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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The dashboard of Fortinet FortiAnalyzer is outstanding with very detailed information."
"Fortinet FortiAnalyzer is easy; for customers with basic knowledge and for those who do not have a technical background, Fortinet is quite good and it should be the first choice."
"We use the solution for enterprise firewalls, URL filtering, and SD-WAN."
"The log events are quite useful for us."
"The product can scale."
"We like the fact that we can run minute-by-minute reporting form this solution."

"Security Onion is the most mature solution in the market."
"We use Security Onion for internal vulnerability assessment."

Cons

"They should learn from CheckPoint how to design UX for admins."
"Fortinet FortiAnalyzer could be improved by enabling features such as predictive analysis. We should implement AI features, correlation of different logs, and have predictive analysis, including alerts for policy violations."
"The interface or GUI does not work properly on Microsoft Edge. The behavior or the view is different on Microsoft Edge versus on Chrome or Firefox. When some buttons do not work, I am forced to switch to Firefox."
"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."
"The UI needs to be improved in future updates."
"The user interface could be a bit more user-friendly, and they could have more robust support."
"The technical support takes at least two days to reply on any ticket post raised on their website."
"We would like to do the reporting, logging, and administration of all the public devices and all the IoT devices. We wish to add the switches, and routers from different vendors, so it's not a vendor-specific diagnostic solution."
"Security Onion's user interface could be improved."
"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."
"The initial setup of the solution is a little bit difficult."
"The product is not easy to learn."
"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

"The pricing is reasonable."
"I believe that these devices were procured with a five-year maintenance and support license up front. I work at a university, so the vendor provides a considerable higher ed discount."
"When comparing with other solutions such as Checkpoint and Cisco, Fortinet is priced well."
"I do not know the price of Fortinet FortiAnalyzer. I did not pay for it, but I know the price of other Fortinet products. They are not cheap. I am from Poland. We have Zloty, not Euro, so for us, everything is expensive."
"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 pricing model is subscription-based."
"We have several products including Fortinet Wireless, FortiGate Firewalls, and FortiAnalyzer, which are bundled together and cost approximately $50,000 USD annually."
"All Fortinet programs come at a good price."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
"It is an open-source solution."
