What do I think about the stability of the solution?

The solution is stable. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

It's scalable. The model we bought is highly scalable. However, if you buy a device on the low end, it may not be scalable. You need to consider what you need in advance and buy more than you need if you believe you will need to scale. 

How are customer service and support?

Technical support is okay. Compared to Palo Alto, they need to improve a bit. Palo Alto is better. The first-level team isn't very knowledgeable. 

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

I work with Palo Alto, Cisco, Fortinet, et cetera.

How was the initial setup?

The initial setup is very simple and straightforward. It's not overly complex or difficult. You only need one person to implement the solution. 

The deployment will take only one hour, however, the policy web creation based on the user requirements may take time. That is the nature of every firewall. Usually, the deployment takes only one to two hours.

What about the implementation team?

We handled the setup in-house. We didn't need any outside assistance. 

What's my experience with pricing, setup cost, and licensing?

I don't directly deal with licensing. I can't speak to the exact costs.

What other advice do I have?

I'm an end-user. I used to be a partner. 

We're using the latest version of the solution and update regularly.

I'd rate the solution seven out of ten. 

Which deployment model are you using for this solution?

A next-generation operating system and firewall with a lot of features
Pros and Cons
  • "I am satisfied with Fortinet FortiOS. It's a cool product and has a lot of UTM features. It has application control, web filtering, antivirus, IPS/IDS, DNS filtering, and many things in that firewall. It also has a web application firewall WAF feature. On the feature side, it's a good firewall."
  • "It would be better if AWS instances were available. If I want to upgrade from T2.small to T2.medium, it should be available rather than having a big instance and paying a lot of money for that. The issue is that we had deployed in AWS Cloud, and we were using a very small instance. Recently we wanted to move in-house and deploy it on the big instance because it was struggling with the RAM. If we use T2.small, we cannot upgrade it to the T2.medium. It has predefined instances in the marketplace with a lot of cost differences. If I can increase the RAM, I have to choose the T3.large instance. If I'm paying $270 for the small instance, I have to pay more than double the cost for T3.large. It is about $850, and this is not good. So, it would be better if it was cheaper. I think both AWS and Fortinet should think about that. They should provide it on lower instances as well. If I want to upgrade it from T2.small to T2.medium, it should be available, but it's a problem."

What is our primary use case?

We use Fortinet FortiOS to protect our office, and we have another deployment in production. We have the PCI DSS environment on which we have deployed the Fortinet Firewall.

What is most valuable?

I am satisfied with Fortinet FortiOS. It's a cool product and has a lot of UTM features. It has application control, web filtering, antivirus, IPS/IDS, DNS filtering, and many things in that firewall. It also has a web application firewall WAF feature. On the feature side, it's a good firewall.

I think both AWS and Fortinet should think about that. They should provide it on lower instances as well. If I want to upgrade it from T2.small to T2.medium, it should be available, but it's a problem.

For how long have I used the solution?

I have been using Fortinet FortiOS since 2019, so more than three years.

What do I think about the stability of the solution?

Fortinet FortiOS is a stable product.

What do I think about the scalability of the solution?

Fortinet FortiOS is scalable. 

How are customer service and support?

Technical support is good. When I create the ticket, they respond to me, engage the engineer, and support is good. No issue at all.

How was the initial setup?

The initial setup is not too complex; it's simple.

What's my experience with pricing, setup cost, and licensing?

It would be better if it were cheaper. We have the firewall in our office, and the license is expiring in 20 to 25 days. We got a quote for almost 80,000 Pakistani Rupees, which is a little costly.

Which other solutions did I evaluate?

If I compare Fortinet FortiOS with Cisco Adaptive Security Appliance (ASA), it's a cool product. The deployment of ASA is a little bit complex because it's GUI-based, and ASA also has a graphical user interface. But I still think Fortinet is a good firewall compared to ASA because if you want to use the IPS/IDS feature in the ASA, you have to deploy the management center and integrate it with the firewall, which is a little complex.

What other advice do I have?

I recommend this solution to potential users because it has many features, and it's a stable product.

On a scale from one to ten, I would give Fortinet FortiOS an eight.

A seamless endpoint gateway solution with constant updates and a zero choice engine
Pros and Cons
  • "The most valuable features of Fortinet FortiOS are its constant updates and definitions."
  • "I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle."

What is our primary use case?

We use it for end-point gateway protection and also use the FortiOS for external user connection and server VPN. We love that clear synchronization as it's almost invisible with the fabric for the guests, externally to connect. The zero-choice engine that they use is pretty good. It is perfect for setting up one-to-one channels for different services that have to pass through the firewall. So it does that seamlessly.

What is most valuable?

The most valuable features of Fortinet FortiOS are its constant updates and definitions. The new definitions and the content information coming out to the threat labs keeps you updated on your signatures so that you know what's happening out there. And also doing well, for my system, we have, like, what is called, active scans.

It's constantly accessing Sophos into your gateway, even Sophos that you authorized.

What needs improvement?

I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle. I want to see if that enhances a bit more so I have granular datasets and the user level through to the gateway because that's where most of our threats come from. It's from user activities on the Internet and passes into your files over that gateway. That's where most of our threats would appear and where our exposure to vulnerabilities lies.

So if we can tighten that up, we can harden our infrastructure much better.

For how long have I used the solution?

I have been using the solution for quite some time.

How are customer service and support?

The customer support team is good and responsive.

How was the initial setup?

