Vulcan Cyber was an exposure and vulnerability risk mitigation platform, acquired by Tenable in early 2025. The product is no longer available for sale, and functionality has been integrated into the Tenable One Exposure Management platform's vulnerability solution.
For secure access to apps and business data, I recommend Cisco Duo. It offers SSO, MFA, and Passwordless access, ensuring teams can securely access business data. It is easy to customize and comes with top-tier security features. It protects business data, apps, and users.

It's really challenging at times to contend with multiple vulnerabilities on a daily basis, and having a way to make sense of what actually needs to be prioritized and what can be shifted further down the task list is extremely helpful. Because the solution suggests what your next step should be in mitigating a specific vulnerability, it helps us save time and research by enabling us to immediately take action after being informed about an issue.

We use Cisco Duo with different type of device and application, but we never face any difficulties to integrate Cisco Duo with any of them.
We integrated Cisco Duo with some of our active directory and some of the OS are quite old but Cisco Duo works totally fine with them.
The end user application is very easy to use. We never had any complain from non tech team members of having trouble of using Cisco Duo.
There are several authentication methods available rather than passcode. I personally like the push notification which is always on time and quite fast.

Should have device to device connection ability whereas internet is not met.
Changes of device can be sorted and easily made using a second email address or any other identification method.
Troubleshooting should be easy to sort out. One time, a Duo admin deleted the authentication group, and some employees were not getting push notifications. It was very hard to find out the cause. Duo should have some troubleshooting finder.
Sometimes push notifications are delayed, and the code does not work. At that time, we need to enroll the device again. Not sure why it happens. Duo should give reasons for the error.

There are a lot of competing solutions on the market; however, Duo "just works", and there is little to no learning curve for the new members to be acclimated to it. As long as that continues I see it as the preferred option moving forward

La interfaz es intuitiva y fácil de navegar, lo que permite a los usuarios administrar sus dispositivos y acceder a las políticas sin problemas. La integración con las aplicaciones SSO y SaaS facilita aún más el proceso de acceso, mejorando la experiencia del usuario.

In the last 5+ years we've been using Duo, there may have been 1 outage that impacted us. We do receive periodic notifications of issues but, for the most part, they impact carriers or functionality that we either don't use, or do not care about.
I have not needed direct support for Cisco Secure Access by Duo as I have not had a problem with it, but I have full confidence that the support is outstanding. It is now a core component of the corporate technology stack - a problem would mean a serious degradation in the ability of the company to function.

Documentation could have been better. I had to piece together different KB/admin guides to make certain things work and I also had to use third-party guides to get bits of information that were missing from Cisco Duo documentation. Support was also engaged multiple times to figure out an issue and after some back and forth it was usually determined that the information I needed was hidden somewhere else and had no direct correlation with the document that was linked from the platform.

Ultimately we ended up going with Cisco Duo because we are a Cisco shop. All of our networking infrastructure, our phones, our wireless environment is Cisco based. It made logical sense to stay with a product that we already have a line of support with. With a smaller support / tech group we depend on outside Cisco support. That support is already here for us, so we stayed with a Cisco product.

I wasn't here at the time when the company compared different vulnerability management platforms so I'm not sure on the reasoning and difference between the 2. It could be that the team went through different choices and found Vulcan to be the best fit. It's hard for me to say why Vulcan was specifically chosen

Cisco Duo has saved us from automated attacks on VPN. We had an instance is 2024 where our VPN was being brute force attacked, and we had several users' weak passwords compromised; however the VPN security groups, and the MFA kept the attacks from gaining access. We've since replaced our firewall with capabilities for limitations on country access for VPN, and beefed up our password complexity settings,

Allows much better prioritizing of which assets are most vulnerable
Allow a better understanding of what assets are actually under real threat vs. what is assumed to be vulnerable, but the real world fact is the system would be hard to reach internally, so it's not as vulnerable.
