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.
It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.
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.

Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.

Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

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

Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.

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.
