Zscaler Internet Access - Review
What do you like best about the product?
I used this to replace traditional data security methods, and found that its direct-to-cloud approach offers improved performance. It provides strong protection against malicious activities, and I also noticed that deployments are faster and more efficient.
What do you dislike about the product?
This product is quite complex to use and requires a significant amount of training. The initial setup, including configuration, policy definition, and implementation, is very time-consuming. Additionally, the documentation is not very good, which makes the process even more challenging.
What problems is the product solving and how is that benefiting you?
The deployment process involves minimal or no hardware interference, which I find very efficient. The secure direct-to-cloud approach ensures that the entire process is protected. My important private data remains safe, and I have not experienced any data leaks.
Securing the Cloud with Zscaler: Pros, Cons, and Real-World Insights
What do you like best about the product?
I’ve been using Zscaler for a while now, and what I like most is how simple and effective it is. It’s completely cloud-based, so there’s no need to manage hardware or deal with complex VPN setups. The Zero Trust approach is a big plus because it feels much safer—users only get access to what they need, and nothing else. Customer support is generally good.
Performance-wise, it’s great. Apps like Microsoft 365 and Zoom run smoothly without the usual lag you get with traditional VPNs.

What do you dislike about the product?
One major drawback of Zscaler’s Secure Web Gateway (SWG) is the lack of activity-based controls. It mostly works on an allow-or-block model for URLs or categories, but you can’t easily define policies for specific actions, like:
Allow browsing but block downloads
Allow login but block file uploads
Allow viewing but restrict posting or commenting
Allow browsing but block downloads
Allow login but block file uploads
Allow viewing but restrict posting or commenting
What problems is the product solving and how is that benefiting you?
Zscaler helps us secure remote and hybrid teams without using old-school VPNs or hardware. It gives direct, secure access to apps through a Zero Trust model, which means less risk and no unnecessary network exposure. For us, this means stronger protection, easier policy management, and a smoother experience for apps like Microsoft 365 and Zoom
Effortless to Use and User-Friendly
What do you like best about the product?
As a long-term supplier for a major global corporation, we use Zscaler Private Access (ZPA) daily to access their internal tools and environments. The experience is a quantum leap over the traditional VPN access we use with other clients.
What do you dislike about the product?
While the daily use is smooth, when a problem does occur, it's a real pain point, especially for external users who don't have visibility into the client's internal network.
What problems is the product solving and how is that benefiting you?
Instead of granting me broad network access Zscaler allows my client to give me least-privilege access directly to the few specific applications I need to do my job.

Reliable Cloud Security, but Setup and SSL Inspection Can Be Challenging
What do you like best about the product?
Zscaler Internet Access stands out for its reliable, cloud-based security and performance that remains consistent for all users, no matter where they are located. By shifting all security functions to the cloud, it eliminates the need for traditional, often sluggish security hardware. This approach ensures a smooth and seamless experience, whether you are working in the office or remotely.
What do you dislike about the product?
What I find most challenging is the complexity involved in the initial setup and managing policies. Additionally, there are occasional instances of latency or slowdowns, particularly noticeable when full SSL inspection is enabled.
What problems is the product solving and how is that benefiting you?
Traditional security approaches required directing all user traffic back to a central corporate data center, often referred to as the "hub," using a VPN so that an on-premises firewall could inspect it. However, this method becomes ineffective when users are distributed across various locations, such as remote sites or branch offices, and when applications are hosted in the cloud, like with SaaS solutions.
How ZIA makes that easy for me: ZIA is a cloud-native security stack that sits between the user and the internet. It routes all internet-bound traffic through its global cloud infrastructure for inspection before it reaches the destination.
