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.

Easy setup and effective traffic routing enhance security

In terms of improvements, I think the price could be a concern as Azure ( /products/microsoft-azure-reviews ) services are often more expensive compared to other firewalls. However, the functional aspects of Azure Firewall met our needs. While I found the interface not particularly user-friendly, this is a common issue across vendors.

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

"FortiGate is flexible and easy to use."

"Unified Threat Management (UTM) features."

"The most valuable feature is the SSL VPN, as it allows us to connect and it separates this product from other firewalls."

"I only deal with it from a security analyst's point of view. I don't really get into the features of the actual FortiGate. From the security point of view, it works, and it does its job."

"The most valuable features of Fortinet FortiGate are the different types of profiling. It has been the most effective for me. The WAF and the antivirus profile are the most effective in network protection."

"The solution is stable."

"I like how we can achieve total integration."

"It is useful for protecting and segregating the internal networks from the internet. Most of our customers also use the FortiGate client to connect to their offices by using the VPN client, and of course, they usually activate the antivirus, deep inspection, and intrusion prevention services. They are also using it for web filtering and implementing various policies dealing with forwardings, NAT, etc."

More Fortinet FortiGate pros

"We use the solution for application and server deployment."

"The SIEM that Azure Firewall provides us is very robust."

"Azure's cost-effectiveness is its major advantage."

"Great security and connectivity."

"Network filtering is valuable. The scalability capability from the cloud-native service helps us a lot because it simplifies our day-to-day maintenance activity."

"The solution has many useful features. For example, the solution allows users to create virtual IP addresses."

"I like that you can deploy the policies separately from the firewall."

"Performance and stability are the key features of this product."

More Azure Firewall pros

"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 solution is scalable."

"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."

"Once you have Zscaler running you have access to configure it however you want."

"Since it is really customizable, I can use it and avoid enabling access to the full network."

"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 is still a very good product."

"Includes advanced tech protection."

More Zscaler Cloud Firewall pros

Cons

"While FortiGate is cheaper than most other solutions, we're seeing increased license renewal costs. Most of our clients are asking for more significant discounts because the price is going up."

"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security."

"I have to say that the initial setup was complex. The deployment took a few days to get set up. Initially, we were using an IPVanish. We switched to this tool since we thought it would be easier. But it turns out it wasn't easier to set up and run."

"Fortinet FortiGate can be integrated with different platforms. They have integrations in place, but I can't say they're 100%."

"FortiGate can improve its token system, as it requires a purchase before use."

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."

"There are some cloud-based features that could be much more flexible than they currently are."

"The solution is very expensive."

More Fortinet FortiGate cons

"In my experience, Azure Firewall is quite expensive, with a high cost. I would rate its pricing a two out of ten."

"The solution lacks artificial intelligence and machine learning. It might be in the roadmap. However, currently, it's not available."

"Azure Firewall is an expensive solution. On a scale from one to ten, where one is not affordable, I would rate the price as a three."

"The threat intelligence part could be better. I don't see why our customers have to get an additional solution with Azure Firewall. It would be great if they made it on par with Palo Alto."

"The product could be made more customizable."

"It is a cloud service, but the lending speed for each region is not always the same. For example, in China, the speed is slow. They need to think about how to make sure that the service pace or speed is always the same in all regions. It would be a great improvement if they can provide the same pace worldwide."

"I would like the premium and standard features to be available on the basic package. Additionally, it lacks some functionalities when compared to competitors like Check Point and Fortinet, such as WAF or load balancing."

"It needs a lot of improvement, especially on intruder detection. They are working hard on that."

More Azure Firewall cons

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

"Its technical support services could be better."

"If I can get rid of Jetscaler, I will use Twingate for sure."

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

"Pricing is a challenge."

"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."

"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."

"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."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"We are on an annual license to use Fortinet FortiGate."

"I would rate the pricing a five out of ten"

"They need to be competitive with other solutions."

"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."

"Pricing is lower than Cisco."

"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."

"The price is high compared to some of the other solutions."

"The license is too expensive to renew. The license renewal process is also complex."

More Fortinet FortiGate pricing and cost advice

"It is expensive, especially with the premium functions. For one of the clients, it was very expensive. You have to use it more at an enterprise level, and there, it was not at an enterprise level. So, it was very costly, but security-wise, it was a very wise decision to use it that way."

"Azure Firewall is expensive."

"I rate the product pricing a five out of ten."

"Azure Firewall comes with Azure native services. We did not buy any kind of license for it. Whether you have a free subscription or a pay-as-you-go model, you can deploy the Azure Firewall service... The amount that you use will determine how much you pay."

"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."

"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."

"Azure Firewall is more expensive. If Microsoft can make Azure Firewall cheaper, I can see that all clients will think of using it. One client used FortiGate because it is much cheaper. Some clients ask me for Cisco, but in the cloud estimate, I found its cost is the same as Azure Firewall."

"Azure Firewall is quite an expensive product."

More Azure Firewall pricing and cost advice

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

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

"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."

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"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."

"It is expensive for small businesses."

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