Sr Security Engineer at a tech vendor with 5,001-10,000 employees
Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Easy to use with efficient vulnerability reporting and team collaboration
Use case, so all the reports from GitLeaks, DefectDojo, GitLeaks or dependency check or Trivy, they make reports, and we send this report to DefectDojo to have CVMs, Central Vulnerability Management. DefectDojo is Central Vulnerability Management. If you have a dashboard to set, we have…

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.

Quotes from Members

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

Pros

"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Its dashboards are brilliant. It provides in-depth insights."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"I would definitely recommend Qualys TotalCloud to other customers."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"With the pipeline of detection and DefectDojo, we are able to see the real vulnerabilities, and we fix them."
"The most valuable feature of Tenable Nessus is website scanning."
"The solution can scale well."
"Personally, I think Nessus is quite a good product."
"Overall Zoom is a good solution."
"I can say that I am satisfied with Tenable Nessus' support and customer relations, which is why I'm still with the solution."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"It does exactly what you expect it to do, and its pricing is great. We couldn't really ask for a better deal."
"The best features of Tenable Nessus include its compatibility with other applications such as SIEM and other apps, allowing Tenable Nessus to work smoothly with them."
 

Cons

"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"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."
"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."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"I didn't give it a ten because I would like to see simpler configuration, more customizable dashboards, and better automation and integration options."
"We need something to notify the team responsible for a product when vulnerabilities are found."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"We'd like to see the solution embrace more user-friendliness."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time."
"EQA's and dashboards should be addressed in the next release."
"Tenable Nessus provides observations but offers limited information about solutions."
"The product must be more comprehensive."
"We find that some devices aren't pinged and the scans aren't done properly."
 

Pricing and Cost Advice

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

"The cost is around $4,300 per year. Use is unlimited. You don't pay more if you want to use it for another IP."
"Its price is high for Libya. The companies here in Libya don't have the awareness of and a good budget for cybersecurity services. If you want them to go for a product, you need to provide something different. This differentiation is related to the price. They should give about 40% to 45% discount per person on the current cost."
"The price of Tenable Nessus is much more competitive versus other solutions on the market."
"The is a free version of Tenable Nessus available."
