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.

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

"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"Graylog is very handy."
"Message forwarding through the in-built module."
"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."
"Open source and user friendly."
"The dashboard is easy to use and easy to understand what's going on and what the alerts mean."
"The QNI feature is the one I am very interested in, and I have also been interested in Watson. From the log analysis and the security perspective, we are able to dive deep into any of the logs and anomalies."
"What's most valuable in IBM QRadar User Behavior Analytics is its higher availability than other tools."
"The most valuable feature of the solution is its ability to rectify a situation involving any anomalies expeditiously."
"QRadar shows very effective correlations. If you combine all the logins plus user behavior and the current intelligence, it gives a very good correlation for business. I think it reduces the false positives in user activity monitoring because there is a lot of social information to correlate with other data."
"It is a pretty solid product for the type that it is representing. It is a CM solution as compared to Splunk or ArcSight from HP. It is also user friendly. It comes with some internal AI as well, in which it automatically maps multiple lots from unrelated devices and makes a smart decision to link them back and create an offense based on that. It is a smart tool."
"The feature that I have found most valuable is how it monitors the real network. That is its leading security feature."
"QRadar UBA's most valuable feature is the risk rating of users depending on their behavior."
 

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."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"Dashboards, stream alerts and parsing could be improved."
"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."
"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."
"There should be some user groups and an auto sign-in feature.​"
"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."
"You can scale IBM QRadar User Behavior Analytics, but it has room for improvement."
"IBM Security QRadar's mobile app lags behind with limited offensive viewing and no push alerts for high-severity incidents."
"The product needs to improve its GUI."
"I don't look at only the features and benefits; I also look at the price. It is a bit expensive when compared with other solutions. It is expensive for specific deployment topologies, and the decision-makers go for alternatives like ArcSight. It should also have more AI features or capabilities for better threat intelligence. The more it uses machine learning, the better would be the dashboard, analytics, and other things."
"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 AI engine could be smarter."
"IBM QRadar has outdated technology, and this is its area for improvement. When you try to implement an analytic expression, it's not updated. The solution doesn't support newer technologies, and it doesn't update regularly. For example, around the world, others implement new technologies, while IBM updates later than others."
"The AQL queries could be better."
 

Pricing and Cost Advice

"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."
"We're using the Community edition."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"I use the free version of Graylog."
"Having paid official support is wise for projects."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"It is cheaper than ArcSight."
"Licensing can be costly depending on your architecture."
"The pricing is always fine."
"Only enterprise businesses can afford the tool."
"It is costlier as compared to the other alternatives available in the market."
"IBM QRadar User Behavior Analytics is an application framework and you can install many applications without any additional costs."
"I think that the price is fair, but we can always say that the price could be cheaper."
"The price of this solution is a little bit expensive, so if it were cheaper then it would help."
