Likelihood to Recommend
SonicWall
Based on my experience, this is a solid platform for a small to mid sized company, especially when there is someone who has IT experience, or can get outsourced IT help. I would not recommend for someone who is a technology novice. Also, this is a competent device for someone who is looking to add VPN services for remote workers.

It's best suited for a distributed remote workforce, securing internet access for users from anywhere. Suitable for highly regulated industries, such as banking and Healthcare. Not a good fit for an organisation where most of its legacy is in an on-premises environment. Bandwidth-intensive industries like media/entertainment firms.

  • Single Pane of Glass Management - Everything is very easy to access and monitor the entire environment from an internet security perspective.
  • Install Flexibility - We can and do install Zscaler Internet Access on both our client devices as well as our SD-WAN appliances and servers. This allows us to control internet security even on devices without an agent in our networks.

Cons
SonicWall
  • There are Service Bundles in SonicWall TZ that are Unlicensed and do not know why they have not be Activated - would need help to further understand benefits
  • Do not know why Standard Support is Unlicensed
  • WiFi range of TZ270W is very limited - need to add Access Points or Extended to obtain adequate coverage

Zscaler
  • The logs feel kind of lack luster
  • When issues are arising with SSL Inspection, logs show everything working despite end user experience
  • Could use some kind of global find functionality or something that would allow you to search the entire configuration for matching URLs and the like

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
SonicWall
Overall the new interface is very logical and easy to navigate. We did struggle at first coming from the older interface and finding our way around the new. But our new users found it very simple to find what they were looking for. One negative we do all struggle with is packet cpature not always being clear how its set/what is being monitored. this could do with more information on teh intial page instead of having to look for it

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.

Support Rating
SonicWall
Once you get to a competent technician the support experience is better. But I have found that the lower tiers of support are very slow to respond (like 1 email per day) and you typically have to re-explain yourself a couple times before they get it. I have not used Phone support, and that may be a better experience.

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

Alternatives Considered
SonicWall
SonicWall and WatchGuard are both fine appliances, but I am accustomed to the Barracuda NG. The Barracuda Control Center is so powerful and useful that it beats out the other two. SonicWall does a great job of dividing up firewall rules and NAT policies, but this is a preference among engineers.

Zscaler
Zscaler Intenet Access outperformed the competition due to its lightning-fast policy delivery and cross-compatibility. It is easy to track employee usage and block unnecessary websites, reducing company internet usage. Zscalar installed on every system increases cloud-based software bandwidth, decreasing user turnaround time and increasing efficiency.

Return on Investment
SonicWall
  • We have three SonicWall TZ devices and they are very helpful in a VPN set up.
  • The subscription costs for the different features has a great return on investment. It is very well worth the money.
  • The antivirus component has been very effective on the computers and servers the SonicWall TZ device protects.

Zscaler
  • Has allowed us to remove other products that were suboptimal
  • Saved us money overall by stacking it with other Zscaler products
  • Created a more secure work environment for our users through intelligent internet policies that are not needlessly restrictive while still maintaining security best practices
