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

"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 of the solution is reporting."
"The IBS (Intent Based Segmentation) and application web filtering are the most valuable aspects of the solution."
"It is very stable and reliable."
"Many of my clients are financial institutions that transmit files from around the country across a VPN. In a setup like this, it's helpful to have a centralized dashboard to manage firewalls and other security solutions across a distributed environment. You can do all sorts of analysis and configure it to trigger alarms."
"The analyzer is the most valuable feature."
"With Fortinet FortiAnalyzer, I have streamlined the process to mitigate risks and save time to get event information on any type of threats, risks, and unwanted traffic."
"Logging is the best feature."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"The solution's most valuable feature is its new interface."
"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."
"The ability to write custom alerts is key to information security and compliance."
"Troubleshooting is straightforward with Graylog Enterprise."
"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."
"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."
"I am very proud of how very stable the solution is."
 

Cons

"The product should be integrated with other third-party solutions for context exchange."
"The interface or GUI does not work properly on Microsoft Edge. The behavior or the view is different on Microsoft Edge versus on Chrome or Firefox. When some buttons do not work, I am forced to switch to Firefox."
"The solution could improve by allowing the ability to search logs in integrated solutions."
"Software reports are good but should match the dashboard and include top-level output instead of just base or low-level devices."
"FortiAnalyzer's price could be lower."
"Fortinet FortiAnalyzer should come bundled with other Fortinet solutions. Additionally, the performance and updates could improve. They need to test their updates better so there are not as many bugs."
"They need to make the monitor better."
"Pricing-wise, it not affordable for the normal customer. Most of the people want to see different types of reporting, but FortiAnalyzer's fee is a little bit difficult."
"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."
"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."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"There should be some user groups and an auto sign-in feature."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"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-"
 

Pricing and Cost Advice

"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"The pricing model is subscription-based."
"I rate Fortinet FortiAnalyzer's pricing as five out of ten."
"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"The hardware cost and services contract are fair."
"The product's prices are a bit higher than the other solutions available in the market, but I would say that the tool's quality and support are areas that are good."
"The pricing of this solution is fair, and it is based on what you can manage."
"The solution is quite expensive"
"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."
"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."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"It's an open-source solution that can be used free of charge."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Having paid official support is wise for projects."
