Software-Defined WAN (SD-WAN) is one of the most rapidly adopted technologies of the past decade. According to a recent study published by Dell’Oro Group, the worldwide sales of SD-WAN technologies are forecasted to grow at double-digit rates over each of the next five years to surpass $3.2 billion in 2024. This growth is certainly a testament to some of the more well-known benefits of SD-WAN technology, such as centralized network policy management, network flexibility and application-aware routing. But we should not overlook how some of these same features can be optimized to boost network security, nor lose sight of the new security considerations that SD-WAN introduces.
With SD-WAN, branch offices are now part of an enterprise’s network topology, with their own Internet egress. Corporate devices can access the Internet via multiple endpoints, adding a layer of complexity to network security. However, if properly configured, SD-WAN can simplify management, help improve security, and decrease threat vectors. In total, SD-WAN greatly improves an organization’s security posture and can ultimately decrease the stress and costs associated with a security intrusion.
In this article, we will review how to optimize your SD-WAN to its full potential for advanced security protection from threats.
