SD-WAN Security Options in Different Networking Architectures

With disruptive innovations and key considerations such as cloud computing and security, legacy networking architectures are falling behind. Old models like hub and spoke are not optimized to support modern applications, and have contributed to the rise of companies deploying SD-WAN as an alternative. With the growing popularity of SD-WAN comes a number of newer architectures better suited for modern enterprise environments.

Apcela recently released a guide discussing how SD-WAN operates in five different networking architectures based on security deployment options. Read a quick review of these five architectures below:

1. Single data center with centralized security

Features an infrastructure similar to hub-and-spoke that backhauls traffic to a centralized data center. Is easy to manage, but also has downsides – such as poor network performance and latency. SD-WAN can help to optimize this traffic.

2. Distributed security at the edge

Deploying firewalls at branch locations means traffic doesn’t have to be routed back to a central data center, which improves traffic latency and performance. SD-WAN overlay can introduce split-tunneling to lessen security costs.

3. Regionalized security

Deploying security firewalls at regional hubs instead of at centralized data centers is cheaper and still provides good security even at the edge, but could benefit from the whole SD-WAN stack.

4. Cloud-based security

This modern approach has very little infrastructure, allowing for easier management but sacrificing latency. Integrating SD-WAN can allow companies to reap the benefits of the architecture without sacrificing performance.

5. At the edge: Software-defined security

The newest and most integrated option incorporates SD-WAN on a virtual level. It allows for a good balance of security and management ease.

SD-WAN can radically change an organization’s environment for the better, and allows for a multitude of security options. Find out which architecture works best for your security and network needs as well as your budget. To learn more, click here.
