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 ability to gather all gateway information and logs in a single location is the most valuable feature."
"It supports SQL for logging and reporting. Log data is inserted into the SQL database for log view and report generation."
"The most valuable feature of Fortinet FortiAnalyzer is its ability to report for several management tasks in a very short time."
"It has a simplified and user-friendly interface."
"The initial setup is straightforward."
"It is one of the best firewall products."
"The initial setup is easy, and the deployment is fast."
"We have the most data visibility."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"Open source and user friendly."
"The solution's most valuable feature is its new interface."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"The ability to write custom alerts is key to information security and compliance."
"Real-time UDP/GELF logging and full text-based searching."
 

Cons

"The integration with other vendors for log collection could be enhanced."
"The pricing could be better."
"The following could be better: operation and maintenance, high-availability architecture, and management link embedded in the transmission link."
"Though FortiAnalyzer has improved over the last few versions, the user interface still has room for improvement. It's a bit dated-looking."
"Their pricing model is not the best and needs work."
"The solution is expensive."
"It is very important that FAZ can support FortiController as the architecture designed for the network. FortiController should be registered in FAZ at least for event logs."
"When it comes to pushing logs to a SIEM, most of the time we have some issues when it comes to filtering."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"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 infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"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."
"With technical support, you are on your own without an enterprise license."
"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."
"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-"
"More customization is always useful."
 

Pricing and Cost Advice

"In the local market sometimes people are being charged more than other solutions. Although the market is competitive, legitimate suppliers do not receive a large enough discount to pass onto the customers."
"The pricing is reasonable."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"We have around 12 devices and yearly we spend approximately $14,000."
"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."
"In other countries, the product may seem cheap, but in Vietnam, the costs are high."
"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."
"Having paid official support is wise for projects."
"I use the free version of 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."
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"We're using the Community edition."
