Gabriel R. Sousa - PeerSpot reviewer
Consultor De Informação Plena at Protivity Brasil
Centralized logging has provided full security visibility and supports faster incident investigations
I think one of the positive points Graylog Enterprise offers is this centralization of logs, which greatly facilitates investigation work. Another point is its ability to perform searches, apply filters, and run queries so that you can look for a specific event, user, or IP. I think Graylog Enterprise brought efficiency gains because when you run a search or do some research, you can save it, so you do not need to enter the query again; you just retrieve what is already saved. I think the main point regarding Graylog Enterprise features is that it helps a lot in event analysis and identification because it brings in a lot of logs and a lot of information, so you can access all the information about the alert there. I believe Graylog Enterprise's AI features are very good, allowing you to use AI to run specific searches, which brings a lot of results. Regarding the AI features of Graylog Enterprise, I did not use them in such depth as to accurately evaluate their reliability, but I believe that AI can help speed up analysis and identify some suspicious patterns, though it is important that the result is always validated by an analyst.

Has ensured compliance by centralizing log data and supporting secure connections
We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"Graylog Enterprise as a SIEM is fantastic for receiving logs, and the integrations with external connectors also add many features."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"The solution's most valuable feature is its new interface."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"The best features that Graylog Enterprise offers in my experience are the indexing capabilities and the search and filtering functionality, as they present several innovative resources that truly help in defining parameters and understanding behavior."
"Collaboration between teams has improved because we can share the ID of a specific log with the support team, infrastructure team, architecture team, or development team, allowing everyone to handle the same information and have access to the same environment."
"Message forwarding through the in-built module."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng has a separate config file in addition to the core configuration."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
 

Cons

"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"Graylog can improve the index rotation as it's quite a complex solution."
"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."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"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 biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is always the potential for additional integration and protocol extensions."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
 

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."
"It's an open-source solution that can be used free of charge."
"I use the free version of Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Syslog-ng is a free open-source solution."
"Syslog-ng is open-source."
