The log correlation is good
Pros and Cons
  • "FortiSIEM's log correlation is good."
  • "FortiSIEM could be better integrated with other vendors."

What is our primary use case?

FortiSIEM analyzes the logs from all the servers and firewalls.

How has it helped my organization?

FortiSIEM provides visibility into what happens on our corporate network. We can see traffic from users and detect brute force or bot attacks. It's clear in the SIEM solution. 

What is most valuable?

FortiSIEM's log correlation is good. 

What needs improvement?

FortiSIEM could be better integrated with other vendors.

885,264 professionals have used our research since 2012.

For how long have I used the solution?

This happened about one year or one year and a half.

What do I think about the stability of the solution?

We had some issues during the update. Some updates didn't install, so we opened a ticket with Forti support, but it took more time to solve.

What do I think about the scalability of the solution?

FortiSIEM scales enough for our company. After the initial deployment, we added some servers and increased the resources to enable FortiSIEM to take the logs from the servers.

How are customer service and support?

I rate Fortinet support nine out of 10. It's excellent. 

How was the initial setup?

Fortinet performed the initial setup, and it took about a week. We installed the image and integrated it with another server's Active Directory. Then we integrated it with the firewalls, routers, switches, and controller. Finally, we had to configure the policies.

What other advice do I have?

I rate Fortinet FortiSIEM eight out of 10. I would recommend FortiSIEM for corporate users, but I haven't tried any other SIEM solutions, so I have no reference for comparison. In the future, we might try another vendor with a more comprehensive solution. 

Which deployment model are you using for this solution?

On-premises

It has robust event correlation and good GUI, but their technical support should be better, and it should support more nonstandard log sources
Pros and Cons
  • "The event correlation is pretty robust. The GUI is pretty good."
  • "The event correlation is pretty robust."
  • "Their technical support is horrible. By horrible, I mean a train wreck of a disaster that has fallen off a bridge and caught fire."
  • "Their technical support is horrible. By horrible, I mean a train wreck of a disaster that has fallen off a bridge and caught fire."

What is our primary use case?

We have eight use cases installed, and we are collecting log sources from most of the relevant endpoints. We did all that configuration ourselves. So, the product didn't really have a lot to do with it.

It is deployed on a private cloud. We manage the cloud infrastructure ourselves, and its primary purpose is to monitor and protect our network devices and our own business systems, not necessarily our customer-facing services.

We are most probably on version 3. We are not on the current release.

What is most valuable?

The event correlation is pretty robust. The GUI is pretty good. 

What needs improvement?

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 out-of-the-box log ingestion for the supported devices is fine. The main issues arise when you're trying to ingest a log source that's not supported. You're left to figure it out yourself. You have to figure out the custom parsing yourself. There should be better support for nonstandard log sources. That's because unless you can ingest logs from all of your key controls, the solution will have gaps. Out of the box, this product doesn't support a lot of normal security devices that are common, and then you get into building custom parsers yourself to get it to work.

The other problem is infrastructure stability. The architecture scaling rules that the vendor provides are vastly understated. So, we constantly run into stability problems that we end up figuring out and solving by throwing more infrastructure at it because they're understating the infrastructure requirements. It is understandable that they would do that, and you see why they would do that, but it is causing no end of problems.

For how long have I used the solution?

We've been using it for about three years.

What do I think about the scalability of the solution?

Scaling is problematic because of the architecture. It is very hard to figure out the required compute, memory, and disk space because the documentation is so bad. Like any SIEM, it is very compute-heavy. So, scaling is always a problem. We've come to the conclusion that it is not scalable to the magnitude that we require.

I have two system administrators at the moment who are a part of my SOC. We have a very small operation. My SOC right now is comprised of two analysts, a senior analyst, and a manager. All of them are technical, and all of them are involved in managing this solution in one way, shape, or form.

We use the product as one of our internal controls. We have several others, which I won't get into, and we do not plan on scaling it beyond that. We have been piloting some customer-facing use cases, and we will be deprecating those, scaling them back, and moving them to the Microsoft product.

How are customer service and support?

Their technical support is really bad. Their account support and product support are fine. I would rate their technical support one out of ten.

How would you rate customer service and support?

