A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Perimeter security has reduced botnet attacks and now needs better interface and logging
The best features Arista Edge Threat Management NG Firewall offers are its ability to push a lot of traffic along with bandwidth management and traffic policy. Bandwidth management and traffic policy help my organization by keeping our internet subscription low. Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks. Immediately after I installed the firewall, it stopped a few botnet attacks.

Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a good source for firewall protection."
"The most effective features for threat prevention are the IPS, content filter, and SD-WAN capabilities."
"The solution is easy to use."
"The firewalls are valuable for threat prevention."
"It's very easy to set up, it's very easy to make policies and, for an organization, that means you don't need IT expert in firewalls. You just need to have somebody who knows a little bit of IT, and that's it. With other products, you need someone with a "Masters" degree in firewalls."
"The pricing is excellent. It's much less expensive than Cisco."
"The most valuable feature is the deep inspection for traffic, which is capable of identifying zero-day attacks."
"The most valuable feature of Fortinet FortiGate SWG is inspection."
"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."
"The product's initial setup phase is easy."
"Phish Blocker is a valuable feature."
"If you are looking for faster, better performance or scalability, then Kali Linux is the best."
"Kali Linux offers excellent features including being lightweight with low memory usage, easy installation, portability, and multiple architectures such as ARM architecture and server architecture."
"Kali Linux offers excellent features including being lightweight with low memory usage, easy installation, portability, and multiple architectures such as ARM architecture and server architecture."
"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"In general, Kali Linux is used for hosting applications, developing new applications, and operating systems. It's also used in containers and nodes. The tool offers a smaller footprint than Windows because it lacks the functionality of graphical user interfaces. One advantage of Kali Linux is its lower maintenance requirements than Windows, with slower update cycles and easier maintenance procedures."
"Kali Linux has the capability of real-time data scanning for vulnerability assessment for backend services, and that is actually very far more valuable."
"Kali Linux has helped me significantly in simulating penetration testing and other activities, and since all the tools are open source, I can easily modify and customize them based on my needs."
"Kali Linux is a very good tool and a good overall operating system to use when it comes to penetration testing, as it has a wonderful set of tools."
 

Cons

"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."
"The pricing could be reduced or include the first year warranty."
"There aren't really any negative aspects to discuss."
"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."
"In our case, the deployment options of FortiGate Next Generation Firewall (NGFW) are not scalable, but in terms of connectivity to other companies, that's exactly what we needed, and that's exactly what it does perfectly, what is needed."
"The product has to be upgraded every few weeks."
"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."
"Currently, without the additional reporting module, we only have access to basic reporting."
"Arista Edge Threat Management NG Firewall can be improved, particularly the user interface, which is not very good, and also the logs, which are not very good."
"The documentation is not clear."
"The product has a lot to improve in the area of policy implementation."
"From an improvement perspective, Kali Linux could include more ML to help with academic literature, as it is one of the areas where there are shortcomings in the solution."
"However, something about it might be improved, maybe the overall smoothness of it, because there are sometimes when I try to run a lot of applications, it tries to hang up on me."
"There are areas for improvement in Kali Linux, particularly regarding its use of the Linux kernel, which requires external additional patching, and the fact that network services are disabled by default, which complicates usage; enhancing user-friendliness through more GUI-based tools and better integration could be beneficial."
"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"I think Kali Linux is good, but there is a widespread misunderstanding related to Kali Linux because many people believe Kali Linux is a tool for hackers and that anything can be hacked using it."
"Increasing the tutorials and the help inside Kali Linux would make it more useful."
"The only point that I didn't find on Kali Linux for now is the ability to customize port scanning."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
 

Pricing and Cost Advice

"I rate the product's pricing a seven out of ten. The additional cost depends on the extra feature requirements."
"The solution could be better priced."
"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."
"The pricing for this solution is good."
"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 of Fortinet FortiGate is the lowest in the market."
"If you compare Fortinet FortiGate with Sophos and other firewall products available in the market, this solution is affordable."
"It is somewhat expensive compared to other solutions such as Sophos."
"I consider it an averagely-priced tool."
"The tool is quite cheap."
"Kali Linux offers a perpetual license, meaning you pay for it once and can use it. While free versions of Linux are available, Kali Linux, being an enterprise edition, usually comes with a perpetual license. I rate its pricing a five out of ten."
"The licensing fee is expensive compared to other products."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"I have used the free version."
"The price is good because Kali Linux already provides a good bundle of tools."
"Kali Linux is a free product, and you don't have to pay for a license."
"Kali Linux is open source."
"I use it free of charge."
