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 cloud visibility has simplified compliance reporting and improved incident response
Regarding performance and speed scenarios for JupiterOne, queries sometimes take too long, especially when dealing with large datasets or complex graph relationships that can slow down significantly. There is also a steep learning curve, as J1QL, their query language, is powerful but requires time to learn. New users struggle initially, and better onboarding tutorials are needed. Rate limiting issues can be frustrating, as API rate limits sometimes cause problems. Price transparency for JupiterOne is an area for improvement. The price is not publicly listed, so you have to contact sales for smaller teams or startups, which becomes a barrier. Another issue is alert noise, as sometimes too many alerts are generated. Better filtering and prioritization are needed so that critical issues do not get lost. JupiterOne is very good when compared to other cloud asset platforms overall.

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.

Quotes from Members

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

Pros

"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"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 has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"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."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"I have definitely seen a positive return on investment from JupiterOne in a few concrete ways."
"Using JupiterOne, I have observed an increase in transaction success rates to 99% without improper data, translating to 99% time saved."
"JupiterOne helps us aggregate all those things on one single platform, allowing us to quickly identify what environment that asset lives in and what type of asset it is."
"The product’s UI is pretty decent and fast."
"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."
"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 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."
 

Cons

"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"One of the things that could be improved is the alerts. Qualys is a fantastic tool, especially with the TruRisk feature, but one challenge that most leaders face involves alert fatigue."
"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 would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"However, the compliance module has not worked well, and we have had to continue tracking our compliance manually with the tools we use."
"Regarding performance and speed scenarios for JupiterOne, queries sometimes take too long, especially when dealing with large datasets or complex graph relationships that can slow down significantly."
"You can only write Python queries in Jupiter, not other languages, like, SQL or PySpark."
"JupiterOne could improve regarding the cost, as enterprise deployment can be costly."
"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."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"TotalCloud's price is about right where I would expect it to be."
"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."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"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."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
