Systems monitoring enhanced by firewall and intrusion detection features

My primary use case for Fortinet FortiSIEM is systems monitoring and alerting. I use it for standard functions like log monitoring, incident detection, and notification. My customers are mostly medium-sized enterprises ranging from engineering companies, mining companies, independent schools, and…

NetFlow monitoring has improved operations but needs better configurations

For the implementation part, I am facing issues when configuring the business view. When I create the business view, I experience problems with the port interface. When I add the interface, I am confused about which interface is connected to which endpoint. If identifying the interface was easier, it would take less time to configure. Another issue is with threshold values; sometimes, it shows kilobytes (kB) while our threshold is set to gigabytes. This can be confusing. Improving this aspect would be beneficial. In URL monitoring, there is room for enhancement.

Quotes from Members

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

Pros

"Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had."

"FortiSIEM is a great tool for making security processes transparent."

"FortiSIEM's log correlation is good."

"The product is quite well-organized. The GUI makes it easy to navigate."

"Analytics. It can provide log information from the device. With log information, I can see if there is a threat"

"Fortinet FortiSIEM needs to provide better API integrations to users."

"It's very easy for anyone to work with."

"Fortinet FortiSIEM has its own validated and authentic IP database that marks malicious IP attacks against the firewall and generates an alert for the same."

More Fortinet FortiSIEM pros

"The integration with the firewall monitoring, the security monitoring, is great."

"Defining thresholds and other alerting criteria is fairly simple and would not require a lot of training. This is very useful if you are managing a large environment."

"Some of the useful features are NetFlow and analytics."

"We have found the solution to be stable."

"We use the solution to monitor links. It also helps us to track servers and monitor logs."

"The detections are fine when they work."

"The setup was easy."

"The features we found most valuable in ManageEngine OpManager are the probe server and reporting because they're pretty good features."

More ManageEngine OpManager pros

Cons

"The process of installing Fortinet FortiSIEM and the customization of the alerts take too long."

"The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."

"The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."

"I would like to see more integration with other platforms."

"When compared with some competitors, in terms of performance, the CPU and RAM requirements and the capability of coordination with development all need some improvement."

"The challenge I face with Fortinet FortiSIEM is the lack of support."

"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."

"It would be good if the solution offered even more configuration options, especially in relation to the VPN so that it continues to be a very flexible option."

More Fortinet FortiSIEM cons

"We had some stability issues at the outset that have since been resolved."

"ManageEngine OpManager can improve by having better updates for critical issues."

"With regard to configurations, however, it would be nice to have more documentation on SNMP configurations. For example, if I want to add a new vendor, it would be great if ManageEngine provided the requirements for that vendor, such as the commands needed."

"It would be great if there were some sort of artificial intelligence feature which would help us make improvements in the network once we find an issue, and do it automatically."

"The solution's reports need to include the number of applications consumed."

"We get a lot of false alerts."

"You cannot resolve 100 percent of the issues yourself. You would need to reach out to the support. It needs to be cheaper."

"The pricing could be cheaper. The initial integration does cost a bit."

More ManageEngine OpManager cons

Pricing and Cost Advice

"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."

"Manageable, however would be better as pay as you go versus CapEX."

"If one is cheap and ten is expensive. I rate the tool's price as an eight out of ten. Compared with Splunk or Oracle, Fortinet is cheap."

"The tool is really expensive. For what the tool does for our team, the price is fair."

"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."

"There is a need to make yearly payments towards the licensing charges attached to the product. The free version license of the product is available for two months."

"We pay for a license for FortiSIEM. We pay for the license and renewal."

"This is probably more on the lower cost end of the spectrum compared to competing products. Fortinet's license model is based on events per second, which makes sense, but that's not typical. It makes it very hard to calculate what your costs are going to be as you scale the platform because some log sources, such as firewall logs, are very noisy, and there are lots and lots of events per second, but some of them are not. So, it becomes a bit of a science experiment trying to guess what your costs are going to be as you scale the solution. This is where other competing products perhaps have a more straightforward license model."

More Fortinet FortiSIEM pricing and cost advice

"Pricing for ManageEngine OpManager depends on the number of nodes you onboard and whatever pricing is reflected on the ManageEngine portal which offers discounts from ten percent to fifteen percent. It purely depends on the sales volume and the negotiation. In my organization, there are about one thousand two hundred nodes which cost around $29,000 per year. There's no additional support fee or maintenance fee from ManageEngine OpManager. Pricing for the solution is highly competitive and I would rate it five out of five. ManageEngine OpManager is one of the most competitive options out there."

"ManageEngine OpManager has a three-tier licensing model."

"The solution's licensing costs are yearly and based on the number of applications."

"As far as cost, it was around six hundred thousand rands ($40,500) for the year, for the renewals. That's the total cost for a four thousand node system including support and maintenance."

"The tool's licensing costs are yearly."

"We have a standard license for ManageEngine OpManager. We purchased the license for one year and now we are upgrading it soon."

"The product is not worth the money."

"The licensing costs depend on the number of devices and accounts that are being monitored by the solution."
