD-WAN benefits businesses by mitigating overhead costs and increasing network performance. This innovative technology simplifies the management and operation of a WAN and offers several real-world business benefits.

• Improves Performance
Not every network traffic is created equal. But, SD-WAN can be configured to prioritize business-critical traffic and real-time services and then effectively drive it over the most efficient route. By facilitating vital applications through reliable, high-performance connections, IT teams can reduce packet loss and latency issues, thereby enhancing employee productivity and improving staff morale. This is the performance with business impact.

• Boosts Security
Digital transformation is a double-edged sword. While it can enhance customer satisfaction and extend market reach, it can also expose a firm to significant security risks. That’s a concern, the increase in the frequency of cybersecurity events. Many SD-WAN solutions provide built-in security. However, the basic firewall and VPN functions offered by most SD-WAN solutions are often not enough, forcing IT teams to try and overlay security across dynamic SD-WAN connections after the fact. A better choice is to look for SD-WAN solutions that offer a wide range of integrated security features, like NGFW, IPS, encryption, AV, and sandboxing potentials, that can help prevent data loss and downtime, regulatory violations, and legal liabilities.
• Lowers Complexity
Digital transformation efforts can add layers of complexity to a network. The outcome is a risk of poor network performance and the need for locating onsite personnel at remote sites to manage the local IT infrastructure. SD-WAN can ease the IT burden by simplifying WAN infrastructure, utilizing broadband to off-load non-critical business apps, automating monitoring operations, and handling traffic through a centralized controller. An SD-WAN solution can be integrated into the local branch infrastructure to deepen security and management into the local LAN.
