Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Advanced threat protection has reduced financial risk and improves application security visibility
The issue I have with Fortinet FortiAppSec Cloud is that the real-time analysis is not robust; I am unable to see all the logs of everything that happened, including what is passive. It only logs when there are suspicious activities, which means if something is not considered suspicious by Fortinet, I will not see the full picture. That is a disadvantage because it will not log unless it identifies an IOC or attacks, meaning I cannot see traffic information in a way that helps build more intelligence. The biggest issue I have with Fortinet FortiAppSec Cloud is that the logging is not as extensive as I would prefer. For instance, if there was an issue two days ago and Fortinet FortiAppSec Cloud did not mark it as a concern, I will not see any information about that, making it challenging to explain to customers if their request did not reach us. It hampers visibility from an API perspective. They need to enhance monitoring and logging to be more extensive and capture even passive activities. The AI integration in Fortinet FortiAppSec Cloud is still new. The generative models are good, but there is much work left to improve. It is not as intelligent as it could be; thus, enhancements around the AI co-assistant would be beneficial. Additionally, logging and monitoring need improvement as I can capture traffic and investigate offline on my Fortinet firewall, including full traffic view, but Fortinet FortiAppSec Cloud currently focuses only on security concerns, which does not give the complete picture.
