    The scenario that Avast is great would be for large companies, where it works through homeoffice. Avast would be a bad idea for the educational institution, that is, a place where it will be directed to an underage audience, but I believe that Avast is on its way to becoming a global use system, so in the future it can be used in scenarios.

    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

    • Should be able to leave in only 1 language
    • Make Avast more communicative
    • It has the possibility of leaving it our way

    • 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.

    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

    In my institution we didn't choose Avast, as they see the best for the team, that is, in this case I didn't have access to the other Avast. But in this case, I can pass on my experience with the Avast that I use. It is great, but it is necessary to improve in several aspects, such as the structure.

    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.
