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

"It is a simple and solution."
"The log events are quite useful for us."
"Log collection is the most valuable. The UI looks great. It has a very good look and feel. We don't have the need to use solid state drives. We use mechanic drives, and we don't see any performance issues, so basically, it is doing fine."
"The most valuable feature is the capability to create a customized dashboard."
"The most valuable is its robust and comprehensive reporting functionality, providing a thorough overview of various metrics."
"With Fortinet FortiAnalyzer, it is easy to get reports and read specific logs."
"For us in Latin America, the best features of Fortinet FortiAnalyzer are the solutions that combine SD-WAN and security in the same box."
"Logging is the best feature."
"The solution's most valuable feature is its new interface."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"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."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"Graylog is very handy."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Open source and user friendly."
 

Cons

"If Fortinet could introduce some firewalling or maybe FortiAnalyzer on the cloud, that would be interesting because I've never seen it on a cloud."
"Their pricing model is not the best and needs work."
"The deployment of Fortinet FortiAnalyzer is not complex, but integrating it with firewalls can take some time, depending on the number of firewalls."
"The traffic monitoring could be better, and stability could be improved."
"A possible improvement for FortiAnalyzer could be in threat intelligence."
"Software reports are good but should match the dashboard and include top-level output instead of just base or low-level devices."
"It doesn't easily integrate with other solutions."
"We should be able to do the patch upgrades in a centralized manner. This functionality is currently not there. It would be good to be able to do the firmware updates from one place and at the same time. Currently, if we want to update all appliances, we require FortiManager, which is another solution from Fortinet. Its documentation can be improved. It will be helpful for implementing the product and gaining knowledge for management purposes."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"More customization is always useful."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"There are many other applications in the market that influenced my rating reduction."
"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."
"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."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"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."
 

Pricing and Cost Advice

"When you compare with other firewall vendors, FortiAnalyzer is quite competitive in pricing."
"The pricing model is subscription-based."
"I believe that these devices were procured with a five-year maintenance and support license up front. I work at a university, so the vendor provides a considerable higher ed discount."
"I do not know the price of Fortinet FortiAnalyzer. I did not pay for it, but I know the price of other Fortinet products. They are not cheap. I am from Poland. We have Zloty, not Euro, so for us, everything is expensive."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"t varies depending on your needs. However, after-sales support is expensive."
"The number of licenses required directly corresponds with the number of devices connected."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Having paid official support is wise for projects."
"I use the free version of Graylog."
"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."
"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.​"
"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."
"We are using the free version of the product. However, the paid version is expensive."
