Robust event correlation enhances operations, yet integration scope can broaden for seamless data handling
The features and capabilities of Graylog that we have found most valuable are related to its basis on open search, which was ElasticSearch. We appreciate being able to integrate custom feeds and do custom parsers, and to be able to do some of the correlation on it. That all works effectively. The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm. We use it for investigating problems and problem management. We throw all the information at it, we have it alerting for certain conditions, but generally we use it for deep diving into issues as needed.

Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

Quotes from Members

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

Pros

"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"Message forwarding through the in-built module."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"The product is scalable. The solution is stable."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"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."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Technical support is good overall."
"The interface is good."
"The flexibility is good in terms of pulling log files."
"I think it's a very stable product that provides much more visibility than the other product."
"We've found the solution to be scalable."
"This is a good tool to have because it gives you the ability to track what is currently happening in your environment."
"It has improved my efficiency."
"The query search and log fetching are really helpful in IBM Security QRadar when compared to other tools."
 

Cons

"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."
"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-"
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"Dashboards, stream alerts and parsing could be improved."
"There should be some user groups and an auto sign-in feature.​"
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"We need more features in order to create rules to detect or to meet some requirements for other areas, for example, catching the event from other authentication tools."
"The costing part could be improved."
"A lot of information that we receive for the devices is IP-based, but it would help if we could have a default dashboard in which we can add more details about the assets for which we are receiving the information. For example, if it is a Windows or Linux device, we only get the IP for that particular device. We don't really get the name and other details of that particular device. For that, you have to drill down into your own asset management system. It would be good to have a place where we can probably add this information so that we don't have to look into other tools."
"The usability of interfaces could be improved."
"The solution lacks some maturity."
"What needs to be improved in IBM QRadar User Behavior Analytics is the user experience. It's not optimal. Some screens are a bit clunky. The solution needs to be more user-friendly."
"The playbook guide which specifies the rules for security use cases needs to be provided to support in case the organization needs help."
"The IBM support can be better."
 

Pricing and Cost Advice

"It's an open-source solution that can be used free of charge."
"We're using the Community edition."
"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."
"Having paid official support is wise for projects."
"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."
"I am using a community edition. I have not looked at the enterprise offering from 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."
"It's too expensive."
"The cost of this product is expensive."
"QRadar UBA's price is a little more than street price and could be reduced."
"The maintenance costs are high."
"It is cheaper than ArcSight."
"It's very expensive but it fits our budget."
"The pricing is higher but cheaper than others and there are no additional costs."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
