A True Game-Changer in Modern Network Security
What do you like best about the product?
What truly stands out about Zscaler Internet Access is how effortlessly it delivers enterprise-grade security without slowing down performance. It has completely eliminated the complexity of traditional network security by shifting protection to the cloud. With ZIA, users get secure and consistent access to the internet and SaaS applications — from any device, anywhere — without relying on VPNs or backhauling traffic through data centers. The platform’s Zero Trust model, backed by real-time threat prevention, ensures every connection is inspected and verified without compromising user experience.
What do you dislike about the product?
There’s very little to dislike. The only minor challenge is that fine-tuning advanced policies requires a bit of hands-on familiarity, but once configured, the environment runs flawlessly and needs minimal maintenance.
What problems is the product solving and how is that benefiting you?
ZIA has transformed the way we think about network security. By replacing traditional firewalls and proxies with a cloud-native model, it eliminates bottlenecks and improves speed for remote and on-premises users alike. It ensures uniform security, simplifies administration, and offers deep visibility into user activity. The overall impact has been increased user productivity, stronger data protection, and complete confidence that our organization’s internet traffic remains secure no matter where our teams are working from.
Comprehensive Security Solution with Top-Notch Performance
What do you like best about the product?
I appreciate Zscaler Internet Access for eliminating the need for hardware-based proxies, which has significantly simplified our network infrastructure and reduced complexity. The centralized management for Internet traffic across various geographic locations has made it much easier and cost-efficient. I find the diverse features extremely valuable, from cloud scalability and bandwidth control to advanced security features like DLP, firewall, antivirus, and IPS, all integrated into a single management pane. The seamless transition with professional services was smooth, and the security dashboard provides excellent visibility into our security posture, enhancing user-based security rather than relying solely on IP addresses.
What do you dislike about the product?
I couldn't find any negative thing apart from the geographical restrictions that some geographies put on the Zscaler cloud nodes because they see quite a lot of traffic coming from the same source, public subnets. Considering that this may be malicious content, some geographies tend to block it based on their RAF rules.
