We have been using Duo Security for authentication in our in-house sales operations technologies. Therefore, as a Cisco partner, we regularly recommend Cisco Duo Security to our customers to help secure their VPN environments or connectivity to business-critical systems.

Our general use cases are for multi-factor authentication for our networking and data center environment devices. We also do some SAML for our network monitoring tools with our different partners in our environment. With SAML, we use it for RADIUS and TACACS authentication.

We were really looking for two-factor authentication to secure our applications. We are basically looking for it to reduce risk.

I am in the retail space at a company with more than 2,500 employees.

It is SaaS. For VPN, we have our on-prem RADIUS servers, and there is an agent on our servers for RDP.

We have implemented it in our organization, and we also implement it for our clients. Duo Security is used to push multi-factor authentication while signing onto computers. We have integrated it with on-premises Active Directory, Azure Active Directory, and Office 365. We have also integrated Duo Security with Mimecast and Mac devices. We have a couple of other use cases, but predominantly, it is for multi-factor authentication. It verifies the identity of a user through a token or a mobile phone app.

Primarily, it was used as remote access for VPNs. It expanded our security posture, due to the increase in people working from home.

We actually partner with Duo Security. We use the API to send a step-up on your phone for granting access to normal doors. You can tap your physical fob card or any other device at the door, and then receive a push notification. Depending on the success or failure of the authentication, we can either grant or reject access at the door. So it provides two-factor authentication. We use Duo for that purpose, as well as for an API and our internal VPN.

However, with our product, we use Duo Security end-to-end. Duo Security has a blind spot when it comes to physical security. It doesn't cover scenarios where someone gains physical access to our network room, which involves different technologies outside of its scope. 

From my perspective, it can't be considered truly end-to-end in that regard. Nonetheless, Duo Security offers significant value for network security and VPN access. If we combine our product with Duo Security, then we can achieve comprehensive end-to-end security.

A colleague and I conducted some market research, where we found the solution and implemented it according to our needs. We installed the agents in our server, which communicate with Duo Security and send a prompt to our mobiles which is very convenient. We can also use the authenticator with other products and integrate it with a password reset disk. The product covers all of our needs.

When our users are connecting to our Cisco VPN, Duo effectively ensures that they are who they say they are by taking a second factor into account, such as the cell phone that was used to create their profile. To do this, it sends them a second mode of authentication, such as a PIN or push confirmation. It also geo-locks who is allowed to actually log into our systems. We have it locked to the continental United States and Puerto Rico, and one outsourcing firm that we work with.

Once you have it set up, all you really have to do is add people to a group in the active directory and send them the instructions on how to do it. If you have a lower technical user base, you may have to walk them through it. But once it's set up, it really is automatic.

Not a single person from our IT staff really needed anything other than the instructions. Of the 15 people in our test group, nobody actually needed instructions on how to use it either — beyond what I just wrote up and sent them.

As we get to the older population in our company, the less technical population, we're probably going to have to walk them through it or hold their hands a little bit.

Within our organization, there are currently 15 employees using this solution. Eventually, we will have all 221 office staff users with it set up. Still, we'll probably top out at about 80 users a day.

We will increase the overall usage as our users increase. So, if we hire another 10 people, then we'll buy another license.

We use Duo Security for multi-factor authentication.

We use it for multifactor authentication for getting in with cell phones and PCs.

We began using Duo Security just after the pandemic began. We set up the VPN for our users so that they could connect from home and use the business applications. It is a security feature that is used on your mobile device, rather than something that is fixed in the office. You can use it at any given moment, as long as you have your mobile device with you.

Prior to implementing it, they were using just a username and password. That was not secure enough, so there had to be the second level of authentication. As it is now, it is integrated with the firewall. You put in your password and it is followed by a six-digit code that needs to be entered.

We operate in the financial sector so this product is crucial for our business.

The security codes are not generated locally, or on-premises. Rather, they are generated and sent from the cloud.

It is integrated with our Check Point firewall, which is used across different departments. People can connect from anywhere, including from home, and then utilize the business applications in different departments. All of them authenticate using the same firewall.

Importantly, it's not limited to one vendor or one firewall. You can use it to connect through a primary DC and a secondary DC, even if they are different vendors.

Our primary use case is for two-factor authentication. We also use the solution to secure Microsoft Remote Desktop, VPN, and SSH connections.

We deployed the product primarily to address security concerns, for example, implementing a more secure security posture using Duo Security.

My initial deployment of the product at a previous employer was across multiple environments and business units. We were primarily an active directory shop using Windows servers and desktops and Wise desktops, all of which utilized Duo Security as their two-factor solution.

In my current environment, the tool is implemented in different forms, on-premise and in the cloud. We deploy it everywhere.

My background is in electrical engineering. I have roughly almost thirty years in the industry, mostly in telecom, but the last ten years or so in enterprise. I'm currently in Anchorage, Alaska working for an organization that's Alaska-native company, which is more or less a conglomerate of different business lines. They work on everything from government contracts with NASA to construction to oil field operations, it's a lot of different businesses. 

Our Duo Security implementation was done about a little over three and a half to four years ago. It was about six months before I joined the company. It was done in response to a breach in the company that involved compromised credentials. 

I have personally been using Duo for as long as I've been in this company, so about three years.

We use it for multi-factor authentication. That's the only use case we have now. We're not using it to its maximum capabilities but we'll use it for more functions moving forward.

I work in an institution with about 6,000 people. I'm a telecommunications engineer. I use Duo Security as my access point when working remotely. Because I'm a telecommunications engineer, I have to have access to my systems remotely, and our VPN client requires that we go through second-level verification, for which we use Duo Security. 

Ours is on-prem. We have on-prem Duo Security. We do not use cloud at this time. 

