    I've been using this product since it began as an open source product, I really like it and for the money, I think it's probably the best choice for most companies who need a product like this. Over the years I've seen the interface change quite a bit and sometimes I think it's a bit unclear how to do certain things and the different packages can be confusing, these are the only reasons I'm giving it a 9 instead of a 10.

    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
    Tenable
    • Setup of the internal scanner was fairly simple and straight forward.
    • An update came out for the internal scanner that allows you to add an Internal Certificate Authority for lookup.
    • Has automated reporting to keep executives and compliance departments informed.
    • Internal scanner can be configured to auto-update itself.
    • "Recast Rules" allows your organization to redefine a vulnerabilities' classification, if it is not applicable or your disagree.
    • External PCI scans allow you to remediate before submitting to Tenable.io for review.
    • Tenable.io staff was very patient and helpful. They provided some limited guidance with remediation.
    • Internal and External scans can be automated. schedule for the automated scans is very granular.

    Cons
    Tenable
    • Expensive - You do pay a slight premium for the best product in the space.
    • Asset management is difficult to work with if you have a lot of asset turnover, the license can be ''held'' for 3-6 months after the asset is gone from your environment.

    • 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.

    Overall it is good, it took a little while to understand it and figure things out but once you have a good grasp on it then, it is very good.

    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.

    Support Rating
    Tenable
    Support is usually really great at walking you through any steps you need to take when you get stuck on something. There are a few false positives and errors that have come up over the years that required their help to get through. Unfortunately, the steps required to diagnose some problems are more tedious than I think should be necessary. (IE: SQL instances can throw errors that clog up your logs because one plugin affects it in a certain way. The process to diagnose this is to watch timestamps of plugins in a log while monitoring the SQL logs at the same time and using your best guess as to what is causing it.)

    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

    Tenable.io has a comparable set of features, with excellent support and a competitive price. After less than desirable experiences with another company, we moved to Tenable and haven't looked back since.

    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
    Tenable
    • Since this is a requirement for our PCI compliance and the cost is relatively low, the ROI isn't really something we need to think too much about, Tenable's pricing is fair and affordable.

    • 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.
