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.

Centralized policies have improved remote endpoint control and have simplified data visibility
The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

Quotes from Members

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

Pros

"I highly recommend Qualys TotalCloud to other users."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"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."
"Its excellent graphical interface makes the scanning process simple."
"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"The scalability is good as well. I would rate it ten out of ten."
"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."
"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 say Tanium is the best tool for vulnerability management."
"I find the inventory and compliance features of Tanium to be the most impressive."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"Tanium is highly scalable."
"Tanium's most valuable feature is its instant discovery aspect."
"Tanium is stable and it is also lightweight."
 

Cons

"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."
"The cost of Qualys TotalCloud is high and could be more competitive."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"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."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"We set a policy to block USB access. The moment a device is being set up on the network, I apply the policy, but it does not come into effect immediately."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"The problem or challenge is a pre-sales and go-to strategy for the SMB market delivered through a channel or model. It's very convoluted and vague, which leads to some confusion about the various types of modules, and the device-to-seat cost is extremely difficult to calculate."
"The solution needs to improve the reporting and tracking capabilities."
"The main issues are the network connection because different customers have issues with their networks. It's difficult implementing this type of solution because the network is the main feature in the architecture for these types of solutions. Tanium could improve by creating some network optimization."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"Our biggest issue with the solution is its lack of mobility."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"TotalCloud's price is about right where I would expect it to be."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
