In large-sized medium-sized and a small-sized organizations, it improves the ability to quickly drill down into events that occur, perform analysis, and find root cause. The most value I’ve found in it, quicker time-to-resolution.
Infrastructure Operations Manager at a computer software company with 501-1,000 employees
It provides me with operational oversight on our environment using configured dashboards and reports.
Pros and Cons
- "There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not."
- "The biggest thing that could be better is a quicker response to support cases."
How has it helped my organization?
What is most valuable?
I’ve used Accelops in multiple different capacities and at several organizations. As far as my current role, I am an operations manager, and it gives me operational oversight. There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not. Reports and Alerts help identify security risks, identify performance problems, and help in capacity planning.
What needs improvement?
The biggest thing that could be better is a quicker response to support cases.
What do I think about the stability of the solution?
As I keep the system updated it helps to keep the system stable, but it’s been extremely stable and extremely reliable.

850,671 professionals have used our research since 2012.
What do I think about the scalability of the solution?
I have scaled it out with multiple workers and collectors. It’s scaled in every direction that I would like it to, geographically and from a correlation and reporting capacity standpoint.
How are customer service and support?
I’ve had lots of different engagements with support over the years and generally I’ve had very good support, knowledgeable staff and occasionally you’ll have a weird problem, longer to resolve than some other problems; but generally speaking, the support’s been very good.
I’ve used the product for a long time so I’ve requested quite a few different features. Those features have always been added, and it’s been more or less the time they need depending on what the feature is.
How was the initial setup?
It’s not harder than any other similar product. It’s very easy to set up in the fact that they provide an OVA file that you can quickly and simply download and with a few configuration settings be on the network. There are multiple other deployment options for other hypervisors as well as bare metal deployments. More than anything the troubles come with configuring all of your log sources to send the necessary log messages. That’s true for any product, not just Accelops.
What other advice do I have?
My advice would be to come up with a game plan to figure out exactly what devices or what system to focus on. Then (once you become familiar with reporting, alerting and tuning) integrate more devices/systems into Accelops.

Good solution for security detection and response
Pros and Cons
- "Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had."
- "The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."
What is our primary use case?
My company is a partner of Fortinet FortiSIEM. We are a service provider and I take the solution from Fortinet and deploy it for my customers. We use the solution for security detection and response. This is a customer based solution, our customer's security admins and security operations use the solution, compromised of a team between three to five people.
How has it helped my organization?
Our customer did not have security monitoring in the first place. With this solution, it provided security posture management and visibility about the security landscape and threats that they had.
What is most valuable?
Fortinet FortiSIEM combines the SOC and NOC into a single solution with a single pane of glass. This feature on its own is next level and its easy to handle.
What needs improvement?
Fortinet FortiSIEM should consider converting the purchase model from a CapEX investment into a pay-per-use model. By doing this, it will be more attractive for more customers.
The product does not have Security Orchestration and Automation Response, I would recommend adding this feature.
For how long have I used the solution?
I have been using Fortinet FortiSIEM for two years.
What do I think about the stability of the solution?
Stability is very good.
What do I think about the scalability of the solution?
Fortinet FortiSIEM is scalable.
How are customer service and support?
Technical support is perfect.
How was the initial setup?
The initial setup of Fortinet FortiSIEM was easy. The deployment took a week and a half and was based on a project plan. You don't need more than two people to deploy and maintain this solution.
What about the implementation team?
We use an integrator for the deployment of Fortinet FortiSIEM.
What's my experience with pricing, setup cost, and licensing?
The price of Fortinet FortiSIEM is manageable. The cost is approximately $90,000 on an annual basis.
What other advice do I have?
Before fitting the product into your environment, make sure you have the right requirements.
I would rate Fortinet FortiSIEM a 9 out of 10.
Which deployment model are you using for this solution?
On-premises

