Unified vulnerability workflows have transformed how our teams prioritize and resolve critical risks
While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep. When first setting up complex, multi-layered automation rules and asset groupings, the interface can feel a little overwhelming. Having more intuitive step-by-step visualized wizards or guided templates for building complex triage workflows would make the onboarding process much smoother for new team members. Dashboard customization and reporting would definitely be on my wish list. While the default dashboards are great for a general overview, it can take a bit of manual tweaking when building highly tailored workspace views for different engineering groups. Having a more flexible drag-and-drop widget system where individual teams can prioritize exactly what metrics they see first on their layout would be a huge quality of life update. On the reporting side, the data it generates is solid, but I would like to see more granular control over formatting within the platform itself. Sometimes leadership wants data tailored in very specific ways, and currently, we occasionally have to export the data and clean it up externally to meet those exact visual preferences.

Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Quotes from Members

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

Pros

"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"I would definitely recommend it because it is easy to handle any cloud resources."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"I would rate Qualys TotalCloud ten out of ten."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"Qualys TotalCloud has improved our security posture."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
 

Cons

"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"Their customer support needs improvement."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
