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

"I would say that Fortinet's tech support is really good."
"Overall we are satisfied with all the features the solution provides."
"Support is helpful."
"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."
"Technical reports clearly identify system checks, locations and areas, how many times things escape, which firewall is affected, and source IDs."
"The solution provides good standardized reports and is easy to troubleshoot."
"I completely recommend Fortinet FortiAnalyzer to others."
"It gives us reporting features, which are helpful in the case of troubleshooting and audit purposes."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"We run a containerized microservices environment. 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."
 

Cons

"The solution is expensive."
"The solution can improve the incident response function to provide more detailed information on where the incident is originating."
"Fortinet FortiAnalyzer could improve by offering more detailed packet inspection information, especially where packets get dropped."
"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 product should be integrated with other third-party solutions for context exchange."
"Pricing-wise, it not affordable for the normal customer. Most of the people want to see different types of reporting, but FortiAnalyzer's fee is a little bit difficult."
"Fortinet FortiAnalyzer needs to improve its pricing flexibility."
"The solution should include the ability to customize reports so that customers receive greater value and high level reporting."
"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."
"With technical support, you are on your own without an enterprise license."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"There should be some user groups and an auto sign-in feature.​"
"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."
"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."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
 

Pricing and Cost Advice

"The price of Fortinet FortiAnalyzer is expensive."
"We have several products including Fortinet Wireless, FortiGate Firewalls, and FortiAnalyzer, which are bundled together and cost approximately $50,000 USD annually."
"When you compare with other firewall vendors, FortiAnalyzer is quite competitive in pricing."
"We found the price of Fortinet FortiAnalyzer to be reasonable."
"There is a license needed to use this solution."
"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"We have around 12 devices and yearly we spend approximately $14,000."
"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."
"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."
"Having paid official support is wise for projects."
"I use the free version of Graylog."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"I am using a community edition. I have not looked at the enterprise offering from 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."
"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."
