Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Helped with the consolidation of tools and has a great dashboard
We have used different types of solutions. We had Cisco ASA for about 10 years, and then we switched to an on-site firewall to MX from Meraki, Cisco. For our cloud, we have Cisco Services Routers. The migration to the cloud has been a lot of work. Not all of our systems were compliant with being on the cloud so we had to work on some applications and delete some of them. For the old systems, we had to do extra work but for the newer systems, it was fine. The migration took around 18 months to migrate 99%. We had more than 2,000 on-prem firewall sites. Cisco helped with the migration to the cloud with the migration tool. Migrating MX was really easy and the tools helped us to migrate from the old ASA we had to the new MX. The cloud, firewalling, and CSR helped us from the data center on-premise approach to the cloud because at the time we didn't have a lot of experience with the cloud. It was easy to use the Cisco appliances in that space. I think that this solution has saved our IT staff time because of the ease of deployment. When I first started as a network engineer, it took a whole day to configure a firewall because of all the particularities you could potentially have at a site. I think that this solution saved our organization's time because security saves money because. At the end of the day, firewalls block threats. This solution helped with the consolidation of tools as we had all the observability tools in the solutions. Some 10 years ago we all had third-party solutions doing the observability. Now, we have the whole package and not only the firewall. We choose Cisco 10 or 20 years ago mostly because it was a market-leading solution. I also think it's because of MX's user-friendly solution that you can get on board easily. As far as CSA goes, I believe it's because you have a lot of features on the firewalls and it's the stability of course.

Great IPS and DNS filtering with useful tutorials available  
We don't really find a lot of issues on it. If I really have to complain about something, and there's not much, is the free VPN solution is a bit limited. Then again, it is a free solution. That's essentially it. Nothing else on the FortiGate or on the Fortinet OS side is really an issue. That's one of the main reasons why we use them: everything works and works well. For what we use, there isn't really any missing feature. In fact, we actually want to get rid of some of the features that they have due to the fact that, for the security model that we need to implement, having more features actually opens up potential risk. We actually would like to have a device that is more focused specifically on OT environments the operational technologies. We would prefer a device that's stripped down, that doesn't have all the other fluff in the more enterprise system. We actually want a feature where we can remove features that are there that we don't use. That is actually a thing that we find. We use it now in an operational technology environment. We use normal IT equipment. However, it's not a normal IT network. It differs significantly from a normal corporate IT environment. In a normal corporate IT environment, you like the fluff, and the additional features, and you can click, click, click, and you're done. However, all of those features you add to a device open up risk for us. And that is something we do differently in the OT environment in operational technology. We prefer to not have the fluff. We prefer to have only what is needed for the device to do what it needs to do. For example, imagine an additional feature for some sort of additional VPN technology has been added. However, it's not really needed for the OT environment, and it's not configured on the device, yet there's some sort of security threat in there. Now, all of a sudden, somebody can hack your system, and he's in there, and he's switching the lights on and off the entire city. And you don't know about it due to the fact that the additional fluff that we added to the system, we weren't aware of that issue was on there. You can enable and disable certain modules in it. However, with disabling, nobody can really tell us if that module is disabled. Is it really disabled? Is it actually unloaded? Is it uninstalling Word from your laptop, or is it just not running Word?

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Easy to use support and licensing portal as well as activation process."
"Its performance in fulfilling our requirements has been satisfactory."
"The IPS is good. It protect my network from attackers."
"Their interface is very easy to use, it is without bugs."
"The pricing is great and very reasonable."
"The feature I like most is the SD-WAN. It allows you to manage more than one ISP at the same time. And there is a high-availability mode, so if one of your ISPs is down, you still have a backup."
"UTM/NGFW features and FortiCloud for logs and backups are awesome."
"User-friendly and affordable security solution that's recommended for SMB customers. This solution has good technical support."
"The monitoring dashboard is valuable to us for troubleshooting."
"Our company operates in Saudi Arabia, primarily working with government sectors. If any hardware malfunctions, the defective device is removed, and we receive a replacement from the reseller. We have not encountered any issues related to delays in receiving replacements for malfunctioning devices which has been beneficial."
"Since the product is stable, we do not have to spend additional money to buy other firewalls. Once deployed, we can use the product for a long time. Thus, it is cost effective."
"Unfortunately in Cisco, only the hardware was good."
"Provides good integrations and reporting."
"I like the way Firepower presents the data. It gives you two classifications for the evidence, something based on the priority of the evidence and another classification based on the impact of the evidence in your environment. This makes it very easy to spot the evidence that is most impactful to my environment. Instead of having to go through all the evidence based on that priority, I can focus on the evidence that has the most impact on my environment."
"It's very stable and mature."
"Their performance is most valuable."
"The most valuable features of Fortinet FortiOS are the granular control and their interoperability is good."
"It is more robust than SonicWall, particularly on the VPN from site to site."
"I find filtering traffic, filtering web traffic, session traffic, and managing the network as valuable features."
"The initial setup is straightforward, and it is very customer friendly."
"The most valuable features of Fortinet FortiOS are user-friendliness, ease of use, and threat prevention."
"The firewall options in FortiOS allow us to open up access to our vendors for EDI and all its features."
"What I like about this solution, is that it is the only solution that currently offers VPN for clients."
"I personally think the site-to-site VPN is the most useful feature. A lot of firewalls have that, but to me, that's one of the features that's essential."
 

