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

"Since implementing Cisco Duo, it has greatly improved our operational efficiency."

"Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain."

"Cisco Duo has improved our operational efficiency and reduced costs in areas including authentication, IT support, and security operations."

"Since Duo Security provides a single place to log in for our SaaS applications, we don't have to manage user accounts and remember passwords for each specific application."

"It is very easy for users to enroll, and there are a lot of insights that we get from using the app on devices that people use to authenticate."

"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."

"Cisco Duo has made us more secure. We've managed to stop some threats with it and keep our users and devices safe."

"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."

More Cisco Duo pros

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

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

"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

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

"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."

"I think that the dashboard needs to be improved."

"An enhancement they might make is if they can log it to Splunk since they're big into Splunk. Instead of me having to go into that portal to look at things when someone is trying to log in and they forgot their password, I can look in and tell them they forgot their password or didn't respond to the prompt. That would be an improvement."

"It could be a little bit more intuitive when it comes to the sign-up process. I know they send out an email, but sometimes our users get a little confused. It could be an end-user problem, but Cisco could work on that a little."

"If I could improve Cisco Duo, I would suggest providing some notification back that the Cisco Duo system was not able to reach the remote device, because I was left in a situation where I did not know if it was actually my cell phone or something was wrong with Cisco Duo."

"Compared to other vendors, Cisco Duo is on the pricey end."

"My experience with deploying Cisco Duo was a bit rough at first, but after we got it smoothed out, it has worked ever since."

More Cisco Duo cons

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

Pricing and Cost Advice

"I rate the product pricing a seven out of ten."

"I haven't seen any information on the pricing in four years, so I can't comment on that."

"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."

"Its price is reasonable. It is not highly expensive."

"You pay per user when using this solution and the pricing is fair."

"It was very reasonable."

"During testing we are allowed a certain number of licenses for free."

"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."

More Cisco Duo pricing and cost advice

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

"I would rate it seven for the price."
