Manager at Accenture company

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.

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

"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."

"The tools available in Kali Linux are incredibly effective for conducting security assessments."

"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 solution's most valuable feature is that it is very easy to use."

"The solution's stability is very good."

"Additionally, it now includes comprehensive migration analytics and reporting capabilities."

"The most valuable feature of Kali Linux is the attack it performs using a CVE script that's already on the internet."

"The interface is good and straightforward to use."

More Kali Linux pros

"I prefer it to Windows because of the level of configuration, level of control, and the ability to see the performance of processes on a given system. I prefer the control over logging and the ability that logging gives you to investigate a problem."

"I like most of the features. I like its stability. I like its views. It provides a very stable environment."

"The biggest benefit is from a security standpoint. As the product progresses and they come up with new versions, the new security features are addressing vulnerabilities. From that perspective, it has worked well."

"Copious documentation is probably the best feature of the solution."

"The support from Red Hat is valuable."

"Red Hat's support and the latest versions offer significant advantages, including efficient resource utilization with Red Hat Enterprise Linux, allowing us to run more workloads with fewer resources."

"The GUI for network adapters and built-in tools provided by RHEL, such as the Mozilla browser, have been valuable. Since they come built-in, it saves the time of having to install them, and you have everything necessary with the installation itself."

"It is consistent. It is geared toward security."

More Red Hat Enterprise Linux (RHEL) pros

Cons

"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."

"The product should improve its security features."

"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 tool is already stable and well-developed, so there's minimal feedback for enhancement or change. However, it should improve security, which is crucial, especially with the increasing use of Kali Linux in cloud 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."

"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."

"The product should integrate AI and GPT capabilities."

More Kali Linux cons

"It is constantly improving. It is important to continue to improve."

"The deployment learning curve for Red Hat Enterprise Linux could be more user-friendly."

"The solution is moving away from CentOS and there are growing pains from the customer's perspective."

"One challenge we've faced is with databases. Configuring and implementing DBs is much easier in non-Red Hat Enterprise Linux systems, especially in Microsoft."

"I don't find Red Hat Enterprise Linux's security features to be good. They have many vulnerabilities that haven't been fixed for many years."

"I would like a more straightforward process for extending file systems without the need to write all the names of volume groups and logical volumes, to simplify automation."

"It is a bit on the pricier side. However, due to the stability and support that they provide to my management and me, we really don't see a reason to choose another way to go. It is hard to get good support."

"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."

More Red Hat Enterprise Linux (RHEL) cons

Pricing and Cost Advice

"The tool is open-source."

"The price is good because Kali Linux already provides a good bundle of tools."

"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."

"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."

"Kali Linux is a free product, and you don't have to pay for a license."

"Kali Linux is open source."

More Kali Linux pricing and cost advice

"Our client has a direct subscription to Red Hat."

"The combined cost of implementing in hybrid and cloud environments to fulfill all our client's needs can be considerable."

"Red Hat Enterprise Linux is expensive, particularly for governments operating with limited budgets."

"Red Hat Enterprise Linux is suitably priced with various support tiers to match organizational needs and environments."

"Red Hat Enterprise Linux is only affordable for large organizations."

"We are an educational institution and as such, what we pay is less than the average company."

"It is more expensive than other vendors in terms of pricing and licensing, but because of its stability, I have to go with it."

"We can always ask for Red Hat Enterprise Linux to be less expensive but when we compare it to other options, there are savings in the long run."
