Featured Reviews

Oliver Jackson - PeerSpot reviewer
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…

User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"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."
"The solution’s IP database is awesome."
"FortiSIEM provides a single PIN to monitor SOC and NOC. It's a nice tool for integration and monitoring. It provides multiple categories for monitoring based on security designations like low, medium, and high."
"I like the various options, including the option for CMDB and the easier access to create rules, playbooks, or use cases. It's also easier to use for creating dashboards and reports."
"Easy alert setup which enables different alerts in different categories."
"Fortinet FortiSIEM provides good detection against advanced threats."
"It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security."
"The most valuable feature is the anomaly-reporting alarms."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"The ability to drill down and pivot from an event is one of the biggest advantage the product has compared to other things that I have seen in the market."
"The daily alerts allow me to quickly find security and operations issues which need to be addressed."
"The Web Console is my favorite. It enables me, at a glance, to see the health of the environments."
"As a SIEM, probably the best feature is that it can be tuned effectively. There are very few SIEMs out there that can be effectively tuned to provide you with meaningful information and not be overwhelmed."
"LogRhythm's GUI is easy to explore. We also like other features, such as its integration with other security solutions, log correlation, and the deployment of use cases."
"We have to be able to show the evidence, and LogRhythm does a great job of putting it forward and making it easy to create reports with nice looking dashboards, which show off what we are doing as a security program."
"NextGen SIEM's best feature is how it presents logs."
 

Cons

"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"
"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 backup and recovery process for this solution needs improvement."
"They could work on their documentation. If there's anything about the solution that needs improvement, it's that. For example, documentation already is on a very high level but specifically on the CLI there are tons of features which can be fine-tuned and thousands of commands are very difficult to document. If they could make this easier, it would improve the overall solution."
"They should enhance the solution's AI capabilities, including XDR and EDR."
"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."
"The dashboards need to be improved. It gives you so much detail, but sometimes too much detail, especially to an executive, it's too much."
"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."
"I would like to see APIs well-documented and public facing, so we can get to them all."
"My biggest complaint is documentation. Everyone tells me, "We have documentation on the Community site." I have searched for different types of documentation on numerous occasions, and it might be there, but it's not easily findable."
"I think they probably need to, because a lot of companies are having this cloud-first strategy, where anything that's new has to go into the cloud for some reason."
"One of the challenges of the SIEM for the LogRhythm 7 platform is the amount of time it takes to bring new log sources into the MDI."
"Stability has probably been one area where Health Checks have not been great with the product. We have been told that they are going to improve Health Checks on product, though we do struggle with them on a daily basis."
"I have probably submitted half a dozen log parser requests, and I keep finding more stuff that we need to keep an eye on that doesn't have a definition in LogRhythm."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
 

Pricing and Cost Advice

"The price is competitive."
"The solution is available for both, perpetual and subscription licenses."
"They have a yearly subscription."
"Please be cheaper and more simplified."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"The product is inexpensive than other tools."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"I would rate the tool's pricing around eight out of ten."
"We work with French-speaking African countries, and it costs more than the average SIEM solution. Also, the pricing isn't too flexible. AlienVault, Splunk, and IBM QRadar are more suitable for customers on a tight budget."
"I give the price a six out of ten."
"On a scale of one to ten, I'd rate the pricing of this solution as a seven - not too expensive but not cheap either. Regarding licensing costs, it varies depending on factors like being a partner or an end user, but there are no additional costs aside from standard licensing fees for the basic SIEM solution."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
