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

"Real-time monitoring makes life quite easy for me."
"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 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."
"The most valuable feature is auto-discovery. When you send logs from any device to port 514, it helps register those devices automatically."
"The event correlation is pretty robust. The GUI is pretty good."
"The most valuable feature is the differentiator, which has a combination of not only the SOC which covers the security operations aspect, but it also includes NOC capabilities."
"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."
"Fortinet FortiSIEM has helped our organization by providing us with business monitoring."
"The most valuable features of IBM Watson for Cyber Security are ease of use and out-of-the-box reports and compliance policies. Additionally, if there are aspects that are missing IBM add them in the next release."
"The most valuable feature of this product is innovation, where the research and upgrading of technology never ends."
"The customer support is very good."
"IBM Watson for Cyber Security is very stable."
"From what I have seen so far, this is an excellent product."
 

Cons

"I would like to see easier implementation in the future."
"The way that upgrades are handled could be a bit cleaner."
"The initial setup was quite complex."
"The tool's technical team's response time is too high, and they are not available even when they know that there are many pending issues."
"The patch management on the software needs to be better."
"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."
"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)."
"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."
"In the future, I would like to see threat intelligence included."
"They need to continue to build the AI capabilities."
"This is an expensive product, so making it more cost-effective would be an improvement."
"The dashboard could improve in IBM Watson for Cyber Security."
 

Pricing and Cost Advice

"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."
"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."
"Please be cheaper and more simplified."
"Manageable, however would be better as pay as you go versus CapEX."
"Fortinet FortiSIEM is very cost-efficient compared to other SIEM solutions."
"They have a yearly subscription."
"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."
"IBM Watson for Cyber Security is very simple to license and is priced well."
"The price of this solution should be lower, although I understand why IBM charges a premium price."
