Log analysis has become clearer and faster but visualization and extensibility still need work
The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"Message forwarding through the in-built module."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Open source and user friendly."
"I am very proud of how very stable the solution is."
"The user interface is very good."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"It's one of the easiest products. It's very simple to use."
"I have made use of technical support and am certainly very satisfied with them."
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"The tool's reports show activities."
"What I found most useful in ManageEngine EventLog Analyzer is its integration with other ManageEngine applications. It seamlessly integrates throughout the ManageEngine suite, and that's beneficial. I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"It is stable."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"Splunk Enterprise Security performs 80% of our work on its own; we just have to do the remaining 20%, which gives us the freedom to explore and detect threats more effectively."
"While it might be an initial upfront investment on data onboarding, it's going to be something that makes your life incredibly easy once you get beyond that point."
"You can use it to gather syslog messages from anything."
"I really appreciate the all-integrated SIEM feature of Splunk Enterprise Security, which serves as a one-stop shop to get all security tasks done."
"It's standardized and easy to use, so you don't have to have a lot of top-tier analysts to do the same job."
"The solution's most valuable feature is its data modeling."
"Out-of-the-box, it seems very powerful."
 

Cons

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"The problem was with the complexity and the cost to add extensions."
"There are many other applications in the market that influenced my rating reduction."
"More customization is always useful."
"With technical support, you are on your own without an enterprise license."
"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"The scalability is limited."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"Support could improve to make the solution better."
"Last month, we faced an issue with a Hawaiian VPN user activity."
"The first tier of customer service and support is not great."
"It may not be as easy to use as Splunk."
"The solution should improve on its log capturing capabilities."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"The tool itself is very difficult to configure. It's great for its number of inputs, for the different types of systems devices, and things that it could collect information from. To actually make good use of it, you need a fairly dedicated team of people that have some reasonably good programming or modeling skills to be able to do the things that you need to do with it. Whereas a lot of the other tools are better packaged for that, and so require a lot less training and a lot less dedication."
"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."
"Could be more user friendly."
"The glass table feature does not perform as expected."
"There can be a bit of complexity around some fields during the initial setup."
"My biggest struggle with Splunk in general is memorizing all the commands. If I want to know which users have logged in between certain hours, I cannot write that query out. It would be helpful to have AI so that I can explain in simple terms what I want and then the search gives that back to me. I am waiting for that."
"The user interface feels clunky to navigate and interact with in Splunk Enterprise Security compared to other case management solutions where it feels easier to use at a high level."
"It is very complicated to write your own correlation rules without the help of Splunk support."
 

Pricing and Cost Advice

"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"There is a yearly subscription for the solution."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"The Splunk licensing is high."
"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."
"Splunk Enterprise Security is expensive but the solution is equipped with a lot of features."
"It is not cheap."
"Splunk is expensive based on our current requirements, but it's obviously worth what we pay."
"I think that most of the monitoring solutions are expensive."
"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
