Detailed observability has transformed agent monitoring and now detects hallucinations quickly
I think everything is there to be true. I do not think there is a scope for improvement in Arize AI. Everything is there. It has a steep learning curve. It takes time to see how Arize works. It is not a very basic thing where anyone can go and start doing it because it takes time. There is a steep learning curve for Arize AI. Because there are so many things in the model or in an agent, it takes time. It is not very easy to use, it takes time. It has a lot of advantages, but it takes time to learn how Arize works. As I mentioned earlier, it has a steep learning curve. It takes time to learn Arize AI, it takes time to configure, it takes time to create dashboards and monitors, and it takes time to understand the UI and determine what can I find where. It takes time to do all of that. It has a steep learning curve.

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

"Arize AI has positively impacted my organization by reducing most of our manual work, shifting us to complete automation, reducing working hours, and allowing us to focus more on accuracy with less chance of mistakes."
"One of the major improvements is that prior to using Arize AI, our agent was hallucinating and we were not aware of when it hallucinates or we had a problem in debugging."
"Our timely actions, aided by Arize AI, have allowed us to report results with over 99% accuracy, proving it quite useful."
"Arize AI has made leadership more comfortable with introducing AI features by providing better visibility into failures and reducing unexpected issues in production."
"Arize AI stands out to me because of its observability and traceability and ease of use; you can click and you are good to go, and it makes you catch bugs and issues very early before debugging while helping you monitor your models in production."
"Arize AI has positively impacted my organization as the answers are more accurate and agent quality has improved dramatically."
"In my day-to-day work, monitoring is the main focus, and while there are many other tools like Prometheus and Grafana for monitoring, for ML specific use cases, I think Arize AI is the best."
"Arize AI, with its major features similar to those platforms, is a good alternative."
"FortiSIEM and FortiSOAR, their overall solutions that are there for threat mitigation, visibility, control, et cetera, is well integrated."
"These aspects make Fortinet FortiSIEM a valuable choice."
"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 valuable feature of Fortinet FortiSIEM is the correlation of many events."
"Real-time monitoring makes life quite easy for me."
"We find the solution to be stable."
"The beautiful thing about Fortinet is that they have integrated many, many solutions."
"AccelOps gives us a greater visibility into potential data/network breach attempts with the monitoring and alerting capabilities."
 

Cons

"We mostly use Arize AI for the ML side, but in my experience, Arize AI lacks on the GenAI side."
"It has a steep learning curve."
"Arize AI can add more functions."
"More end-to-end architecture examples would be beneficial as current technical documentation is solid, but more practical examples are desired."
"I think Arize AI lacks some capabilities like a versioning system."
"I think we can improve its interface."
"The evaluation workflow lacks depth in comparison to competitors, which generally rely on traditional ML frameworks."
"Their product support, in general, is not that great. When you log a call, you don't get instant replies or if there is a bug they take ages to fix it and they ask you to hold."
"Customer support service could be better."
"There are some connectivity issues with FortiAnalyzer and FortiGate."
"We need more incidents automatically to protect our network."
"An improvement would be if FortiSIEM's licensing was based on the number of nodes rather than the EPS."
"Fortinet FortiSIEM could improve by having a signature update."
"The dashboards need 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."
 

Pricing and Cost Advice

Information not available
"The solution is available for both, perpetual and subscription licenses."
"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."
"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."
"The price of Fortinet FortiSIEM was reasonable compared to other solutions."
"Pricing is determined based on the customer's budget."
"If one is cheap and ten is expensive. I rate the tool's price as an eight out of ten. Compared with Splunk or Oracle, Fortinet is cheap."
"Fortinet FortiSIEM is not an expensive solution."
"Please be cheaper and more simplified."
