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…

Reporting features improve operational efficiency while weekend support needs enhancement

Support is moderate and needs improvement, especially during weekends when technicians perform upgrades. During weekends, they need to provide more support to ensure a smooth transition. There is a call for ManageEngine OpManager to scale better in automation and AI functionality. Although the product stability is good, support enhancement is necessary to enable better planning for upgrades and maintenance activities.

Quotes from Members

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

Pros

"The stability is very reliable. It offers very good performance."

"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."

"Fortinet FortiSIEM is highly scalable. I would rate its scalability nine out of ten."

"The most valuable feature is the dashboard. CMDB database collects data from a lot of pre-configured devices."

"It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security."

"FortiSIEM sends an email or SMS notifications to admins when there are significant incidents. It's a highly efficient way of responding to incidents."

"The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install."

"The seamless integration with FortiGate is the solution's most valuable aspect."

More Fortinet FortiSIEM pros

"We find the networking aspect of this solution to be the most valuable."

"I like being able to push configurations to multiple devices. If you have the same configurations for all the branches, it's easier to use ManageEngine OpManager and push configurations at once rather than individually pushing them to each device."

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

"You can put all of your work on there, they'll send you an email or send you a text. That functionality as a network engineer is the one I like the most. I do like the fact that we can schedule reports. That works too because that's a lot fewer spreadsheets that I have to create."

"The setup was easy."

"The application monitoring is the solution's most valuable feature."

"OpManager can monitor network utilization, downtime, and services in real time."

"The most valuable feature of ManageEngine OpManager is the management of the virtual machine and the host machine."

Cons

"The stability of the product is an area of concern where improvements are required."

"Their product support, in general, is not that great. The product support is in the same ecosystem. Their support is improving but it's not that great.vvv"

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

"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."

"It lacks a "wizard" that shows a particular user's activity or particular circumstance. I think the interface is intimidating because there's so much information there."

"Fortinet FortiSIEM could improve by having better integration and extensions. This would benefit by allowing us to give more rules."

"Fortinet FortiSIEM could improve to extend to several locations or sites."

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

More Fortinet FortiSIEM cons

"The integration with various OEM products could be simplified."

"We have been facing an issue since last year when a lot of our users started to work from home through their mobiles or computers. We are having trouble reaching these devices. We are now planning to publish our instance to the cloud so that we can reach these devices. Its performance should be improved in terms of the discovery of the devices. I would like to feel confident with the discovery that this solution does. For example, on my dashboard, I would like to be able to view a list of all devices seen on a specific server. At present, it is difficult to find such information. This would be an excellent feature to have."

"There should be an option to get mobile notifications or SMS mirror notifications for critical issues. That way, when we don't have access to email, we can still receive notifications via our phones."

"It is sometimes difficult to manage the user interface. It can get very complicated."

"For the implementation part, I am facing issues when configuring the business view."

"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."

"They should add more features to URL monitoring."

"The licensing for this solution is not straightforward and should be improved."

Pricing and Cost Advice

"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."

"Please be cheaper and more simplified."

"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."

"Fortinet's products are not expensive, it is less than the competition."

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."

"The price is competitive."

"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."

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

More Fortinet FortiSIEM pricing and cost advice

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

"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."

"It is not really expensive; it is nominal licensing."

"The price for ManageEngine OpManager is average."

"The solution's pricing is very low compared to other products."

"The price of ManageEngine OpManager is reasonable. We have an annual license and the cost comes from how many devices are being monitored. There is not anything extra cost for maintenance and support."

"The pricing is moderate."

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