Robust, scales well using FortiManager, and you have a choice of two different modes to run in

What is our primary use case?

We use this solution as a gateway, a firewall for the office.

Pros and Cons

  • "It is more robust than SonicWall, particularly on the VPN from site to site."
  • "I can only compare it with SonicWall, and it is missing many advanced features that SonicWall has."

What other advice do I have?

I know Fortinet and SonicWall, and If I had to consider other solutions or if I have to redo it again, I would take a closer look with Palo Alto first. With Palo Alto, the cost is more, but when I switch from SonicWall to Fortinet FortiOS, I lost a lot in the features. I would check to see if Palo Alto has what was lost in terms of features. The stability is good. I would rate Fortinet FortOS an eight out of ten.

Scalable, with extensive features and good technical support

What is our primary use case?

We primarily use the solution for our firewalls. Basically we're providing security distribution for our client. One of the solutions we utilize are firewalls. It helps secure the environment and monitor traffic.

Pros and Cons

  • "There are a lot of features that we like within the solution. The resources or performance of the firewall is very good. However, the real selling point is the fact that the solution offers so many features, it gives our clients a lot of extras that they can work with. There's a lot on offer."
  • "Right now, it's very trendy to integrate everything into the cloud. This solution would be more effective if they did more integration in that regard."

What other advice do I have?

We're using version 6.2 of the solution right now, however, the latest version available is 6.4. I'm part of the security team at our organization. We're business partners with Fortinet. I would advise other companies to choose a firewall brand that they can they afford. Cost is an important aspect. It needs to work well within an organization's budget. It doesn't make sense to look at products that are out of an organization's price range, so make sure you are looking at options that are affordable. The second thing to consider is the solution's functionality. If that particular brand or…

Provides an easy and simple means of filtering traffic and establishing VPN connections and authentication

What is our primary use case?

For me, personally within our company, I am using this for business administration, but the company as a whole uses the product as a general firewall solution.

Pros and Cons

  • "This is an easy means of setting up high-availabilty firewall protection."
  • "The support is not very good, but the product is stable so it is not so much of a problem."

What other advice do I have?

We have lots of experience in using and installing FortiOS, and because of the experience has mostly been positive, I recommend FortiOS as a solution for firewalling. Besides the few issues we have experienced in the past, this is a stable solution and the high-availability feature is very, very good. On a scale from one to ten, where one is the worst and ten is the best, I would you rate Fortinet FortiOS as a nine. Despite the few problems we had in the past it is a very good solution which does what it is designed to do.

Cost-effective solution for medium-sized businesses and mid-range corporations but it has some product limitations

What is our primary use case?

Our primary use case for this solution is for deploying network security systems for SMBs or mid-range corporations.

Pros and Cons

  • "A good network security system for medium-sized businesses with an excellent GUI interface that gives a graphic view of network status."
  • "While it is a solid solution, there are some product limitations which exclude it from deployment in some situations."

What other advice do I have?

I do recommend this product to clients for use but it depends on their case needs. For example, in the AAA (Authentication Authorization and Accounting) some of the accounting and some of the VPN tunneling features are removed from Fortinet FortiOS due to some security configurations. In some projects, we need those features for the client and when that is the case, I cannot recommend that the client use the FortiOS solution. It would be a better product if there were a logging feature. You need to have FortiAnalyzer in your installation to have logging management capabilities. It will be a…

Also offers email filtering and data loss prevention

What is our primary use case?

It's a security device. We use it to keep the bad guys away.

Pros and Cons

  • "All networks are security-driven, we get throughputs and security. We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding."
  • "It could more scalable for the lower end users."

What other advice do I have?

My advice to someone implementing this solution is not to take shortcuts. Shortcuts aren't good. Don't hesitate to use FortiGate's technical support. Always buy support. Always buy FortiCare. You can buy it for one year, two years, or three years with the initial purchase. We always buy it and sell it to our customers for three years. And the product will last more than three years. Fortinet competes in the big companies as well. We just don't. Our marketplace is the smaller users two or three, maybe four locations, 150 to 300 endpoints. So we're not dealing in the 10,000s of users trying to…

Flexibility makes this easy to integrate with other products, especially ACI implementations

What is our primary use case?

The primary use case is for integrated cybersecurity.

Pros and Cons

  • "The VDOM (Virtual DOM) is a virtualized firewall that has some opportunities for flexibility that are an advantage in certain configurations."
  • "The pricing model makes this product far more expensive than similar solutions."
  • "The implementation could be simplified."

What other advice do I have?

I would probably recommend Check Point to most users considering FortiO if they do not have any ACI (Application Centric Infrastructure) implementation or a Cisco ACI. If you could do a workaround on the ACI, then I would probably still recommend Check Point. But if you do not know how to make that type of adjustment or can not and you do not have any partners that need to access your systems, then it is better you go for Fortinet.

Easy to configure with an easy initial setup and good scalability

Pros and Cons

  • "FortiGate as a product is very easy to configure."
  • "Technical support could be better. Some competitors have much more responsive support teams."

What other advice do I have?

We work with a lot of manufacturers of firewalls. It's normally Fortinet, however, we also work with Cisco, Palo Alto, and Sophos. My company works with Barracuda as well. To be honest, I am not a specialist with Barracuda. I normally don't work with that. That said, typically, when we work with clients, one of the first solutions we will suggest will be Fortinet. We do normally also recommend Cisco first, as well, due to the fact we are Cisco partners. We're also partners with Fortinet. We have a deal with Palo Alto and our security center recommends Barracuda because of their other security…

Excellent integration with an open API and a very easy to use interface

What is our primary use case?

We primarily use the solution for banks, whereby they want to secure their edge network, to filter their web application and block forms, etc. We also are able to integrate AWS using secure channels. It's more robust and they have different modes including nap, flow, and proximity.

Pros and Cons

  • "The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly."
  • "The solution is good, but they have poor marketing in Nigeria. They need to market their product better."

What other advice do I have?

We are using the on-premises deployment model. We are an integrator, so we do integrations using Fortinet, Cisco, Sophos, and Palo Alto. If you're an SMB or a small enterprise, I would recommend Fortinet. I would advise users to make sure they are getting value for what they are paying for. I can say that Fortinet is not as expensive as the others, but it also gives good value. The main thing is not about the cost, but the value and Fortinet delivers on that front. I would rate the solution nine out of ten.
