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.

Enhances security with precise access control but has integration challenges
Overall, I would rate the product six out of ten. Because of the support and cost, I moved away from Cisco, but otherwise, it is a good product. Recommendation depends on the requirement. If lacking a proper team and being dependent on the OEM and partner, Cisco is not suitable. However, if the team is qualified with Cisco-certified people and the requirement is a big network, it can be considered. In today's hybrid work world, having an expanded gateway is more typical than having a single one. Thus, Cisco is unlikely to be recommended for a hybrid requirement unless in-house skills align. Otherwise, depending on partners and Cisco, it can be a risk. I rate the overall solution six out of ten.

We have improved network security with user-friendly controls and high threat intelligence
FortiOS is very user-friendly and easy to configure for L1, L2, and L3 personnel. Its web filtering, application control, and IPS features are very user-friendly, easy to manage, and deploy. The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs. FortiOS allows us to expand the number of users and devices as our network needs grow.

Quotes from Members

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

Pros

"FortiGate firewalls are user-friendly, and I like the security profiling features."
"From the firewall perspective, the rules and policies are very sufficient and easy to use."
"We use the FortiGate Sandbox to detect zero-day vulnerabilities, such as anomalies or malware, that are unknown and have not yet been discovered."
"Fortinet FortiGate appears to be scalable."
"We can use our devices to check all of the perimeters. It secures email websites."
"It blocks the vulnerabilities that can negatively impact us."
"Consolidated our network environment at all locations, but mainly at our datacenter."
"FortiGate has a strong security topic which allows all of the Fortinet devices to communicate and share information which makes their security more powerful."
"Cisco's engineer helped us with a lot of scripting to see what existed. Previously, we didn't have a proper policy. In fact, we didn't have any policy because we didn't have any firewall for the data center, so generating a policy was a big challenge. Cisco's engineer helped us to do some scripting and find out what kind of policy we can have and organize those policies. That was nice."
"The stability of the solution is very good. We can see that it gets even better with every release."
"I like the IPS feature, it is the most valuable."
"It's quite a capable box for UTM."
"I have found the stability of this solution really good. This is why I use it."
"The return on investment is not going to be restricted to just the box... Now, these genres have been expanded to cyber, to third-party integrations, having integrated logging, having integrated micro and macro segmentations. The scope has been widened, so the ROI, eventually, has multiplied."
"The solution's dashboard is fine, and in terms of support, Cisco is better than other OEMs in the market."
"The TAC is always very helpful. We pay for Tier 1 support, so we get whatever we need from them. They always give us a solution. If they can't give us an answer that day, they get back to us within at least 24 hours with a solution or fix. I have never had a problem with the TAC. I would rate them as 10 out of 10."
"The pricing is excellent."
"The most important features of Fortinet FortiOS are the ability to block and make white and black lists. Additionally, the filtering of user access to websites is useful."
"For my organization, it has become much easier to scan the firewalls because the solution is more user-friendly than competitors."
"The stability of Fortinet FortiOS is great."
"It is more robust than SonicWall, particularly on the VPN from site to site."
"I like that the firewall gives me a lot of control in terms of outgoing and inbound traffic, and it scores better in deep packet inspections when compared with the Azure Firewall."
"The classification of the websites is helpful."
"The most valuable features are the ease of use, and the overall simplicity, everyone can use it with a small introduction."
 

Cons

"It would be good if they had fewer updates."
"We had a minor problem where there was a major system upgrade on the hardware platfrom and the Mac client was not available as soon as it might have been. The PC client was available immediately, but we had to wait a month or so, before there was a mac client. I was slightly irritated that it was not ready on time, but it was eventually resolved."
"We would like to have the ability to disable some of the security functionalities."
"The pricing could always be better."
"Its price could be better."
"Monitoring and reporting could be better."
"The solution needs to improve its integration with cybersecurity."
"Fortinet already improved FortiGate, but in the current market, many brands of security devices have improved together. Fortinet still needs to catch up with market standards. Fortinet is lacking in features in comparison to competitors."
"The security features in the URL category need more improvement."
"They need a user-friendly interface that we could easily configure."
"The virtual firewalls don't work very well with Cisco AnyConnect."
"The reporting and other features are nice, but there is an issue with applying the configuration. That part needs some improvement."
"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."
"There used to be information displayed about the packets in a module called Packet Flow, but it is no longer there."
"If you need to reschedule a call with the support team when you face a new issue with the product, then it may get a bit of a problem to get a hold of someone from the support team of Cisco."
"Third-party integrations could be improved."
"The pricing of the product is too high."
"It could more scalable for the lower end users."
"The GUI could be improved to make it more usable, easier to administer, and easier to configure."
"The main challenge with Fortinet FortiOS is integration with third-party solutions. I don't see any other areas for improvement. Nowadays, all products work well for 50-60 percent of needs. We must only fulfill 60-70 percent of client requirements because they don't use 100 percent of product features. Banks and financial sectors might need more security features. I don't work much in banking, but they often use multiple products for different security layers, not just firewalls. They might use various products or APIs for different purposes. In the end, clients use the products that suit their needs."
"The threat time interval lags a little, especially if there's a heavy load on the firewall."
"I would like to see smaller and more frequent updates."
"They need to integrate more with the SD-WAN."
"There is no flexibility."
 

Pricing and Cost Advice

"The price depends on the size of the company. From the beginning, you just want to know the internet bandwidths, speed, and the number of users to be able to offer the right product and model. They have a lot of products in FortiGate according to the size of the company, like 200D and 300D."
"Work through partners for the best pricing."
"We are on an annual license to use Fortinet FortiGate."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"Licensing is usually on a three-year period."
"I give the pricing a nine out of ten."
"They are very competitive, but we like to have the factory warranty taken care of."
"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."
"In the past, I encountered several difficulties and misunderstandings with Cisco licensing, but now the situation has improved. The Cisco Smart Software portal is an excellent resource for keeping track of, upgrading, and researching information related to Smart Licensing and other relevant topics. It is extremely helpful. Unfortunately, since it is not my money and there is only one vendor, I am unable to provide any comments on the prices. Nevertheless, the system, along with its provision through the Cisco Smart Software portal, as well as the traditional license and subscription models, are excellent and highly beneficial."
"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."
"It's more expensive than Fortinet and Juniper. The price is high compared to other vendors. In general, for the license, it's not that expensive."
"Pricing is why we had to go for a UTM. For us to achieve what we needed, if we had gone with the ASA, the cost would have been high compared to getting one box (UTM)."
"The product is expensive."
"When it comes to Cisco, the price of everything is higher. Cisco firewalls are expensive, but we get support from Cisco, and that support is very active."
"If we compare it with FortiGate and the co-existing ASA, FortiGate is better in price."
"The pricing is fair compared to competitors."
"The support contracts are usually about $100 - $200 a device."
"The price of Fortinet FortiOS is comparable to other similar solutions on the market. We are on an annual license to use the solution."
"A medium 100 or 200 Series box costs around $3000, and the software cost is around 55% of the hardware cost."
"The software costs roughly half what the hardware costs. Overall, the product is expensive."
"We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future."
"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."
"The solution could have a better licensing model. It's a bit more expensive than other solutions. The annual subscription is very pricy in Fortinet. The cost could be reduced."
"Be sure to choose a licensing plan that leaves a little headroom so performance is not an issue."

Cisco ASA vs. Palo Alto Networks
Cisco ASA vs. Palo Alto: Management Goodies You often have comparisons of both firewalls concerning security components. Of course, a firewall must block attacks, scan for viruses, build VPNs, etc. However, in this post I am discussing the advantages and disadvantages from both vendors concerning…