Negative

How was the initial setup?

The initial deployment was done with the partner. Since then, we have done additional endpoints and upgrades, and we are doing all the work ourselves now. 

What about the implementation team?

We used a partner to help us with the initial setup.

What was our ROI?

We are not really tracking ROI. We just view it as a cost of business, and we are not driving any revenue from it. So, it is just a sum cost.

What's my experience with pricing, setup cost, and licensing?

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.

In terms of additional costs, we also pay for our cloud infrastructure to run it. If your log source is not supported, you're going to have to develop custom parsing. So, you're going to incur that development cost. There is also the normal day-to-day administration cost.

Which other solutions did I evaluate?

We implemented Fortinet FortiSIEM for our own use, and then we have been exploring the idea of using it for a customer-facing or a managed service provider multi-tenant SIEM. We offer managed SIEM services to our customers, and we've come to the conclusion that it is not well suited for that purpose. We are in the process of installing Microsoft Sentinel and Azure Lighthouse for a new service.

What other advice do I have?

My overall impression is that this is an SMB product. It is not a large-scale enterprise or multi-tenant product. Even though they tell you it'll do that, it is an SMB tool, and it is pretty good for that purpose. However, most institutions would not have the required in-house expertise for it. You need a dedicated, skilled technical administrator. You need your own DevOps team, which small and medium businesses generally don't have, or you can do what we did and use a partner to do the work for you.

I would caution others to fully understand the support model and talk to reference customers about it and have a solid understanding of what their internal resource needs will be to implement and support it. That's because it is complicated. Depending on the product you pick, you would need some in-house technical capabilities. For bigger companies, that's usually not a problem, but for small and medium businesses, that can be a problem.

I would rate it a six out of ten. It is suitable for its purpose. It is targeted at the SMB market. The feature function is fine. I would rate it higher if their technical support was better.

Which deployment model are you using for this solution?

Integrates well with other Fortinet solutions, has nice VR and security feature s
Pros and Cons
  • "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."
  • "FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated."
  • "FortiSIEM is not a market leader in the SIEM space."
  • "FortiSIEM is not a market leader in the SIEM space."

What is our primary use case?

We primarily use the solution for security.

What is most valuable?

Fortinet has a unique model, which they call MSSP, managed services security partner. They select a telco in a country, partner with them, and offer them the certification track. We are an MSSP partner in Pakistan. FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated.

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.

There's a VR feature that is basically segmenting these firewalls, these security devices. Using that feature, we can make a network slice for each and every enterprise customer. All of the infrastructure is deployed in our data center, yet customer uses it as if it is their own.

What needs improvement?

FortiSIEM is not a market leader in the SIEM space. In SIEM solutions, typically, our customers ask for Splunk, or they ask for Logarithm. Some legacy customers ask for IBM. This isn’t as popular. Fortinet needs to grow in that perspective. They need to become a leader in the magic quadrant of Gartner and be seen as visionary so that the top customers, the big customers, take them seriously in the SIEM space.

For how long have I used the solution?

I’ve been using the solution for more than a year now.

What do I think about the stability of the solution?

This is an absolutely stable solution. There aren’t bugs or glitches, and it doesn’t crash or freeze. It’s reliable.

What do I think about the scalability of the solution?

We don’t have users per se. We are selling it. We have just started selling it. At this point, we have more than double-digit customers onboarded who are using the services.

My understanding is that the solution is entirely scalable.

How are customer service and support?

We find technical support quite helpful. They're very responsive. They have a very good on-the-ground team in Pakistan.

How was the initial setup?

While I am responsible for the overall product owners within PTCL, within my organization, I don’t directly deal with implementation tasks.

My colleagues tell me it is easy to deal with, however.

What's my experience with pricing, setup cost, and licensing?

I can’t speak to the general cost of the solution. They have a very flexible model for partners like us, however. It is a pay-as-you-grow model.

What other advice do I have?

I’m not sure which exact version I’m using.

We are a cloud provider. Whatever we do, we sell it to our clients. We're not an enterprise, we are a public cloud provider, PTCL, and we sell to our clients.

I’d rate the solution eight out of ten.

