An SD-WAN, or Software-defined Wide Area Network, allows businesses to control their network devices. This manner of virtual WAN architecture also provides a framework for data transmission over multiple connections, such as:
- MPLS systems
- Cellular connections
- Broadband internet circuits
Any organizations utilizing SD-WAN connections will enjoy secure connections throughout their choice of applications.
One of the primary features of SD-WAN connectivity is that it’s a network overlay that provides centralized control of all network devices. Because of this massive benefit, it’s believed that utilizing such a connection can drastically improve a company’s IT security.
Below, is a list of IT security-based benefits of SD-WAN:
Offsetting VP Problems
Companies used to build VPNs or DMVPs to ensure secure transport of their traffic when they were using the internet for transportation.
This methodology led to the following issues:
- An overabundance of VPNs that had to be managed. There was a necessity for firewalls at data centers. There was also a VPN device or firewall in the remote locations, so these VPNs could function.
- Seamless failover from a fiber-based type of transport is impossible. Companies are forced to strike some keys in between, making it arduous and costly to failover smoothly.
SD-WAN removes the need for firewalls for VPNs—nor do companies worry about VPN construction or traffic encryption. Such products have a controller and are a smart software-designed engine that constructs IPsec tunnels between locations when you plug in the device.
The controller builds VPNs automatically. Users only must provide an IP address or enable DHCP to let it pick an IP address from an adjacent server.
Mitigating Security-Disrupting Traffic
Companies without SD-WAN, and with a gig worth of bandwidth, frequently must run that entire gig through a firewall.
From there, the firewalls would split the traffic streams between the data center and the internet.
With SD-WAN, traffic is separated with a split tunnel, pushing half the traffic through the firewall before it reaches the internet. Then, the other half will travel site-to-site without undergoing any security measures.
The firewall only processes half of your gig, which is beneficial since security products are based on throughput and utilization. This reduces costs and streamlines management.
Security is Intuitive
SD-WAN empowers organizations to implement specific security features through the requisite platforms.
The most significant benefit of the above notion is cost reduction and making operations far less clunky and complicated in the security platform.
Several SD-WAN products include security features, meaning these devices take care of security on their own. Organizations using this technology don’t have to worry about deploying another firewall on top of that.
Also, other SD-WAN products allow companies to virtualize the firewall, removing the need for a physical firewall.
Furthermore, if a site doesn’t need overly comprehensive security, SD-WAN has some built-in capabilities that allow and deny specific sites and traffic.
The SD-WAN market gives many options to organizations to find inherent security measures that fit their given needs.
For these reasons and several more, SD-WAN is a drastic improvement for IT security. Reach out to VoxNet to learn more!
