Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees
Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.

Unified visibility has strengthened zero trust decisions but reporting and skills still need work
Regarding the ability of Unified Vulnerability Management to generate customizable compliance reports, it is adequate, but sometimes you still need to be able to filter whatever the report generates to ensure accuracy and have a baseline on what the report provides. You should be able to filter and also take action on critical and non-critical reports. You get a lot of reports, but filtering them is essential. The negative side of Unified Vulnerability Management is that you need a skill set that is not readily available. You require a lot of training and personnel that understand the technology, so getting the skill set is a major issue for managing the technology.

"The best features Nucleus Security offers, in my opinion, are that it is really great in showcasing things and providing centralized vulnerability management."

"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"Based on my experience, the visibility and zero trust that Unified Vulnerability Management provides brings the biggest benefit."

Cons

"The negative side of Unified Vulnerability Management is that you need a skill set that is not readily available."
"More AI features would be welcome, and the price should be lower because it is becoming more expensive, and customers are already looking for alternatives because of the pricing."
