We performed a comparison between Splunk and Zabbix based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: In this comparison, Zabbix comes out on top. When compared to Splunk, it is easier to deploy and is open-source.
"The alerting is much better than I anticipated. We don't get as many alerts as I thought we would, but that nobody's fault, it's just the way it is."
"The user interface is really modern. As an end-user, there are a lot of possibilities to tailor the platform to your needs, and that can be done without needing much support from Devo. It's really flexible and modular. The UI is very clean."
"The most valuable feature is definitely the ability that Devo has to ingest data. From the previous SIEM that I came from and helped my company administer, it really was the type of system where data was parsed on ingest. This meant that if you didn't build the parser efficiently or correctly, sometimes that would bring the system to its knees. You'd have a backlog of processing the logs as it was ingesting them."
"Devo helps us to unlock the full power of our data because they have more than 450 parsers, which means that we can ingest pretty much any type of log data."
"The ability to have high performance, high-speed search capability is incredibly important for us. When it comes to doing security analysis, you don't want to be doing is sitting around waiting to get data back while an attacker is sitting on a network, actively attacking it. You need to be able to answer questions quickly. If I see an indicator of attack, I need to be able to rapidly pivot and find data, then analyze it and find more data to answer more questions. You need to be able to do that quickly. If I'm sitting around just waiting to get my first response, then it ends up moving too slow to keep up with the attacker. Devo's speed and performance allows us to query in real-time and keep up with what is actually happening on the network, then respond effectively to events."
"It's very, very versatile."
"The most valuable feature is that it has native MSSP capabilities and maintains perfect data separation. It does all of that in a very easy-to-manage cloud-based solution."
"Devo provides a multi-tenant, cloud-native architecture. This is critical for managed service provider environments or multinational organizations who may have subsidiaries globally. It gives organizations a way to consolidate their data in a single accessible location, yet keep the data separate. This allows for global views and/or isolated views restricted by access controls by company or business unit."
"Its dashboard is valuable. If you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity. If fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."
"The initial setup isn't overly complex."
"The data analysis part is good in Splunk, which is something that I like the most. It is also quite easy to use. Its dashboards, visualizations, and analytics are good."
"The level of robustness on offer is very good."
"It allows us to digest the information, the data, the different data streams, so we can make decisions based upon information that we receive, and it is pretty robust."
"There are quite a lot of things that we find useful. Splunk agents are useful and good. Its UI is quite impressive."
"The integration is seamless with many devices and operating systems."
"The most valuable features are how stable and easy to use Splunk is."
"Zabbix has a roadmap and they are continuously and frequently adding new features."
"The solution is open-source, easy to manage, and user-friendly making it easy for anyone to use."
"The most valuable features in Zabbix are those that help us overcome bottlenecks in CPU usage, as well as reduce memory delay. I know that we have only reached the tip of the iceberg of what Zabbix's features can do for us, and we have not used all of them yet."
"The most valuable feature is the monitoring of virtual machines."
"We have found that Zabbix is more easy to use than other applications."
"There is a problems page that shows us every warning or problem that occurs on our VMs globally. The map screen is also really useful because this is something that was missing. I don't know every other tool in the market. So, I don't know if this is a good point of only Zabbix, or other tools are also doing it, but from my point of view, this is the most useful page that I use, along with the problems page that efficiently lists the problem, recovery time, ending hours, starting hours, and so on."
"The initial setup was very quick. The first time it was long because I didn't know it yet. I was only using Windows. The first time was very difficult because of the operating system."
"The performance and bandwidth are valuable features."
"Where Devo has room for improvement is the data ingestion and parsing. We tend to have to work with the Devo support team to bring on and ingest new sources of data."
"From our experience, the Devo agent needs some work. They built it on top of OS Query's open-source framework. It seems like it wasn't tuned properly to handle a large volume of Windows event logs. In our experience, there would definitely be some room for improvement. A lot of SIEMs on the market have their own agent infrastructure. I think Devo's working towards that, but I think that it needs some improvement as far as keeping up with high-volume environments."
"I would like to have the ability to create more complex dashboards."
"There's room for improvement within the GUI. There is also some room for improvement within the native parsers they support. But I can say that about pretty much any solution in this space."
"The Activeboards feature is not as mature regarding the look and feel. Its functionality is mature, but the look and feel is not there. For example, if you have some data sets and are trying to get some graphics, you cannot change anything. There's just one format for the graphics. You cannot change the size of the font, the font itself, etc."
"We only use the core functionality and one of the reasons for this is that their security operation center needs improvement."
"An admin who is trying to audit user activity usually cannot go beyond a day in the UI. I would like to have access to pages and pages of that data, going back as far as the storage we have, so I could look at every command or search or deletion or anything that a user has run. As an admin, that would really help. Going back just a day in the UI is not going to help, and that means I have to find a different way to do that."
"The overall performance of extraction could be a lot faster, but that's a common problem in this space in general. Also, the stock or default alerting and detecting options could definitely be broader and more all-encompassing. The fact that they're not is why we had to write all our own alerts."
"We had some connections issues with the solution at the beginning."
"You do need a lot of training and certification with this product."
"The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues."
"Splunk is more expensive than other solutions."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
"The implementation and the scanning of the logs can be difficult."
"I would like to see more SIEM functionality and a better ticket tool."
"Splunk can be an expensive solution. Technical support could be improved as well."
"One of the things we don't like is that Zabbix has a license structure with a price that is high compared to the competition. It's very high, for example, compared to something like Microsoft Teams."
"The user interface could be a bit better. They could update it a bit."
"There's a small module of APM, however, it is not an enhanced version. People usually ask for a full-fledged APM solution."
"The reports are not great and should be improved."
"I would like to see a more flexible mobile client, and better HA out of the box."
"There are not too much documentation or manuals. We found the tutorials very easy to understand but do not go deep enough in the use of Zabbix. We need more manuals, proper use, documentation, etc."
"The System Center Operations Manager can be improved."
"The APM monitoring has room for improvement, although I hear that the new 5.2 version has some improvements in that area, and I'd like to give that a go. I would like to see a few more templates out there for different styles of monitoring. I use the Grafana interface for reporting. I would also like it to have an out-of-the-box ability to email reports. You can create reports, but to be able to email those reports would be really helpful. I've got users who are not interested in logging in and generating a report. They want it all pre-canned and sent to an email address. It would also be really handy if we could pin certain reports up onto platforms such as Teams or SharePoint. A GUI for the proxy server would be cool to have for debugging purposes and for the support teams to have a look at, but I don't know whether that's really feasible to do. I get enough from the log files themselves."