If a company already has Fortinet devices in their network they have all the components of security of Fortinet, then it will make sense for them to consider FortiSIEM. If, however, it doesn’t have Fortinet security devices, it may be difficult to leverage.

Security tool facilitates efficient monitoring and policy customization

What is our primary use case?

I have a lot of experience working with solutions such as Fortinet FortiSIEM, FortiSOAR, and FortiGate. I have also worked with ImmuniWeb. However, I did not have the credentials or the software to work with ImmuniWeb, which is why I was searching for more information on the website to learn more about the tool.

In the company I work for, we have a partnership with Fortinet.

In my organization, I work on Fortinet FortiSIEM in the cloud.

What is most valuable?

Fortinet FortiSIEM is really user-friendly. You can filter easily, find rules, and even create new rules. I appreciate Fortinet FortiSIEM the most because it is easy to search, filter, make rules, and look for correlations and events.

For Fortinet FortiGate, it is easy to navigate through the tool itself, make policies, and look at events and logs. It is very easy to monitor on Fortinet FortiGate. I really appreciate it and believe anyone in the field can work with it easily.

For FortiSOAR, it is easy to work with playbooks and rules for approvals, and everything there is straightforward. Fortinet FortiSIEM pulls the events from FortiSOAR, processes them, and applies the playbooks. It is simple in its functions, has correlations, and offers everything needed.

I can find everything I need on Fortinet FortiSIEM. The filters, trends, and dashboard make it easy to use. The database, alerts, and customer service are excellent as well.

What needs improvement?

Regarding Fortinet FortiSIEM, I cannot identify any specific areas for improvement because I can find everything I need. For the time being, I cannot find a real point for improvement. Everything is working great on Fortinet FortiSIEM.

For how long have I used the solution?

I have experience with Fortinet FortiSIEM for almost six months.

How are customer service and support?

For Cortex XDR from Palo Alto, it rates 10 out of 10. Everything is excellent with XDR and the technical support is exceptional.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have worked with Splunk and QRadar SIEM tools, but I prefer Fortinet FortiSIEM the most.

What's my experience with pricing, setup cost, and licensing?

I am not familiar with the price and cost of Fortinet FortiSIEM. I cannot tell you if it is high, expensive, or low. However, I can say that it is cost-effective as it provides everything needed.

Which other solutions did I evaluate?

I do not have relevant experience with tools such as Acunetix, Synopsys, Invicti, Snyk, Prolexic, AWS Shield, or Global Accelerator.

What other advice do I have?

I wish to remain anonymous, with no names for my company or myself. I prefer written communication rather than voice-based.

Based on my experience, I would rate this solution 9 or 10 out of 10.

Which deployment model are you using for this solution?

Pros and Cons
  • "Fortinet FortiSIEM provides good detection against advanced threats."
  • "The solution's interface could be modernized and improved."

What is our primary use case?

We use the solution to monitor events and logs. It gives us a very powerful view of what is going on. We can configure it to send notifications of any malicious detection because it is based on an ML (machine learning) algorithm. Aside from using the solution to monitor the logs from different sources, we can also get detections because it has strong machine learning capability.

What is most valuable?

Fortinet FortiSIEM provides good detection against advanced threats.

What needs improvement?

The solution's interface could be modernized and improved.

Reasonably priced with good dashboards and an easy initial setup
Pros and Cons
  • "Technical support is helpful."
  • "The best features are the dashboard and the integration between the Fortinet products, and if you use them together with FortiSOAR and FortiAnalyzer, it's better than Splunk."
  • "They need to integrate better with Cisco and Palo Alto."
  • "There are some connectivity issues with FortiAnalyzer and FortiGate."

What is our primary use case?

We are using the solution for our customers. 

What is most valuable?

The pricing is good. 

The best features are the dashboard and the integration between the Fortinet products. We can connect the nodes very easily.

The initial setup is very easy.

It's great to use both this and FortiSOAR. It makes everything better. If you use them together with Fortianalyzer, it's better than Splunk.

The solution is stable. 

It is a scalable product. 

Technical support is helpful. 

What needs improvement?

There are some connectivity issues with FortiAnalyzer and FortiGate.

They need to integrate better with Cisco and Palo Alto. 

