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

"FortiGate has a strong security topic which allows all of the Fortinet devices to communicate and share information which makes their security more powerful."
"Fortinet FortiGate is the best option on the market when it comes to firewalls."
"The web controls are what I appreciate about Fortinet FortiGate. We have extensive controls over areas where we could block external-facing IPs, external URLs. We can do geo-fencing with the firewalls, which is a good feature."
"The solution provides good threat intelligence feeds."
"One of the nice things about FortiGate is that it can be deployed on the cloud or on-premises. You can actually do both. That's the biggest reason why I stick with this solution as opposed to something like Cisco Meraki. Another nice thing is that I can log directly into a FortiGate or get to it through their FortiCloud access products. They're pretty reliable and consistent. One of the reasons why I started using the product was their single pane of management. I can deploy their line of firewalls in conjunction with their switching and access points, and I can manage the entire network from one interface. I don't have to log into one interface for the firewall, another one for the access points, and another one for the switches. These firewalls have access point controller functionality built right into the system, so I don't even have to purchase additional devices to manage them."
"Customers want to load balance more than eight lines or six internet lines. FortiGate is the only solution that can accomplish this."
"It's easy to manage. The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."
"The best feature of Fortinet FortiGate is its SD-WAN capability, which is included and differs from other products that require an additional license."
"Phish Blocker is a valuable feature."
"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."
"The product's initial setup phase is easy."
"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 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 impacted my organization positively because it has allowed for the better security of my applications."
"Kali Linux positively impacts my organization by allowing us to monitor changes and security posture for the company."
"I use the tool with Nmap to perform network audits. We use it to find vulnerabilities in our network through attacks. It's for those who want to launch or create viruses or perform attacks on systems. With Kali Linux, you can conduct penetration testing for networks, web applications, and Android mobile apps."
"Kali Linux has positively impacted my organization significantly as it aids in red team work and penetration testing."
"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 offers excellent features including being lightweight with low memory usage, easy installation, portability, and multiple architectures such as ARM architecture and server architecture."
 

Cons

"Fortinet FortiGate IPS could improve the VPN. There are times it is slow."
"Reporting is limited to providing an external appliance for improving the reporting capabilities of the FortiAnalyzer. It does not offer a central management and is also sold separably as an appliance."
"FortiGate may include AI capabilities and integrate external threat intelligence. However, version management and backup/restore operations could be improved."
"They should do a better job in testing when they put out a new release because when a new software version is released, it is not always stable or does not always have all the previous features working correctly."
"From my experience, I see that the datasheets of the Fortinet FortiGate portfolio need to be more accurate because correct sizing is essential."
"They could simplify their deployment process, especially when customers have existing devices."
"Security is a continuous process. In every product, there is a requirement for improvement. Its pricing should also be improved according to Indian market requirements. They must also improve on the reporting part. Its reporting can be more precise. If we can get a real-time report in a specific format, it will be helpful for customers to know about the current status of their security."
"Its reporting and pricing need improvement."
"The documentation is not clear."
"The product has a lot to improve in the area of policy implementation."
"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 only point that I didn't find on Kali Linux for now is the ability to customize port scanning."
"The tool is slightly difficult to learn."
"Kali Linux can be improved, as I have encountered challenges with dependencies that can be overwhelming."
"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."
"Many users utilize Kali Linux through virtual machines. Sometimes Kali Linux has issues detecting hardware such as inbuilt or external Wi-Fi adapters."
"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."
"I think Kali Linux can be improved because it is not a beginner-friendly operating system."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
 

Pricing and Cost Advice

"By default, they give SD-WAN along with the firewall. They don't have separate licensing for the SD-WAN functionality. However, they have security licenses that are sold separately on a subscription basis. Customers can consume these security features to protect their users from internet traffic."
"It is quite affordable for our customers. There is a separate cost for IPS, antivirus, web filtering, and other features. They have a great choice of licenses. You can go for the license that you want, which is quite useful."
"Pricing for Fortinet FortiGate SWG is more suitable for enterprise or large-sized organizations because they are the ones who can afford it versus small and medium-sized organizations."
"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."
"Its pricing is competitive with other solutions."
"The license is too expensive to renew. The license renewal process is also complex."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"The pricing is comprehensive and clear. You can easily understand what you are purchasing, including which features correspond to each license and maintenance contract. Overall, the information is straightforward. Additionally, compared to other vendors, their prices are competitive."
"I consider it an averagely-priced tool."
"The tool is quite cheap."
"Kali Linux is open source."
"The tool is open-source."
"I have used the free version."
"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."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"I use it free of charge."
"Kali Linux is a free product, and you don't have to pay for a license."
"It is an open-source tool."
