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…

Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.

Quotes from Members

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

Pros

"It's a very nice solution to work with."
"One of the most valuable features is that we can combine SOC and NOC operations in the same tool. We can provide NOC and SOC services in the same tool for two separate teams. There are plenty of third-party solutions that integrate with FortiSIEM. All these solutions already have a ready integration, and we have the possibility to create a custom connector for these solutions. Its reports are also very good."
"The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install."
"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 most valuable feature of Fortinet FortiSIEM is the correlation of many events."
"The seamless integration with FortiGate is the solution's most valuable aspect."
"FortiSIEM sends an email or SMS notifications to admins when there are significant incidents. It's a highly efficient way of responding to incidents."
"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 most important feature is ArcSight's event correlation capabilities. It's powerful and easy. I also like the flex connector capability. It's easy to develop a new connector that isn't fully supported out of the box. For example, say you created a solution internally that's completely different, and it's not unsupported by the solution. You can write your own connector using the flex connector."
"It is a robust product and has multiple valuable features."
"I really like the correlation part and the way the logs are correlated. I have never faced issues with parsing in this product. I like the way it parses, and everything is so clear to me."
"We utilize ArcSight ESM for real-time threat detection in our organization. We have custom rules that we've developed on top of the WAN services, along with scheduled licensing activities."
"We have been satisfied with the support."
"Support is very good."
"The solution is pretty stable."
"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
 

Cons

"Sometimes, if there are changes made by a user on a database server, it can be difficult to get that information on the fly. I would like to see a situation where once I specify a user with the database server I need, and with the changes they have performed on that, I don't need to continue my search pattern to drill down just to get the information."
"There could be more AI features included in the product."
"The stability of the product is an area of concern where improvements are required."
"FortiSIEM could be better integrated with other vendors."
"The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products."
"FortiSIEM is a bit resource-hungry, so work should be done on hardware resource utilization to consume less hardware."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"The deployment of the platform took some time to set up and configure."
"The way that scaling is set up isn't very cost-effective."
"ArcSight ESM's UI is a little cumbersome and complex, especially for first-time and occasional users using the console manager."
"Currently lacks SOAR feature."
"The stability isn't quite perfect. We occasionally run into problems."
"The customer experience could be improved."
"The analytics feature is not reliable and needs improvement for more detailed analysis.​"
"Its search part can be improved. When I go to the console and search for a few logs or something else, it takes a lot of time. When I try to search for three days or one week, it takes too much time. This is a major area of improvement. I wanted them to include features like SOAR, threat intelligence, and automation, and they seem to have included all these features in version 7.3 or 7.4."
"The only concern is that AI needs to be integrated"
 

Pricing and Cost Advice

"Its price can be better. We are Fortinet partners, so we can get discounts, but its price can be an issue at the beginning for others. There is a licensing scheme for every case. There are three licensing schemes that we can choose from."
"Fortinet's products are not expensive, it is less than the competition."
"The tool is really expensive. For what the tool does for our team, the price is fair."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"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."
"The price is competitive."
"We bought the perpetual license, so we own the product, but there is a three-year support renewal fee for that."
"There is a license required for this solution."
"We're paying a fee for an MSSP, and the cost of the total cost of ArcSight ESM was approximately three to four million dollars a year. The price was less than similar solutions. We did not have additional fees."
"The pricing model is expensive compared to open-source alternatives."
"ArcSight can be a little bit expensive because of the area that we work in and the cost. Licensing is mostly on a yearly basis, not monthly."
"Aggregation can help a lot in pushing down licensing costs."
"Pricing is good, I'd rate the pricing a seven out of ten, with ten being low price. It's better than Splunk and IBM QRadar because their pricing is based on EPS."
"Thanks to Micro Focus's licensing model, as an MSSP, we are able to see a complete return on our investment almost immediately."
"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
