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.

Cons

"The solution could be improved by addressing limited local reporting. It requires obtaining the FortiAnalyzer for proper visibility because you can't do much from a reporting perspective with just the firewall alone."
"The security of Fortinet FortiGate could improve."
"Fortinet FortiGate needs to improve to be on par with its competitors, such as Palo Alto and Sophos. They are the market leaders. Fortinet FortiGate needs to improve its capabilities. However, we are happy with Fortinet FortiGate."
"It can be a little bit more user-friendly in terms of policy definition and implementation. It seems a little bit complicated, and it could be simplified."
"It's my understanding that more of the current generation features could be brought in. There could be more integration with EDRs, for example."
"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."
"Fortinet FortiGate SWG should be localised to specific regions to comply with local data privacy regulations because of the data privacy rules in the countries. In the Middle East, data organisation and KFA requirements are stringent."

"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 can be some lagging issues because the product gets stuck at times, making it an area of concern where improvements are required."
"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."
"Increasing the tutorials and the help inside Kali Linux would make it more useful."
"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."
 

Pricing and Cost Advice

"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"Fortigate's pricing is competitive."
"I pay €1,200 per year for the license along with Fortinet's 81E firewall appliance. I would rate this pricing as 3/5 stars, and I believe the price is reasonably similar to its competitors in the market, being somewhere in the middle."
"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."
"The product is expensive compared to one of its competitors."
"It is around $50,000 per month."
"It cost us around $73,000 for three years."
"Fortinet FortiGate allows you to purchase licenses for hardware and software."
"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."
"Kali Linux is open source."
"The tool is open-source."
"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."
"I have used the free version."
"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."
