Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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.

Strong security has protected my online accounts and keeps my access safe across platforms
In my opinion, the best feature Google Authenticator offers is the way it generates the code every one minute or thereabout, and the code keeps changing, which enhances security. I am very sure nobody can have access to my accounts without Google Authenticator. Google Authenticator has impacted my organization positively as I have first-hand assurance that nobody is breaking into any of our accounts or websites, and it saves a lot. It gives you that assurance; it makes you feel very safe. The security is top notch, and it is even amazing that it works without the internet. What is really measurable is that we do not get our things compromised now. It is more secure; it provides comfortability knowing that my account is safe, and I feel more secure.

Quotes from Members

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

Pros

"From an administrative point of view, I find Cisco Duo user-friendly because the console is very easy to use, and when it comes to the Cisco Duo agent installations, the documents are pretty clear."
"Cisco Duo just works; that is the best feature."
"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."
"The most valuable feature of Cisco Duo for us is the multi-factor authentication."
"Multifactor authentication is the most valuable feature."
"The two-factor authentication is valuable because that is the use case for which we are using it."
"Cisco Duo has been very reliable from my point of view so far, as I have not had any issues with it."
"The app has greater stability than rival solutions such as Google Authenticator, and Duo Push authentication is a valuable feature."
"Google Authenticator has helped save money, save time, and maintain reputation because of the security it provides."
"The security is top notch, and it is even amazing that it works without the internet."
"Google Authenticator has positively impacted my organization by improving security and productivity."
"The most valuable feature is the SecurID."
"RSA Authentication Manager is a robust solution that provides comprehensive protection for both on-premise and cloud-based applications."
"Easy setup, deployment, and integration in different infrastructures, including virtual ones."
"In 2005 we started with a managed authentication service for three small companies with each having approx. 250 users, and now we have 25 large enterprises/government departments with over 150,000 authenticating users and an uptime of nearly 100% over the last five years."
"The single sign-on feature is the most important."
"The product has addressed our remote access security needs while making our work force mobile thus enhancing productivity and customer service initiatives."
"It stands out as a comprehensive and adaptable solution that excels in both on-premises and cloud-based authentication, offers strong security with multi-layered authentication, and boasts a well-maintained product with reliable performance."
"It is a stable solution. I would rate the stability a nine out of ten."
 

Cons

"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."
"Regarding the pricing, setup costs, and licensing, I find that for some companies using Azure, they question why they should switch when they already have Microsoft Authenticator, which can make it commercially challenging when explaining why they need to transition to Cisco Duo."
"I rate Cisco Duo an 8 out of 10 because I deduct two points since sometimes Cisco Duo is very slow, or when users are not able to receive the code very fast."
"I don't see Cisco Duo playing a significant role in managing agentic AI identities at this moment."
"I did utilize an open-source GitHub repository that Cisco Duo had for the logs for sending off to Syslogs, but I believe that was no longer in support."
"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."
"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."
"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."
"I deduct one mark due to the lack of a backup and restore option."
"We are not planning on using the solution in the future."
"My observation over the years is that the system upgrades can be complicated and must be well planned out to address 'what if' issues, including backing off upgrades if necessary."
"The product's capabilities to protect cloud environments need improvement."
"We have encountered issue when trying to expand this particular solution for a large set of users across the country."
"Enhancing the user interface and expanding their marketing efforts in regions like Nigeria and West Africa could be beneficial."
"The price needs to be improved."
"The reporting needs to be improved, and they should be delivered by email."
"We found technical support was not very responsive to our requests for assistance."
 

Pricing and Cost Advice

"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."
"The pricing was a lot more than what we were paying for our previous solution."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"It falls in line with everything else."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"I rate the product pricing a seven out of ten."

"The solution is costly."
"The pricing is a little bit complicated because sometimes resellers are able to make prices that are too low. Our price, with a discount, is typically not as high as some of our competitors."
"As a new customer, the minimum cost would be four dollars, but you have room for negotiation, potentially bringing it down to as low as three dollars."
