    I think the most important factor is that our risk has decreased significantly among staff. Our staff is well below the industry (Education) benchmark in terms of users that are "prone to phishing". We also have multiple instances over the years where employees have stopped real efforts to access data illegally or an attempt to take funds from our institution

    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
    KnowBe4
    • Phish tests can be set to various difficulty levels as staff becomes more knowledgeable in catching phish emails.
    • Automated phish tests and training save a lot of admin time. The product can also test for phone and USB stick practices.
    • The phish alert button in Outlook, along with PhishER and PhishFlip allow easy managing and response to actual phishing emails.
    • The interactive training is well designed to cover all types of phishing and safe email and phone behavior.

    • 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.

    Cons
    KnowBe4
    • Many items in the library aren't applicable to our use case, and it's sometimes difficult to filter out what I'm looking for.
    • I don't love the training dashboard, but maybe that's just a "me" thing.
    • Setting up groups can be tedious.

    No question, KnowBe4 Security Awareness Training is a great value to our organization. Properly training our users in the proper use of email and how to be aware of possible dangerous emails is incredibly important now. Also, training users in the best practices for phone calls, as well as internet browsing can prevent data or information from being stolen or exposed. Users have even benefited when using their personal devices as a result of the trainings they have received at work.

    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 training videos we have access to are high quality, and provide a wide variety. The Inside Man videos has a cult following within our organization, and has driven a much greater interest in security awareness. And KB4's willingness to negotiate pricing for us as a nonprofit has been very valuable to us as well.

    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

    The implementation went really well and KnowBe4 was there the whole time on setup to make sure things were setup correctly. The only thing we had to figure out on our own was to script users automatically being added to security groups. So that when they sync to knowBe4 from AD they are placed into the same/correct groups.

    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
    KnowBe4
    • There is really no way one can make all the needed trainings with in house resources anymore! The cost for this would be way way more than that of any platform!
    • There is no way to even calculate the damage a company would suffer in case of a cybersecurity breach! So the cost for the use of the KnowBe4 Security Awareness Training platform if minimal compared to that of a possible breach!
    • The cost of creating content for security awareness training is no longer realistic for a company. This is really no option, and it is in no way comparable to the cost of access to the training material available in the KnowBe4 Security Awareness Training platform. Also the training content needs to be constantly updated!

    • 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.