We use it citywide. I work for a city, local government, and we implemented it during the pandemic.

We support it for remote access to our network. Every city employee is required to use it, including the police and fire departments. However, it's hard to concretely say if the solution has helped reduce the risk of breaches in one way or another.
Apart from that, we focus on user education in cybersecurity and provide training to our end-user population to heighten awareness. This is in addition to the two-factor authentication, so we don't solely rely on that.

You don't need any other Cisco security products in order to use it. That's what makes it easy.

Normally, people use it for multi-factor authentication. It's an easy-to-install multi-factor authentication platform.

We use it for user logins for Windows workstations and Office 365. We have certain requirements for doing two-factor authentication.

Duo is part of a complete security package that Cisco provides. Initially, we only used Duo to secure Microsoft 365, but we now use it for other applications like VPN, terminal server access, etc.

We use it for security in general. We were looking for something that would integrate with what we already had and that would give us an extra layer of security on top of what we were doing. Since a lot of people were starting to use a lot of handheld devices and equipment at home, we wanted another layer in there.

We use Duo Security for authentication for all of our SaaS applications. We also use it for RADIUS authentication.

We use it for MFA to secure our Outlook webmail and some other applications as well. We use Duo for pretty much anything that uses MFA. 

We were looking for increased security. We wanted to make sure that the person who is trying to log in to our services is actually who they claim to be. We wanted to lock down our applications more and provide extra security.

We have some on-prem servers for the gateways and it's in the cloud as well.

Our web developers use Duo Security as a WordPress plugin to provide security for our websites.

We utilize Duo Security to mitigate phishing and other similar attack vectors in general.

We use it for two-factor authentication (2FA) for accessing our portal.

We use Duo, Client, and Umbrella. 

Our primary use case for this is for our clients to be secure.

We mostly use it for our AnyConnect VPNs and two-factor authentication.

We use it for two-factor authentication so that we're not just relying on the username and password but also on two-factor authentication, whether it's through SMS or through the application.

People use very weak passwords, so it's very easy for attackers to get in and compromise accounts. This is why we need two-factor authentication and why we are with Duo Security. It helps us to not only rely on the username and password but also implement another layer of protection. Attackers are not going to be able to compromise accounts because of the two-factor authentication.

We use Duo Security for multi-factor authentication.

We use a number of Cisco products specifically, Cisco Umbrella and Duo.

Our primary use case is to enhance our client's security and their digital security model; Secure DNS, malware protection, MFA, and MDM services for their premium devices and their office devices.

Our primary use case is multifactor authentication for our VPN users. We didn't have multifactor authentication before. After we integrated Duo Security with our systems, everyone has been using it, and it has given us peace of mind when dealing with VPNs.

We are still implementing the solution and are not in full production mode yet. We implemented Duo Security in comparison with ICE, and we use it to secure our environments. It helps us authenticate users that use our network devices.

A lot of our use cases were for customers to get their cyber insurance renewed. It was a requirement and they had to scramble to figure out a way to get multi-factor authentication in place.

We use Duo Security to level up security and access to internal systems.

It's an MFA solution, and we mainly use Duo Security for secure access to some of the servers with backup data.

Duo specifically offers good MFA functionality. We needed support for our VPN and used GlobalProtect as well as Duo for additional security.

Essentially, we use it as a two-factor authentication for our users when they are trying to log into the corporate network or another dev network that we have.

On my end, Cisco Duo suits my account needs well. The application remains in place. We generally apply Cisco Duo across various use cases. Many customers, including banks and private organizations, use it for enhanced security, particularly in financial and general security tasks.

We use Duo Security for 2FA during logins.

We use Cisco Firewalls, Cisco Umbrella, and we played a bit with Cisco Duo. The integration between has gotten better recently.

We use them for a security solution, multifactor authentication, and DNS protection.

We use Duo Security for multi-factor authentication for our VPN.

We use Duo Security for two different parts. One is for access to one of the servers, and the other one is for accessing the VPN connection.

We use it for two-factor authentication for end-user and administrator login. We wanted to secure our endpoints.

We are using it for perimeter protection.

We try to use the solution for pretty much everything that we can use with it. The tool helps us to get into our dashboard APIs, and log into Citrix, VPN, and servers. 

We wanted multi-factor authentication across a variety of platforms.

We mostly use it for multi-factor authentication with email platforms like Office 365 as well as other apps.

Duo Security provides multi-factor authentication for anything that requires multi-factor authentication. It could be our internal corporate services, such as a single sign-on portal, or applications, such as Google Cloud.

Our primary use case for Duo Security is all user access to email.

With Duo, MFA allows the network to have an authenticated user sign-on seamlessly. If someone's entering a password and their user credentials and they want to get access to the network, the Duo app will have a code that the end-user has to input, which then authenticates them. It's a second layer of security before they can access the network. Even if a third party gets your username and password, without that Duo access, they won't be able to access your network.

Duo Security is multi-factor authentication, specifically a two-factor authentication. It authenticates users so that you can know they're legitimate in the network. It can be used for mobile banking. For example, when you're doing mobile or internet banking with your phone, when it uses OTP, it is using Duo Security.

I am VP of product in our company and we are a customer of Duo Security. 

This solution provides MFA (Multifactor authentication) to protect access to the ERP system for a diverse population of employees at a public higher-education institution.

We use Duo Security to access databases, which are in the cloud. It's two-factor authentication mostly.

In my job, we are using the 365 cloud service and there is a VPN solution. We are providing solutions to other enterprise-level customers, like banks. We do not require much cloud-based security because many clients need to have solutions on-premises. We already use RSA (Rivest, Shamir, and Adelman data security).  

We wanted to try to add some other cloud security options for the VPN and so we tried this product.
