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.

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.

Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers
Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.

Tenable Nessus is a vulnerability assessment solution that is both easy to deploy and easy to manage. The design of the program is such that if a company should desire to handle the installation themselves, they would be able to do so. The updates that the program requires to keep up-to-date take up a large portion of the setup time. Tenable Nessus can be deployed in under an hour. The speed of an organization’s internet can impact how quickly the deployment will go. Furthermore, once it has been set up, only a small management team is necessary for maintenance. Tenable Nessus is an incredibly important program that provides businesses and organizations with robust protection. This ease of deployment and management gives it an edge over the competition. Tenable.io Vulnerability Management is basically comparable to Tenable Nessus in regards to setup and management. It is relatively straightforward to set up. A single person could deploy it in a non-business setting in a matter of hours. The setup can be handled without requiring a business to rely on the help of outside consultants. As with Tenable Nessus, a small team of two or three people is all that is necessary to manage the solution. Organizations can save a great deal of time and resources by choosing to utilize this solution. Tenable Nessus is a solution with good scalability. This can be accomplished with relative ease. However, the load that it can handle makes it a poor fit for larger organizations. At a certain point, the farther up you scale it, the more the solution quality diminishes. Tenable.io Vulnerability Management is able to offer a much higher level of scalability. It is typically used without trouble by organizations with many thousands of users. As with Tenable Nessus, the process is relatively simple. Conclusion: The actual difference in time and ease as far as deploying Tenable Nessus versus Tenable.io Vulnerability Management is negligible and cannot truly set one apart from the other. Ease of management is another area where these two solutions are very similar. A major difference between them is their scalability. While both can be scaled relatively easily, Tenable.io Vulnerability Management is able to handle a higher level of scalability, with the diminishment of quality being a far lesser concern than is the case with Tenable Nessus.

Both, but I prefer Nessus Pro (costs and you can define out-of-band your better presentation/xLAP platform). Tenable.io has its facilities and extra plugins/views/analytics, but nothing that can't be externally performed by another ETL/presentation tool (for a fraction of cost, sometimes using free toolings like Pentaho, OpenRefine, OBIEE and others).
