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.

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.

Risk-based workflows have transformed how our teams prioritize and track critical vulnerabilities
One important area for improvement could be reporting flexibility and dashboard customization, as this would need to align with specific organizational requirements. I believe it could be better. Additionally, UI simplification and more customization around workflows and reporting would further enhance the analyst experience. Improvements in executive reporting, more customizable dashboards, and deeper workflow flexibility would enhance operational usability further. Vulcan Cyber handles scalability well in our organization. It maintains stability for visibility and remediation tracking, avoiding the need for additional storage, as it is cloud-based. It scales well in our environment, even as vulnerability data and assets grow significantly.

Quotes from Members

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

Pros

"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."
"I found the initial setup user-friendly."
"In my opinion, this is the best tool."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."
"The most valuable feature is extensibility."
"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."
"Now that the solution is onboarded, we are saving a lot of time. We're saving roughly four to ten hours a week."
"Vulcan Cyber is a very good tool."
"Out of the three solutions I've used, Vulcan Cyber is the superior option."
"The automation capabilities using the Vulcan API platform or the API feature allow me to easily automate scripts and reports and schedule them."
"The most notable aspects include having prioritization capabilities and custom scripts."
"One of the features that I find valuable is the ability to bifurcate the report according to the many options available."
"They recently upgraded their UI, which is great. It is user-friendly."
"It has allowed us to bring together multiple sources of information from different signal sources into a single point."
 

Cons

"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"We would like to see Windows-based sensors available in Qualys, as this would make the platform more versatile and support a broader range of environments."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"Their support could be improved."
"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."
"It would be extremely helpful to have a community group around the product."
"If there was a way for me to connect to the vendor directly from the application, it would be helpful."
"It was a rough year in terms of setup. I had to set it up and onboard it. It was a significant effort from my side at least."
"I would describe Vulcan Cyber's user interface as adequate, but there are gaps that need addressing."
"Improvements are needed in providing more concise details on how to apply remedies for particular vulnerabilities. I would like to have more information about the remedies for particular vulnerabilities so that we do not have to go through the CVE numbers and relevant pages to check for a particular vulnerability and its remedy."
"An important area is performance and speed, as Vulcan Cyber often lacks speed when exporting reports."
"Initially, when onboarding Vulcan Cyber, the setup and configuration was more complex than expected with a user-friendly approach. This aspect can be enhanced."
"Their support is good, but there are some flaws as well. We often encounter some issues that are not applicable to Vulcan Cyber as a whole; they apply only to us because we have customized requirements. In such cases, when we reach out with specific data and issues to their support team, they sometimes come back and say that the issues have been resolved. However, when we test to see if they have been remediated, they are still there."
 

Pricing and Cost Advice

"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"TotalCloud's price is about right where I would expect it to be."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
Information not available
"Our leadership knows better about the pricing. As per my knowledge, which might not be accurate, its price can come down."
"Its pricing is quite fair compared to what is out there in the market, especially compared to the tool from Microsoft. It is a SaaS platform that has an annual cost, so it is something that is already used by many companies. It is quite affordable."
