    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.

    Zscaler Private Access works really well in environments setup for FQDNs and where you know what users should/shouldn't be accessing on what ports. You can use Zscaler Private Access to figure out these kinds of features but that doesn't always mean you'll be correct. It also provides a consistent experience for users as they can access their materials anywhere. It also makes the user the last line of defense. If a user's account is compromised then the attacker has access to everything they already did. It doesn't work great in OT environments or Server based environments. Flows have to be initiated from the client and not the server for stuff to behave properly.

    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.

    • Connecting users remotely with a secure connection. I am a service desk agent who works with end users, and if there is an issue due to ZPA, it's most likely due to configuration. A really good service.
    • Logging, I believe, works well as I troubleshoot end users and can gather extra details for my network admin. IP.zscaler.com, and the debug logs are nice. Additionally, I like how it shows the App policy assigned to the user's machine ECT.

    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.

    • Needs an interface for Support Desk/Help Desk to more easily understand that the problem is a lack of an FQDN or access is not allowed due to policy, not because of a technical shortcoming in ZPA.
    • Documentation of the BC solution is not well-detailed.

    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

    When it works - it works incredibly slick. It's only L4 which seems like a downgrade of security from solutions that promote L7.

    La interfaz es intuitiva y fácil de navegar, lo que permite a los usuarios administrar sus dispositivos y acceder a las políticas sin problemas. La integración con las aplicaciones SSO y SaaS facilita aún más el proceso de acceso, mejorando la experiencia del usuario.

    The environment feels more secure, and we are seeing that users are adapting to it fast. The fact that we have tools to assist the users with their day-to-day access helps, as we can hand it off to the helpdesk without any escalations to the Network team. It is a work in progress for our agency, but we are seeing the benefits from the solution.

    Reliability and Availability

    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.

    We do not see any degradation of performance of the protected applications. There are occasional lags in receiving the push but no show stooppers.

    Support Rating
    Cisco
    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.

    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.

    ZPA is where the bulk of zero-trust access is found. While the functionality for ZIA is excellent, the policy we implement for internet access is more focused on threat prevention and not narrowly scoped access.

    So far, the only limits we've encountered were tied to our imagination. Duo's strong list of supported integrations is amazing.

    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,

    • We used to get anywhere from 30 to 50 tickets surrounding our previous VPN solution every month. We now average 3-5 tickets regarding remote connectivity, and of those, only 1 or 2 are actual issues with ZPA.
    • Using ZPA Access Policies, we can now block endpoints that have outdated security software from ever connecting to our environment. This was simply not possible with our previous solution.
    • Some of our employee base skews older and had a harder time understanding the change from VPN to Zscaler.
    • There is significantly less downtime with ZPA when compared to other VPN solutions.
