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

"The event handling solution in the platform is very good and useful."
"FortiAnalyzer has a robust ability to find a compromised host on your network, and when you identify a compromised host, you can address it."
"The product works well with other products."
"The solution is quite easy to deploy."
"The system provides valuable insights through information, graphics, and reports."
"With Fortinet FortiAnalyzer, it is easy to get reports and read specific logs."
"The installation process for Fortinet FortiAnalyzer was very smooth, taking around two to three hours to deploy."
"The ability to gather all gateway information and logs in a single location is the most valuable feature."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"I like the correlation and the alerting."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The product is scalable. The solution is stable."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"I am very proud of how very stable the solution is."
 

Cons

"When somebody is new to the system they find it difficult to perform certain operations, like backups, and to see where the reports are."
"The FortiAnalyzer is not good at managing multi-version environments. If all your FortiGate are at different versions in the field, that's difficult. The one thing we didn't like is the fact you have to have 100% of your environment at the same release, which is not pleasant, to have it fully functional. You can have a different release, but to have it fully functional 100% of your environment has to be the same release."
"They could always improve the interface and the user experience."
"I think some improvement is required in real-time log monitoring, as sometimes it gets stuck or displays results after a delay."
"The solution costs too much."
"If Fortinet could introduce some firewalling or maybe FortiAnalyzer on the cloud, that would be interesting because I've never seen it on a cloud."
"The setup of the solution can be improved because it is currently complex."
"Sometimes, there is a problem with CPU consumption, where one process consumes 100%, and I need to restart FortiAnalyzer to fix this."
"With technical support, you are on your own without an enterprise license."
"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."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"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 biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"I would like to see some kind of visualization included in Graylog."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
 

Pricing and Cost Advice

"Fortinet FortiAnalyzer is quite an expensive tool."
"I believe that Fortinet is a cost-effective brand, making it a competitive option in terms of pricing."
"The pricing of this solution is fair, and it is based on what you can manage."
"We have several products including Fortinet Wireless, FortiGate Firewalls, and FortiAnalyzer, which are bundled together and cost approximately $50,000 USD annually."
"The company's choice to utilize Fortinet FortiAnalyzer was based on the overall security strategy and compatibility with existing solutions. It was deemed the best fit as it provided a centralized point of visibility for all of their security solution, including Fortinet FortiGate firewall, FortiClient, Forti EMS, and FortiAP. The company conducted a thorough evaluation of various solutions in the market but found that none of them could fully integrate and manage all their solutions as effectively as Fortinet FortiAnalyzer."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"The program is expensive."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"Having paid official support is wise for projects."
"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."
"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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
