When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
These sessions should be around five to ten minutes long, allowing users and partners to quickly grasp the information without disrupting their daily tasks.
The solution should be able to implement machine learning and analytics of all the logs for threat detection and protection.
If Azure Firewall can integrate identity features, it will help deliver additional next-generation capabilities.
Improvement in reporting and better visibility into network traffic would also be beneficial.
Azure Firewall could improve its reporting capabilities.
I would like the APIs to be more mature and more developed and have more options to automate threat hunting.

The most valuable feature of FortiGate is FortiView which provides proactive monitoring.
We got a firewall and gave an SSL VPN to my client to connect to their servers, after which, such kind of activities involving ransomware attacks stopped.
We have to combine multiple features and multiple products, and then we can say that this is more cost-effective and works properly to ensure the security posture of our cloud deployments.
With Azure Firewall on the cloud, you just need to subscribe to the firewall, configure it, and it will help you protect your environment.
The premium version includes all traditional firewall features, reducing the need for separate compute resources.
