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.

Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

Quotes from Members

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

Pros

"Open source and user friendly."
"The product is scalable. The solution is stable."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"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."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Real-time UDP/GELF logging and full text-based searching."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"Technical support is very helpful and responsive."
"The ability to drill down and pivot from an event is one of the biggest advantage the product has compared to other things that I have seen in the market."
"It's very easy to create the correlation rules with LogRhythm, and there are some advanced features like SIEM and UEBA, which are also very valuable."
"The artificial intelligence engine."
"LogRhythm's GUI is easy to explore. We also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"The Web Console is my favorite. It enables me, at a glance, to see the health of the environments."
"LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis."
 

Cons

"The problem was with the complexity and the cost to add extensions."
"I would like to see some kind of visualization included in Graylog."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"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."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"There is room for improvement with separate running sources or better integration."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"Only area I can think of to improve on is the proof reading and using the guides before releasing them. Out the the 20+ guides I used one had issues with wrong information in it."
"The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources."
"It's not easy for someone new to the solution."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"I would like it to do a lot of the automation (which I still need to learn more about), because I am essentially a one man shop doing all the jobs. I'd like for it to be able to do more for me."
"In the next release, I would certainly like to see more HIPAA compliance. I would also like to see more integration with Palo Alto Networks, particularly their Traps, which is their endpoint solution."
 

Pricing and Cost Advice

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We're using the Community edition."
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We are using the free version of the product. However, the paid version is expensive."
"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."
"It's an open-source solution that can be used free of charge."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"In the context of our country, the price of this solution is too high."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
