Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Enforces dynamic policies and blocks risky behaviors to safeguard sensitive data
The fidelity of the signal in Microsoft Defender for Cloud Apps has been a challenge in some areas. There have been instances where the alerts generated have been false positives. A lot of work has to go into scoping and tuning the policies so that actual value can be achieved, especially when not doing outright blocks. When monitoring is the approach, it can be overwhelming for security teams to review all of the alerts and determine which ones require action. When a legitimate alert is found that requires action, the tools are available to take that direction, but it can take considerable time to determine if an alert is real or not, and that represents a problem. There is uncertainty about how well Microsoft is keeping up with the changing landscape of threats, as new artificial intelligence services and software as a service applications appear every day.
