Seamless Cloud Security with Effortless Global Policy Management
What do you like best about the product?
Zscaler Internet Access provides seamless, cloud-delivered security without the need for complex on-prem infrastructure. I really appreciate the consistent performance, easy scalability, and the ability to enforce security policies globally from a single dashboard. The integration with zero-trust principles also ensures secure access regardless of user location, which is extremely useful in a hybrid or remote work environment.
What do you dislike about the product?
The initial setup and fine-tuning of policies can be time-consuming, especially for larger organizations. Troubleshooting issues sometimes requires deeper visibility than the platform immediately provides, and support responses can occasionally be slower than expected. Additionally, certain logs and analytics features could be more intuitive.
What problems is the product solving and how is that benefiting you?
Zscaler Internet Access is helping eliminate the need for traditional VPNs and perimeter-based security models. It simplifies secure remote access, reduces latency by routing traffic through local breakouts, and strengthens overall security posture with real-time threat detection. The biggest benefit is improved user productivity due to faster, more reliable access and reduced dependency on hardware appliances.
Effortless Security with Up-to-Date Intelligence
What do you like best about the product?
I really like the constant updates that Zscaler Internet Access provides because it means the service is always using the newest threat intelligence and security features without needing to patch or maintain hardware. This keeps protection current automatically. I also appreciate the control admin interface, which offers a single place to create policies, see traffic, review logs, and manage users. Instead of juggling multiple tools, it gives me a single control panel that makes changes faster and simplifies troubleshooting. Together, these make Zscaler Internet Access valuable as I spend far less time maintaining security tools and far more time enforcing clear, consistent security across the organization. Plus, the initial setup was very easy, and it pairs well with identity providers and endpoint agents.
What do you dislike about the product?
A few rough edges tend to show up with Zscaler Internet Access. Traffic logs can feel too high-level when trying to debug subtle issues, requiring more digging to stitch together the full path of a request. A more unified end-to-end trace view would make troubleshooting smoother. The policy engine is powerful but can get dense when rules stack, making it easy to create overlapping or conflicting rules. A built-in policy conflict checker would save mental bandwidth.
What problems is the product solving and how is that benefiting you?
I use Zscaler Internet Access to control and protect my internet flow, limiting unwanted access. The constant updates and admin interface make it valuable by maintaining up-to-date protection and simplifying policy management, saving me time and effort in maintaining and enforcing organization-wide security.
Excellent Security Solution for Upgrading Protection
What do you like best about the product?
1. Comprehensive Security Everywhere Zscaler decouples security from the physical office. Whether a user is at the headquarters, at a coffee shop, or working from home, they get the same level of protection. It eliminates the need for VPNs just to browse the internet securely.
2. Zero Infrastructure Maintenance (SaaS) Since ZIA is 100% cloud-based, there is no hardware to buy, patch, or upgrade. You don't need to manage physical firewall boxes at every branch office.

What do you dislike about the product?
1. High Cost Zscaler is a premium product. It is generally more expensive than traditional firewall solutions or basic web filters. The licensing model is per-user, which can get costly for large organizations with many features enabled.
2. Complex Deployment While you don't manage hardware, configuring the policies in the cloud can be complex. Setting up SSL inspection properly is difficult because it requires installing certificates on all devices; otherwise, it breaks many applications.

What problems is the product solving and how is that benefiting you?
The "Backhauling" Problem
The Problem: In traditional networks, traffic from remote users or branch offices is routed back to the corporate headquarters (via MPLS or VPN) to be scanned by a central firewall before going out to the internet. This is called "hair-pinning" or "backhauling." It causes high latency (slowness) and requires expensive bandwidth at the HQ.

For how long have I used the solution?
We have been using it for coming up to one year now.
What do I think about the stability of the solution?
Zscaler Internet Access is really very good. I would give them a nine.
What do I think about the scalability of the solution?
It depends on Zscaler Internet Access what their focus is in the future. If they still want to grow, then they have to get more open-minded for smaller companies. With the pricing structure that they currently have, it is only for big customers.
How are customer service and support?
Zscaler Internet Access customer service is really very good. I would give them a nine.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
There is something coming up from Microsoft that is really cheap. Also, 40Sase is a solution that could be used as an alternative. There are many new offerings coming from old firewalls vendors waking up this marketplace. Zscaler Internet Access has to take care that they do not lose their position.
How was the initial setup?
It is really very easy. You only have to do the rollout of the client and then it runs by itself.
What's my experience with pricing, setup cost, and licensing?
It is only for big companies currently and they only focus on that. That is one of the problems to get into the market. Of course, it is an expensive product.
Which other solutions did I evaluate?
There is something coming up from Microsoft that is really cheap. Also, 40Sase is a solution that could be used as an alternative. There are many new offerings coming from old firewalls vendors waking up this marketplace.
What other advice do I have?
We already have complementary solutions that we are using. We are using the partnership program. I have been in the security field for around 30 years, coming from the network perimeter security area. I moved to the security part and there I am a product owner from Zscaler Internet Access. I would not think it is for smaller companies, but it is currently coming from the other side. It is coming more from the traditional firewalling side and going more and more into the cloud area. It is difficult to provide a deep view on that. I know it only from the traditional firewall area and there you had to deal with all these appliances. I gave this review a rating of nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

I did not choose Zscaler, it was picked by my IT Department and I don't like that I have to use it
What do you dislike about the product?
I find that Zscaler Internet Access significantly hinders my productivity due to its slow performance. Particularly frustrating is the delay in internet access when starting my computer or waking it from sleep mode. I often have to wait up to five minutes for Zscaler to activate, which interrupts my workflow, especially when beginning my day or returning from breaks. Additionally, the initial setup process was not straightforward, as many in my organization still struggle with it being fully operational, which disrupts routine tasks.
