We use the Fortinet FortiSIEM tool for log monitoring and alert generation. We use Fortinet FortiSIEM to collect logs from the critical servers of the customer's infrastructure, like active directory servers and file servers. We also collect logs from a few security devices like the firewall, the proxy, and the antivirus setup. Based on that, our team checks the logs, and we get an alert to take action on the development.

902,270 professionals have used our research since 2012.
What do I think about the stability of the solution?
Fortinet FortiSIEM is a stable product.
What do I think about the scalability of the solution?
Fortinet FortiSIEM is a scalable product. We initially configured five devices, and then we could scale it to twenty. There could be some issues if the device count goes up to hundreds and thousands. Around 10 to 15 engineers use Fortinet FortiSIEM in our company.
What other advice do I have?
Overall, I rate Fortinet FortiSIEM an eight out of ten.
Which deployment model are you using for this solution?
On-premises
Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Cyber Security Specialist at EAST-NB
It integrates well with solutions by the same vendor and other popular third-party vendors
Pros and Cons
- "I like FortiSIEM because it integrates natively with our other Fortinet solutions and the Fortinet Fabric, but it also integrates with Cisco, Palo Alto and other security fabrics."
- "The only drawback is the licensing model. It can get expensive if you want to integrate more solutions."
What is our primary use case?
I primarily use FortiSIEM for Rwandan clients in banking and finance. Most of my clients require strictly on-prem solutions because of national data regulations. They are also skeptical of putting their data on the cloud, and the law requires all data to reside at a domestic data center.
What is most valuable?
I like FortiSIEM because it integrates natively with our other Fortinet solutions and the Fortinet Fabric, but it also integrates with Cisco, Palo Alto and other security fabrics.
What needs improvement?
The only drawback is the licensing model. It can get expensive if you want to integrate more solutions.
What do I think about the stability of the solution?
I rate FortiSIEM eight out of 10 for stability.
What do I think about the scalability of the solution?
FortiSIEM is highly scalable, but you need to consider the costs. It will be expensive if you want to scale it up.
How are customer service and support?
We rely on Fortinet support, and their response times have room for improvement. They can take a while to respond sometimes.
How was the initial setup?
Setting up FortiSIEM is straightforward because they provide you with a step-by-step guide that covers installation and troubleshooting. The deployment time depends on your setup and what you need to integrate. It can take days or weeks, but we can typically finish in under a week.
There isn't a single one-size-fits-all implementation because some clients have mixed environments, and we need to develop a custom solution if we are working on multiple fabrics.
What's my experience with pricing, setup cost, and licensing?
You can get an annual license for FortiSIEM or a three-year license. It can be expensive if you're pulling data from many sources. If you plan to keep the solution for a while, I recommend choosing a three-year license or longer to save money.
What other advice do I have?
I rate FortiSIEM eight out of 10. My only advice is to understand your environment and learn as much as you can about SIEM before implementing the solution. I started by building open-source solutions from scratch, which gave me a big picture view of how to implement SIEM solutions and work with fabrics. You need to learn the basics about how to set rules and interpret logs.

Solution Consultant at 1&1 Versatel Deutschland GmbH
It's a good tool for making security processes transparent
Pros and Cons
- "FortiSIEM is a great tool for making security processes transparent."
What is our primary use case?
FortiSIEM combines information from operations and integrates it into management.
What is most valuable?
FortiSIEM is a great tool for making security processes transparent.
What do I think about the stability of the solution?
I rate FortiSIEM 10 out of 10 for stability.
What do I think about the scalability of the solution?
I rate FortiSIEM nine out of 10 for scalability.
How was the initial setup?
Setting up FortiSIEM is straightforward. I prefer this product in the Fortinet environment. It's easy to install and configure.
What's my experience with pricing, setup cost, and licensing?
FortiSIEM might be considered expensive in some markets. We have an international customer base, and it's affordable for a lot of them.
However, customers in some markets cannot build a suitable use case around it. But it's not because of the product. It often depends on customers' operation organization.
You also need some operation and security knowledge to make a professional management decision.
A company needs to work with the consultants and distributors who are delivering the environment and necessary support.
What other advice do I have?
I rate Fortinet FortiSIEM nine out of 10.

