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

"I would rate Qualys TotalCloud ten out of ten."
"I depend heavily on the reports that I have from this tool."
"We were able to realize its benefits within 24 to 48 hours."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"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."
"The biggest strengths of Qualys TotalCloud are that it is pretty good at cloud visibility, has easy integration, and also has multi-cloud compatibility."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"With the pipeline of detection and DefectDojo, we are able to see the real vulnerabilities, and we fix them."
"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."
"The most valuable feature of Tenable Nessus is website scanning."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."
"Tenable Nessus is a very scalable solution."
"The solution is worth the cost; it's a good investment."
"I like the fact that it was not expensive. I like that it's user-friendly."
"The initial setup is very straightforward."
"The most valuable feature of Tenable Nessus is the support it provides for any new vulnerabilities quickly."
 

Cons

"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"The support is not up to the mark and seems to be overburdened."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"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"
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"We need something to notify the team responsible for a product when vulnerabilities are found."
"They have added a new Tenable Nessus Expert. That is their new product, which caters to the cloud and everything else. I am assuming that the new features and product enhancements are based on that tool set, but we haven't reviewed it yet."
"There should be a possibility to install agents on scanned machines. Tenable IO provides the capability of using local agents to check local problems, but this feature is not there in Tenable Nessus Professional. It would be nice to have something similar in Tenable Nessus Professional. We should have the capability to use local agents installed on the machines to locally check a problem."
"The price and scalability of the solution could improve."
"We'd like to see more integration potential within the solution."
"Technical support could be more knowledgeable. Their support right now goes from awkward to funny."
"Based on my experience, the pricing for Tenable Nessus is somewhat higher, but customers still want to pay for it, so it remains acceptable."
"We have had some false positives in the past, which we hope can improve in the future."
"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."
 

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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."
"Qualys TotalCloud is expensive."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
Information not available
"This solution is affordable."
"The product is free."
"The solution has free options."
"The price of the solution is reasonable."
"Tenable Nessus needs to be licensed. We own a license for the security center and that license is charged by the number of IP addresses that you can scan. You're allowed to have as many scanners as you want and there's no license for the number of scanners. We have a bunch of Nessus scanners out there, and as long as we're comfortable with staying under that IP address limit, that's really all we have to be concerned about."
"The price of the solution is reasonable."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
