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.

Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.

Quotes from Members

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

Pros

"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."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"Graylog is very handy."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"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."
"This is a distributed application, meaning that a customer can stack small and then scale it so that they can expand pretty effectively. You can use, basically, the same product in an SMB or a large enterprise."
"It can analyze event logs, event security, and give a good consult."
"An engineer can live-monitor all the flow happening in real-time. This would help us a lot while investigating a case, and it would even help us with preventive actions."
"Technical support is good overall."
"It's built around Red Hat Linux, which is highly robust."
"This solution has excellent security analytics."
"Overall a great solution."
"I think it's a very stable product that provides much more visibility than the other product."
 

Cons

"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"More customization is always useful."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"With technical support, you are on your own without an enterprise license."
"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-"
"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."
"There should be some user groups and an auto sign-in feature.​"
"The solution should enhance its capabilities of UEBA and AI/ML tech modeling."
"I would like for Yara to be supported by all components."
"The playbook guide which specifies the rules for security use cases needs to be provided to support in case the organization needs help."
"Before we didn't have any security issues but recently a few of the user emails were hacked. We had to actually recreate their emails for them."
"The product does not have a team for investigating malware."
"The features that could be improved include the licensing model and the dashboards and all those presentations. Overall, the user experience part can be improved."
"IBM QRadar Advisor with Watson could be more user-friendly. You need some skills and understanding of what you're looking at, especially if you're going to draw down specific information."
"Technical support really needs to be improved. Right now, they aren't where they need to be at all."
 

Pricing and Cost Advice

"We're using the Community edition."
"Having paid official support is wise for projects."
"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."
"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 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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We are using the free version of the product. However, the paid version is expensive."
"I use the free version of Graylog."
"There is a license required for this solution."
"IBM has subscriptions plans that run for one year."
"This price is a little high, so it's an expensive product."
"It could be cheaper, but the value itself is far more important for us than the price. Typically, our clients have yearly subscriptions."
"We pay approximately $40,000 to use the solution annually. This solution is a lot less expensive than Splunk."
"The license is not subscription-based."
"Go through a vulnerability assessment review for price breaks. A virtualized solution will also cut down on cost."
"It's too expensive."
