Unified vulnerability data has transformed risk prioritization and optimized remediation effort
The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms. It is helping quite a lot to unify all of that. It also offers good prioritization based on the EPSS or the CVSS score, as well as different other factors including Mandiant threat intelligence and similar aspects. It helps bring it all into one big picture instead of different silos of vulnerabilities. The integrations make my job easier because I can connect my other tools, which is the most important part of this tool to bring in all the vulnerabilities from the different other tools. The prioritization changed it from chasing vulnerabilities or pushing colleagues to patch vulnerabilities to providing colleagues with their vulnerabilities and requesting remediation and patching. Nucleus Security positively impacts my organization by bringing awareness to vulnerability management since we can actually determine how many vulnerabilities we have and how critical the risk is, or we can quantify the risk overall for the company.

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.

Quotes from Members

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

Pros

"The best features that Nucleus Security offers in my experience are the unified integrations with all of the different vulnerability management platforms."
"The best part I like is the on-demand scans."
"I found the initial setup user-friendly."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"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."
"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."
 

Cons

"Nucleus Security needs a better view into exposure management, as exposure management and attack path management are missing."
"There is a lack of data segregation according to criticality or inventory."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"The price is very expensive, actually."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
