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.

Advanced analytics have strengthened privileged access security and reduced incident response time
While One Identity Defender is a strong solution overall, there are a few areas where I feel it could be improved. One area is the user interface and dashboard customization. Although it is functional, making it more modern and allowing deeper customization would improve the user experience, especially for quick monitoring. Another improvement could be in reporting flexibility. While it provides good reports, having more custom report building options and easier export features would be helpful for different compliance and manageability needs. From an integration perspective, while One Identity Defender works well with core systems, having more out-of-the-box integrations with modern cloud services and SaaS platforms would reduce the need for custom configuration. In terms of support, the overall support is good, but faster response times for critical issues and more detailed troubleshooting documentation would help teams resolve problems more efficiently.

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

"The product is reliable and easy to use."
"The best feature Cisco Duo offers is a very easy-to-use web interface."
"The Verified Duo Push feature is valuable. It gives an extra level of security beyond just the regular push."
"By deploying Duo, we have virtually eliminated the risk of direct deposit redirection as a result of credentials that have been compromised via phishing."
"Cisco Duo has improved my operational efficiency and reduced costs in areas such as authentication, IT support, and security operations, as the ability to use App Push eliminated the need for text messages and additional costs for messaging, also lowering IT support costs because of the simplicity for the end-user experience."
"The push notifications are quicker and easier than with other apps because of the convenience and reliability."
"Cisco Duo is very user-friendly."
"Being able to just use a thumbprint makes it very fast."
"We find that the product scales very well."
"If you decide to activate this solution, your infrastructure will be centered around flexibility."
"One Identity Defender has positively impacted our organization by improving overall security through the addition of MFA, which reduces the risk of unauthorized access and makes user authentication more controlled and reliable."
"It's very fast, and it's easy to use because it's integrated with Active Directory."
"One Identity Defender has good network protection."
"We have definitely seen a positive ROI from using One Identity Defender, as our security team now spends about twenty to thirty percent less time on manual log analytics and investigations because the system automatically highlights high-risk activities, and we did not need to increase team size despite growing infrastructure as the tool helps us handle more security events with the same team."
"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

"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."
"One issue I see is when the device is offline."
"I evaluate the stability and reliability of the solution as somewhat tricky. Cisco Duo Access Gateway is mostly VM-based, and while I'm not sure whether there is an on-premises hardware-based solution, having this VM-based solution can be buggy."
"I believe there are two new features. I am interested in adding auto-admin services and incorporating icons for easier navigation. This could contribute to a new business idea platform. I have seen the features, and they make things easier, resolving issues from before. The platform has been updated, and there's now another link in my platform for media access. When it comes to improvements, the UI can be more user-friendly, and there is room for easier navigation. Perhaps there could be enhancements in customization. I haven't faced issues in storage or backup, but I am open to improvements in customization functionality. It's not my environment, but I see possibilities for improvement in the deployment of funds. The addition of new features is appreciated, and for customization, it could provide more freedom for users."
"Cisco Duo can be improved, but additional features that should be included in the next release are not my area of responsibility."
"Duo Security should better organize its tile feature to organize applications better."
"Duo Security could improve by being more compatible with other vendors."
"An AI support robot or bot that provides direct answers to questions without requiring the search for facts or documents to find solutions would be an improvement."
"The login capabilities could be better."
"The only reason it is not a ten is because response time can sometimes be slower for complex or escalated cases."
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"One Identity Defender is a strong product, but there are a few areas where it can be improved."
"From an automation perspective, PKI is a bit of a debatable topic and can be improved as time demands."

Pricing and Cost Advice

"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"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."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"Our licensing fee is currently on an annual basis."
"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."
"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."
"During testing we are allowed a certain number of licenses for free."
"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."
Information not available
"I would rate it seven for the price."
"This solution won't cost much, as this would be free with the licensing from Microsoft."
