    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.

    I feel the product is very good to set up basic standards and go beyond that in many aspects. However, due to being sometimes too simple, it limits the ability to do some other complex changes. Having the ability to do both would be ideal for some, if not all, of the products within Zscaler Internet Access. A simple setup to have it stand-up, and more advanced settings for those more experienced.

    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.

    • Provides a secure VPN connection point for endpoint connectivity.
    • Provides the VPN connectivity in a fast and reliable connection state.
    • Very dependable, once connected the connection stays up and there's no fuss.
    • Very good at letting you know when you are not authenticated.
    • Very easy to authenticate and regain access when your session times out.

    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.

    • ZS CLI support to turn off ZIA and ZDX service specifically on mac.
    • Better visibility into failed posture devices, including a timeline and the reason the posture failed (This is about the Zscaler mobile portal: Enrolled devices --> Failed posture devices).

    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.

    Getting started was pretty straightforward. We can tell the product is way more robust than we are using it. It started as a replacement for previous DNS-blocking content filtering, but we're exploring how this will add value with an upcoming DLP redesign and with traffic optimization at some of our remote sites with severe bandwidth limits.

    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

    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.

    The overall user community and scope of supportability outweighed the others on our short list. Netskope was a close second, but the risk, though small, was greater than that of bringing Zscaler aboard. We were looking for a mature, well-supported, highly functional, and fine-grained solution that met all our user and information security requirements.

    Return on Investment
    Untangle
    • It's allowed us to be PCI compliant which we need to do business.
    • It's allowed us to not only be PCI compliant but follow best practice to be actually as secure as we can be.
    • 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.

    • I would say it has a very good ROI, as whenever someone can't access something, they submit a ticket to our network engineer, and within minutes, the site is safely added to ZIA with best-practice configurations. After seeing a little of the UI from the Zenith event, it seems very user-friendly to control these policies.
