As the modern workforce becomes increasingly mobile and enterprises branch out as they grow their organization, Software-Defined Wide Area Networks (SD-WAN) have become a popular choice in the evolution of networking. By applying the benefits of software-defined networking (SDN) to traditional router-centric, hardware-based networks, SD-WAN offers enterprises improved flexibility, scalability, performance and agility.
However, with all the benefits SD-WAN provides organizations, it also opens the door for a new set of security challenges. In this article, we'll discuss how you can shut the door on those threats and use your SD-WAN to its full potential.
Issues with SD-WAN security
SD-WAN enables users in branch offices to remotely connect to an enterprise's network through a large web of connected devices over the internet. This IT sprawl and surplus of endpoints adds a layer of complexity to network security. Even one unsecured entry point could lead to a critical security breach.
While most SD-WAN offerings come with out-of-the-box security features, they should not be used as standalone solutions to securing your network. In order to determine what security features you need to add to your network, you first need to understand what features are included with your SD-WAN solution. If you don't have the knowledge of what is secure and what's not, it's easy to leave your system exposed.
Built-in SD-WAN security features
Most SD-WAN solutions only offer a few built-in features that can provide a base for network security. While they don't make up a comprehensive security solution, they are vital for mitigating risk.
