Featured Reviews

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

"It's fast; the whole process takes less time compared to other tools we've used before, which is very helpful."
"Cisco Duo is so integral to our core operations that we cannot perform any task without it."
"Since we onboarded it, since we started using Cisco Duo, we have never had any operational glitch."
"The feature I like the most about Cisco Duo is that it allows us to authenticate users before they can connect to our network from outside of our company."
"What I appreciate most about Cisco Duo are the security features it brings to our network environment and machine access."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"Cisco Duo is very user-friendly."
"Cisco Duo has provided substantial value, primarily in saved time, but also in low cost because administrators do not have a significant workload with Cisco Duo."
"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."
"The public key infrastructure certificates issued by the PKI servers helped me set up good client-server authentic communications."
 

Cons

"I think we'd need more experience to learn Cisco Duo because we're just at the beginning of using it."
"I cannot think of a specific feature that should be focused on for improvement, but perhaps addressing the trouble we have when people are changing phones would help."
"Scalability could be better if the price were reduced, as scaling is quite expensive."
"The only thing I can think of to improve for tech support is to have a dedicated engineer but then I would get an engineer that has priorities in one area or another and maybe not the scope I need."
"I would like to see some features simplified, such as securing, configuring, and implementing Microsoft Remote Desktop. Other than that, the solution was rock solid throughout my time administering it."
"For the back-end, there could be a few more security features applied."
"I'm unsure how to disable the ping notification sound on my phone when using Cisco Duo. I don't know how to silence it."
"Removing the need for a password would be a positive change as well as the ability to cover all the different enterprise applications. They don't have coverage for everything."
"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."

Pricing and Cost Advice

"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."
"I haven't seen any information on the pricing in four years, so I can't comment on that."
"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."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."
"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"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."
"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."
"This solution won't cost much, as this would be free with the licensing from Microsoft."
"I would rate it seven for the price."
