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.

Endpoint monitoring has strengthened incident response and provides rapid isolation and forensics
Tanium provides an endpoint which is isolated from the network and environment. We can easily search its logs and history and connect remotely directly to that particular device which has been isolated from the network. We can search for the history and logs, including audit logs and event logs. The complete activity of the user or owner of the device is visible to us. We can see the artifacts of particular USB transfers internally for official use. We can not only connect remotely but also see the device status and how many failures have occurred within the network so far. We can see the IP address, how many times it has changed its IP address, and how many times it was connected to VPN or external VPN or internal VPN and what has been searched while on VPN. We can block the IOCs or IP addresses as well. We can block domains, hashes, SHA values, SHA-256, SHA-1, SHA-5 and MD5. Although I am not completely involved in the automation team, we do have that team and I have worked in some CERT recently. Tanium is more useful while we are in the CERT because most of the times when we are on high alert, Tanium does play a main role for that particular incident or any high case. Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint. It is mandatory to give any RDP connection and the tool should be present in the particular device. It is completely mandatory and it is in the policy as well.

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

"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"Qualys TotalCloud is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other 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's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"I depend heavily on the reports that I have from this tool."
"The scalability is good as well. I would rate it ten out of ten."
"Tanium has made the process of detecting threats more proactive with its detection. So, the process is easier and more efficient."
"I find the inventory and compliance features of Tanium to be the most impressive."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium is a very good product and I would rate it eight or nine out of ten."
"I like the tool's incident response and security patching."
"The interrogation piece was the most valuable feature because it was very detailed."
"I like the fact that you can create patching campaigns depending on the area of your network that you want to address first. I like the ability it has to make several campaigns that work in parallel."
"The security features are very valuable."
"Nessus has greatly improved the security of our clients' networks."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"Tenable Nessus is an absolutely stable and fantastic product."
"The solution can conduct a full vulnerability assessment and also suggest mitigation of vulnerabilities and has a lot of other features."
"Vulnerability assessment is the most valuable feature in Tenable Nessus, as it provides brief details regarding the vulnerability issues we have in our network."
"I have chosen Nessus because it's very simple to use and install."
"It is a very easy tool to use."
"Tenable Nessus has helped us with better visibility of the current security posture of our infrastructure and helped us be proactive about remediating those findings."
 

Cons

"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"The cost of Qualys TotalCloud is high and could be more competitive."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"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."
"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"The solution needs to improve the reporting and tracking capabilities."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"When working with Tanium, there are some older devices that haven't been patched for a long time, and certain patches are not included in Tanium. I have to search outside to download patches, create bundles, and then perform the task."
"Our biggest issue with the solution is its lack of mobility."
"We had some issues with the solution's OS upgrade."
"The most painful thing is the interface. It's a bit unclear sometimes."
"Tanium’s scalability could be improved."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
"Online learning could be a bit better."
"Tenable Nessus is very costly compared to OpenVAS and sits on the higher side."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"One area that has room for improvement is the reporting. I'm preparing reports for Windows and Linux machines, etc. Currently, I'm collecting three or four reports and turning them into one report. I don't know if it is possible to combine all of them in one report, but that would be helpful."
"To be honest, I haven't used it much to tell you that these are the things that should be improved. But I believe the UI should be enhanced somewhat. For example, there are two ways to find a report, and people are frequently confused as to which is the correct method for locating a full report. Sometimes they go in the opposite direction, so this is an area that may be improved."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"The price could be more reasonable. I used the free Nessus version in my lab with which you can only scan 16 IP addresses."
"Nessus' reporting could be more user-friendly."

"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"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."
"This solution is affordable."
