    GFI Software
    IT works very well in the non-profit and small business space when there is a need for remote access or connecting several sites in a point to point VPN, user management and rule creation are very easy. The use of the MyKerio website for remote management also makes it easy to troubleshoot problems and make changes if technical staff are not onsite.

    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.

    • 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.

    Support Rating
    GFI Software
    Support is very slow to respond and it takes a long time to convince level 1 techs that you need to be moved up to someone more senior. I believe support is outsourced and they are graded on how few tickets they need to escalate to higher tiers so they will try to figure out a solution even if it is detrimental to the overall support 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

    We found Kerio Control to provide the most features and easiest management of all the solutions we looked at, while cost was not the lowest the value was by far the best when you considered all the factors, costs, and manhours involved in deployment and management.

    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.

    • Statefull inspection and web filtering greatly reduce malware incursions.
    • Fact it can run on standard PC hardware greatly reduces cost to implement and makes scaling much less expensive.