Cons

"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."
"They should improve high CPU and memory usage that occurs."
"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."
"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."
"For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial."
"The logs need to be better. They need to be more visible and easier to access."
"Palo Alto has a feature called WildFire Analysis that is unavailable in FortiGate. WildFire is better than a sandbox because it can address zero-day threats and vulnerabilities. It can immediately identify zero-day threats from the cloud."
"The improvement is related to logs. Instead of the CLI, we should be able to have more insights into the logs of the firewall in the GUI."
"Third-party integrations could be improved."
"There is huge scope for improvement in URL filtering. The database that they have is not accurate. Their content awareness and categorization for URL filtering are not that great. We faced many challenges with their categorization and content awareness. They should improve these categorization issues."
"We're getting support but there's a big delay until we get a response from their technical team. They're in the USA and we're in Africa, so that's the difficulty. When they're in the office, they respond."
"For what we use it for, it ends up being the perfect product for us, but it would help if they could expand it into some of the other areas and other use cases working with speeding up and the reliability of the pushes from the policy manager."
"<p>If there is old hardware, or appliances, it does not necessarily work with the new Cisco generation firewalls."
"Security must be increased when a new user connects over the LAN and an alarm must be generated."
"The inclusion of an autofill feature would improve the ease of commands."
"It would be great if some of the load times were faster."
"FortiOS's bandwidth and interface could be improved."
"For monitoring purposes, we don't have any option to monitor the ISP link."
"Fortinet FortiOS's integration could be improved."
"There are some issues with the performance. We also had some issues while updating the firmware."
"The complexity of the VPNs should be improved."
"The GUI could be improved to make it more usable, easier to administer, and easier to configure."
"It would be great if they can push the Microsoft updates through Fortinet OS and provide a centralized patch management system. They should also include the data loss prevention (DLP) and data leakage prevention features. They could also add network monitoring more effectively."
"It could more scalable for the lower end users."
 

Pricing and Cost Advice

"Our licensing costs are on a yearly basis."
"If the customer is looking for SD-WAN, it comes free with FortiGate."
"Setup cost may be not so low, as you expect, because it depends on different factors, but TCO for 5 years may pleasantly surprise you."
"The price of Fortinet FortiGate when compared to other solutions is high. However, my knowledge of the price is from third parties and I am not sure how accurate it is. I typically work in the technical area of my organization."
"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."
"The pricing for this solution is good."
"The pricing is fair."
"There is a license to use Fortinet FortiGate."
"Pricing is the same as other competitors. It is comparable. The licensing has gotten better. It has been easier with Smart Licensing."
"The pricing for Cisco products is higher than others, but Cisco is a very good, strong, and stable technology."
"Be sure of what features you are ​going to utilize to add/remove some from new bundles."
"Cisco recently has become very expensive."
"Everything with Cisco is expensive. My advice is that there are a lot better options out in the market now."
"The one-time cost is affordable, but the maintenance cost and the Smart Net costs need to be reduced. They're too high."
"The cost of keeping the licensing up on the ASA is very expensive. It has a lot of positives, but the cost of going with it is really starting to be a major negative right now."
"Licensing, recently, has been getting more complicated. In particular, the Smart Licensing that came out is quite complicated. I don't know what's going on.... They call it Smart, but it's complicated. I prefer the traditional license where you buy it once."
"A medium 100 or 200 Series box costs around $3000, and the software cost is around 55% of the hardware cost."
"The Fortinet solutions can be a bit expensive."
"We had a three-year license to use Fortinet FortiOS and we are going to renew it this year."
"The solution is cost effective. I would rate the pricing a five out of ten."
"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."
"I am on a two-year contract and I pay annually for Fortinet FortiOS."
"The price of Fortinet FortiOS is reasonable and it is paid annually. You are able to select the features that you want."
"The price of Fortinet FortiOS is comparable to other similar solutions on the market. We are on an annual license to use the solution."
