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.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"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."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"I am very proud of how very stable the solution is."
"Graylog is worth the given effort."
"Feature-wise or from the end user perspective, Graylog is just great."
"The product does all the things it must do very well."
"I like the simplicity of the solution, the fact that it's open source and user friendly."
"We use the solution because it is granular."
"Our primary use case for this solution is detecting issues to provide customers with information."
"The initial setup was very simple and straightforward, according to our security team."
"I have made use of technical support and am certainly very satisfied with them."
"The user interface is very good."
"The log management has helped to improve my organization."
"It's one of the easiest products. It's very simple to use."
"ManageEngine EventLog Analyzer was a lower-cost alternative, and it was easier to install and manage."
"The features of Splunk Enterprise Security that I appreciate the most include the SPL search."
"It has a big user base, so the community is useful."
"Great platform with user-friendly interface and GUI."
"They are a good partner for Google Cloud. It provides great visibility, threat detection, and proactive mitigation of risks for our mutual consumers."
"The solution's most valuable feature is the aggregation of all the logs in one place, using enterprise securities built-in or ESCU use cases to find them."
"I would strongly recommend this product, as it would be very beneficial for service operations and management."
"Splunk Enterprise Security has helped greatly improve the organization's business resilience."
"The solution helped reduce our alert volume."
 

Cons

"Dashboards, stream alerts and parsing could be improved."
"Lacks sufficient documentation."
"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-"
"For Python developers, 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."
"The alerting system could be more flexible."
"The initial setup was really complex because I did it myself."
"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."
"The solution should improve on its log capturing capabilities, the authentication, when a person logs onto a network device."
"It may not be as easy to use as Splunk."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"The product does not have certain advantages, especially the correlation tools. It was not working as per our expectations."
"The scalability is limited."
"I would like to see more detailed reports."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"Our two main complaints are about the difficulty of the initial setup and the licensing model."
"Splunk Enterprise Security offers a vast amount of information to learn and comprehend, resulting in a challenging initial learning curve."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."
"Areas of Splunk Enterprise Security that could be improved include the need for training and certifications. We are planning to do certifications, and there are many features, such as risk-based score and score detection, where the current training doesn't provide visibility to the analyst."
"It currently has limited default rules and customizations. If they can concentrate more on the compliance part and the security information part, it would be helpful. The platform part is good, but it requires many features from the security aspect."
"Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."
"One issue is that we are getting a lot of false positives. We are trying to reduce them by customizing the default rules, changing thresholds, and using white-listing and black-listing. It's getting better and better as a result. But they need to build components that would reduce the false positives."
"Better education for users would be beneficial as they often don't know what they don't know or how to look for certain features."
 

Pricing and Cost Advice

"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."
"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."
"I use the free version of Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
"We are using the free version of the product. However, the paid version is expensive."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Having paid official support is wise for projects."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"There is a yearly subscription for the solution."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."

"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"The subscription is monthly."
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"Splunk is costly but it’s worth it due to the high-end features."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."
"Be upfront about your needs and expectations. Splunk is great to work with."
"The solution is costly."
