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.

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

"It's inexpensive compared to some of the other technology out there."
"There is an easy process for configuring it, and it is straightforward to implement the device from scratch."
"The flexibility and ease of configuration are the most valuable features."
"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."
"It performs very well."
"One of the valuable features is a standardized OS."
"Whenever I need something, Fortinet improves and updates the software for me."
"The application control features, such as Facebook blocking and Spotify blocking, are the most valuable."
"It has been stable so far."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
"Zscaler is still a very good product."
"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."
"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."
"The initial setup is straightforward."
"Includes advanced tech protection."
"Zscaler provides effective protection against various cyber threats ensuring a safe environment"
"The visibility and log availability offered are highly valued for troubleshooting purposes, and this is a key factor driving customer interest in the firewall module."
 

Cons

"It should come integrated or have its own type of network monitor tool in a module. There should just be one package, and you are good to go."
"The cloud features can be improved."
"It should be more stable. There should be full integration within Fortinet products themselves as well as with other third-party products. Especially when you're not dealing with SIEM and the correlation of the security box, we want Fortinet to be able to share that information with as many other products as it can."
"FortiLink is the interface on the firewall that allows you to extend switch management across all of your switches in the network. The problem with it is that you can't use multiple interfaces unless you set them up in a lag. Only then you can run them. So, it forces you to use a core type of switch to propagate that management out to the rest of the switches, and then it is running the case at 200. It leaves you with 18 ports on the firewall because it is also a layer-three router that could also be used as a switch, but as soon as you do that, you can't really use them. They could do a little bit more clean up in the way the stacking interface works. Some use cases and the documentation on the FortiLink checking interface are a little outdated. I can find stuff on version 5 or more, but it is hard to find information on some of the newer firmware. The biggest thing I would like to see is some improvement in the switch management feature. I would like to be able to relegate some of the ports, which are on the firewall itself, to act as a switch to take advantage of those ports. Some of these firewalls have clarity ports on them. If I can use those, it would mean that I need to buy two less switches, which saves time. I get why they don't, but I would still like to see it because it would save a little bit of space in the server rack."
"We have an issue with hotel guest vouchers."
"The pricing could be a bit better, especially when you consider how they have the most basic offering priced."
"FortiGate is really good. We have been using it for quite some time. Initially, when we started off, we had around 70 plus devices of FortiGate, but then Check Point and Palo Alto took over the place. From the product perspective, there are no issues, but from the account perspective, we have had issues. Fortinet's presence in our company is very less. I don't see any Fortinet account managers talking to us, and that presence has diluted in the last two and a half or three years. We have close to 1,500 firewalls. Out of these, 60% of firewalls are from Palo Alto, and a few firewalls are from Check Point. FortiGate firewalls are very less now. It is not because of the product; it is because of the relationship. I don't think they had a good relationship with us, and there was some kind of disconnect for a very long time. The relationship between their accounts team and my leadership team seems to be the reason for phasing out FortiGate."
"The performance could be a bit better. Right now, I find it to be lacking. Having good performance is very important for our work."
"Licensing is not cheap."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"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."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"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."
"Pricing is a challenge."
"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."
"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."
"When it comes to customer support, there is room for improvement in Zscaler's service."
"Data Leak Prevention is only for web filtering and there is no protection for email."
 

Pricing and Cost Advice

"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."
"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."
"The price could be lower."
"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."
"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"The pricing or licensing of Fortinet FortiGate is quite effective as it offers different bundles that aggregate most required features, while also allowing clients the option to select specific components alone."
"The price is highly competitive when compared to other brands that offer similar functionality."
"The price of Fortinet FortiGate could improve, it is expensive."
"We got a much cheaper price than that provided by Fortinet right now."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"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."
"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."
"It comes at a significantly reduced cost while ensuring control and effectiveness."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"There are different subscription models available."
"Zscaler is priced too high compared to the cost of Fortinet."
