Zscaler Internet Access has extremely powerful category selection and it is very easy to create your own destinations for inspection and policy exceptions (SSL exception specifically). It is also very affordable and just as powerful (if not more) than some of the other solutions I have used in the past to achieve internet security.

Pros
  • It's good at segregating networks and ensuring that you only give the access that you need to give. Especially with medical devices, you want to only give the access that they need and keep them in their own separate areas so that they can't just communicate with the rest of the network. It's also good at the border for keeping attackers out of the network.

  • The depth that Cloud App control policies can go into. Being able to control individual actions within an application, more than just all or nothing access.
  • The UX/UI design makes it really easy to navigate the portal.
  • Understanding how cloud app/url control policy gets evaluated and creating/editing existing policy is extremely straightforward.

Cons
  • I have one argument, failover scenario. It's not quite easy. Failover scenario of firewalls. It's sometimes not quite easy to know the issue. But if we open a tech case, a technical case to Cisco, Cisco will help us, it's a little bit con, but we are happy with this product.

  • Easier interface on the menus so they don't disappear.
  • Help, I'm contacting support only through the ZIA portal, but I'm unable to use the link easily.
  • Mobile interface changes.
  • The searching function for the logs is tricky and challenging to use, and the menu always pops down when trying to find the proper function.

It works really well. We can do most anything we want or need to with it, and you don’t have to have a doctorate or multiple certs to necessarily figure it out. The thing that would probably have to happen to make us switch would be if we just got priced out - Cisco’s more powerful and higher bandwidth models cost a pretty penny.

While Zscaler Internet Access (ZIA) delivers critical value in cloud security and RBI compliance, I rate renewal likelihood 7/10 due to evolving needs versus platform limitations. Below is my rationale:
Key Gaps:
1. Advanced Threat Costs:
ZIA’s add-ons (e.g., Advanced DLP, Sandboxing) incur 35%+ cost premiums – straining budgets as transaction volumes (UPI/iMobile) grow 50% YoY.
2. API Banking Scalability:
ZIA’s API rate limits throttle real-time policy sync during UPI peaks (10K+ TPS), forcing workarounds for finacle integrations.
3. RBI Future-Proofing:
Limited native support for upcoming digital rupee (CBDC) security rules requires custom development, increasing compliance overhead.

Usability
The platform is powerful and feature-rich, especially when paired with tools like Firepower Management Center (FMC) and SecureX. The policy structure is logical, and the visibility into traffic flows, threat activity, and rule hits is quite strong once you're familiar with the interface

The application is easy to install and configure on all Windows devices. To troubleshoot any internet issue, we can easily collect all the relevant logs from Zscaler and check the exact issue. The only problem is with the uninstall, as a dedicated crew needs to provide the password.

Reliability and Availability
As for the availability, in general we did not experience any issues with it, neither in situations where there's only one physical device implemented nor when there's and High Availability pair. Failover works like a charm, no complaints here, it works as it should and so far it has been highly reliable.

Support Rating
Our experience with Cisco TAC support for Cisco Secure Firewall has been very good. The support engineers are knowledgeable about the product and have many tools available to them to work "under the hood" of the firewalls or management center. When we've had equipment failures, the RMA process has been simple and straightforward.

Zscaler's ZIA support is quick and knowledgable. They respond within 1-2 hours of you submitting your ticket. They are very thorough and are typically ready to jump on a live troubleshooting session. Our ZIA platform and how we use is it unique so at times tickets can be open for weeks but we alway get quality support compared to other unrelated product support in our enterprise

Implementation Rating
Our initial implementation was aided by Cisco's professional services and was excellent. The engineer was very knowledgeable and helped us work through issues while building out our new internet security edge Part of this involved tools to migrate the firewall configuration from old to new.

Alternatives Considered
Cisco Secure Firewall works better with the Cisco ecosystem when we can utilize it and feels beefy enough when we utilize it in the data center. The Fortinet we have found are great, small cost boxes for remote offices with a better UI then Cisco Secure Firewalls. The feature set included with the firewalls feels similar from a security point of view.

Zscaler Internet Access is most akin to ZPA - we bought both at the same time to handle all traffic internally and externally. In terms of quality - I would make the statement that Zscaler Internet Access is a simpler product but that's also cause there are no App Connectors involved in that process.
