Simplifying log management by displaying detailed access information
The most valuable feature of Fortinet FortiAnalyzer is its ability to simplify and display logs clearly, providing details like which IPs are accessing the system, the destination, and the policies applied. This visualization and detail make managing logs more straightforward. In conjunction with our VMware setup, Fortinet FortiAnalyzer enhances organizational efficiency, meeting the standard log retention period for up to a year.

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.

Quotes from Members

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

Pros

"I think Fortinet FortiAnalyzer is the best security solution in the world."
"I find it easy to deploy Fortinet products, including the firewall, Fortinet FortiAnalyzer, and many other Fortinet products."
"The most valuable feature is the capability to gather logs and generate reports."
"The log events are quite useful for us."
"It gives you live logs, which can be really helpful during troubleshooting."
"The analyzer is the most valuable feature."
"FortiAnalyzer's reporting features like graphs, threat intelligence, and vulnerabilities analysis are helpful. Fortinet knows how to do reporting. You can customize your reports to show exactly what you want to analyze. It's user-friendly and doesn't require a lot of effort."
"The event handling solution in the platform is very good and useful."
"Real-time UDP/GELF logging and full text-based searching."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"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 Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm."
"The product is scalable. The solution is stable."
"The ability to write custom alerts is key to information security and compliance."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"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."
 

Cons

"Fortinet FortiAnalyzer can improve by introducing integration with other Fortinet solutions with automation with one interface would be helpful."
"Pricing should be about 10-20% lower."
"From my point of view, at this time, the solution isn't lacking any features or functionalities."
"The setup of the solution can be improved because it is currently complex."
"The product's high price is an area of concern where improvements are required."
"The UI can be more user-friendly for new users."
"The support could be better for Fortinet FortiAnalyzer here in Mexico."
"The following could be better: operation and maintenance, high-availability architecture, and management link embedded in the transmission link."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"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."
"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."
"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."
"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 area in Graylog that needs to be improved or enhanced would be the integrations."
"Lacks sufficient documentation."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
 

Pricing and Cost Advice

"The solution is quite expensive"
"I believe that Fortinet is a cost-effective brand, making it a competitive option in terms of pricing."
"​It depends upon the company.​"
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"The number of licenses required directly corresponds with the number of devices connected."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"Its price is okay for us. Fortinet products are cheaper than other solutions."
"Compared to other products, the price is a little bit high."
"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.​​"
"Having paid official support is wise for projects."
"We're using the Community edition."
"It's an open-source solution that can be used free of charge."
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
