Untangle
Untangle is very strong in the "traditional" sense of security. That means an edge appliance that either works with an existing router or is the router itself (recommended). This approach has also been adapted well to cloud environments in order to protect virtual servers and VDI workstations. As mentioned earlier, many schools are using cloud-based filtering for their 1:1 solutions for their students. This is an area where Untangle is unable to serve. Some have used an instance of Untangle in the cloud with VPN to serve their remote needs, but it is not the same as solutions that are designed for cloud-based filtering of devices without VPN.

Zscaler
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.

Pros
Untangle
  • Web Filtering is strong, and can also do application fingerprinting to allow Facebook, but not Facebook games. Secondly, a separate partition called a "rack" can be set up to give one subnet or group of users different web filtering policies than another. For example, teachers would get more freedom to browse the web than students at a school.
  • Built-in SD-WAN connectivity as part of your license. IPSEC tunnel creation is also amazingly easy.
  • Will install on any x86 hardware created in the last 5-10 years. Ram and processor requirements per user are very low.
  • Reporting is phenomenal, however you can get death by details very easily.

  • 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
Untangle
  • The full suite can be expensive for business but will be powerful enough.
  • The full suite for home or small office isn't that bad of a price but may be out of reach for most home users but remember the basics are FREE so anyone can get started with it.
  • I would like to see it promoted for mid to large businesses as I think it can handle it.

  • 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

Zscaler
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.

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.

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
Untangle
Untangle NG Firewall has a partnership with third parties to provide an amazing suite of applications. You pay for those. With free software, you have to wait for it to be updated. With Unifi, the hardware was too underpowered to do anything meaningful. I don't mind the monthly fees because these companies update quickly; they have a reputation to maintain.

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.

  • It's really presented us with a lot of flexibility in terms of how we connect to other services.
  • There is some maintenance, but it's very minimal.
