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

Pros

"Provides detailed log reports"
"Logging is the best feature."
"Based on the logs of Fortinet FortiAnalyzer you can have it trigger actions. For example, if the log has a word or a sentence you specified it can send an alert or Syslog to an email address."
"The product can scale."
"The solution is very easy to deploy."
"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 analyzer is the most valuable feature."
"With Fortinet FortiAnalyzer, it is easy to get reports and read specific logs."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"The product is scalable. The solution is stable."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"The solution's most valuable feature is its new interface."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"I like the correlation and the alerting."
 

Cons

"Fortinet FortiAnalyzer can improve by introducing integration with other Fortinet solutions with automation with one interface would be helpful."
"Technical support could respond to queries faster."
"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."
"It would be good if the product could provide data about the websites users visit."
"Their in-house technical support is extremely slow to respond. We have our own in-house team to manage issues so clients don't have to wait over two weeks for a response to issues."
"Fortinet FortiAnalyzer could improve by offering more detailed packet inspection information, especially where packets get dropped."
"The only issue is the cost of the licenses."
"The technical support is not very reliable."
"I would like to see some kind of visualization included in Graylog."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"The problem was with the complexity and the cost to add extensions."
"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."
"There are many other applications in the market that influenced my rating reduction."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"Dashboards, stream alerts and parsing could be improved."
 

Pricing and Cost Advice

"The price of Fortinet FortiAnalyzer is expensive."
"The pricing model is subscription-based."
"It is acceptable for on-premises, but it is expensive for the cloud."
"It is expensive for small business customers. It is only available for customers with a high number of firewalls to manage or to report. If a customer has only five boxes of FortiGate, the price of FortiAnalyzer can be more than the five boxes. So, we can't easily put this solution for small business customers."
"I rate Fortinet FortiAnalyzer's pricing as five out of ten."
"Fortinet FortiAnalyzer is quite an expensive tool."
"The cost of the license is high."
"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"We are using the free version of the product. However, the paid version is expensive."
"It's an open-source solution that can be used free of charge."
"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."
"I use the free version of Graylog."
"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."
"Having paid official support is wise for projects."
