With Security-as-a-Service (SECaaS), SD-WAN providers can integrate security into their offering.
Not only does a cloud-based security stack provide a complete set of security features, security policy can also be easily configured and managed via a single orchestrator. Enterprises gain control over the security services as they add new links to the WAN.
There will no longer be any need for third-party security appliances, managing it through another service provider or installing additional software or virtual network function (VNF).
The SD-WAN deployment can be scaled more efficiently and securely in this manner with centralised security control across the entire WAN.

Must-have SD-WAN security features
Some of the most important security features in SD-WAN include next generation firewall, unified threat management (UTM) and intrusion detection and prevention systems (IDPS).
These security services ensure that the enterprise is able to control, limit or block certain access to minimise the risk of network-based exploit attacks and malware. It should also be able to detect and stop worms, trojans and other malicious threats.
Considering how SD-WAN is rapidly enhancing the traditional WAN, security needs to become an integral feature in the overall offering. With an integrated cloud-based security stack, enterprises can connect their data centres, branch offices and the public clouds with a peace of mind.
