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.

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…

Quotes from Members

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

Pros

"The most valuable feature is the correlation of different logs that are collected."
"We have been satisfied with the support."
"The most useful features are directories, price, and live reporting."
"It is a robust product and has multiple valuable features."
"For the typical malware or intrusion, this solution assists us by identifying the symptoms based on network traffic from the application servers."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"Stable solution with good customer service support."
"ESM has valuable features for event prediction and security analysis."
"The most valuable feature of Fortinet FortiSIEM is the user and entity behave as analytics(UEBA). This feature mixes your data and provides useful information based on the behavior of the targeted."
"The product's initial setup phase was easy."
"The most valuable features for us are the built-in reports and alerts, along with the extreme flexibility in reporting and rule generation."
"AccelOps can handle a lot of data and it's just so important to true monitoring. Also, I can create a lot of rules to detect anything I like."
"The most valuable feature is the anomaly-reporting alarms."
"We have found the most important features in Fortinet FortiSIEM to be the correlation, file utility check, latest file, and hash changes. These features are important for us."
"To add workers and even collectors is pretty easy."
"Fortinet FortiSIEM provides good detection against advanced threats."
 

Cons

"It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are."
"The initial setup is very complex. We had to architect a deployment which allowed us to incorporate an ever growing number of customers into our hosted instance of ArcSight."
"It would be nice to have it on the cloud so that you can deploy it easily, saving time and resources."
"ArcSight ESM could improve the alerts for the storage capacities or actions."
"Currently lacks SOAR feature."
"We would like the ability to easily identify either unused resources or those that are being used sub-optimally."
"The correlation engine effectively connects different events, significantly improving our detection reach. However, limitations exist with non-default alerts, where additional costs arise for integration."
"The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible."
"Its training can be improved. Its price also needs to be improved."
"Improvements include making it easier for users to create their normalizers. Fortinet FortiSIEM uses XML for normalizing and parsing, which can be tedious and time-consuming. A simpler way of using regex could be helpful."
"There could be improvements like introducing some solutions directly into FortiSIEM to avoid the need for separately purchasing additional tools like FortiStore."
"The stability of the product is an area of concern where improvements are required."
"The deployment of the platform took some time to set up and configure."
"It would be good if the solution offered even more configuration options, especially in relation to the VPN so that it continues to be a very flexible option."
"The biggest thing that could be better is a quicker response to support cases."
"Fortinet FortiSIEM could improve to extend to several locations or sites."
 

Pricing and Cost Advice

"Customers without a ton of resources to dedicate to deployment may be better served by a managed ArcSight service."
"​It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.​"
"The product licenses are inexpensive."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
"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."
"ArcSight ESM is an affordable solution, it cost approximately $200,000 for three years. This price was at a substantial discount."
"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."
"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."
"Fortinet's products are not expensive, it is less than the competition."
"The price of Fortinet FortiSIEM is a lot less when compared to other solutions."
"They have a yearly subscription."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."

"Fortinet FortiSIEM is not an expensive solution."
"There is a need to make yearly payments towards the licensing charges attached to the product. The free version license of the product is available for two months."
