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…

Every rule enriched at triggering stage, easing the job of SOC analyst
It's a Big Data security analytics platform. Among the unique features is the fact that it has built-in UEBA and analytical capabilities. It allows you to use the out-of-the-box machine learning and AI capabilities, but it also allows you to bring your own AI/ML, by bringing in your own IPs and allowing the platform to accept them and run that on top of it. In addition, the SOAR component is a pay-per-use model. Compared to any other product, where customization is not available, you can fine-tune the SOAR and you'll be charged only when your playbooks are triggered. That is the beauty of the solution because the SOAR is the costliest component in the market today. Other vendors charge heavily for the SOAR, but with Sentinel it is upside-down: the SOAR is the lowest-hanging fruit. It's the least costly and it delivers more value to the customer. The SOAR engine also uniquely helps us to automate most of the incidents with automated enrichment and that cuts out the L1 analyst work. And combining M365 with Sentinel, if you want to call it integration, takes just a few clicks: "next, next finish." If it is all M365-native, it is a maximum of three or four steps and you'll be able to ingest all the logs into Sentinel. That is true even with AWS or GCP because most of the connectors are already available out-of-the-box. You just click, put in your subscription details, include your IAM, and you are finished. Within five to six steps, you can integrate AWS workloads and the logs can be ingested into Sentinel. When it comes to a third party specifically, such as log sources in a data center or on-premises, we need a log collector so that the logs can be forwarded to the Sentinel platform. And when it comes to servers or something where there is an agent for Windows or Linux, the agent can collect the logs and ship them to the Sentinel platform. I don't see any difficulties in integrating any of the log sources, even to the extent of collecting IoT log sources. Microsoft Defender for Cloud has multiple components such as Defender for Servers, Defender for PaaS, and Defender for databases. For customers in Azure, there are a lot of use cases specific to protecting workloads and PaaS and SaaS in Azure and beyond Azure, if a customer also has on-premises locations. There is EDR for Windows and Linux servers, and it even protects different kinds of containers. With Defender for Cloud, all these sources can be seamlessly integrated and you can then track the security incidents in Microsoft's XDR platform. That means you have one more workspace, under Azure, not Defender for Cloud, where you can see the security incidents. In addition, it can be integrated with Sentinel for EDR deep-dive analytics. It can also protect workloads in AWS. We have customers for whom we are protecting their AWS workloads. Even EKS, Elastic Kubernetes Service, on AWS can be integrated, as can the GKE (Google Kubernetes Engine). And with Defender for Cloud, security alert ingestion is free

Quotes from Members

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

Pros

"To add workers and even collectors is pretty easy."
"The most fascinating aspect of FortiSIEM is its integration with the MITRE ATT&CK framework."
"Both the collecting logs and duo correlation are valuable features for us."
"We find the solution to be stable."
"FortiSIEM allows you to match IPs with threat intelligence feeds from sources like Kaspersky or Anomali, adding valuable context."
"Fortinet FortiSIEM provides good detection against advanced threats."
"The most valuable features of the solution is its integration with other technologies, especially its ability to collect logs from Cisco and Aruba devices along with Fortinet products."
"It works well with medium to large-scale enterprises."
"The most valuable features are its threat handling and detection. It's a powerful tool because it's based on machine learning and on the behavior of malware."
"Free ingestion for Azure logs (with E5 licence)"
"The automation feature is valuable."
"The most valuable features in my experience are the UEBA, LDAP, the threat scheduler, and integration with third-party straight perform like the MISP."
"The scalability is great. You can put unlimited logs in, as long as you can pay for it. There are commitment tiers, up to six terabytes per day, which is nowhere close to what any one of our customers is running."
"We have no complaints about the features or functionality."
"Sentinel is a Microsoft product, so they provide very robust use cases and analytic groups, which are very beneficial for the security team. I also like the ability to integrate data sources into the software for on-premise and cloud-based solutions."
"The Log analytics are useful."
 

Cons

"The process of installing Fortinet FortiSIEM and the customization of the alerts take too long."
"The backup and recovery process for this solution needs improvement."
"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 solution's interface could be modernized and improved."
"Fortinet FortiSIEM is a little out of sight and needs more marketing efforts to be popular in the market."
"Their technical support is horrible. By horrible, I mean a train wreck of a disaster that has fallen off a bridge and caught fire."
"The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."
"The solution's technical support didn't help our company a lot."
"Microsoft Sentinel's search efficiency can be improved, especially for queries spanning large datasets or long timeframes like 90 days compared to competitors like Splunk."
"Sentinel could improve its ticketing and management. A few customers I have worked with liked to take the data created in Sentinel. You can make some basic efforts around that, but the customers wanted to push it to a third-party system so they could set up a proper ticketing management system, like ServiceNow, Jira, etc."
"We have been working with multiple customers, and every time we onboard a customer, we are missing an essential feature that surprisingly doesn't exist in Sentinel. We searched the forums and knowledge bases but couldn't find a solution. When you onboard new customers, you need to enable the data connectors. That part is easy, but you must create rules from scratch for every associated connector. You click "next," "next," "next," and it requires five clicks for each analytical rule. Imagine we have a customer with 150 rules."
"It would be good to have some connectors for third-party SIEM solutions. Many customers are struggling with the integration of Azure Sentinel with their on-premise SIEM. Microsoft is changing the log structure many times a year, which can corrupt a custom integration. It would be good to have some connectors developed by Microsoft or supply vendors, but they are not providing such functionality or tools."
"The solution should allow for a streamlined CI/CD procedure."
"We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed."
"The troubleshooting has room for improvement."
"Sentinel should be improved with more connectors. At the moment, it only covers a few vendors. If I remember correctly, only 100 products are supported natively in Sentinel, although you can connect them with syslog. But Microsoft should increase the number of native connectors to get logs into Sentinel."
 

Pricing and Cost Advice

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"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."
"Please be cheaper and more simplified."
"Fortinet FortiSIEM is cheaper compared to other products."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"Fortinet's products are not expensive, it is less than the competition."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"Azure Sentinel is very costly, or at least it appears to be very costly. The costs vary based on your ingestion and your retention charges."
"Sentinel is a bit expensive. If you can figure a way of configuring it to meet your needs, then you can find a way around the cost."
"Currently, given our use case, the cost of Sentinel is justified, but it is expensive."
"For us, it is not expensive at this time, but if we start to collect all logs from our on-premise SIEM solutions, it will cost more than QRadar. If we calculate its cost over the next five or ten years, it will cost more than what we paid for QRadar."
"The pricing is reasonable, and we think Sentinel is worth what we pay for it."
"Sentinel is costly."
"Good monthly operational cost model for the detection and response outcomes delivered, M365 logs don't count toward the limits which is a good benefit."
"Sentinel is a pay-as-you-go solution. To use it, you need a Log Analytics workspace. This is where the logs are stored and the cost of Log Analytics is based on gigabytes... On top of that, there is the cost of Sentinel, which is about €2 per gigabyte. If a customer has an M365 E5 license, the logs that come from Microsoft Defender are free."