Programmer Data Center at a consultancy with 10,001+ employees
Lacks a level of support we'd expect to see, particularly for patching; Threat Hunting is a great feature
Pros and Cons
- "The Threat Hunting feature provides complete traffic analysis."
- "Patching is not great - we're not getting the support we'd expect."
What is our primary use case?
Our use case is for collecting logs and monitoring internet traffic through firewalls. We have Fortinet firewalls and Fortinet WAF. I'm a system programmer and we are customers of Fortinet.
What is most valuable?
I like the Threat Hunting feature which provides complete traffic analysis, like file movement and processes. It's a good feature.
What needs improvement?
We have recently faced many issues in terms of support and their turnaround time for giving support as well as their patch level. The patching is one of the significant issues we face with Fortinet SIEM. We're at the enterprise level and we're not getting the support we'd expect. They really need to bring in new features like proper dashboards and alert systems and a real-time alert system which would be beneficial for users.
For how long have I used the solution?
I've been using this solution for four years.
What do I think about the scalability of the solution?
Scalability is good; you just add extra licenses. We have 15 admin users and around 10,000 EPS.
How was the initial setup?
There are lots of issues with licensing policies like the agentless and agent-based installation. It creates a lot of issues because when we purchase the SIEM, by default, we expect most of the licenses to be in the bundle. But it's not like that. We need to purchase separate licenses for each agent and agentless system. There is also licensing with the EPS. It's quite difficult for proposing and purchasing the solution. We hire Fortinet professional services for deployment.
Which other solutions did I evaluate?
I think that QRadar and RSE are better solutions than SIEM. The interactivity, scalability, and performance are far better than Fortinet.
What other advice do I have?
My needs are not getting met with this solution so I would not recommend it to anyone and rate it four out of 10.
Which deployment model are you using for this solution?
Private Cloud

Presales IT at a tech services company with 201-500 employees
Integrates logs from different sources so that there is a common place to see and create dashboards
Pros and Cons
- "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 process of installing Fortinet FortiSIEM and the customization of the alerts take too long."
What is our primary use case?
I work in our presales department. We have three of our clients using Fortinet FortiSIEM.
The solution is useful to integrate logs from different sources so that there is a common place to see and create dashboards and the AI associated with event checking.
We have a common service desk for our customers that has three employees monitoring everything. It requires less than one person to watch the dashboards, send the alerts and call the back office during an event. The solution requires maintenance every three months to install the last stable version of the firmware.
How has it helped my organization?
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. We use VPN instead of publishing services to the world, and we closed some services that are no longer being used. Eventually, we geographically blocked some services that do not need to be published in China or the United States, for example.
What is most valuable?
FortiSIEM has been a good product. It does everything that it has promised that it can do. It has been very useful to discover new threats from the outside such as external exploits, brute-force, or password tries.
What needs improvement?
The process of installing Fortinet FortiSIEM and the customization of the alerts take too long. You need to customize the alerts that come to the dashboard so that not everything is an alert. If everything is an alert, nothing is an alert. This is a complicated process and takes time.
In future releases, I would like to see a resource for common environments like VMware and VMware/FortiGate or VMware/Check Point. The resource should discover and speed up implementation.
For how long have I used the solution?
We have been using Fortinet FortiSIEM for a year and a half.
What do I think about the stability of the solution?
Being a Linux virtual appliance, FortiSIEM is a stable platform.
What do I think about the scalability of the solution?
We are located in Uruguay, which is a small country. We have no issues with scalability because we have so few people and our IT infrastructure is quite simple.
Our customers have between 200 and 400 users of Fortinet FortiSIEM.
How are customer service and support?
I would rate the customer service and support of Fortinet FortiSIEM a four out of five. They are quite good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
Prior to FortiSIEM, we did not use SIEM. We had a log concentrator, but it did not have the ability or the AI to correlate logs like SIEM has.
We decided to implement FortiSIEM because SIEM has the ability to create logs using AI. With a log concentrator, we have all the events there, but there is no relation between them and what we have to do manually.
How was the initial setup?
The initial setup of Fortinet FortiSIEM is easy. The solution is on a virtual appliance that you download and put in the VMworld or on-premise. I would rate the ease of initial setup a five out of five.
What about the implementation team?
Deployment and implementation of FortiSIEM took three months due to the tuning and the building of the dashboards. We used Fortinet professional services for our first deployment. For the second deployment, we used our in-house team.
What was our ROI?
We are seeing very good results on a security level.
What's my experience with pricing, setup cost, and licensing?
Fortinet's products are not expensive, it is less than the competition. There are additional fees for space in the virtual environment. You require virtual space because the logs take up space on the disk. Eventually, you need to buy disks and put them in your environment or in the cloud. Without the disk, you have to turn off the device.
I would rate them a three out of five overall for pricing.
Which other solutions did I evaluate?
We did consider Sentinel in Azure because it is almost free.
What other advice do I have?
If you are considering Fortinet FortiSIEM for your organization, write down what alerts are important to you, which devices deserve to be monitored, and which logs you really need. You will need to customize all of this. If you have all of this detailed, the implementation process will be easier.
I would rate the solution an eight out of ten overall.
Which deployment model are you using for this solution?