Correlates incidents between products and notifies our SOC accordingly
Pros and Cons
- "It gives us the opportunity to generate notifications based upon rules that get triggered, and the rules could be specific to PCI, HIPAA, GIBA, NIST, and so forth."
- "The backup and recovery process for this solution needs improvement."
What is our primary use case?
We are a partner, and we use this solution to ingest our customers' syslogs data for their firewalls.
How has it helped my organization?
This solution allows us to ingest syslogs from Fortinet firewalls and other products into what we call FortiSIEM. This is a processor that correlates it with the event types and incidents. It gives us the opportunity to generate notifications based upon rules that get triggered, and the rules could be specific to PCI, HIPAA, GIBA, NIST, and so forth. All of these incidents are now correlated and sent up to a dashboard or emailed, where, as a SOC, we can review these incidents and triage the necessary resolution.
What needs improvement?
The backup and recovery process for this solution needs improvement.
I would like to see a database with more structure in terms of maintenance and ease of use. The process of creating is much simpler than that of duplication. The procedures are not proper for handling its PostgreSQL database.
For how long have I used the solution?
More than two years.
What do I think about the stability of the solution?
I would say that this solution is stable when it is configured and deployed by the Fortinet professional team.
What do I think about the scalability of the solution?
The scalability is there, and you can expand on the EPS (Events Per Second) as needed.
We do plan on selling this service to our customers that can see the benefit in it. We will probably introduce an incident response application to help triage incidents at a faster level.
How are customer service and technical support?
Technical support is very good. The people in support are excellent, and they know this product in and out. They are very quick to respond and the resolution is very quick.
How was the initial setup?
The initial setup for this solution is straightforward, although we are not yet in full production. During the past two years, while we have been implementing, we have found a lot of bugs in the software. As such, we're still not in a state where we can go into full production. For example, if you are certified for PCI then one of the standards is that you have to have proper backup recovery in place. This solution is lapsing in that area.
Two staff are required for deployment and maintenance.
What about the implementation team?
We used Fortinet consultants for the deployment.
What's my experience with pricing, setup cost, and licensing?
We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that.
Which other solutions did I evaluate?
We did evaluate Splunk before choosing this solution, but it was too much on the high end for our business model.
What other advice do I have?
We are very impressed with this product. However, they have to fix their backup and recovery procedure and provide a good DR service without charging for a secondary license.
I would rate this solution a seven and a half out of ten.

We like its visibility and flexibility. It allows us to get real-time, accurate, situational awareness of what's going on.
Pros and Cons
- "We're able to get real-timec as well as our customer networks that we're monitoring at all times."
- "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."
How has it helped my organization?
We're able to get real-timec as well as our customer networks that we're monitoring at all times.
What is most valuable?
- Visibility
- Flexibility
What 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. I need to be able to understand what my situational awareness is by looking at a simple graph. I've already made a specific feature request to just make it look sexier because that's what customers like to see.
What do I think about the stability of the solution?
The stability has been very good. We've had no issues with instability.
What do I think about the scalability of the solution?
What we really like about it is the ability to scale without costing an arm and a leg for us. They're highly virtualized and, as a result, we're able to deploy in a lot faster manner than shipping their metal to a location that might have to be purchased in another state or country.
How are customer service and technical support?
We have used their technical support as well as their customer service. They've always got back to us in a timely manner. We've never had an issue of being able to get to the right person. If it doesn't get to the right person, it gets escalated very fast.
Which solution did I use previously and why did I switch?
We used LogRhythm, and Accelops replaced it.
How was the initial setup?
I wasn't involved in the initial setup, but my team was.
What other advice do I have?
You always have to do your due diligence. I'm pretty sure a lot of the other competition is just as capable, however we deal with aircrafts, which is a different, unique beast. It enables us to understand an aircraft or sat-com network infrastructure, so it's not like a traditional type of log file that you have to normalize.
Some companies work with Windows desktops and servers, but we don't. Again, be sure to do your due diligence because whether Accelops is right for you depends on your use case. Make sure also that you have an MSSP model like we do so that you're able to deliver for your customers.

