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 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.

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

"Qualys TotalCloud fulfills all these needs."
"I would definitely recommend Qualys TotalCloud to other customers."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"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."
"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."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"Nucleus Security has fundamentally changed how we manage our vulnerability lifecycle and made our entire incident response process much more proactive, organized, and reliable."
"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 impacted my organization positively by providing a single pane view of vulnerabilities from different connectors and enabling the automation of reporting and alerting on findings that are out of due date or out of SLA."
"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"The security features are very valuable."
"The product is granular and can build complex roles compared to other EDR vendors."
"The most valuable features of this solution are the consolidation of all historical data on device endpoints, security drivers, firmware, and Software version gaps."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"I would say Tanium is the best tool for vulnerability management."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"Tanium is used for endpoint management, specifically patching and configuration management."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
 

Cons

"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."
"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."
"There is room for improvement in the support."
"The price is very expensive, actually."
"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."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"There is a lack of data segregation according to criticality or inventory."
"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."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
"Tanium’s scalability could be improved."
"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."
"The solution can give a lot of false positives."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"We had some issues with the solution's OS upgrade."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"They could improve the UI."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud is expensive."
"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."
