Review summaries and opinions

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

ROI

Sentiment score
7.3
Auth0 delivers 300% ROI, reducing password issues and development costs while enhancing security and efficiency for enterprises.
Sentiment score
7.4
Cisco Duo enhances security, boosts staff morale, saves costs, and improves operations, despite perceived productivity impacts.
I think Cisco Duo offers a good return on investment for startups, newer organizations, or those utilizing cloud-based applications.
I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system.
From my point of view, the biggest return on investment when using Cisco Duo is the security and the ease of setting it up.
 

Customer Service

Sentiment score
7.3
Auth0's customer service is praised for rapid responses and assistance, though smaller accounts face challenges in accessing support.
Sentiment score
7.5
Cisco Duo's support is highly rated for expertise and solutions, but some users note delays and improvement needs.
The support staff are engineers, not just frontline personnel, ensuring expert assistance.
Their support is excellent.
They got back to us quickly, were nice, and gave us what we needed.
Other support sections have failed miserably because of the lack of response time.
I would rate the technical service and customer support of Cisco Duo a ten out of ten.
 

Scalability Issues

Sentiment score
7.3
Auth0 offers strong scalability with mostly positive user feedback, though some faced issues resolved by a MongoDB structural update.
Sentiment score
8.1
Cisco Duo is scalable, easily integrates across sites, and supports thousands of users without disruptions, adapting to various applications.
The tool is very scalable and meets our customers' needs.
I believe Cisco Duo is very scalable because it is cloud-based.
We started out with just the basics, getting a token, and then we changed to push, and now, we have added the offline mode.
It scales easily because it is just tied into our identity provider, and it grows along with that.
 

Stability Issues

Sentiment score
8.9
Auth0 is praised by users for its stability, high availability, reliable performance, and excellent documentation with high ratings.
Sentiment score
8.4
Cisco Duo is highly stable and reliable, with minimal downtime and quick issue resolution, maintaining productivity efficiently.
When there is a bigger problem, we get notifications from Cisco Duo saying, 'Hey, we have a problem,' and that has helped us.
It is very reliable, easy to use, and I don't have too many issues with it.
There has been no downtime, crashes, or performance issues with Cisco Duo.
 

Room For Improvement

Auth0 users seek improved authorization, pricing, customization, administration flexibility, IoT integration, and enhanced Management API for user data.
Cisco Duo needs telephony credit, integration, deployment, and user interface improvements, plus better licensing, documentation, and older app compatibility.
By default, the user profile does not contain the name, first name, or address, which I would expect.
A reduction of 20-25% would be great.
Cisco should allow easier integration with third-party equipment because Cisco's own equipment is expensive.
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.
There has to be a way to make the whole process of push notifications easier, so that when I have my phone with me, I do not have to do anything.
 

Setup Cost

Enterprise users have mixed opinions on Auth0 pricing; some find it clear and valuable, others see it as costly.
Cisco Duo's pricing is competitive, flexible, straightforward, and suited for large enterprises, with premium support and moderate setup costs.
The cost of the solution itself was cost-effective enough that I didn't even need to compare it with EntraID.
The approximate cost is around eighty dollars per user.
Licensing is straightforward and convenient for higher education because student populations are included.
I am pleased that the prices remained stable after Cisco acquired the solution.
 

Valuable Features

Auth0 excels in security, scalability, and integration, offering seamless authentication with extensive customization and compliance with major standards.
Cisco Duo is praised for its versatile multi-factor authentication, integration, user-friendly interface, and adaptability to hybrid environments.
The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform.
The most valuable feature of Auth0 is its customizability.
From a management perspective, I appreciate that we can enroll or control devices on the back end for people who get a new phone and forget to handle Cisco Duo properly and need to add a new device.
The benefit of having a complete passwordless environment in our organization is that it's gotten people away from using the sticky note under their keyboard - which is a huge problem.
A valuable feature of the solution is its hybrid structure, which involves proxy agents running on-premises while other services are on the cloud.

Managing security policies effectively with seamless authentication
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. There isn't a lot of training that goes on in school districts. Email is an easy way where many people give out their credentials, so the level of protection is something that we definitely need in a school district. Cisco Duo's strong security authentication system has been easy when logging in, although the teachers don't appreciate it as much. We have it configured so users essentially just hit accept. If it sees any sort of built-in risk, then it steps up authentication. It's pretty easy. I appreciate it. I've encountered advantages with Cisco Duo in that it has stopped significant pushback from teachers. It has prevented credential sharing and unauthorized access. We've seen a huge decrease since we've rolled it out across the entire district.