A scalable product that offers good UI and firewall
Pros and Cons
- "The product's initial setup phase was easy."
- "The stability of the product is an area of concern where improvements are required."
What is our primary use case?
I use the solution in my company since it provides ease of monitoring. My company uses the product to get reports for our customers and monitoring purposes, as per the customer's preferences.
What needs improvement?
At times, I have noticed that Fortinet FortiSIEM suddenly goes down, and because of this, I have to reboot the servers from the engineers. Usually, I have to restart the panel again to get the product functioning. The aforementioned area of concern has been around for a very long time, making it something where improvements are required.
The stability of the product is an area of concern where improvements are required.
ArcSight can provide a detailed report for a year in a PDF format. In Fortinet FortiSIEM, there is a need to put in manual effort to get a detailed report. In Fortinet FortiSIEM, if I get reports for a specific time frame, I have to manually narrow them down by myself, after which I will not be able to get them in a Word or PDF format, which can be challenging.
For how long have I used the solution?
I have been using Fortinet FortiSIEM for a year. My company uses the product for some of our internal purposes.
What do I think about the scalability of the solution?
It is a scalable tool. The product can handle a considerable number of customers.
At the moment, there are only two people in my company who use the solution. In the future, the number of uses may increase, especially if my company has to deal with more customers who want to use Fortinet FortiSIEM.
How are customer service and support?
Based on what I heard from my colleagues, the technical support is not bad. My colleagues directly contact the technical support for help.
How was the initial setup?
The product's initial setup phase was easy. I wasn't a part of the deployment process.
What other advice do I have?
In terms of how the tool supports our company's compliance monitoring and reporting practices, I would say that it stems from the fact that Fortinet FortiSIEM is able to serve what our company's customers want while also having the ability to offer solutions, making it quite easy for us to give the customers what they want. The fact that the solution helps my company provide the reports that my customer wants is actually nice. The tool also offers customization ability.
The features of Fortinet FortiSIEM that I find most effective for real-time security event correlation are real-time server connections, which allow me to see all the servers that are online at a particular period of time. The product also shows the threats and bifurcates them into high, medium, and low. The solution has the ability to generate reports easily. The product also provides specific solutions for any threats that are found.
The way Fortinet FortiSIEM improves my company's security posture stems from the fact that with the tool, I can see whatever is happening in real-time. In terms of security issues, if I try to see the problem or threat, then I can really dig deep into what is happening, which is a nice feature.
The tool is easy to maintain. Only two people are required to maintain the solution.
If I compare the integration capabilities of ArcSight with Fortinet FortiSIEM, I would have to say that the latter is in a better position to provide its customers with more details in terms of cybersecurity threats or if they want to compare the firewalls. Fortinet FortiSIEM is better for customers with no cybersecurity knowledge since it helps them understand the product. Fortinet FortiSIEM is better for the security of its customers.
I would ask those who plan to use the Fortinet FortiSIEM to see whether there are other solutions with which it needs to interact in their environment. Fortinet FortiSIEM is one of the best solutions I have dealt with, considering that it has a nice user interface. The update page is good and works in real time. The firewall part of the tool is good. I don't think there is anything that can cause problems for the tool's firewall. I actually liked the tool's firewall.
I rate the overall tool a nine out of ten.

Manager, Security Services at a financial services firm with 5,001-10,000 employees
We like the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation.
Pros and Cons
- "The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."
- "Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
How has it helped my organization?
There are several examples, but the flexibility in reporting and alerting has given us the ability to have numerous teams be alerted for various security situations affecting each team's responsibilities.
What is most valuable?
The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation. The logs and search engine are also valuable features.
What needs improvement?
Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome.
Additionally, lately there have been releases which have broken existing functions. This directly relates to support being an area that also needs improvement.
What do I think about the stability of the solution?
In general, the system is stable.
What do I think about the scalability of the solution?
We had to deploy several workers to keep up with event collection. This was one reason that the AO agent was developed and released -- to reduce the load on the managers and workers.
How are customer service and technical support?
Customer Service:
Customer service is mediocre, but the relationship is improving with focused attention on customers.
Technical Support:
Technical support is good.
Which solution did I use previously and why did I switch?
We were a a Cisco MARS customer and needed to replace the solution once Cisco ceased support.
How was the initial setup?
The initial setup is straightforward. There is a learning curve for the software, but overall it was up and running and collecting information in a matter of an hour post setup.
What about the implementation team?
We implemented it with out in-house team.
Which other solutions did I evaluate?
We didn't evaluate other options as this was a direct, suggested replacement to MARS.
What other advice do I have?
Watch the sizing requirements for the virtual machines and quantities needed to support the environment. Make sure you get sign-off from Accelops on proposed the configuration and load for what’s being planned on the deployment.

Cyber Security Analyst at a retailer with 1,001-5,000 employees
Has easy access to create rules, playbooks, or use cases
Pros and Cons
- "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."
- "With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk."
What is our primary use case?
We use it as our main SIEM tool for creating rules, creating alerts, monitoring, and accessing CMDB. We also use it to monitor a few more things related to writing security.
What is most valuable?
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.
What needs improvement?
With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk.
When you work with a service provider who is using FortiSIEM as a service for other clients, you cannot run more than 30 clients on one tool. You cannot onboard, which would consume more resources and would make it slower. Also, resource consumption would be high.
For how long have I used the solution?
I've been using it for a year and a half.
What do I think about the stability of the solution?
It's pretty stable. We haven't faced any critical issues with stability.
How are customer service and technical support?
We had some issues when there were a few more updates or patches, but the technical support from FortiSIEM was pretty good and got it all sorted.
What other advice do I have?
If you're using it for multi-tenant solutions, it will be pretty good, but it won't support running more than 20 clients on the same platform. It would need more resources. Even if you are implementing it for multi-tenant solutions, you would need implement fewer clients on it so that it has to use less effort.
On a scale from one to ten, I would rate it at eight.
