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.

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

"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."

"Feature-wise or from the end user perspective, Graylog is just great."

"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."

"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."

"Troubleshooting is straightforward with Graylog Enterprise."

"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."

"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."

"The solution's most valuable feature is its new interface."

More Graylog Enterprise pros

"Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task."

"The ability to ingest different log types from many different products in our environment is most valuable."

"The most valuable features in Splunk are the search function and the ability to run selected session reports. The session reports are important because I can use them to see what is going on in our environment weekly. Additionally, we can use the graph to see how often that particular event is happening."

"We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used."

"Its dashboard is valuable. If you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity. If fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."

"The most valuable feature is the log aggregation, being able to scan through all of the logs."

"Positive features include replication capabilities, software development kits, and the architecture."

"We can do things in minutes instead of days."

More Splunk Enterprise Security pros

Cons

"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."

"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."

"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."

"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."

"Its scalability gets complicated when we have to update or edit multiple nodes."

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."

"The support from the Graylog community is helpful, but they can do better."

"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."

More Graylog Enterprise cons

"The high cost of Splunk Enterprise Security prevented us from using its full capabilities."

"Its reporting can be improved."

"I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets."

"We haven't saved any money with Splunk Enterprise Security. Instead, we have spent excess of the budget on this with unexpected costs."

"It does not give us permission to implement on-premise so we implement them on the cloud."

"Pricing is one factor that hurts everybody on the market; the client, the reseller, everybody that touches it. Only Splunk makes money."

"On-premises scaling of the solution is a bit more limited than it is on the cloud."

"Splunk Enterprise Security is great but can have some frustration points. It can sometimes be slower to use."

Pricing and Cost Advice

"I use the free version of Graylog."

"We're using the Community edition."

"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."

"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 am using a community edition. I have not looked at the enterprise offering from Graylog."

"You get a lot out-of-the-box with the non-enterprise version, so give it a try first."

"Consider Enterprise support if you have atypical needs or setup requirements."

"We are using the free version of the product. However, the paid version is expensive."

More Graylog Enterprise pricing and cost advice

"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."

"It's a yearly subscription."

"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."

"The price is comparable."

"Some of the insights that we have obtained as a part of using Splunk have greatly helped us in increasing our revenue in terms of selling our products."

"This product could use better pricing in general."

"It's definitely worth it."

"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
