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 like its simplicity. It is straightforward. We get reports and emails about the logs, and that's it."
"Logging is the best feature."
"Storage in SSD helps in generating customized reports."
"I would say that Fortinet's tech support is really good."
"I have found incident management and also identifying new threats, analyzing the network traffic, and finding out the issues with the network traffic such as any security issues to be valuable. I also like the compliance reports."
"Fortinet FortiAnalyzer is a complete package for managing our equipment."
"This makes it easy to configure and use. I would recommend it to anyone."
"The initial setup is easy, and the deployment is fast."
"The product is scalable. The solution is stable."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"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."
"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."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"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."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
 

Cons

"We are concerned about the compliance of our policy and institutional philosophy."
"Fortinet FortiAnalyzer needs to have more out-of-the-box connectors for integration with other solutions."
"From my point of view, at this time, the solution isn't lacking any features or functionalities."
"The solution can improve the incident response function to provide more detailed information on where the incident is originating."
"The solution should be more price competitive."
"It should have customized reports as well. While it currently has them, you need to write a script which is not straightforward."
"Fortinet FortiAnalyzer needs to improve in its utilization of AI to enhance its security log analysis."
"Currently, Fortinet FortiAnalyzer provides a very basic level of correlation facilities. I would like to see improvements in the integration of better correlation capabilities."
"With technical support, you are on your own without an enterprise license."
"There should be some user groups and an auto sign-in feature.​"
"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."
"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."
"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."
"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."
"Lacks sufficient documentation."
"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

"We have around 12 devices and yearly we spend approximately $14,000."
"The hardware has a one-time cost and maintenance is paid by annual subscription."
"The price is not expensive when compared to other solutions like Palo Alto."
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"The number of licenses required directly corresponds with the number of devices connected."
"Compared to other products, the price is a little bit high."
"We pay for an annual license."
"The pricing model is subscription-based."
"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."
"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."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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."
