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 threat detection has improved incident response and now reduces alert fatigue
SecureWorks Taegis VDR's best features include unified detection and response, as it pulls in alerts and logs from all my different tools such as EDR, SIEM, firewall, cloud services, and Windows machines, collecting everything into one clean dashboard where I can view all these items and eliminate the need to hunt through ten dashboards to piece a threat together. I find it very easy to navigate and customize the dashboard to fit my team's needs once everything is set up, and it is very simple to view the dashboard after setup. Cloud and hybrid support is another valuable feature of SecureWorks Taegis VDR, as it supports on-premise and cloud workloads, managing endpoints and network traffic to provide centralized visibility regardless of where my assets live, whether in the cloud or on-premise. SecureWorks Taegis VDR has positively impacted my organization because of its ease of use. The positive impacts include faster incident response, as I can detect, investigate, and contain threats much faster because it shows the full attack path in one place with deeper analysis of everything, and it reduces alert fatigue by consolidating alerts into one or two high-confidence incidents, which improves analysis efficiency and morale.

Quotes from Members

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

Pros

"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"I would definitely recommend Qualys TotalCloud to other users."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"TruRisk Insights is the most important innovation they've released this year."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"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 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."
"SecureWorks Taegis VDR's best features include unified detection and response, as it pulls in alerts and logs from all my different tools such as EDR, SIEM, firewall, cloud services, and Windows machines, collecting everything into one clean dashboard where I can view all these items and eliminate the need to hunt through ten dashboards to piece a threat together."
"It is a one-stop solution for different needs with separate APIs. The product offers different solutions for different companies."
"I chose SecureWorks Taegis VDR because I trust SecureWorks, having worked with McAfee, Symantec, Trend Micro, Kaspersky, Carbon Black, Cylance, CrowdStrike, Palo Alto Cortex XDR, and more, and I would say SecureWorks Taegis VDR is outstanding among all the other vendors in terms of functionality, ease of access, and UI friendliness."
 

Cons

"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"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."
"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."
"On a scale of one to ten, I would rate Nucleus Security overall a six."
"While the platform is incredibly powerful, the initial configuration curve of Nucleus Security can be a bit steep."
"One of the main issues with Nucleus Security is its lack of reporting capability."
"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"SecureWorks Taegis VDR is very stable, though there is scope for improvement."
"There is always room for improvement in SecureWorks Taegis VDR, especially regarding user interface and navigation, as the platform is powerful but the UI can feel complex for new users."
"I would like to improve SecureWorks Taegis VDR by enhancing the dashboard to provide a holistic view with granular data."
 

Pricing and Cost Advice

"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."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"Qualys TotalCloud is expensive."
