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

"The most valuable feature of Fortinet FortiAnalyzer is its performance."
"The predictive analytics of Fortinet FortiAnalyzer is very valuable for clients because this solution has a complete architecture for cybersecurity."
"The scalability of Fortinet FortiAnalyzer is excellent at a rating of ten out of ten."
"The most valuable is its robust and comprehensive reporting functionality, providing a thorough overview of various metrics."
"Fortinet FortiAnalyzer is easy; for customers with basic knowledge and for those who do not have a technical background, Fortinet is quite good and it should be the first choice."
"I would say that Fortinet's tech support is really good."
"FortiAnalyzer has a robust ability to find a compromised host on your network, and when you identify a compromised host, you can address it."
"It is a reliable product."
"Open source and user friendly."
"The ability to write custom alerts is key to information security and compliance."
"We run a containerized microservices environment, and 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."
"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
 

Cons

"The support could be better for Fortinet FortiAnalyzer here in Mexico."
"We'd like to see more embedded features."
"Fortinet FortiAnalyzer could improve by offering more detailed packet inspection information, especially where packets get dropped."
"The technical support takes at least two days to reply on any ticket post raised on their website."
"I feel that Fortinet FortiAnalyzer is a little bit heavy, making it an area where improvements are required."
"FortiAnalyzer's price could be lower."
"They can include integration with devices, such as firewalls, endpoints, from other vendors. They can include graphic monitoring of everything in the network, not just Fortinet products. It would also be good to include customizable reports and customizable views of the reports."
"It is a pretty big software package. It has a lot of features which maybe aren't that useful."
"There should be some user groups and an auto sign-in feature."
"The problem was with the complexity and the cost to add extensions."
"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."
"I would like to see some kind of visualization included in Graylog."
"There should be some user groups and an auto sign-in feature.​"
"The initial setup was really complex because I did it myself."
"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."
 

Pricing and Cost Advice

"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"The cost of the license is high."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"The number of licenses required directly corresponds with the number of devices connected."
"In the local market sometimes people are being charged more than other solutions. Although the market is competitive, legitimate suppliers do not receive a large enough discount to pass onto the customers."
"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."
"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."
"We found the price of Fortinet FortiAnalyzer to be reasonable."
"I use the free version of Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
