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

"Duo offers dual-factor authentication for our logins; I put in my credentials and hit go, then I get an alert on my Apple Watch and approve it, and that part is just phenomenal."
"Multifactor authentication is the most valuable feature."
"The feature I like the most about Cisco Duo is two-factor authentication, as it helps me to defend against phishing attacks and provides security for my organization."
"I appreciate the simple login feature of Cisco Duo; being able to log into your actual page and then having all your apps there is convenient."
"My experience with Cisco Duo's strong security authentication system has been good; it is seamless and easy to integrate, and it is flexible."
"The anti-phishing feature is the most valuable."
"Cisco Duo is rock solid in terms of stability and reliability."
"The feature of Cisco Duo that I prefer the most is the policies, being able to control what we need to within the policies. You can get pretty granular."
"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

"I think Cisco Duo can be improved. I found the onboarding was very difficult, even for engineers who have been using similar solutions before."
"It took me a while to figure it out. I went to every user and forced them to set it up. I might have done it the long way."
"The deployment experience was more difficult than we expected because we had some problems with the version of the OS that we have in our servers."
"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."
"Duo Security could be improved with the addition of more applications."
"The only thing I would say that may lead to a more negative experience would be allowing the engineers to help the customers whether it is a twenty-minute call or a four-hour call."
"Most of my colleagues from other companies use the Microsoft MFA solution because it's included in Office 365. Few people are considering Cisco Duo. That's the primary problem in our area. It's a solution mostly adopted by Cisco users."
"To improve Cisco Duo, wherever the team can try to reduce the number of clicks an end user needs to go through to authenticate would be good."
"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."

Pricing and Cost Advice

"It falls in line with everything else."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
"My experience with the pricing, setup cost, and licensing of Cisco Duo has been great. We've been there for 10 years. While we haven't gone through the setup part for a while, licensing is straightforward and convenient for higher education because student populations are included. So, we don't have to pay extra for it. We just pay for our knowledge workers, which has been great, and the cost is reasonable."
"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."
"Our licensing fee is currently on an annual basis."
"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"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."
"This solution won't cost much, as this would be free with the licensing from Microsoft."
"I would rate it seven for the price."
