Ritik Varshney - PeerSpot reviewer
Enhanced data streaming with reliable features and good analytics
Apache Kafka on Confluent Cloud provides an enhanced level of reliability and resources compared to Apache Kafka alone. It offers more features which are beneficial for our clients, including cluster linking, schema registry, error handling, and dead-letter queues. It significantly improves customer and publisher satisfaction, especially with topic integration and data streaming.
Rohit Srivastava - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"Overall, I think it's a good experience. Apache Kafka can be quite complex and difficult to maintain on your own, so using Apache Kafka on Confluent Cloud makes it much easier to use it without worrying about setup and maintenance."
"Kafka and Confluent Cloud have proven to be cost-effective, especially when compared to other tools. In a recent BI integration program over the past year, we assessed multiple use cases spanning ship-to-shore and various Azure integrations. Our findings revealed that Confluent Kafka performed exceptionally well, standing out alongside Genesys and Azure Event Hubs. While these three are top contenders, the choice among other tools depends on the specific use case and project requirements. The customer initially used tools like SMQs, FITRA, and Stream for real-time data processing. However, after our recommendation, Confluent Cloud proved to be a superior choice, capable of replacing these three tools and simplifying their data infrastructure. This shift to a single tool, Confluent Cloud, streamlined their operations, making maintenance and management more efficient for their internal projects."
"Kafka provides handy properties that allow us to directly configure the data, whether to keep it or discard it after use."
"In case of huge transactions on the web or mobile apps, it helps you capture real-time data and analyze it."
"The product's installation phase is pretty straightforward for us since we know how to use it."
"The state-saving feature is very much appreciated. It allows me to rewind a certain process if I see an error and then reprocess it."
"Apache Kafka on Confluent Cloud is more reliable and frequent to use compared to Apache Kafka."
"Confluent Cloud handles data volume pretty well."
"We use the product for open-source intelligence and identifying vulnerabilities."
"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."
"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 tools available in Kali Linux are incredibly effective for conducting security assessments."
"The interface is good and straightforward 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."
"Additionally, it now includes comprehensive migration analytics and reporting capabilities."
 

Cons

"Some areas for improvement in Apache Kafka on Confluent Cloud include issues faced during migration with Kubernetes pods."
"Regarding real-time data usage, there were challenges with CDC (Change Data Capture) integrations. Specifically, with PyTRAN, we encountered difficulties. We recommended using our on-premises Kaspersky as an alternative to PyTRAN for that specific use case due to issues with CDC store configuration and log reading challenges with the iton components."
"The solution is expensive."
"There's one thing that's a common use case, but I don't know why it's not covered in Kafka. When a message comes in, and another message with the same key arrives, the first version should be deleted automatically."
"There are some premium connectors, for example, available in Confluent, which you cannot access in the marketplace, so there are some limitations."
"The administration port could be more extensive."
"Maybe in terms of Apache Kafka's integration with other Microsoft tools, our company faced some challenges."
"There could be an in-built feature for data analysis."
"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"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."
"The tool is slightly difficult to learn."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"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."
"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."
 

Pricing and Cost Advice

"I think the pricing is fair, but Confluent requires a little bit more thinking because the price can go up really quickly when it comes to premium connectors."
"I consider that the product's price falls under the middle range category."
"Regarding pricing, Apache Kafka on Confluent Cloud is not a cheap tool. The right use case would justify the cost. It might make sense if you have a high volume of data that you can leverage to generate value for the business. But if you don't have those requirements, there are likely cheaper solutions you could use instead."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"The price is good because Kali Linux already provides a good bundle of tools."
"I use it free of charge."
"Kali Linux is a free product, and you don't have to pay for a license."
"I have used the free version."
"Kali Linux is open source."
"The licensing fee is expensive compared to other products."
"It is an open-source tool."
