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

"The stability and scalability of this solution are satisfactory. Its SD-WAN, VPN, and URL filtering features are very useful."
"Web filtering and two-factor authentication are great features."
"I think that the UTM features are the most value, as it truly protects my infrastructure."
"The most valuable features of the solution are SD-WAN, filtering testing applications, web filtering, and the new VPN."
"The usage in general is pretty good."
"Its stability is the most valuable."
"The most important feature, normally for small business customers, is link load balancing."
"Virtual Domains (VDOMs) are a feature that we found valuable."
"Since it is really customizable, I can use it and avoid enabling access to the full network."
"Once you have Zscaler running you have access to configure it however you want."
"Includes advanced tech protection."
"The product’s firewall and VPN package are fantastic compared to any other solution."
"Most of the features that Zscaler has to offer, we will deploy."
"The scalability is okay. We have around 2200 people using this solution."
"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."
"If malicious traffic attacks our on-premises servers, then it gets blocked by Zscaler Cloud Firewall."
 

Cons

"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"To some degree, it's almost a question as to why some of this stuff isn't simpler. For example, for an AP deployment, while it's integrated, the number of steps that you have to go through in order to get the AP up, seems like a lot."
"I don't really have anything negative to say as far as Fortinet firewalls are concerned. If anything, they can support a user a little bit better. They can stop being so time-sensitive about how much time the support call has taken, and they can help you do it yourself."
"The firmware updates are sometimes not stable. The stability issues can vary, sometimes happening once a month or quarterly. New firmware updates can occasionally introduce bugs, causing some policies to fail. We then have to raise a ticket, and Fortinet usually provides a fix within a few days."
"With FortiGate, the main complaint that I have heard is about the technical support."
"The support team for Fortinet FortiGate needs to be more customer friendly."
"The graphical user interface of Fortinet's FortiGate product does not function well with text-based interfaces."
"The firewall engine is not so strong as of now, in my opinion... My second concern is that, while they have Zero-day vulnerability and anti-malware features, the threat engine needs to be strengthened, its efficiency can be increased."
"Its technical support services could be better."
"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."
"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."
"If I can get rid of Jetscaler, I will use Twingate for sure."
"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."
"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."
"I don't have the visibility of a control dashboard or a network management system."
 

Pricing and Cost Advice

"While Fortinet FortiGate has a higher price point compared to Sophos XG, its user-friendly interface justifies the cost."
"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."
"Fortigate's pricing is competitive."
"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."
"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."
"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"As far as I'm aware, in our case, it's just a yearly pricing arrangement with no additional licensing costs."
"Its price could be better."
"Zscaler is priced too high compared to the cost of Fortinet."
"There is an annual license required for the use of the Zscaler Cloud Firewall."
"It comes at a significantly reduced cost while ensuring control and effectiveness."
"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."
"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 not the most budget-friendly solution, but it's important to consider its overall value."
"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."

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
