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.

Tailored to the lifecycle management needs of banks

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

"What I most appreciate about Cisco Duo is the ease of use."

"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."

"Cisco Secure solutions are great for detecting and remediating threats across our infrastructure from end to end. The integration of Talos in SecureX is great. Everything is clear in one dashboard. You have a dashboard there, your dashboard, and now you can have one look in your dashboard and see everything. It's on one pane of glass."

"For me and my customers, the best feature is that it's very easy to integrate with the existing infrastructure. It takes a few minutes to configure it."

"Cisco Duo seems very scalable; in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."

"Cisco Duo has positively impacted my organization by helping to implement zero trust, ensuring that every user is protected against phishing or password theft, and reducing security incidents according to my records and reports for a year."

"At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process."

More Cisco Duo pros

"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

"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."

"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo."

"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."

"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."

"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."

"Cisco Duo could be improved, possibly by adding features for the healthcare space. If you're selling something to a healthcare provider, there needs to be consideration for how to launch Cisco Duo with a handheld device that is not native, where you can install the application."

"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."

"The only challenge is finding the right person sometimes. From what I've seen, being a named account is a big deal."

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 only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."

"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."

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

"The pricing was a lot more than what we were paying for our previous solution."

"It is affordable for what's coming to the table with it, but in this day and age, the cost is looked at under a microscope, and companies need to very finely define what is needed versus what is critical. In some cases, it might not be cost-effective for a company to have it. In a lot of other cases, it is the cost of doing business."

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

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

"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."

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."
