    For secure access to apps and business data, I recommend Cisco Duo. It offers SSO, MFA, and Passwordless access, ensuring teams can securely access business data. It is easy to customize and comes with top-tier security features. It protects business data, apps, and users.

    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
    Cisco
    • We use Cisco Duo with different type of device and application, but we never face any difficulties to integrate Cisco Duo with any of them.
    • We integrated Cisco Duo with some of our active directory and some of the OS are quite old but Cisco Duo works totally fine with them.
    • The end user application is very easy to use. We never had any complain from non tech team members of having trouble of using Cisco Duo.
    • There are several authentication methods available rather than passcode. I personally like the push notification which is always on time and quite fast.

    • 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
    Cisco
    • Should have device to device connection ability whereas internet is not met.
    • Changes of device can be sorted and easily made using a second email address or any other identification method.
    • Troubleshooting should be easy to sort out. One time, a Duo admin deleted the authentication group, and some employees were not getting push notifications. It was very hard to find out the cause. Duo should have some troubleshooting finder.
    • Sometimes push notifications are delayed, and the code does not work. At that time, we need to enroll the device again. Not sure why it happens. Duo should give reasons for the error.

    • 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).

    There are a lot of competing solutions on the market; however, Duo "just works", and there is little to no learning curve for the new members to be acclimated to it. As long as that continues I see it as the preferred option moving forward

    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.

    In the last 5+ years we've been using Duo, there may have been 1 outage that impacted us. We do receive periodic notifications of issues but, for the most part, they impact carriers or functionality that we either don't use, or do not care about.

    I have not needed direct support for Cisco Secure Access by Duo as I have not had a problem with it, but I have full confidence that the support is outstanding. It is now a core component of the corporate technology stack - a problem would mean a serious degradation in the ability of the company to function.

    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

    Documentation could have been better. I had to piece together different KB/admin guides to make certain things work and I also had to use third-party guides to get bits of information that were missing from Cisco Duo documentation. Support was also engaged multiple times to figure out an issue and after some back and forth it was usually determined that the information I needed was hidden somewhere else and had no direct correlation with the document that was linked from the platform.

    Ultimately we ended up going with Cisco Duo because we are a Cisco shop. All of our networking infrastructure, our phones, our wireless environment is Cisco based. It made logical sense to stay with a product that we already have a line of support with. With a smaller support / tech group we depend on outside Cisco support. That support is already here for us, so we stayed with a Cisco product.

    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
    Cisco
    • Cisco Duo has saved us from automated attacks on VPN. We had an instance is 2024 where our VPN was being brute force attacked, and we had several users' weak passwords compromised; however the VPN security groups, and the MFA kept the attacks from gaining access. We've since replaced our firewall with capabilities for limitations on country access for VPN, and beefed up our password complexity settings,

    • 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.
