SQLmap for web application testing and good for web application penetration testing, network testing, vulnerability assessment of any devices or domains
Sometimes, I do face challenges. There's an issue where sometimes during the initial installation, it doesn't install properly. It gives multiple errors like packages not installing, so we have to install those tools separately. For instance, if we want to install a network or other tools, we have to install those complete toolkits manually. So, the challenge is with the initial setup, where I sometimes get errors. Regarding wireless attacks, OS attacks, and social engineering... the tools should be easier to learn because I know everything very well, but some people in my team struggle to understand. If there were GUI interfaces for the tools, it would help me guide my team in using them step-by-step. Command lines are very difficult for other team members who know the tool's purpose but not the Linux commands. GUI interfaces need more improvement. So, the UI interface needs improvement to make it more visible and easier for users. Expert users can do everything without any issues, but new users will struggle.

Reliable patch management, high uptime, and incredible knowledge base
In terms of security, it does a lot of things that most people still turn off. SELinux is turned on by default. They have pretty good firewall rules in their defaults. The audit rules always take tweaking, but, overall, it comes out of the box not too bad. I used to write scripts to harden them from there. There are multiple ways to provision and patch. You have everything from local repositories to doing it by hand. Their knowledge base is incredible. There is so much information out there. It has never taken me longer than 30 minutes to find an answer to anything, even very tough ones. One company I worked for was a security company, and we did a lot of patching on everything. It was designed around security and email hosting, and uptime was pretty much whatever we wanted it to be. I have had a couple of times when the uptime was bad, but it was caused by a third-party solution. In fact, the Norton antivirus was definitely the worst. Red Hat had nothing to do with it.

Quotes from Members

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

Pros

"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."
"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."
"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."
"The interface is good and straightforward to use."
"The most effective features of Kali Linux include its stability as a Linux operating system, its flexibility in configuring resources such as partitions, its powerful and stable file system, and its multi-user capability, which allows for setting user privileges and rights. Additionally, Kali Linux provides access to a wide range of free and open-source applications for testing and development purposes."
"The solution's most valuable feature is that it is very easy to use."
"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."
"Red Hat Enterprise Linux has given us better insights and allowed us to manage the environment more effectively."
"The deployment is a smooth process."
"Red Hat's greatest asset is its extensive community, which provides valuable support and advice when issues arise."
"The benefits I get from this operating system are that it's secure, easy to use, and stable."
"Everything is just stable and works well."
"Red Hat Enterprise Linux has made significant improvements in terms of storage. You can mount an 18 terabyte file system. It also supports NFS shares and the SIP share for the photos. There have been many features added since RHEL 6. It's more user-friendly and graphical."
"Red Hat Enterprise Linux is most valued for its reliability, as evidenced by my daily use."
"The solution has good availability and is easy to use."
 

Cons

"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"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."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"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."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
"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."
"It isn't hard to patch, but migrating between versions is difficult. We have the the latest version, but the previous version is still working very well. It's hard to leave a working version to upgrade. I would like more AI features, but those will be added to the next version. We are in an AI age, and it's an area where we need to keep pace."
"The price has room for improvement."
"Red Hat should improve its support services, specifically the responsiveness and expertise of its India-based team."
"I feel like it is going all over the place now. Sometimes it is hard to figure out what is going on. I would like more guidance."
"Regarding SELinux, they could make that clearer or make it easier to use."
"Sometimes, when upgrading or migrating systems, there are differences in the repositories of the versions that aren't one-to-one replaceable. For example, there are significant differences in the repositories from version 7 to 8. We needed to upgrade RHEL from version 7 to 8 because it had reached the end of its life. A Postgres database was running on it that used a RHEL 7 package, allowing some database or reporting features. When I upgraded to RHEL 8, it was not in the repository. I needed to install it with some workaround. Of course, it was installed with some minor incompatible dependencies."
"Large application vendors may not have certified RHEL, or they have certified an older version. Most of the large application vendors are unfamiliar with the versioning that RHEL introduced, which I strongly support. They will support a given sub-version up to a point, not realizing that the sub-versions are essentially additive."
"The numerous links to different pages disrupt the flow of information and make it difficult to maintain focus."
 

Pricing and Cost Advice

"I have used the free version."
"I use it free of charge."
"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."
"It is an open-source tool."
"Kali Linux is a free product, and you don't have to pay for a license."
"Kali Linux is open source."
"The tool is open-source."
"We still have a few with one-to-one standard server licensing, but we are utilizing the virtualization host licensing. We license it based on the host, not based on VMs, which is cool. I was very happy that there was certain licensing with SAP to have access to SAP repos. Its cost was the same as the regular one, so I was happy about that."
"They knew we would buy tons of Red Hat Enterprise Linux, so they were a little bit more relaxed. We wanted a thousand licenses, and we could pick those up. We true up. Our license experience has been positive with the exception of having to deal with all of the broken-up accounts, which is as much our fault as anybody's."
"Red Hat Enterprise Linux is quite expensive, particularly its technical support, which can cost $500 per hour."
"The prices are comparable, and good for what is being provided."
"We use open source. We only have a subscription for support."
"It's pretty expensive, but I'm not familiar with the pricing of other vendors for their operating systems. I'd rate it a seven out of ten in terms of pricing. Red Hat Enterprise Linux's main advantage is the support that you get by purchasing their subscriptions."
"Red Hat Enterprise Linux has a yearly subscription cost for the licensing that includes maintenance and support."
"The licensing structure is very convoluted. It's very confusing. We have a Satellite server, and we license it through the Satellite server, but if we didn't, we'd have to buy individual Red Hat licenses. That would be a nightmare to maintain in terms of renewing it every year and things like that."
