I was providing consulting services to various Telco customers. It helped customers save on the cost of highly expensive MPLS links. With the help of Secure SD-WAN, they were able to utilize broadband or even LTE connectivity, which saves costs. That's the flexibility that Secure SD-WAN gives to various customers. In addition to saving costs, they are also able to utilize active-active load balancing, where you can have two parallel links: primary and secondary. The secondary one used to sit idle in traditional scenarios, whereas now, the solution gives you the flexibility to configure both links as active-active, so you can prioritize critical traffic from link one and other traffic from link two. At the same time, you also have the option to maintain redundancy.
Secure SD-WAN is a great way to manage your entire organization network, especially the WAN network. Customers don't have to hop to multiple places. Fortinet has a solution called FortiManager. With the help of that, you can monitor, configure, and maintain your entire organization's network. It's a very convenient option. It's a single pane of glass from a customer's point of view. They don't have to log in to individual devices, and they can see the real traffic. They can see what's coming into the network, what sort of alerts or logs are there, and what sort of applications are being consumed.
Secure SD-WAN doesn't help with tool consolidation, but it's a secure way or mechanism they provide so that if branch users are accessing the internet, they can directly break out from the branch location rather than coming back to the data center. In that way, it improves the user experience while also giving security at the highest level.
I have not interacted much with Secure SD-WAN in terms of API integration or third-party integrations. However, they have pretty good integration with the RADIUS, LDAP, and AD servers. In that way, they have everything in-built. You can make the firewall a DNS server or some sort of DHCP server. Such features are included there. From a security standpoint, they have open API integration with their own SIEM or SOAR solutions. Third-party API integration is also possible, but the API details that are exposed are very limited.
The integrated application protection provided by Secure SD-WAN is a cool feature. They have real-time scanning of the application with the help of SSL inspection. You get to see the real-time traffic of applications, and you can protect your network from harmful websites. They have a signature database for that. This data also gets refreshed. It's a direct feed that the device takes from the central intelligence.
When you have Secure SD-WAN in place, you are more secure from the outside internet. They have a flavor of SASE, but I have not worked on it.
When you have a granular view of your entire network including users and security features being enabled, you get more visibility into your network. You get to know what's coming in and going out. If an administrator sees that some traffic is being hit repetitively from a particular location, functionality is available to block a region, country, or even an IP or domain.
In terms of Secure SD-WAN reducing our mean time to resolve, in the case of issues specific to SD-WAN, I've seen instances where customers can look into the dashboard and inform the support team that this is the issue they are facing. This helps them to have some visibility into these firewalls and isolate the entire issue from the technology perspective; for example, when a wireless client is facing some sort of challenge accessing the internet, whereas some of the wired users are able to access the internet. The testing tools given in the FortiGate GUI dashboard come in handy during troubleshooting. With the very user-friendly interface, it becomes very obvious and easy for any IT guy to simply follow the workflow to resolve any day-to-day operational issues.
