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.

I would rate Palo Alto Networks NG Firewalls ten out of ten because it is the best. Our disaster recovery site utilizes Palo Alto Networks Next-Generation Firewalls. We are also in the process of upgrading the firewalls at our 365 sites in Pakistan to Palo Alto Networks firewalls. While budget firewalls may advertise comparable features, they often fall short of effectively detecting viruses, threats, and ransomware. In contrast, Palo Alto Networks NG Firewalls, combined with Cortex XDR, provide comprehensive threat intelligence and detection capabilities, ensuring superior security coverage. I recommend conducting a proof of concept before selecting a firewall. This will allow you to evaluate different options and determine which best suits your needs. While Palo Alto offers robust firewall solutions, it's essential to compare them with other vendors to ensure you make an informed decision.

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

"The virtual firewall feature is the most valuable. We have around 1,500 firewalls. We did not buy individual hardware, and the virtual firewalls made sense because we don't have to keep on buying the hardware. FortiGate is easier to use as compared to Checkpoint devices. It is user friendly and has a good UI. You don't need much expertise to work on this firewall. You don't need to worry much about DCLA, commands, and things like that."

"SSL-VPN is very useful for us and has been very reliable."

"Initial setup is straightforward. There weren't too many issues with setting it up. It takes one hour or so."

"It has improved our security capabilities."

"Offers good security and filtering."

"One of the valuable features is a standardized OS."

"The web filtering feature and the intrusion protection system are the most valuable. It is a resilient appliance. I never had an issue with it in terms of any security breaches."

More Fortinet FortiGate pros

"I like the sandbox feature, and it's very good. It kills each malware deployment in the sense of signatures within five minutes. So, we can secure our network and infrastructure very well within the stipulated time. The WildFire functionality is very good because a few files are also getting blocked. It's critical as malware attacks are also getting ignored, and the logging is very well maintained in this firewall. The most valuable solutions in this field are application-based firewalls. That is the main criteria of the firewall and functionality. We can get all the logs related to this and each and every packet. I like that the firewall is working as an application. The application-based entity we have deployed is well maintained and working very well. We were able to find lots of vulnerabilities when we deployed it, but we could not disclose all. But there were vulnerabilities we could block by updating the firewall and taking actions on clientside machines. So, we got to know that we have lots of vulnerabilities inside the organization too, and we took lots of steps and resolved the number of vulnerabilities. Palo Alto Networks NG Firewalls is an all-in-one solution. It provides every entity log, which is a very good functionality of this firewall. It gives every packet and aspect that the firewall is performing through its logs, and it does it very well. This firewall's unified platform helped eliminate multiple network security tools. If anyone uses P2P sites, cryptocurrency websites, or any illegal sites, we can block it easily. It gives us a proper alert for these kinds of sites, and it properly secures our network. Monitoring is the best thing we are doing here, and we can block this kind of vulnerability as soon as it comes to us."

"This solution not only provides better security than flat VLAN segments but allows easy movement through the lifecycle of the server."

"I can enable the features I want and configure the policies based on the user and not all users and network traffic, making firewall management much easier."

"The fact that I can perform several security functions in one device at wire speed is a valuable feature. I don't have to slow down my business transactions, and I don't have to inconvenience my users with 16 different solutions. I can have it all in one box, and it protects my organization at wire speed."

"Prisma Access is the most valuable feature of Palo Alto Networks NG Firewalls."

"Flexible and integrates well with apps and other security tools."

"The DNS sync code in your filtering is the most valuable feature of the Palo Alto Networks NG Firewalls."

"All the features are valuable, but my main one is the straightforward and well-designed GUI. I'm over 50 and have been in this business since the internet started. I'm not a GUI guy; I prefer using the command line. The product's GUI is excellent, and so is the threat intelligence. It's also straightforward to configure and flexible. The solution even has good networking, such as VLAN and subinterfaces, which is great because, in my experience, if the firewall is good, then the router usually isn't and vice-versa, but Palo Alto has both."

