Systems monitoring enhanced by firewall and intrusion detection features

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.

More ManageEngine OpManager pros

Cons

"The performance can be improved. Sometimes it takes a long time to fetch data."

"If there is a configuration on the wrong side of the network or there are changes that result in harm to our IT infrastructure, the solution should immediately fix it."

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

"The solution's technical support didn't help our company a lot."

"They need to integrate better with Cisco and Palo Alto."

"The dashboard needs to improve."

"Not very good on non-API features, lacks that functionality."

"Our team tried configuring MS SQL database logs with Fortinet FortiSIEM, but it did not work for some time."

More Fortinet FortiSIEM cons

"They should add more features to URL monitoring."

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

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

"We get a lot of false alerts."

"ManageEngine OpManager could improve the default dashboards that are available. We are not able to customize them easily and they do not give us the information we need unless we customize them. You need to have the technical knowledge to be able to do it, the customization should be easier."

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

"Needs an OVA, or more support for virtual deployments. Building a virtual instance of OpManager and OpManager Probe was a bit difficult because there was no OVA available."

"The dashboard could include more features."

More ManageEngine OpManager cons

Pricing and Cost Advice

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

"Please be cheaper and more simplified."

"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."

"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."

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

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

"Fortinet FortiSIEM is cheaper compared to other products."

More Fortinet FortiSIEM pricing and cost advice

"The solution is highly affordable"

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

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

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

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

"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."

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

"The initial cost is low and the add-ons are reasonable."
