Supports seamless authentication for users across multiple organizations and personal portals

The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

The customer finds value in adopting a platform from Jira, particularly for the ease it brings to their processes, both for on-premises operations and batch processing. Their objective is to create a new customized server specifically designed for generating certificates. This server is intended for the generation of certificates, emphasizing that it is not meant for free domain replacement. The platform of choice for this purpose is Digital One, a product that offers full customization and aligns well with the customer's preference for tailored solutions. The process of certificate issuance from Microsoft's AB involves renewal or replacement every five years. However, an issue arises in that this particular certificate requires renewal annually instead of the standard five-year cycle. The challenge is attributed to personnel changes, where an administrator responsible for the process resigns within the five-year period. To address this, we seek an automated solution that operates seamlessly with a single sign-on approach, eliminating the need for user IDs or passwords. The automation involves approval and subsequent deployment without complexities. Being a partner of DigiSet, we rely on the implementer for support in service deployment, installation, and resolution of any issues that may arise.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Cisco Duo has helped my organization reduce its overall authentication-related costs."

"All features of the solution are effective, Duo supports BYOD policies by allowing users to authenticate securely from their personal devices."

"My experience with Cisco Duo's strong security authentication system has been good; it is seamless and easy to integrate, and it is flexible."

"From the front end, it's very fast and it hasn't missed a beat, so to say."

"Cisco Duo scales with the growing needs of our organization by making it easy to acquire more licensing, especially with an enterprise agreement, which allows built-in growth and minimizes worries about licensing as we expand."

"Duo Security just adds another layer; it's a great addition to the security of any network infrastructure."

"The biggest return on investment for me when using Cisco Duo is gaining time, as I don't have to look at ten different MFA apps, and I know it will work."

"Cisco Duo is so integral to our core operations that we cannot perform any task without it."

More Cisco Duo pros

"The most valuable feature is the communication based on PKI certificates."

"The public key infrastructure certificates issued by the PKI servers helped me set up good client-server authentic communications."

"I emphasize the importance of automation in Wi-Fi management, particularly in tasks such as certificate renewal. The requirement extends to the ability to generate new certificates from a local server within the data center. There is a need to establish a new server for local certificate issuance and highlights the desire for automation in the deployment process. The emphasis lies in leveraging automated solutions to streamline these operations effectively."

Cons

"Cisco Duo can be improved with better ways to set users up. Currently, we might not be doing it perfectly as we're having them email in phone numbers to get them set up with Duo Mobile. I wish there was more of a self-service option than there is currently, at least to my understanding of Duo."

"I think the prices of Cisco Duo are quite fair, but the main problem is that Microsoft Authenticator is built-in with M365, so everyone is switching to that and using it instead of Cisco Duo because it costs extra as a standalone product."

"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."

"From an administrative standpoint, I'd love to see it be a little better at remembering a device and location so that I don't have to continually authenticate. That's pretty much it."

"Its management interface should also be improved. They should also improve its update period."

"Improving Cisco Duo might involve alerting us about telephony credits when people receive texts. We hit zero at one point, and we were running around in circles without any idea until I discovered it. That's my only complaint."

"Cisco Duo is doing exactly what we need it to do, so I cannot really give a suggestion for areas that could be improved since we do not use everything that it currently offers."

"There could be improvements made to the dashboards and more integration with the rest of the Cisco ecosystem."

"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."

Pricing and Cost Advice

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

"It's a bit confusing because we're on a three-year plan with a certain number of licenses, and we've gone over that number. They told us that when we renew, they will add all these licenses. We've expanded quickly, so everyone's kind of scared because no one knows what the bill is with the long pricing cycle."

"It was very reasonable."

"Cisco has the most expensive products because market leaders tend to charge a lot."

"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."

"Duo Security is free."

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."

"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."

More Cisco Duo pricing and cost advice

"I would rate it seven for the price."

"This solution won't cost much, as this would be free with the licensing from Microsoft."