What do I think about the stability of the solution?

The solution is very stable. It offers good reliability.

What do I think about the scalability of the solution?

We have found that it is possible to scale the solution.

How are customer service and support?

With technical support, I often direct tickets to them in terms of licensing, and within a maximum of two to three hours, the license will be active. They are very helpful. They are very responsive. 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."
  • "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."

  • "The interface needs some improvements because it's a bit cumbersome when you're trying to view items."

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 is most valuable?

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.  

What needs improvement?

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.

For how long have I used the solution?

I have been using Fortinet FortiSIEM for one year.

What do I think about the stability of the solution?

Fortinet FortiSIEM is stable.

What do I think about the scalability of the solution?

The scalability of Fortinet FortiSIEM is good.

How are customer service and support?

We have contacted the support a number of times and they were helpful.

How was the initial setup?

The initial setup of Fortinet FortiSIEM is straightforward. It took us approximately two weeks.

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.

Very easy alert setup; a good tool for analysis and for SOC
Pros and Cons
  • "Easy alert setup which enables different alerts in different categories."
  • "Fortinet support is very fast, and if I need to ask something, I'll get a response within a couple of hours."
  • "Not very good on non-API features, lacks that functionality."
  • "This solution is not very scalable if you have a lot of security events; it's focused more around smaller companies."

What is our primary use case?

We use Fortinet FortiSIEM for storage of security information and analysis, as well as for alerts from the 50-60 services that we have. All of our webs are linked to FortiSIEM. It's a form of SOC tool and data is used for identifying trends and what's happening around the networks. We're customers and end-to-end users when it comes to FortiSIEM, but for other Fortinet products we're either partners or a value-added reseller. I'm the principal cloud architect in our company. 

What is most valuable?

I think the most valuable feature is the easy alert setup, it's very important. It's quite simple to use and enables us to have different alerts in different categories. SOC is able to see all the red alerts, it's impossible to miss them. It's a good tool for analysis and for SOC. We upload all network detection tools that support FortiSIEM and can investigate for different alerts or vulnerabilities. A great feature is that you can use Python scripting for data stack. It's great for devices that don't generate a genuine local source of information. 

What needs improvement?

This solution is not very good on non-API features and lacks that functionality. We've raised multiple tickets to Fortinet about this and they are pending there. The product development hasn't been fast enough to ensure it can function on the cloud. It's excellent when you download and get the security locks but in areas like Microsoft 365, you have to fetch the security access using APIs and they don't update quickly enough. If Microsoft announces a new service today, we have to wait at least six months before FortiSIEM start supporting it. It's crucial that the API support is updated, for now FortiSIEM lacks functionality compared to its competitors.

For how long have I used the solution?


What do I think about the stability of the solution?

It's a very reliable solution, we haven't had any outages during the last year and we're using it a lot. We have over 40 people using it 24/7.

What do I think about the scalability of the solution?

This solution is not very scalable if you have a lot of security events; it's focused more around smaller companies. We've become too big for it with 48,000 devices which we are monitoring and we had to create another instance and split things. It's not perfect because it requires purchase of a second license. We use the solution all the time. 

How are customer service and technical support?

Fortinet support is very fast. If I need to ask something, I'll get a response within a couple of hours. 

How was the initial setup?

The initial setup was quite straightforward. They have good documentation and once we deployed, there were only a couple of times where we needed a little bit of support because there were delayed reactions. 

What's my experience with pricing, setup cost, and licensing?

The licensing is on an annual basis and calculated on the set up number. Of course, the licensing cost could be less but it's not too bad and is quite nicely priced. With Centreon or Splunk you just pay for the use but if we compare the cost of FortiSIEM with Splunk, it's less than half the price.

Which other solutions did I evaluate?

We took a look at IBM QRadar, which was the main competitor, and we also looked at Splunk. Splunk lost out quickly because of the cost and we ended up going with Fortinet because it was much easier to manage and implement things than QRadar and it has the Python scripting.

What other advice do I have?

If your use case suits this solution, I would recommend it. If you are a professional operator and you're into pre-investing, and not just paying per use, then FortiSIEM is one of the best options you can have.

I rate this product an eight out of 10.
