Featured Reviews

Manikandan Kannan - PeerSpot reviewer
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.
Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Quotes from Members

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

Pros

"Provides detailed log reports"
"Report generation is very easy"
"One of the most valuable features is the ability to analyze data in real-time using AR features to pull data from the industrial DB. You can know what is going on and see in milliseconds where the network is underperforming."
"The reporting and organizing part of Fortinet FortiAnalyzer is very interactive, smooth, and easy to use."
"Log View is the most valuable part for us, as we can view logs from different Fortigates on a single GUI."
"It supports SQL for logging and reporting. Log data is inserted into the SQL database for log view and report generation."
"I completely recommend Fortinet FortiAnalyzer to others."
"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."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"Open source and user friendly."
"The ability to write custom alerts is key to information security and compliance."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"The product is scalable. The solution is stable."
"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."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
 

Cons

"I'm looking for something more efficient to analyze different foreign things. That's why FortiSIEM could compete with FortiAnalyzer."
"Fortinet FortiAnalyzer needs to improve in its utilization of AI to enhance its security log analysis."
"Fortinet FortiAnalyzer needs to improve its pricing flexibility."
"The product should be integrated with other third-party solutions for context exchange."
"The cost of FortiAnalyzer could be cheaper, especially when you are installing to a VM. For 90 percent of customers, the VM solution is enough."
"The UI needs to be improved in future updates."
"The upgradation process is slow"
"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 great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see some kind of visualization included in Graylog."
"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."
"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."
"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."
"With technical support, you are on your own without an enterprise license."
 

Pricing and Cost Advice

"We have around 12 devices and yearly we spend approximately $14,000."
"Fortinet FortiAnalyzer is very expensive."
"We pay approximately $11,000 for a three-year license to use Fortinet FortiAnalyzer. When we compared the price of this solution to others it is not expensive. Palo Alto is a more expensive solution."
"The pricing is reasonable."
"The number of licenses required directly corresponds with the number of devices connected."
"The enterprise version of this solution is costly. We have considered FortiAuthenticator for network control, but the pricing was focused on the larger companies and didn't suit our needs as a smaller business."
"All Fortinet programs come at a good price."
"Compared to other products, the price is a little bit high."
"I use the free version of Graylog."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We are using the free version of the product. However, the paid version is expensive."
"Having paid official support is wise for projects."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
