    We did look at Okta for our 2FA solution and while it did support end user 2FA, Okta did not have the feature set that Cisco Duo was offering. One of our requirements was 2FA support for custom applications. Cisco Duo had the solution and support staff to help us roll that out.

    At the time of purchasing, Azure MFA was not supported well for the applications we use. As this was quite some time ago, we will do a review probably next year to see if Azure MFA could be the successor (and cheaper) to Duo Security.

    We used Google 2F for a bit in some of our organization but found it lacking a lot of the benefits and security that we were wanting. We would rather pay a few bucks more a person a month and have peace of mind knowing we have a solid 2-Factor product connected to us.

    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.

    Microsoft 365 would be well suited for medium to large enterprises. This is where there are several hundreds or thousands of people. Since most everyone has used one of the applications the learning curve would be reduced. Another reason would be the ability to implement security measures to prevent access to sensitive data. This could justify the cost of an Enterprise license.

    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.

    • Chat with teams and the integrations with the other apps, and many more smaller ones, like to-dos, news, and the recent Outlook integration.
    • Easy embedding on SharePoint to broadcast all the content created in the different tools.
    • The office package is still robust with the good things from the past and new additions.

    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.

    • Slack is 1000x better than teams. Why put a 250 limit on a chat? Our company hasn't moved fully to channels and it's making us lose transparency. Plus, the teams channels we do have nobody is going to. 90% loss in visibility and engagement.
    • Teams for web meetings. I think the UI/UX should match Zoom which is the standard for all our customers. They don't like it when we use Teams.
    • Chats and Channels need to somehow be on one screen automatically without having to choose that view because majority of our company hasn't opened Teams Channels and only stays in chats.

    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

    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.

    Over the past 8 years of using Microsoft 365, I have noticed that they change vendors often. This always leads to a poor experience in the beginning, then levels out after some time for the company to get things worked out. As a customer, it is really frustrating because I don't have time when something isn't working to have them "look into my issue" and get back with me. They have even closed a ticket I specifically told them to keep open. Your applications are only as good as the support.

    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.

    • 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 have a lot of nonprofit users, so they have a good ROI.
    • I like the constant updates without having to purchase the software repeatedly.
    • I used to purchase each Office (insert year here) often, so the software was up to date and had the newest options and connectors. I think my return on investment would have been much better if Microsoft had updated those versions to keep them current; after all, we did pay for them.
    • Microsoft 365's offering a monthly fee or a discount for a year helps, and you can look at it as a free backup if you have everything set to back up to One Drive. (Cloud-based document filing you can access anywhere ( with an internet connection)—you Can't beat that!)
