Featured Reviews

Zuhair Hasan - PeerSpot reviewer
Manager, Information Technology Security at Nesma
Has good integration capability and provides information and events but improvement is needed in information retrieval speed
The best features are the comprehensive event collection and analysis. Once set up properly, we receive all events and information. The team analyzes our data and presents incidents to us. We can communicate with their team to escalate and resolve incidents. It has a feature we use to search for information about our environment and past incidents. This is very valuable. The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets.

Comprehensive monitoring boosts security, yet incident management features need expansion
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.

Quotes from Members

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

Pros

"The correlation rules and the user platform are most valuable."
"ClearSkies is the best for software as a service and small organizations with up to 500 employees."
"The integration capability is very good - the ClearSkies SaaS NG SIEM team is collaborative. We've integrated most of our systems, including EDR and NDR. They have agents to collect events from servers and assets."
"The interface is very easy to use. The connector in the core has FortiSIEM support from the vendor."
"The most valuable feature is the anomaly-reporting alarms."
"The most valuable feature of Fortinet FortiSIEM is the correlation of many events."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"The solution has an all-in-one approach, where we buy one product and everything our customer needs is included, without additional licenses for more functionality, and any adjustments are done very quickly and easily."
"With the help of FortiSIEM we have improved the cybersecurity posture of our clients and ours, and through the early detection of threats, it allows us to follow up on each security incident and easily communicate to asset managers about related security events, reducing remediation time."
"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."
"Analytics is the most valuable feature, and the business service summaries in the dashboards and the correlations for the SIEM are also valuable features."
 

Cons

"They can add behavior analytics and AI or machine learning technology."
"They can add behavior analytics and AI or machine learning technology. They also improve their correlation engine. In addition to collecting logs from devices, they can collect the traffic and then correlate these logs and the traffic information."
"The main issue for improvement is the platform's slowness in presenting information. Retrieving information can take a little time when clicking on something."
"Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR."
"The dashboards need to be improved."
"FortiSIEM could be better integrated with other vendors."
"The deployment of the platform took some time to set up and configure."
"The initial setup is not simple. We are having some issues with the agent installation, it is requiring several reboots."
"While AccelOps tries to be a “Jack of All”, it unfortunately is a master of none. This means that the product has poor support for some third-party security technologies, such as data loss prevention (DLP), application security testing, network forensics and deep packet inspection (DPI)."
"Customer support service could be better."
"Ease-of-use for end users that do not spend every day in the product. Also, the presentation of historical and trending data in dashboards needs to be improved immensely."
 

Pricing and Cost Advice

"Fortinet's products are not expensive, it is less than the competition."
"They have a yearly subscription."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."

"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."
"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."
