    It's well suited for music students' lessons. It's well suited for online coaching, primarily through places like Zoom and more. It helps simplify things for your clients, lets you program your schedule, and allows it all to go automatically! If you are working with a senior population, it may be a little tricky for them to sign up and then really hard for them to cancel lessons. There isn't a way to go to the site and cancel. You have to pull up the confirmed email and cancel from there, but people can lose emails.

    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.

    Pros
    Calendly
    • Sync with multiple calendar types so my schedule is always current.
    • Integration with Zoom to schedule meetings, send invites, and populate my Zoom app accordingly.
    • Automatic email communication to all parties with all relevant details in a clear format.
    • Allowing team members to do the same in a way that I'm also notified of what meetings are taking place saves a lot of time in terms of coordinating to find out what other people are doing.
    • Well-designed interface that simplifies everything down to its clearest expression. Language instruction and interaction are wonderfully simple and clear.

    • 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.

    Cons
    Calendly
    • After a meeting is booked, having the ability to change the location without canceling the entire booking.
    • Being able to offer 2 different locked in locations for certain time periods of the day within the same event. So you're not having to create 2 events for the same thing, only different locations.
    • Giving users permission to create their own routing forms. We run an independent business model where our users like to have control over their subscriptions.

    • 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.

    For all reasons like workflows, UI, and the way Calendly keeps all of us engaged through the Collective forum. It's indeed undeniable that no other product covers all business needs like Calendly does. On the other side, this has also reduced the workload by enabling us to focus more on other tasks for the day

    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

    Usability
    Calendly
    Calendly is extremely easy to use for selecting times and days for meetings. From my end, it's very easy to indicate the days and times that I am available for meetings. I have used other scheduling products, but Calendly has the smoothest way of operating. I highly recommend it for scheduling meetings

    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.

    There is a lot of support for Calendly. Whenever I have had issues navigating through it, especially as a new user, I found multiple support on the web addressing my questions or concerns. There is a lot of in app informative notes accessible to users to navigate through Calendly when needed.

    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.

    This was not organized training but the videos that Duo provides to teach you how to install a particular integration are top notch.

    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.

    When I started using it, there were not many competitors in this space. I've seen some like Mixmax that seem to work well for solopreneurs or where free version might be better than Calendly's free version. I use the paid version of Calendly and it's just kept serving us well so why change?

    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.

    Return on Investment
    Calendly
    • Positive: When people want to meet, I can simply send my Calendly link and it takes less than 5 seconds to do.
    • Positive: It integrates well with Zoom, which means that by default all my appointments include Zoom information for a remote call.

    • 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,
