What are the security capabilities of SD-WAN

Tags: Cloud

Nowadays SD-WAN is a quintessential component in transmitting and accessing data remotely. But for anyone, the deep-lying doubt is how secure the data/ connection?

Security capabilities of SD-WAN

A number of SD-WAN implementations provide a better way to encrypt your branch-to-branch corporate traffic using IPsec. IPsec protects the data in transit. SD-WAN uses a centralized control function to securely and accurately direct traffic across WAN due to which there is an increase in application performance which results in enhanced user experience, increased business productivity, and reduced costs for IT.
But the cost, complexity, and interoperability issues associated with existing network components are some of the weaknesses of SD-WAN that need to be considered.

Thank you for sharing the info.
What you have said makes sense. I have learned through experts that SD-WAN implementation offers a way to encrypt branch to branch transit, using IPsec. Also, some are saying that we have to station additional devices at the branch-office premises and the cloud head-end to create an IPsec VPN overlay. Will it add more cost burden on organizations?

Even though, these could be sited as expenses in the long run SD-WAN implementation could prove to be an advantage. A major benefit of SD-WAN over traditional WAN is the level of visibility into the network. Network administrators can manage and orchestrate the network centrally, and monitor traffic for deviations. However, the degree of visibility may vary depending on the vendor.

I have also learned that NGFW is a key element of SD-WAN security. Next-Generation FireWall is deployed at the branches as well as headquarters. An NGFW is a virtualized and improved version of traditional hardware-based firewalls.
