Featured Reviews

IgorPinter - PeerSpot reviewer
Director at PULSEC
Zero-trust access has improved remote security and now simplifies cloud-based firewall management
Regarding the integration part for Prisma Access by Palo Alto Networks, the integration with identity providers is pretty much good. It is basically firewall as a service, so it performs well. I completed the integration without any issues. What Palo Alto Networks can do better for Prisma Access by Palo Alto Networks is probably to have the point of presence available in more locations. The point of presence from the Serbia region has the nearest POP in Frankfurt, which is an issue since it is your gateway—when you start browsing the internet, you go through a commercial connection in Germany. They definitely need to spread the service in other countries.
Mohan Janarthanan - PeerSpot reviewer
Associate Vice President at Novac Technology Solutions
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.
