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.

Quotes from Members

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

Pros

"The ability to write custom alerts is key to information security and compliance."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"I am very proud of how very stable the solution is."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"I like the simplicity of the solution, the fact that it's open source and user friendly."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"ManageEngine EventLog Analyzer is useful for log and alert correlation and is a full-function SIEM solution."
"ManageEngine EventLog Analyzer was a lower-cost alternative, and it was easier to install and manage."
"Our primary use case for this solution is detecting issues to provide customers with information."
"The user interface is very good."
"It is stable."
"The tool's reports show activities."
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"The support system is very good."
 

Cons

"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much."
"More customization is always useful."
"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 support from the Graylog community is helpful, but they can do better."
"The problem was with the complexity and the cost to add extensions."
"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."
"Graylog Enterprise performs well overall; however, the UI could be improved because the SOC team creates multiple dashboards based on their use cases, and creating dashboards is complex."
"There's a lot to improve in terms of connectivity. Currently, we're utilizing it across various infrastructures and environments, including others' cloud. However, connecting it to our infrastructure and integrating it with some of our SMAX solutions poses difficulties."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"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."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"I would like to see more detailed reports."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution 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."
"We are using the free version of the product. However, the paid version is expensive."
"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."
"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."
"​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.​"
"I am using a community edition. I have not looked at the enterprise offering from Graylog."

"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
