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 monitoring has strengthened threat detection and supports faster incident investigations

Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization. Security Onion integrates well with our existing tools, primarily using Linux systems in our organization, allowing us to monitor logs and manage threat detection and operations in the public cloud effectively. Security Onion is very helpful in meeting compliance requirements and supports regular standards for our environment. I advise organizations that use Linux or have network security knowledge to consider Security Onion, as it satisfies requirements such as threat detection and log management systems. I would rate this review eight out of ten.

Quotes from Members

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

Pros

"One of the most valuable features is the ability to analyze data in real-time using AR features to pull data from the industrial DB. You can know what is going on and see in milliseconds where the network is underperforming."

"Stability-wise, I rate the solution a ten out of ten since, in our company, we have never experienced the solution crashing or having any other issues."

"This solution, at every stage, does what I expect it to."

"Separating sections or conditions on Fortinet FortiAnalyzer is quite clear."

"FortiAnalyzer ensures you have an accurate view of all your devices, so you don't need to check each one."

"Logging is the best feature."

"For us in Latin America, the best features of Fortinet FortiAnalyzer are the solutions that combine SD-WAN and security in the same box."

"The solution allows for a lot of customization."

More Fortinet FortiAnalyzer pros

"Security Onion is the most mature solution in the market."

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

"We use Security Onion for internal vulnerability assessment."

"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."

Cons

"I think some improvement is required in real-time log monitoring, as sometimes it gets stuck or displays results after a delay."

"Feature-wise, it is working very well for us. We don't need any additional features. However, its pricing can be improved. For small business customers, price is an important factor."

"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 reports are good, but they are over-summarized."

"The UI could use some improvement. It can be tough for a beginner to navigate because you don't know what to do even if you read the guide. I've talked to some users who said that they couldn't figure out what to do even after looking at the documentation."

"It should have customized reports as well. While it currently has them, you need to write a script which is not straightforward."

"The solution does not function well with third-party tools"

"One of the main disadvantages is not having a direct link to the security policy when you see something in the log."

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."

"The product is not easy to learn."

"The initial setup of the solution is a little bit difficult."

"Security Onion's user interface could be improved."

Pricing and Cost Advice

"I rate FortiAnalyzer six out of 10 for affordability. FortiAnalyzer pricing isn't steady. It changes each quarter or year. That's one of the main problems in West Abaco because most businesses here are small or medium-sized enterprises. It makes budgeting complicated. You always want to pay the same price on the subscription."

"All Fortinet programs come at a good price."

"In other countries, the product may seem cheap, but in Vietnam, the costs are high."

"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."

"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."

"We pay for an annual license."

"The pricing of this solution is fair, and it is based on what you can manage."

"We have around 12 devices and yearly we spend approximately $14,000."

"Security Onion is a free solution."
