SD-WAN enables business-critical cloud apps, core networks, and internet-based services to be accessed quickly and easily. It accomplishes this by routing traffic across one or more WAN links, depending on network conditions.
FREMONT, CA: SD-WAN was created to enable digital innovation. SD-WAN solutions allow high-speed application performance at the WAN edge of branch locations by leveraging both the corporate WAN and multi-cloud connections, enhancing and transforming an organization's capacity to connect, do business, and respond to customer needs. SD-WAN enables business-critical cloud apps, core networks, and internet-based services to be accessed quickly and easily. It accomplishes this by routing traffic across one or more WAN links, depending on network conditions. It then keeps an eye on those connections and makes changes as needed to maintain constant performance.

Applying SD-WAN Security Measures
Several characteristics distinguish SD-WAN and Secure SD-WAN. Organizations may better select an SD-WAN solution that provides greater performance while simultaneously addressing the risks linked with WAN security and the costs and constraints of trying to build an overlay security solution after the fact by prioritizing the following functions. The following areas should be prioritized:
Consistent Enforcement of Policies
By depending on an overlay solution, organizations who are late in adopting a security strategy for their SD-WAN solution may struggle to maintain consistent policy enforcement across their interconnected ecosystems, including their multi-cloud applications. SD-WAN solutions solve this problem by combining single-pane-of-glass management with zero-touch deployment, making the process of implementing security measures much easier.
It also easily interoperates with other Fortinet solutions deployed across the distributed network for a universally implemented and controlled security framework, whether on-premises, on distant devices, or in the cloud. Organizations should search for an option like this when installing an SD-WAN solution to effectively manage digital transformation risks.
Next-Generation Firewall (NGFW) Functionality
Many organizations believe that to obtain the level of performance required to assure business continuity, they must sacrifice on cost and security when it comes to SD-WAN. However, choosing a solution that cannot analyze traffic at network speeds, protect against a wide range of external threats, or separate and disarm live threats will only lead to disastrous outcomes—especially given that most security teams are already overworked due to the rising cybersecurity skills gap.
Organizations can enjoy SD-WAN and Next-Generation Firewall (NGFW) capability on a single appliance with secure SD-WAN software, lowering overall complexity and Total Cost of Ownership (TCO). Furthermore, this service frees up security teams' time to focus on more important activities like the analysis by including advanced capabilities like anti-malware, web filtering, sandboxing, and IPS inspection.
