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 solution is easy to use and easy to integrate."
"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 most important feature is to be able to get reports or information about the state of all firewalls."
"With Fortinet FortiAnalyzer, it is easy to get reports and read specific logs."
"I recommend Fortinet FortiAnalyzer."
"The most valuable feature of the solution is reporting."
"Stability-wise, I rate the solution a ten out of ten since, in our company, we have never experienced the solution crashing or having any other issues."
"It has a simplified and user-friendly interface."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"I like the correlation and the alerting."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"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."
"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

"For smaller SMB-level firewalls, Fortinet FortiAnalyzer might not be the best idea for cost-effective implementation."
"The user interface could be a bit more user-friendly."
"The integration between specific tenants and FortiAnalyzer can be simplified when utilizing a multi-tenant EMS for our FortiClient."
"The solution could improve by allowing the ability to search logs in integrated solutions."
"Fortinet FortiAnalyzer could be improved by enabling features such as predictive analysis. We should implement AI features, correlation of different logs, and have predictive analysis, including alerts for policy violations."
"The pricing could be better. They could work to make it more competitive on the market."
"Feature-wise, it is working very well for us. We don't need any additional features. However, its pricing can be improved. For small business customers, price is an important factor."
"A possible improvement for FortiAnalyzer could be in threat intelligence."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"Dashboards, stream alerts and parsing could be improved."
"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."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"There should be some user groups and an auto sign-in feature.​"
"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."
 

Pricing and Cost Advice

"I rate FortiAnalyzer six out of 10 for affordability. FortiAnalyzer pricing isn't steady. It changes each quarter or year. That's one of the main problems in West Abaco because most businesses here are small or medium-sized enterprises. It makes budgeting complicated. You always want to pay the same price on the subscription."
"We have around 12 devices and yearly we spend approximately $14,000."
"The solution is quite expensive"
"I won't say the solution is too costly since it is available at a fair price."
"Fortinet FortiAnalyzer is quite an expensive tool."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"The hardware cost and services contract are fair."
"It's an open-source solution that can be used free of charge."
"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 use the free version of Graylog."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Having paid official support is wise for projects."
