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.
HarshBhardiya - PeerSpot reviewer

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

"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."
"I am very proud of how very stable the solution is."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Message forwarding through the in-built module."
"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."
"Open source and user friendly."
"The query search and log fetching are really helpful in IBM Security QRadar when compared to other tools."
"IBM Security QRadar's AI and machine learning capabilities for threat detection and response are exceptional, and Q Site is used to create panels and visualizations of software development processes."
"The most valuable features are all the implementations, the plug-ins, and the User Behavior Analytics (UBA)."
"In terms of the most valuable features, the log collections and log processing mechanisms are good. They have good dashboards."
"It is the core of our entire SOX."
"Log correlation is very useful for processing alerts. It serves to follow up alerts in real-time, building an entire workflow."
"It has a lot of good correlation rules. From a customer's point of view, it is one of the best solutions because you don't need to create correlation rules from scratch. You just review them and customize them as you want."
"The most valuable feature is the integration with the GRD, for banking."
 

Cons

"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"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."
"Graylog can improve the index rotation as it's quite a complex solution."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"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."
"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."
"They should introduce some automation into the product."
"The product needs to improve its GUI."
"IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas."
"We sometimes get an error about the hard drive. Approximately once in two months, we can't find the logs, and they go missing, which is a terrible issue. We are getting support for this issue from our support company."
"It needs more resilience and functionality."
"SOAR is what is expected the most from QRadar. They have something called SOAR Resilient, and it would be great if that gets induced in SIEM. IBM QRadar (as well as McAfee ESM) should have analytics platform integration. Currently, SIEMs don't have full-fledged integration with analytics where we are able to dump our data in SIEM, and the same data can be called from different analytics applications. We should be able to bring this data to a platform like Hadoop for big data and run the analytics there. Currently, people are seeing the past data and taking some actions in the present, but when it comes to analytics, there should be futuristic data where you can predict something out of your present and past data. Apart from that, I would like to see a full-fledged ITSM tool in QRadar. It sometimes has some technical issues that need to be checked. It requires a dedicated QRadar engineer to completely manage it. It has different module sets, such as event collector and event processor, and some technical glitches come in between. It takes the log but doesn't exactly process it in the way we want."
"The AQL queries could 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."
"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."
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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."
"QRadar UBA's price is a little more than street price and could be reduced."
"It is expensive. It is not a product that I can provide for SMBs. It is a program that I can only provide for really large enterprises."
"The product is expensive. We have purchased the perpetual license, but we pay for the support."
"The solution has a licensing model that is based on events per second so it scales to need and budget."
"The solution is costly and the price differs depending on the vendor you use."
"It's not expensive for the resources that it gives you."
"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."
"think the pricing is quite flexible."
