Engineer at Kahramaa
Management becomes centralized with effective logging
The features that are most effective for me in Fortinet FortiAnalyzer are easy to manage. Fortinet FortiManager is also a great product to manage multi-site management options and other tools. The capability of logging in Fortinet FortiAnalyzer is great because there is no need to go to each individual box to check the traffic details. We can collect everything in Analyzer and check from a single console.

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

"I would say that Fortinet's tech support is really good."
"There are customizable workflows that you can work with. You can automate certain tasks in FortiAnaylzer in the incidents and events sections."
"The features that our customers have found most valuable are their different type of reports including the drill down report, as well as the flexibility to connect to any number of appliances which can be connected to it centrally."
"Overall we are satisfied with all the features the solution provides."
"The most valuable aspect of the solution is its ability to pinpoint where the issue is, and if two devices need to communicate together, you can see which interfaces they are using."
"The most valuable feature of Fortinet FortiAnalyzer is its capability for analyzing and providing visually comprehensive reports, making it easier to understand the network environment."
"We have the most data visibility with this solution."
"It gives you live logs, which can be really helpful during troubleshooting."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"Graylog is very handy."
"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."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"I would consider myself Graylog2's number one fan or at least a big advocate of the utility of this product."
"Message forwarding through the in-built module."
"The product is scalable. The solution is stable."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
 

Cons

"In terms of what could be improved, sometimes it's lagging and it also has some graphical issues with the GUI."
"One area for improvement could be better support for third-party products, as it doesn't have as much visibility with these compared to Fortinet's own products."
"The technical support isn't very good, I rate it a 2 out of 5."
"Automated reports focusing on compliance issues would provide a clearer understanding of potential gaps and the need for remediation."
"The correlation mechanism and the analytics are not as good as the competitors like Check Point or Panorama."
"I think some improvement is required in real-time log monitoring, as sometimes it gets stuck or displays results after a delay."
"The following could be better: operation and maintenance, high-availability architecture, and management link embedded in the transmission link."
"One thing we struggled with FortiAnalyzer was integration with SIEM."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"There are many other applications in the market that influenced my rating reduction."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"The alerting system could be more flexible."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"I would like to see some kind of visualization included in Graylog."
 

Pricing and Cost Advice

"The program is expensive."
"We have around 12 devices and yearly we spend approximately $14,000."
"The price is quite expensive. Fortinet products are very expensive. That is something which they should also look at, because if you compare Fortinet product to, say, Sophos for example, Fortinet is really high and that's the only thing which is a drawback for most users."
"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."
"I would rate the price of FortiAnalyzer as seven out of ten, with ten being the most expensive."
"I believe that these devices were procured with a five-year maintenance and support license up front. I work at a university, so the vendor provides a considerable higher ed discount."
"The hardware has a one-time cost and maintenance is paid by annual subscription."
"Its price is okay for us. Fortinet products are cheaper than other solutions."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"It's an open-source solution that can be used free of charge."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
"Having paid official support is wise for projects."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
