Comprehensive log analysis has improved traffic monitoring and streamlined risk mitigation

Fortinet FortiAnalyzer is a very comprehensive analyzer providing detailed analyzing features and customizable reports. I can get customization and custom reports, and there are many functions available. It is very good for any organization.Log management in Fortinet FortiAnalyzer is excellent, as it stores approximately two years of logs. Using Fortinet FortiAnalyzer, I analyze vulnerability risks and threats and sort out problems accordingly. I then create policies and mitigate the risk based on my findings. I have created many customizable reports in Fortinet FortiAnalyzer. I have customized the reports to schedule them and generate reports every day that are sent to my email. I am not using any SIEMs, but Fortinet FortiAnalyzer is the best and looks like a SIEM. I did not integrate Fortinet FortiAnalyzer with any security information and event management solutions. With Fortinet FortiAnalyzer, I have streamlined the process to mitigate risks and save time to get event information on any type of threats, risks, and unwanted traffic. Risk and time are saved, and it is valuable for any organization.

Centralized threat monitoring has improved visibility but demands complex setup and configuration

The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Cons

"FortiAnalyzer only works with other Fortinet products. If you need to analyze the data from other devices, other vendors, this solution is not the best one to use."

"Fortinet FortiAnalyzer could improve the user interface, and the experience of users receiving the reports and tracking could be better."

"FortiAnalyzer is a good product; but, I keep thinking that FortiAnalyzer isn't really what I'm looking for which is why I am looking to acquire a SIEM solution."

"The pricing could be better. They could work to make it more competitive on the market."

"The integration with other vendors for log collection could be enhanced."

"I'm looking for something more efficient to analyze different foreign things. That's why FortiSIEM could compete with FortiAnalyzer."

"They can include integration with devices, such as firewalls, endpoints, from other vendors. They can include graphic monitoring of everything in the network, not just Fortinet products. It would also be good to include customizable reports and customizable views of the reports."

"I would like to see an improvement in the technical support. Stronger authentication will also be a plus."

More Fortinet FortiAnalyzer cons

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

Pricing and Cost Advice

"It is expensive for small business customers. It is only available for customers with a high number of firewalls to manage or to report. If a customer has only five boxes of FortiGate, the price of FortiAnalyzer can be more than the five boxes. So, we can't easily put this solution for small business customers."

"The product's prices are a bit higher than the other solutions available in the market, but I would say that the tool's quality and support are areas that are good."

"The number of licenses required directly corresponds with the number of devices connected."
