Real-time analysis, easy setup, and open source
We stopped using it for analytics because of its price, and at the moment, we are using it mostly for log centralization. If you use it with high traffic for analytical purposes, as well as for the logs, the infrastructure costs are unbelievable. Graylog is a great product backed by Elasticsearch as the storage and query engine. It is just an interface on top of Elasticsearch and some Elasticsearch management. The indexes that are kept in Elasticsearch are managed by Graylog software. Elasticsearch is a decent product, but it's very infrastructure-heavy. It requires lots of resources, and if you make a mistake with provisioning, you are likely to not get a cluster back. We had a couple of outages like that, and we hated that. So, we ended up over-provisioning resources just to avoid such situations from happening. If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much. That may be my Norwegian take on it, but the engineering resources are expensive. It's better to just provision the infrastructure. Overall, the product is great, and the features are just fine, but the infrastructure cost is what is killing it. The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic. I'm not sure if they can improve the infrastructure cost with the way Elasticsearch is. If they keep using Elasticsearch, maybe there are some opportunities there, or they can support other backends with cheaper storage. They could have a different backend to replace Elasticsearch or do some tweaks to Elasticsearch to reduce the costs. There could be partial parsing of logs or parsing on demand so that when you write data through Graylog to Elasticsearch, it doesn't need to crunch in every detail requiring that much CPU.

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"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."
"I like the correlation and the alerting."
"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."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"LogRhythm NextGen SIEM covers all our primary security analysis needs. It makes it easier for us to analyze threats and improves our response times. It's a versatile platform that performs queries fast compared to other SIEM solutions."
"It supports most standard log sources."
"The ability for me to go into the Web UI, and just learn what's going on in my environment."
"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."
"Our clients enjoy having one dashboard to monitor their environments in real time."
"NextGen SIEM's best feature is how it presents logs."
"It's reliable and the performance is good."
"Automations are very valuable. It provides the ability to automate some of our small use cases. The ability to integrate with other products that use an API is also very useful. LogRhythm has a plugin for it that we can connect and start to move down towards the path of a single pane of glass instead of having multiple or different tools."
 

Cons

"More customization is always useful."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"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."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Graylog can improve the index rotation as it's quite a complex solution."
"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."
"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."
"I would like to suggest that they should improve their usage of third party tools for making dashboards and reports. If they would create their own tools for dashboard and report, it would be much better in terms of security purposes."
"I don't think the cloud model in LogRhythm is developed enough."
"The built-in functionality of the solution for NDR, SOAR, SIEM, and EDS has room for improvement."
"The solution is likely not the best option for a smaller organization."
"I face stability issues every quarter that necessitate corrective maintenance."
"The pricing is the only problem."
"The installation was a bit complex because we are running a virtual infrastructure."
"We do about 750 million a day and some days we do 715 million. Some days we do 820 million or 1.2 billion. But there's no way to drill in and find out: "Where did I get 400,000 extra logs today?" What was going on in my environment that I was able to absorb that peak? I have no way to identify it without running reports, which will produce a long-running PDF that I have to somehow compare to another long-running PDF... I would like to see like profiling behavior awareness around systems like they've been gunned to do around users with UEBA."
 

Pricing and Cost Advice

"I use the free version of Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"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."
"It's an open-source solution that can be used free of charge."
"If you want something that works and do not have the money for Splunk or QRadar, take 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.​"
"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."
"Everything is expensive with LogRhythm, and you don't get anything for free."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"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."
"I would recommend talking to the rep. That's the biggest thing because they will know what questions to ask."
"The license cost is around $10 per MPS."
"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."