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

They are always responding to the tickets and assisting us. You can show your customer their level of engagement. It's very impressive. Customers are happy.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
In Saudi Arabia, customers are doing Splunk or LogRhythm. In Jordan, we are using Fortinet due to the fact that it is cheaper.
There is not a huge difference between all the technology as all the partners use the same technology.
How was the initial setup?
The solution is quite simple and straightforward to set up. I'd rate it a four out of five in terms of ease of execution.
There is, for example, no need to more configuration. It's very easy. In the cloud, you just reinstall the virtual machine, its main connectors in Big Sur, and then, on the customer side, you put the small virtual machine at the connectors.
What's my experience with pricing, setup cost, and licensing?
The pricing is very good. It's reasonable and competitive. I'd rate the pricing at five out of five.
What other advice do I have?
I'd rate the solution a nine out of ten.

Effective multi-tenancy, helpful support, but interface could improve
Pros and Cons
- "Fortinet FortiSIEM's most valuable feature is the simplicity in handling multi-tenancy and the ability to switch between different clients at the same time. That was handled flawlessly."
- "The interface needs some improvements because it's a bit cumbersome when you're trying to view items. It takes some time to get used to. Additionally, sometimes the scrolling does not work."
What is our primary use case?
We are using Fortinet FortiSIEM for multi-tenant SOC service.
Fortinet FortiSIEM is deployed in our data center, and we have one collector. Each client has a collector within their environment. We set up a collector within each client's environment, and then have a VPN connection from the client's environment to our environment.
How has it helped my organization?
Fortinet FortiSIEM has helped us achieve our goal of serving multi-tenant SOC services. We're able to serve multiple clients at the same time.

What about the implementation team?
We did the deployment in-house. We had two people for the implementation.
What was our ROI?
We are using Fortinet FortiSIEM to serve clients, and we are receiving our return on investment from them.
What's my experience with pricing, setup cost, and licensing?
The price of Fortinet FortiSIEM was reasonable compared to other solutions.
There are many licenses required, such as the MSSP, Agent, and device. For the number of devices that you are monitoring, you need licenses. The license you pay per your usage. When you are onboarding more clients onto it, the license fee is for the usage. Additionally, there's the Windows Agent license that you need. If you use any Windows Agent, you receive a separate license charge.
What other advice do I have?
We started using Fortinet FortiSIEM because we were recommended to use it by a trusted source.
My advice to others would be to carefully look at the cost involved, and look closely at the licensing model. If it's a model that works for you, then great. However, it came as a surprise to us, we were told that we would be giving different licenses for the devices, and for the Windows Agent separately. We were not expecting the additional costs, it caught us off guard.
I rate Fortinet FortiSIEM a six out of ten.

We do not have plans to increase the usage of the solution at this time.
How are customer service and support?
I would rate the support of Fortinet FortiSIEM a four out of ten.
Which solution did I use previously and why did I switch?
We previously were using the Juniper STRM, but Juniper STRM is currently not available. I think that their company was taken over by IBM QRadar, this is why we have gone with FortiSIEM.
How was the initial setup?
The workload required for this software is a major challenge. It requires a huge workload in terms of CPU and memory. It requires a huge workload for the installation and for the integration with all the systems. The whole implementation took approximately six months.
What about the implementation team?
We had help from the Fortinet team for the implementation team.
What was our ROI?
We have received a return on investment by using this solution.
What's my experience with pricing, setup cost, and licensing?
The price of Fortinet FortiSIEM is a lot less when compared to other solutions.
What other advice do I have?
My advice to others thinking about implementing this solution is if your organizational budget is low, then we go for Fortinet FortiSIEM. Otherwise, if we have enough budget, I would recommend IBM QRadar and or other solutions.
I rate Fortinet FortiSIEM a six out of ten.
