Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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 threat protection, antivirus, and even SSL encryption and decryption, and a few customers also use this firewall for web filtering and application control."
"Fortinet FortiGate is a stable solution."
"The most valuable features of Fortinet FortiGate that I found are its next-generation firewall capabilities with stateful inspection and antivirus, along with features such as a reverse proxy that are missed by some other firewall products such as Palo Alto or Check Point."
"The SD-WAN is the most valuable feature."
"The most helpful features of FortiGate include its firewall policy, specifically the user-based policy, which I find to be quite beneficial in managing our network security effectively."
"It's quite comfortable to handle the FortiGate firewall."
"I like Fortinet FortiGate's antispam filter, SPN, and clustering features."
"The initial installation is very straightforward."
"The product's initial setup phase is easy."
"Arista Edge Threat Management NG Firewall has positively impacted my organization by reducing botnet attacks."
"Phish Blocker is a valuable feature."
"Kali Linux positively impacts my organization by allowing us to monitor changes and security posture for the company."
"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 positively impacted my organization significantly as it aids in red team work and penetration testing."
"If you are looking for faster, better performance or scalability, then Kali Linux is the best."
"Kali Linux has the capability of real-time data scanning for vulnerability assessment for backend services, and that is actually very far more valuable."
"We use the product for open-source intelligence and identifying vulnerabilities."
"Kali Linux has positively impacted my work by facilitating and simplifying the setup for an operating system and installing tools."
"I'm mostly using for the web security web application, so end map and the troubleshoot will it's my price, and it's available in ColliNX."
 

Cons

"Its pricing should also be improved according to Indian market requirements."
"There were quite a few problems with the stability of the system."
"When we cluster the two Fortinet FortiGate boxes together we have some issues."
"The cloud features and integration could be improved."
"There are some problems that support cannot give you a logical reason as to why it happened. Technical support gave more than one reason it could be giving issues, but none of them solved the problem."
"Fortinet FortiGate could improve by having a frequent ask questions(FAQ) area for people to receive quick answers to popular questions. Additionally, it would be beneficial to have an SMS notification feature. For example, if you cannot access your email you could receive an SMS message."
"Fortinet should improve its software, as we are seeing lots of firmware versions generated for each vulnerability issue. It becomes difficult for us to keep updating the firmware frequently due to bugs."
"I would rate Fortinet support a six out of ten. The immediate response is not that good, particularly when raising a critical or P1 ticket; they lag in the immediate response."
"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."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
"There is a significant lack of examples for Kali Linux, so you always need to go to external resources to get examples on how to use several tools that come with Kali Linux."
"Unfortunately, my current tool runs on Windows 10, and its use is restricted to enterprise versions. Integrating this tool or similar functionalities into Kali Linux for non-enterprise users would be incredibly valuable."
"The product should integrate AI and GPT capabilities."
"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."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"I would like for them to offer more features for the free version in order for users to test them in their internal environment before purchasing."
 

Pricing and Cost Advice

"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."
"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."
"The product is expensive compared to one of its competitors."
"Its price is affordable and lesser than Cisco. Cisco is expensive. In terms of licensing, there is only one issue. If a customer's license has expired a month ago and they do the renewal after one month, Fortinet renews the license from the start of the previous month. The activation of the product is done from the previous month, not from the date of renewal. The customers usually shout and complain that because they are paying today, the renewal should start from today. The support contract renewals or licensing should be renewed from the date of renewal, but Fortinet starts from the day it had expired. It is a loss for customers. They might have had some problems because of which they did not take the license one month before. Fortinet should work on this. Cisco doesn't do this. Cisco always starts from the day they apply for the license."
"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."
"We are on an annual license to use Fortinet FortiGate."
"I rate FortiGate's pricing a five out of ten."
"Fortinet FortiGate is expensive."
"The tool is quite cheap."
"I consider it an averagely-priced tool."
"The licensing fee is expensive compared to other products."
"Kali Linux is open source."
"It is an open-source tool."
"Kali Linux is a free product, and you don't have to pay for a license."
"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 price is good because Kali Linux already provides a good bundle of tools."
"I have used the free version."
"The tool is open-source."
