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…

Real-time incident detection and user-friendly dashboard benefit daily operations
There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement. So far, it seems very limited. It shows some good features in the correlation part, but I think there is room for improvement. For instance, when creating rules, it can suggest more rules, reducing the effort needed. If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules. Sometimes logs I receive don't mean anything, and I need technical stakeholders to share or forward logs, but these are sometimes inadequate. Keywords can help identify insufficient logs. I often lack time to verify logs. Sharing false positive results could be reduced to help my team.
Mokhammad Rakhman - PeerSpot reviewer
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

"We like the integration of all of these Fortinet platforms together. Everything is integrated well, and we are able to sell that as a service to our customers."
"AccelOps can handle a lot of data and it's just so important to true monitoring. Also, I can create a lot of rules to detect anything I like."
"The most valuable features of Fortinet FortiSIEM are the SD-WAN, Global LAN, and application controls."
"It's very easy for anyone to work with."
"FortiSIEM helped us discover all the threats at the time that were attacking the IT services of the company. We now have multiple-level authentication."
"The event correlation is pretty robust. The GUI is pretty good."
"The most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"We're able to get real-timec as well as our customer networks that we're monitoring at all times."
"The scalability is awesome, because QRadar includes other solutions in the same console."
"This solution has excellent security analytics."
"We have the abilities to monitor each instance which originates on the process along with the performance of each department."
"It showed us where weaknesses were in our environment, so we could actively target those patches first."
"think QRadar is great overall. We’ve had a positive experience with it and recommend it for deployment. However, there are areas for improvement. The technical support is good, and the documentation is valuable, but it could be enhanced, especially regarding integration with other systems. In terms of support and updates, QRadar’s capabilities are crucial for maintaining high security standards. Network and software administrators can monitor all traffic effectively, which reassures clients and drives further adoption."
"QRadar, Splunk, and ArcSight are SIEM solutions with built-in AI/ML features. They can do the complete investigation and alert the admin about what is happening. They can also do the root cause analysis. There are many other features that come with QRadar. It has a more granular log, so you can integrate with various non-IT as well as IT-based components. You can get unstructured data to the SIEM data, and you can identify more what is happening in the network or what is happening in the central head office. You can also identify what is happening between your remote offices. You can also use it to identify what the users in the field are doing on their devices and how things are moving. From the integration point of view, it is very centric. It gives complete control centrally. If a user is not connected to the system, whenever he comes online, we can see the policy updates over the Internet, and we can ensure that the data that is supposed to be protected is protected."
"The solution can scale."
"It allows us to search data both on-premises and on the cloud."
"It's reliable and the performance is good."
"Overall, my rating for LogRhythm SIEM is nine out of ten."
"The most valuable features would be the automation, reporting, and the support."
"The most useful feature that I've found so far is the search function. I like all the different ways you're able to search through metadata and the different ways you're able to correlate or search through logs to find out what's going on."
"It seems like it will scale easily with the way our environment is set up."
"The major feature of this solution is its easy configuration which helps different team members to work on it effectively. This kind of feature is not available in other solutions because of a request for specialised schemes for configuration report extraction and searching. Another feature that I really admire is the significant improvement in the compliance in the auditing process by the solution. Our organisation-specific complaints require where the mailbox data needs to be forwarded, stored and searchable for a certain time period. This solution categorises data based on different types, which include cold, warm and hot data. These features allow faster and easier extraction of any data even if the event was occurring several years ago. I also like other features, especially user behaviour analysis and automation. If suddenly someone accesses your side or an unusual traffic is recorded from a user the solution flags it very effectively."
"The dashboards in the LogRhythm SIEM really help us as a starting point. It gives us a starting point we can go to every day. We walk through several dashboards to see anomalous activity for further investigation."
"I would rate the product a ten out of ten. The solution is very user-friendly and straightforward. The tool's report customization is interesting."
 

Cons

"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 built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"Patching is not great - we're not getting the support we'd expect."
"Does not have load-sharing or high-availability, and these are important things to implement. I can do the same things in another way, but not naturally having these features makes it complicated."
"The support of the product changed recently, and I don't think it's for the better. They should work to improve the support they offer to clients."
"Its training can be improved. Its price also needs to be improved."
"There is no proper guide for integration or configuration."
"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."
"The architecture could be improved. I got stuck for a long time trying to understand the architecture, as it is quite challenging."
"Search capability and indexing still lag behind competitors. We also need to see improved rule based access controls and rule/event tuning."
"The threat detection needs improvement, they have many false positives."
"The dashboard is pathetic and it takes a long time to perform a search."
"It is not app based."
"Pricing model could be more cost-effective."
"I'm not sure about the stability just yet. We've observed a few issues and we raised a supporting ticket for it."
"I don't look at only the features and benefits; I also look at the price. It is a bit expensive when compared with other solutions. It is expensive for specific deployment topologies, and the decision-makers go for alternatives like ArcSight. It should also have more AI features or capabilities for better threat intelligence. The more it uses machine learning, the better would be the dashboard, analytics, and other things."
"I don't think the cloud model in LogRhythm is developed enough."
"I would like a more fuller implementation of STIX/TAXII so I can pull in some of the government lists without having to go implement a whole new STIX/TAXII platform."
"LogRhythm's SOAR and NDR features don't stack up well against competitors. maybe integrating theme functionality as the other do. But in general, it's okay."
"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."
"The product's stability needs improvement."
"We have run into problems with stability going through upgrade processes. Recently, we have been on the front edge of the upgrade path. When that happens we tend to run into issues either with certain functionality not working after the upgrades or stability issues because of the upgrades."
"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."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
 

Pricing and Cost Advice

"Manageable, however would be better as pay as you go versus CapEX."
"Fortinet's products are not expensive, it is less than the competition."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"They have a yearly subscription."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"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."
"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"The price of this product is high."
"An X-Force feed is free with QRadar."
"The pricing is always fine."
"The licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"It's not expensive for the resources that it gives you."
"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"Go through a vulnerability assessment review for price breaks. A virtualized solution will also cut down on cost."
"Licensing can be costly depending on your architecture."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"I give the price a six out of ten."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
