    It's great for connectivity. I think if you're looking at. There's a lot of players out there that do SD- WAN, you can do hosted solutions, you can do your own. If you're looking to do it yourself, I think this product works out well. I do know it's hosted elsewhere by some other companies, but for us, we want the control and we don't have a huge amount of sites, so being able to control that's important and the data that we can get out of the product, we can see just seeing the application experience through Cisco Catalyst SD-WAN, really gives us good information.

    Fortinet FortiGate addressed an immediate security issue we had a few years ago. The device gave us a much clearer picture of the activities on our network and also more importantly, increased our awareness of threats from the internet as a whole. Fortinet FortiGate helps us to mitigate these threats with regular signature updates from Fortiguard labs, identifying certain characteristics which, once recognised by Fortinet FortiGate, can be harnessed to deploy powerful 'playbooks'.

    This is well suited when you need to deploy a virtual router to provide SD-WAN services across multiple sites. This works great for small businesses since they added firewall services. The price and feature set are also great for mid-sized enterprises due to the ability to manage multiple appliances with templates, central reporting, and ability to provide high availability of the appliances with VRRP.

    Pros
    Cisco
    • We are able to use a multiple different circuits to go into the cloud, so we are not relying on just one particular private wireless. We're relying on wine circuits, ethernet, ethernet out. So it provides us that flexibility where we didn't have that before. Provides security that is very robust and flexible and scalable and it provides us with, the biggest thing is redundancy, where we have backup. For example, we have a Starlink for nuclear power plants. If our main circuits go down, we have that. And without Cisco Catalyst SD-WAN it would be very hard to actually achieve, to accomplish true redundancy. So we're happy with Cisco Catalyst SD-WAN in that regard.

    • SD-WAN - Load balancing of Internet traffic is a USP of Fortigate and makes it stand tall in the competition. Be it 3 or more Internet Links, multiple Subnets/segments of users to distribute and bandwidth load balancing for links and users. SLA based monitoring of Internet Links / MPLS links, makes it even better to choose the links on the basis of performance (Latency, packet loss, Jitter etc).
    • SSL VPN configuration - As we all have WFH force (to some extend or all employee) during Covid-19, it is impossible to plan BCP without having a SSL VPN. In Fortigate, the SSL VPN configuration is very easy with the help of wizard. The deep CLI-level debugging is also very helpful in troubleshooting. Type of tunnel can be easily configured - Full Tunnel or Split Tunnel for SSL.
    • Explicit Proxy - This is also a great feature to shape and re-route the traffic, configuring the Proxy on the Firewall itself. We are using this feature in Pilot for now, and planned to rollout in few weeks looking at the success rate of the POC.

    Cons
    Cisco
    • I will say the way we use it now, and I think what happened was the way it was deployed, it was fine, but unfortunately over the course of the years we've gotten a little out of hand with our device templates and feature templates. I think if there's any form of feedback that I would give to Cisco is how do we find ways to improve the environment as it stands so we get to a certain point with the environment and then we don't know how to undo it or fix it or optimize the environment. Because right now we're in a position where we're playing a lot of catch up and clean up and if there was a way or some tool or feature that we can take advantage of that would allow us to optimize that environment where we will kind of corner ourselves into a lot of problems in the future. There's some feature or something that we could take advantage of that will allow us to optimize that environment and not let it get out of control pretty easily. That would be my suggestion.

    I would rate SD-WAN highly because it has significantly improved network performance, reliability, and cost-efficiency for my organization. Its ability to optimize traffic dynamically, enhance security, and simplify management across multiple locations has been invaluable. With SD-WAN, we’ve reduced dependency on costly MPLS, improved cloud application performance, and gained greater control over our network infrastructure.

    The niche configurations are given equal focus as the standard use cases, which can make onboarding difficult in the beginning (ie why am I not using an entire tab of the portal), but aside from that part, the dashboard is relatively easy to navigate and apply the configuration. The metrics and analytics available are also nice to have in a single pane.

    The firewall runs very well, firmware updates are fairly quick but you must follow the upgrade path. Neglecting this step will cause a lot of pain. If you decide to go with Fortinet FortiGate switches and/or access points, they can be managed within the firewall which is great. We're also using the FortiAnalyzer which easily plugs into the firewall for any reporting you may require.

    The Support team at Fortinet is excellent. They can not only help you configure the device for what you are trying to do, they offer suggestions on improving rules, and troubleshooting issues. Their response time is fast, ensuring you are up and running immediately with no questions asked. We had a hard drive failure in one of our Fortinet Fortigate appliances. The tech answered immediately, and started rebuilding the drive after some preliminary investigations. After rebuilding, there were still errors and issues, so they dispatched a brand new Fortinet Fortigate appliance. The tech then backed up the configurations for when the new device came in, which showed up in a few hours. A restore of the configuration took less than a minute, and there were no more errors or issues.

    We currently have almost all Cisco Meraki and would have loved to keep the product portfolio the same. Silver Peak was far cheaper and offered far more features. A lot of our evaluation showed that NGFW offers SD-WAN but it is not a full-featured deployment. Silver Peak is by and large better at being able to use both links at once, offer failover, QoS, and central reporting.

    • The pricing given to us for our firewall was well within what we were already spending for other vendors solutions and had the added value of eliminating a separate expense for a dedicated web filtering appliance.
    • We have also adopted Fortinet's security fabric approach and thus changed vendors for our switch and AP devices. These devices have come at reduced prices as compared to another previous vendor we were using, particularly in relation to ongoing annual maintenance costs.
