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

"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"The solution's most valuable feature is its new interface."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The AI Engine can take an event and correlate it into something else giving us meaningful context regarding what is going on. We integrated it in with our ticketing system, so if an alarm fires, it raises a ticket in our system."
"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."
"The GUI is very intuitive and the solution has good integration."
"In general, the visibility of events and advanced analysis of events are good."
"We take in around 750 million logs a day. We have a lot of products and that would be a lot of different panes of glass that we would have to look through otherwise. By centralizing, we can triage and take steps much more quickly than if we tried to man that many interfaces that come with the products."
"It has allowed us to dive deeper into our network and figure out what is going on by parsing logs properly and being able to reduce the time it takes to work cases down from seven days to approximately two days."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
 

Cons

"More customization is always useful."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"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."
"Lacks sufficient documentation."
"I would like to see some kind of visualization included in Graylog."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"There are many other applications in the market that influenced my rating reduction."
"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 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."
"Appliance-based setups can sometimes pose scalability issues"
"Scalability-wise, it's not that great."
"Sometimes, the tool fails to get the correlated events that triggered the alerts."
"The SOAR capabilities need improvements as they currently require programming knowledge."
"I don't think the cloud model in LogRhythm is developed enough."
"I think there is room for improvement because the system is still running on the Windows Server platform. The problem with running on Windows is that it is not that good for scaling and providing for big deployment environments."
"Sometimes the error-logging is not altogether helpful. For example, on an upgrade, a systems data processor, a Windows box, was throwing an error code like 1083. Then it just stopped and it died right out of the installer and nobody looked. We searched through Google and what it means is the Windows Firewall wasn't turned on so that it could create a rule for the product. Why wouldn't they bubble up that description so that I wouldn't have to call support and I could just know, "Okay, the firewall wasn't turned on. Turn it back on. Re-run the installer and keep going.""
 

Pricing and Cost Advice

"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"Having paid official support is wise for projects."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"I use the free version of Graylog."
"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."
"LogRhythm's licensing is based on MPS. There are some add-on features like advanced UEBA, the cloud component for advanced UEBA, and SIEM."
"NextGen SIEM's pricing is moderate."
"I give the price a six out of ten."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"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."
