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.

Application control excels and integration with monitoring system boosts efficiency
I am an integrator working with Palo Alto Networks CN-Series and Panorama. I have been involved with the implementation of Palo Alto Networks CN-Series The stability of Palo Alto Networks CN-Series is excellent. Application control is one of the most valuable features. Its monitoring capability…

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 simplicity of the product is great. It's very easy to use, which is a compliment we get all the time in terms of feedback."
"It is a safe product."
"We were looking for the VPN feature and controlling the inflow and outflow of all the traffic within the site and across the sites. We are also using it for the VPN and VLANs."
"The most valuable feature of this solution is the analytics."
"The performance is good."
"The ECC management and the GUI that offers single interface management are the most valuable features of Fortinet FortiGate."
"The FortiGate controls the user's activities and maximizes my bandwidth use overall."
"The strengths of Fortinet FortiGate include network security, VPN, site-to-site tunnels, client VPN solutions, two-factor authentication for VPN clients, and SD-WAN for branch level. We have implemented these solutions for various customers."
"The stability of Palo Alto Networks CN-Series is excellent."
"The app inspection is very helpful for network security."
"The solution is scalable."
"It provides in-depth visibility into your network, ensuring that traffic flowing into your organization, be it from offices or individual users, is effectively filtered and secured through multiple layers of protection."
"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."
"The product’s firewall and VPN package are fantastic compared to any other solution."
"It helps a lot of companies to reduce their downtime. Also, It helps businesses in terms of being secured and protected from any threats."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"Zscaler is still a very good product."
"Once you have Zscaler running you have access to configure it however you want."
 

Cons

"The visibility of the network can be better. The GUI can be improved for better visibility of the network flow. Other solutions have better GUI in terms of network visibility."
"The feature which gives us a lot of pain is ASIC architecture."
"The Web-filter in this solution is not very good."
"If I had any criticism that I would give FortiGate, it would be that they need to stop changing their logging format. Every time we do a firmware upgrade, it is a massive issue on the SIM. Parsers have to be rebuilt. Even the FortiGate guys came in and said that they don't play well in the sandbox."
"In most cases, the IPS engine uses too many resources, which makes Fortinet FortiGate devices unstable."
"You do need some IT knowledge in order to effectively work with the solution."
"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."
"Quality control on their firmware versions needs improvement. When they introduce new firmware, there tend to be bugs."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
"I'd like to see more IOPs features."
"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."
"Data Leak Prevention is only for web filtering and there is no protection for email."
"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."
"Zscaler Cloud Firewall should have a better understanding of all dynamic cloud applications."
"Its technical support services could be better."
"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."
"The product could improve its integration with some legacy systems."
"Certain criteria need to be met if you want to scale this solution."
 

Pricing and Cost Advice

"It was probably about $2,500 per firewall. It was all included. It included support, services, threat management software, and 24/7 FortiCare on it. Cisco products are more expensive."
"Fortinet FortiGate is reasonably priced."
"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."
"It is an inexpensive solution."
"The price of FortiGate is comparable to that of most other firewall solutions and is more affordable than Cisco."
"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."
"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."
"Go for long term pricing negotiated at the time of purchase."
Information not available
"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."
"There are different subscription models available."
"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."
"It is expensive for small businesses."
"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
"There are licensing costs, and I would not say that it's a cheap vendor."
"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."
