NC
Security Officer at JSC "Moldtelecom" S.A.
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

"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"Graylog is very handy."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"Troubleshooting is straightforward with Graylog Enterprise."
"The ability to write custom alerts is key to information security and compliance."
"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."
"Alarms are the most valuable feature. We also like the dashboard and how things are at your fingertips. The fact that we can now edit the report templates is going to be a great thing."
"SOAR is integrated with the dashboard that we use for threat management. Because it's all integrated, it is useful for us when we deploy something on-prem."
"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."
"The ability for me to go into the Web UI, and just learn what's going on in my environment."
"The initial setup is pretty easy."
"Even other products we have that feed into it, instead of having to watch all of them we only have to watch one. For example, we have CrowdStrike, so instead of having to pay attention that solution - because their dashboard doesn't really pop when an alarm comes up - we can see issues with the red on the LogRhythm alarm. That is very nice."
"It supports most standard log sources."
 

Cons

"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."
"More customization is always useful."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"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."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Dashboards, stream alerts and parsing could be improved."
"With technical support, you are on your own without an enterprise license."
"The initial setup is complex. We are using a LogRhythm partner, at least for the first three years, to help with the monitoring and the deployment of it. We are not a big enough environment where we have people that we can dedicate to it right now."
"In terms of blind spots, we are looking for more improvements since we don't have visibility over everything."
"It should have some more message monitoring features. It can also have some free message monitoring tools."
"When we had version 7.2.6, there were a lot of issues deploying that version and with the indexing. The indexer was unstable. So, we were not able to use the platform when we were on that version until we were able to upgrade to 7.3.4."
"The main problem I have with LogRhythm SIEM is its stability; the solution is not stable."
"There are other security technologies outside of this SIEM that should be inside of this SIEM. I can see in their roadmap that they're trying to address a lot of these things, and have these technologies built into the solution, because there is no point in going to another vendor or opening up a second window to obtain the data that you need."
"The SOAR capabilities need improvements as they currently require programming knowledge."
"I think they probably need to, because a lot of companies are having this cloud-first strategy, where anything that's new has to go into the cloud for some reason."
 

Pricing and Cost Advice

"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"In the context of our country, the price of this solution is too high."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"We did a five-year agreement. We pay close to a quarter of a million dollars for our solution."
"It is a very cost-effective solution."
"The license cost is around $10 per MPS."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
