Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.
