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.

A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"The product is scalable. The solution is stable."
"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 build is stable and requires little maintenance, even compared to some extremely expensive products."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"Graylog Enterprise positively impacts the organization by helping the team and analysts investigate incidents faster since logs from servers, endpoints, cloud, and firewalls are available in one place."
"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."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"Log centralization and applying filters make my day-to-day investigations easier because when I need to investigate suspicious behavior, they help me gain agility during triage."
"A great feature of the solution involves its internal portal."
"The initial setup of Nagios Log Server was easy and straightforward."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"The product is scalable."
"My company is a featured partner of Nagios XI, so I'm implementing Nagios XI in different companies and supporting the product, and I'd recommend the solution because it offers a lot of benefits and has a good dashboard, it's pretty easy to get up and running, and the pricing is good."
 

Cons

"Graylog Enterprise is a fantastic tool, but for small and medium-sized businesses the cost ends up being high, especially in the Brazilian and Latin American market."
"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."
"The problem was with the complexity and the cost to add extensions."
"Dashboards, stream alerts and parsing could be improved."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"I believe that Graylog Enterprise could be improved. One of the negative points is that it could be more intuitive, especially for someone who is just starting to use it; depending on the amount of logs and the complexity of the query, the analysis may require a bit more technical knowledge."
"There are many other applications in the market that influenced my rating reduction."
"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 support could be better. They only offer email support."
"The configurations during initial setup could be improved."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
 

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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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 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.​​"
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"It's an open-source solution that can be used free of charge."
"We found the pricing to be quite affordable."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
