Has small footprint and low maintenance cycles
Pre-installed tools can provide basic training and security measures, which is helpful. However, these tools may not be sufficient to secure your workload fully. That's why it's important to complement them with other specialized security tools to enhance your overall security. Before using Kali Linux, make sure you know its pros and cons. It's a good system to learn because it's the best choice for some situations. It has default firewall settings that block everything by default. It's up to the user to decide how much they want to open up. Learning Kali Linux takes time because it relies on command-line tasks instead of graphical interfaces. Practice is key to becoming comfortable with it.
Jörg Kippe - PeerSpot reviewer
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

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

Pros

"The interface is good and straightforward to use."
"Kali Linux is much better than other OS because it gives you a good set of tools. It is preferred for vulnerability assessments and cybersecurity."
"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."
"We use the product for open-source intelligence and identifying vulnerabilities."
"The solution's stability is very good."
"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."
"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."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is the most mature solution in the market."

Cons

"From an improvement perspective, it should be made possible for users to learn about the product easily."
"The product should improve its security features."
"The product should integrate AI and GPT capabilities."

"There can be some lagging issues because the product gets stuck at times, making it an area of concern where improvements are required."
"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."
"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."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
