What is our primary use case?
I used this solution while working with my last organization. I handled plain firewall deployment as well as SD-WAN deployment.
How has it helped my organization?
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.
What is most valuable?
The security features that they have are quite good. On top of that, their licensing model is quite nice where they don't charge you anything for the SD-WAN functionality for the firewall. The routing and firewall features are also good.
The unified view that they have built into this firewall is good. Within the same dashboard, you get to see the security profiles, the type of traffic that's passing through, the top applications that are being consumed, etc.
It's also very easy to use.
What needs improvement?
I was not looking after the operations part, but sometimes, I did get engaged in some critical activities related to operations. There are some caveats in every product. Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem. There were tunnel issues where there was already established connectivity, but at the kernel level, there were some issues. For example, there's a feature for auto-site connectivity wherein whenever it automatically creates a new tunnel, at the kernel level, it also creates an interface. Sometimes, that interface crashes and a new interface could not be created, which results in connectivity loss.
Fortinet has established itself in the SMB market segment. It's doing pretty well in that space, but when it comes to the enterprise segment, they are lagging a little bit. It all boils down to the performance of the hardware. If I enable all of the security features available on my device, the throughput degrades quite a lot. If I have put 10 GBPS of throughput on a firewall and I enable all of these features available, such as IPS or UTM functionalities, the throughput comes down to 1 GBPS.
For how long have I used the solution?
I used Fortinet FortiGate for seven months. I last used it in February of this year.
What do I think about the stability of the solution?
I'd rate it a seven out of ten in terms of stability.
What do I think about the scalability of the solution?
The solution offers the option of deploying VMs or virtual machines to any public cloud, such as AWS or Azure. It provides such flexibility. If you have any application hosted in the cloud space, you can have a VM spin of the FortiGate over there and have a site-to-site tunnel established, so the scalability is there. Otherwise, at the site level, it's mostly hardware-based work. If you size it properly, then you have the option to expand. You might have chosen a low-end model because of the tight budget. In that case, it's not scalable on a specific site. However, if you have a certain number of sites, for example, if you have 400 of them and you want to expand to 500 or 1,000, there is simply a license that goes at the FortiManager level to support additional devices. FortiManager provides a single pane of management.
I'd rate it a seven out of ten in terms of scalability.
How are customer service and support?
My experience was not that rewarding. It took me around three hours in total to get a simple issue identified and fixed. I escalated it to their L3 engineer, and after that, I was able to resolve the issue. The entire process took around three hours. First, their initial level person was troubleshooting, then it went to the next level, and then it went to the highest level.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
From the security perspective, I have not used any other solution, but I did have a glance at Cisco's portfolio. Cisco Meraki is one of the solutions that you can compare it with. Others were more specific to the routing and switching domain. I know the concepts and theory of Cisco SD-WAN, but I have not used it in a real environment for any customer.
How was the initial setup?
For one of the clients, it was deployed on the Azure public cloud. Initially, it was not easy. It was complex. Every product and technology requires a certain type of prerequisite, and when you have anything hosted on a public cloud, it becomes a tedious job to get things done quickly because multiple stakeholders are involved in that.
I have deployed Secure SD-WAN specifically for many customers. I find it easy, but you need one person to be at the site for remote connectivity. That person just needs to do the basic configuration. Once the device has IP reachability, you can easily discover it from FortiManager, which is the central controller. So, once you have the device on FortiManager, it takes a few clicks to onboard the device because you already would have a template in place.
The deployment duration depends on the number of sites. For a customer with ten sites, it would take a week's time because there are a lot of dependencies. It also depends on the customer's readiness and availability, but a week's time would be enough for the deployment of ten sites. If there is proper planning in place, you can also deploy 50 sites in a week, but that's something you cannot control from your side because there are a lot of dependencies on the customer and the service provider. If you have to integrate it into a customer's existing network, it becomes quite challenging to make them understand your prerequisites. There are instances where nobody is available from the customer side from the technical standpoint to help you. Those are the roadblocks, but from the solution perspective, it's quite easy to onboard devices.
What about the implementation team?
The deployment can be done by one person if that person is dedicated to a single project, but if more projects are running in parallel, you would require a few more people.
It does require maintenance, which includes upgrading the operating system and installing patches. Two to three people would be enough for around 500 site maintenance but not in the 24/7 case. If it's 24/7, then nine people would be required for that.
What's my experience with pricing, setup cost, and licensing?
By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic.
What other advice do I have?
To those evaluating this solution, I'd advise doing a PoC of different vendors who are meeting their requirements. They can then decide for themselves after seeing the demo.
Overall, I'd rate it an eight out of ten. It's user-friendly. It's also good features-wise, but their support is weak, and on the architecture front, it's not true SD-WAN. It's not decoupling the control chain functionality from the device to the controller.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
