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 report templates are valuable. It works very well, and integrations also work well."
"The ability to gather all gateway information and logs in a single location is the most valuable feature."
"It's easy to set up the product."
"The solution allows for a lot of customization."
"The most valuable feature of the solution is reporting."
"The solution is easy to use and easy to integrate."
"The initial setup is straightforward."
"The most valuable features of Fortinet FortiAnalyzer are the GUI and there is automation that can be done with playbooks and mini-books."
"I like the correlation and the alerting."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"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."
"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."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"The solution's most valuable feature is its new interface."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
 

Cons

"I would like to see an improvement in the technical support. Stronger authentication will also be a plus."
"The solution lacks business intelligence features. It's much too basic."
"The integration between specific tenants and FortiAnalyzer can be simplified when utilizing a multi-tenant EMS for our FortiClient."
"Their pricing model is not the best and needs work."
"The solution could improve by allowing the ability to search logs in integrated solutions."
"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 is not very reliable."
"The reports are good, but they are over-summarized."
"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.​"
"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-"
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"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."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"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."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
 

Pricing and Cost Advice

"Its price is okay for us. Fortinet products are cheaper than other solutions."
"The pricing is reasonable."
"t varies depending on your needs. However, after-sales support is expensive."
"Its worth spending on FortiAnalyzer if you have multiple firewalls in your network."
"The hardware has a one-time cost and maintenance is paid by annual subscription."
"I would rate the price of FortiAnalyzer as seven out of ten, with ten being the most expensive."
"The cost of the license is high."
"The hardware cost and services contract are fair."
"We're using the Community edition."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"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."
"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."
"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."