More Palo Alto Networks NG Firewalls pros

"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."

"The solution is scalable."

"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."

"The solution offers good sandboxing."

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

Cons

"The setup is pretty complex and not easy to implement."

"The Wi-Fi controller needs a lot of improvement."

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

"Fortinet FortiGate could improve by having more storage in the hardware for log data."

"Some of the web policy reports could be improved."

"The support structure needs to be improved because every time we contact them, there is a delay in the response."

"There are some license issues. Not every feature must have a separate license. There must be some of kind synergy between the license so we don't have to pay for every individual license that we would like to have."

"I would like to see improvements in the product's application rules."

More Fortinet FortiGate cons

"There is room for improvement in the area of customer service."

"Having a better pricing model would make this product more competitive, and more affordable for our customers."

"The reporting and visibility are phenomenal, but you don't get that information out of the box. They can email reports regularly, and the functionality is all there. However, a lot of it is based on an older model for email, where customers have in-house email servers. The small and medium-sized business customers I deal with are moving toward Office 365 or some other cloud-based mail and not maintaining their own internal mail servers."

"It is a complete product, but the SSL inspection feature requires some improvements. We need to deploy certificates at each end point to completely work out the UTM solutions. If you enable SSL encryption, it is a tedious process. It takes a lot of time to deploy the certificates to all endpoints. Without SSL inspection, UTM features will not work properly. So, we are forced to enable this SSL inspection feature."

"Palo Alto Firewalls could improve by introducing more features, particularly in load balancing."

"The machine learning component on the firewall level requires more computing power to perform at the full production level."

"We are not happy with Palo Alto at all. It would be better if they provided more support for the firewall. We have a few pending issues with the configuration for each application. We cannot deploy them yet due to some support-related problems in the firewall. We have deployed a few policies for DNS spoofing and DNS attacks, but we could only block a few IP addresses through the policy. That's DNS security, and we have configured a few policies for DNS spoofing and more. URL categorization and URL filtering are not yet adequately maintained. For example, if you created a few rules in the rule-based configuration and made some rules downstairs, you will lose some of them if you give access upstairs. It's not giving us a proper solution for which route it is using. We need to apply the application-based policies and URL filtering-based policies. It creates more issues because we are not getting good support from the team."

"Palo Alto Firewalls could improve by introducing more features, particularly in load balancing."

More Palo Alto Networks NG Firewalls cons

"Certain criteria need to be met if you want to scale this solution."

"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."

"Instead of the standard license, they should certainly provide customers with the visibility to access and view the logs."

"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."

"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."

"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."

"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."

Pricing and Cost Advice

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."

"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."

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

"The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."

"The price is fair for what we get with FortiGate."

"If the customer is looking for SD-WAN, it comes free with FortiGate."

"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."

"The price is highly competitive when compared to other brands that offer similar functionality."

More Fortinet FortiGate pricing and cost advice

"Palo Alto Networks NG Firewalls' price is expensive."

"While Palo Alto Networks Next-Generation Firewalls may be considered expensive, their quality justifies the cost."

"We were very happy when they released the PA-440s. Previously, we had been looking at the PA-820s, which were a bit of overkill for us. Price-wise and capability-wise, the PA-820s hit the nail on the head for us."

"Palo Alto Networks NG Firewalls are very expensive compared to other firewalls such as Fortinet. As a result, Palo Alto is losing some of its market share."

"This is an expensive product, which is why some of our customers don't adopt it."

"Overall, it is commercially competitive compared to Cisco and Fortinet."

"Palo Alto Networks NG Firewalls are affordable, and we get what we pay for."

"It's very expensive. However, we usually use all of the subscriptions and threat alerts on any firewall that uses the internet. For each edge security endpoint, we use all subscriptions. Otherwise, we just utilize the threat alert, the antivirus, WildFire, etc."

More Palo Alto Networks NG Firewalls pricing and cost advice

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

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

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

"It is expensive for small businesses."

"There are different subscription models available."

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