Zscaler Zero Trust Cloud Reviews & Product Details

What I like most is how seamlessly it replaces clunky VPNs. Rather than dropping users straight onto the network, it securely connects them only to the specific apps they need, which drastically reduces the attack surface. It provides fast, reliable access for remote teams and takes a major operational burden off IT. Review collected by and hosted on G2.com.

Setup and policy management can become overwhelming, since the admin console is fairly complex and comes with a steep learning curve. When problems do come up, troubleshooting things like granular app-level access or routing delays can feel opaque and hard to pinpoint. Full SSL inspection also occasionally disrupts legitimate legacy apps or internal workflows. On top of that, the high licensing costs can really sting for smaller teams.

The ability to replace slow, legacy VPNs with direct, identity-based Zero Trust connectivity is exceptional. Zscaler securely connects users directly to authorized applications rather than placing them onto the corporate network, which completely eliminates lateral threat movement and drastically reduces our external attack surface. The centralized cloud console makes enforcing granular access policies, SSL inspection, and DLP rules seamless across all remote and hybrid endpoints without managing hardware appliances. While Zscaler sits at an enterprise premium price point, the ROI justifies the cost. It allowed us to consolidate multiple legacy point products—including standalone VPN appliances, separate web filtering gateways, and branch hardware—into a single cloud architecture. The operational hours saved on infrastructure maintenance and reduced helpdesk connectivity tickets provide clear value for the investment. Review collected by and hosted on G2.com.

The platform has a steep learning curve when it comes to policy management and troubleshooting. Because there are numerous overlapping security policies, SSL inspection rules, and posture checks, pinpointing why a specific application or developer toolchain is blocked can require digging through dense logs. Additionally, the Zscaler Client Connector (ZCC) occasionally conflicts with local network adapters or developer environments (like CLI tools failing on SSL inspection certificates), which requires ongoing admin fine-tuning and domain bypass configurations.

What I like best is how it replaces clunky traditional VPNs by connecting users directly to specific apps rather than our entire corporate network, immediately stopping threats from moving laterally. Since it is entirely cloud-native, we get consistent, global security without having to manage or update physical firewalls. Ultimately, it gives our remote workforce incredibly fast, secure access without the usual bottlenecks. Review collected by and hosted on G2.com.

What I dislike most is the steep learning curve and complexity of managing granular policies across large enterprises, which makes troubleshooting access issues tedious. The endpoint agent (Zscaler Client Connector) can also occasionally cause latency spikes or conflict with developer tools and local environments. Additionally, strict SSL inspection sometimes triggers false-positive blocks on legitimate traffic, and the modular licensing can get quite expensive as you scale features.

What I like best about Zscaler Zero Trust Cloud is the ability to secure cloud workloads without relying heavily on traditional network-based firewalls and VPNs. The centralized policy management, granular access controls, and visibility across cloud environments make it easier to enforce consistent security. I also like that it helps reduce lateral movement and attack surface while simplifying the overall security infrastructure Review collected by and hosted on G2.com.

The main thing I dislike about Zscaler Zero Trust Cloud is the complexity involved in configuration and troubleshooting. With the number of policies and security controls available, it can take time for administrators to fully understand and fine-tune the platform. Troubleshooting connectivity issues can also be challenging when logs or diagnostics don't immediately identify the root cause. In some environments, Zscaler can impact network performance or create compatibility issues with certain applications and development tools. The licensing cost can also become significant as additional features are added Review collected by and hosted on G2.com.

What I like most about Zscaler Zero Trust Cloud is that it provides strong security while still making remote work convenient. It helps protect sensitive company and employee information, gives users secure access only to the applications they need, and reduces the need for a traditional VPN. Review collected by and hosted on G2.com.

Sometimes it can be a little inconvenient when access is blocked or there are connection issues, and it may take extra steps to troubleshoot. Overall, though, I understand that those security controls are there to protect company information. It also expires 7 days Review collected by and hosted on G2.com.

What I like best about Zscaler Zero Trust Cloud is its Zero Trust security model, which provides secure access to applications without exposing the corporate network. It is cloud-native, easy to scale, and offers strong protection against cyber threats through secure web gateway, application access, and threat prevention. I also appreciate its centralized policy management, visibility into user traffic, and seamless support for remote and hybrid work environments. Review collected by and hosted on G2.com.

One drawback is that the initial deployment and policy configuration can be complex, especially for organisations with large or legacy environments. Troubleshooting access issues may require a good understanding of Zscaler policies, and there can be a learning curve for new administrators. In some cases, strict security policies may also affect application compatibility or require additional fine-tuning to avoid disrupting users. Review collected by and hosted on G2.com.

I like using the Zscaler Zero Trust Cloud because it is smooth and handy, taking just a minute or two to connect with the VPN, allowing me to quickly get back to work. I find it faster than multiple other software that do the same work. I appreciate that it builds a secure environment for me to work from anywhere without worrying about data breaches or security attacks. This gives me the option to work from home, which makes my life easier. The speed and low prerequisites are great because they let me get used to it quickly. My favorite feature is that it logs me in automatically if I've been logged out for a short time, which I love because it adds to the convenience. Review collected by and hosted on G2.com.

The time it takes to log you in after a while should be reduced a bit. Also, the Zscaler application should come forward when the laptop is restarted. Additionally, integration with Wi-Fi would be beneficial since many organizations use Ethernet for secure internet connections, while Wi-Fi is often used for remote work. This would make the service faster and eliminate the need for manual login steps. Review collected by and hosted on G2.com.

Zscaler did come with a learning curve during our implementation, especially around application setup and policy tuning, but the support team assisted us throughout that process. While Zscaler typically authenticates automatically after logging in to Windows, there are occasional times when users have to manually log back into the application, which can cause brief disruptions during the workday. This doesn’t happen often, but it has been a minor complaint within our organization. Review collected by and hosted on G2.com.
