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.

We currently do not use that feature. We currently have just an open-source release, not a premium release. My boss has indicated that he wants to buy a premium syslog-ng version next month. I think we can use other features of this tool in the future. In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it.

Quotes from Members

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

Pros

"The solution is quite easy to deploy."
"I like its simplicity."
"It's a very stable product."
"The most valuable feature of Fortinet FortiAnalyzer is the capturing of traffic for reports."
"If a company purchases FortiGate they should purchase Fortinet FortiAnalyzer together because FortiGate does not have an interface for analyzing logs but if you have the Fortinet FortiAnalyzer it can analyze logs and give reports on the logs giving you more protection."
"The ability to gather all gateway information and logs in a single location is the most valuable feature."
"It is a reliable product."
"Our use case for Fortinet FortiAnalyzer is analyzing traffic. We use it to investigate complaints about account access, check if something is blocked or working, and understand what's happening inside them."
"The ability to extract and store the logs is the most valuable feature of syslog-ng."
"Syslog-ng provides easy access to all my logs. It helps me show managers and other clients precisely where an incident occurred. I also like it because you can integrate syslog-ng with multiple solutions to allow real-time monitoring."
"We chose syslog-ng because it is easy to install, easy to maintain, easy to update, and due to the fact that all data arrive in raw format, we can manipulate it as we want."
"Syslog-ng has built-in features that we can use to create alerts for a SIEM solution. It isn't a true SIEM solution, but it's sufficient for the time being."
"What I appreciate most about syslog-ng is its configuration; its C-style config is much easier to understand, read, and write than other popular solutions such as syslog or rsyslog."
"Syslog-ng has a separate config file in addition to the core configuration."
"For us, the most valuable feature is the use of compound search for searching logs at a specific time, by a specific user, or specific behavior."
 

Cons

"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."
"The cloud version can be expensive. If the customers could get the resources to store the logs on-premises, it would be much better."
"One thing we struggled with FortiAnalyzer was integration with SIEM. We also had issues with the new threats and APTs. There were false positives, so we needed to have some ratings related to false positives."
"We'd like to see more embedded features."
"The pricing could be better. They could work to make it more competitive on the market."
"We don't need to do much to install FortiAnalyzer because it always depends on FortiGate. You need to deploy FortiGate before you install it. That's why I say that I see it as a dummy box. I don't see anything interesting in it. It's only a support structure."
"We would like to see some improvement on the upgrade process around this solution. There are sometimes communication issues when a new version of the firewall is implemented, and it fails to report back to this product."
"It's possible that they could add some advanced analytics and some proactive controls for logging analytics. That will help a lot."
"There is room for improvement in terms of observability."
"The filtering has room for improvement."
"In syslog-ng, I think a GUI would be beneficial. I am unsure if the premium module has a GUI to administer it."
"There is always the potential for additional integration and protocol extensions."
"It's hard to find people who know how to use syslog-ng. I often find problems with configurations, and solutions aren't integrated correctly with syslog-ng. For example, there might be data with extra decimals, or the collector agents are incorrectly named. It isn't a problem with the solution; it's a lack of professionals."
 

Pricing and Cost Advice

"FortiAnalyzer was in the product itself, but two years ago they split it from Fortinet. We paid the license two years ago."
"The hardware cost and services contract are fair."
"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."
"It is acceptable for on-premises, but it is expensive for the cloud."
"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."
"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."
"I would rate the price of FortiAnalyzer as seven out of ten, with ten being the most expensive."
"​It depends upon the company.​"
"Syslog-ng is open-source."
"Syslog-ng is a free open-source solution."