We did the initial setup ourselves, so it was easy. The learning curve was that great once you have any experience with any firewall or any experience with any security appliance, you can pull around it. We did get some help from our providers. But that was basic.

What about the implementation team?

The EMS setup was all in-house. Our service provider assisted with the firewall setup. The implementations were very smooth. And the transition of our current from our current security device to that when we did it a couple of years ago, it's seamless.

What's my experience with pricing, setup cost, and licensing?

The pricing is competitive for the medium and high markets but for the small markets it can be expensive.

What other advice do I have?

You have to see what works best for your environment. Each environment is different depending on the applications and different services you are running in that environment. Suppose it's a full Windows environment versus a mixture if you have a hybrid environment. It all depends on the type of environment you're running and finding the right tools that meet your domain.

But for the regular Windows environment, it's perfect.

I rate it eight out of ten.

Great SD-WAN, IPS, and application control
Pros and Cons
  • "It's very easy to use."
  • "They need to integrate more with the SD-WAN."

What is most valuable?

It's very easy to use.

The SD-WAN, IPS, application control and web features are all very valuable aspects of the solution.

What needs improvement?

We haven't had any issues with the solution. It's been pretty good in general. 

We would like to see the ability to maybe monitor applications that use the SD-WAN. They need to integrate more with the SD-WAN.

We would like to see lower pricing. The price is high.

For how long have I used the solution?

I've used the solution for a long time. It's been maybe ten years. 

What do I think about the scalability of the solution?

We have about 100 users on the solution. 

Which solution did I use previously and why did I switch?

I've also worked with Check Point. 

What's my experience with pricing, setup cost, and licensing?

We have three years' worth of licensing before we have to renew anything. We renewed it about two years ago. The pricing could be a bit better.

What other advice do I have?

I'm a customer and an end-user.

I'd rate the solution nine out of ten. It has worked well for us overall, and we are happy with its capabilities.

Reliable, low maintenance, and installation simple
Pros and Cons
  • "I have found the most valuable feature of Fortinet FortiOS is the low maintenance."
  • "The central management can improve in Fortinet FortiOS. It is sometimes difficult to manage all the devices."

What is our primary use case?

Fortinet FortiOS provides a full UTM experience, including UTM profiles, firewall rules, remote access, VPN connection, IPSec, and SSL connection.

What is most valuable?

I have found the most valuable feature of Fortinet FortiOS is the low maintenance.

What needs improvement?

The central management can improve in Fortinet FortiOS. It is sometimes difficult to manage all the devices.

I wrote my opinion about changes to the SSL-VPN authentication directly on the Fortinet forum, and they said that right now they will not change it. Hopefully, in the future, they will change the SSL-VPN authentication for groups and users.

For how long have I used the solution?

I have been using Fortinet FortiOS for approximately five years.

What do I think about the stability of the solution?

The stability of Fortinet FortiOS depends on the operation being done. If we are using the basic functions I would rate the stability of Fortinet FortiOS a five out of five. If we are using the advanced functionality I would rate the stability a three out of five. Overall the solution is stable.

How are customer service and support?

The support from Fortinet FortiOS is good. However, there are times they give a five out of five level of support and whereas other times they give a one out of five.

How was the initial setup?

Fortinet FortiOS's installation is easy.

What's my experience with pricing, setup cost, and licensing?

The scalability of Fortinet FortiOS is good. However, central management is intuitive for the end-users. We had a lot of questions about central management, and sometimes they didn't use it and did their firewall management directly on FortiGate instead of using Fortinet FortiOS.

What other advice do I have?

My advice to others is for them to read the instructions on how to use the solution.

I rate Fortinet FortiOS a nine out of ten.

Performs better than competing solutions
Pros and Cons
  • "Performance-wise, I think FortiOS is much better than its Juniper counterpart. Based on our actual experience and performance metrics, FortiOS-based products are much better than Juniper."
  • "They're using a lot of application-specific IC, so that may be causing some performance issues. And whenever a Fortinet adds new features, it can affect performance."

What is our primary use case?

We use FortiOS for the internet router and firewall for our customers' offices. In some of the smaller offices, there is only one FortiGate, but the hub site may have a pair of firewalls in an HA configuration.

What is most valuable?

Performance-wise, I think FortiOS is much better than its Juniper counterpart. Based on our actual experience and performance metrics, FortiOS-based products are much better than Juniper. We've experienced some trouble with Juniper in the past and some unstable, unpredictable performance on Juniper devices.

What needs improvement?

They're using a lot of application-specific IC, so that may be causing some performance issues. And whenever a Fortinet adds new features, it can affect performance. I don't handle implementation, so I have to ask my frontline engineers to implement new features, like software-defined WAN service. But I'm not sure these are stable and acceptable because this project is still in progress. FortiOS and all the other firewall products are adding SD-WAN service, and this kind of service needs a lot of resources from the fabrics, the hardware, and the software. Still, I think we have more confidence deploying this service with FortiOS than using the other brands, like Juniper.

For how long have I used the solution?

I've been using FortiOS for more than 15 years.

How are customer service and support?

Fortinet provides sufficient support, and their response time is reasonable.

How was the initial setup?

We have a team of around 10 engineers that manage FortiOS-based devices and all other firewall brands. 

What's my experience with pricing, setup cost, and licensing?

FortiOS has a UTM feature, for which you have to buy an annual subscription. Most brands of firewalls will also have such a subscription.

What other advice do I have?

I rate FortiOS at least eight out of 10, and we recommend it to our customers.
