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.

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

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

Pros

"The solution is very easy to understand. It's not overly complex."

"The most valuable features of Fortinet FortiGate are the ability to work in proxy mode, which other solutions, such as Palo Alto cannot. There are some features that are better that come at no extra license or subscriptions cost, such as basic SD-WAN. The DLT is useful, other solutions have the same feature too, such as Palo Alto."

"This version is stable. I don't have any issues with this solution, in our environment, it works well."

"Its stability is the most valuable."

"The product is very stable, easy to troubleshoot, and configure, so it has reduced the time it takes for support."

"I would recommend using Fortinet FortiGate because of its usability."

"The SD-WAN is the most valuable feature."

"Fortinet FortiGate brings numerous benefits to my company."

More Fortinet FortiGate pros

"The solution is excellent for enterprise-level networks."

"The Firepower IPS, based on Snort technology, has an amazing detection engine and historical analysis capability of files that eases threat investigations a lot."

"It's very stable and mature."

"The transparency of the single UI to ensure security. A product has to be simple so that an administrator can use it."

"It is much better than most of the other firewalls that I have worked with."

"To be honest, all of the features that are provided, all the other vendor will also have. One feature we did find valuable was the CLI, it is more accurate. Additionally, I was happy with the customization, dashboards, access lists and interface."

"VPN, firewall, and IDS/IPS allow us to deliver services to meet client needs across various industry verticals."

"Its security and filtering are most valuable. Every layer of data that comes into the organization goes through it. After setting up the criteria, it automatically filters the traffic. We don't have to check it often."

More Cisco Secure Firewall pros

"Includes advanced tech protection."

"It is a stable solution."

"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."

"Most of the features that Zscaler has to offer, we will deploy."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"The scalability is okay. We have around 2200 people using this solution."

"Zscaler provides effective protection against various cyber threats ensuring a safe environment"

"Zscaler is still a very good product."

More Zscaler Cloud Firewall pros

Cons

"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production. Other issues relate to isolation with Cisco products and your server."

"I would like reporting to be improved and should offer a lot more tools to monitor the products."

"The biggest "gotcha" is that if the client purchases what they call the UTM shared bundle, which has unified threat management on both, it's not as easy to manage if you have more than one firewall."

"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats. Fortinet FortiGate is able to ensure these threats do not enter, but we would prefer to see more proactive alerting mechanisms come out."

"Its price could be better."

"We would like to have the ability to disable some of the security functionalities."

"You do need some IT knowledge in order to effectively work with the solution."

"The SD-WAN functionality is a bit overly complicated and not fully documented."

More Fortinet FortiGate cons

"Technical support takes a long time to respond."

"It is confusing to have two management interfaces, e.g., ASDM and Firepower Management Center."

"When we're looking at full-stack visibility, it can be difficult to get the right information out of Firepower."

"The application detection feature of this solution could be improved as well as its integration with other solutions."

"The cost is very high. Most organizations cannot afford it."

"The Sandbox and the Web Censoring in this solution need to be improved."

"I'm working on a slightly older version, but what it needs is a better alert management. It's pretty standard, but there's no real advanced features involved around it."

"Most of the features don't work well, and some features are missing as well."

More Cisco Secure Firewall cons

"Apart from the issues associated with the product in areas like the DC performance issues and DC failover, Zscaler Cloud Firewall's IP should not have a proxy IP."

"We are having some issues with internet access being denied when organizational ID-based policies change. For example, a lower level employee ends up getting the same level of access as that of a higher level employee."

"Its technical support services could be better."

"When it comes to customer support, there is room for improvement in Zscaler's service."

"It would be nice to have some sort of a form factor, a physical form factor perhaps, or virtual machine that you could install on devices or on a cloud, and have some cloud computing."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."

"Because it's on cloud, it doesn't allow application of extra settings."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

"Its pricing is fine. It is on a yearly basis. Other than the licensing fee, there is no extra fee."

"The price for the device and software is high. However, the solution is of good quality and has a lot of features."

"We purchased a five-year bundle package, which worked out cheaper than competing solutions."

"Its price is normal. If I compare it with other vendors, such as Palo Alto, it's normal. Palo Alto is expensive."

"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."

"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."

"I had to pay for the license for the firewall, but it is guaranteed to have updates. I expect a good service for it. It was about €1000 for a year, and there was no additional cost."

More Fortinet FortiGate pricing and cost advice

"The licensing models that are available for Cisco Secure Firewall are okay. You have nearly every option that you need. You can pick filtering, advanced malware protection, or all the available features. It's sufficient. In terms of pricing, there are, for sure, some cheaper vendors, but overall, it's nearly the same. It has a fair price."

"The ROI is good. Using ASA, we have saved 10% to 20% on our costs."

"We normally license on a yearly basis. The hardware procurement cost should be considered. If you're virtual maybe that cost is eradicated and just the licensing cost is applied. If you have hardware the cost must be covered by you. All the shipping charges will be paid by you also. I don't thing there are any other hidden charges though."

"We're using the smart license for this firewall. The models that we have require licensing for remote access."

"There is room for improvement in the pricing when compared to the market. Although, when you compare the benefits of support from Cisco, you can adjust the value and it becomes comparable, because you usually need very good support. So you gain value there with this device."

"The price is not too high, but the subscription is a little bit high. We compared the activation of Cisco and Fortinet, and when we activated the whole portfolio of the UTM of Fortinet, the speed reduced. We tested the same situation with the Cisco 2140 series, and there was no reduction in speed."

"In terms of scalability, it is really expensive. It is scalable, but when it comes to pricing, the upgrading is a bit high."

"I'd say it's probably well-priced."

More Cisco Secure Firewall pricing and cost advice

"There are licensing costs, and I would not say that it's a cheap vendor."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."

"It is expensive for small businesses."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."

"Zscaler is priced too high compared to the cost of Fortinet."

"It comes at a significantly reduced cost while ensuring control and effectiveness."

"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."
