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.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Image scanning has supported consistent security practices during cloud deployment
On a scale of ten, we would say people are happy with Prisma Cloud by Palo Alto Networks for the part we use. People are okay with it. We probably would give an eight. We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view. We could have deployed the runtime monitoring with Prisma Cloud by Palo Alto Networks, but within our organization at our company, it was very difficult to find who would be the owner for the alerts. People have other tools and in the end, we don't use the full capabilities of a product that we pay for. It's partially related to the difficulty to integrate Prisma Cloud by Palo Alto Networks runtime in our company's support process. We don't use the real-time monitoring part of Prisma Cloud by Palo Alto Networks. We don't know about the automated remediation feature of Prisma Cloud by Palo Alto Networks.

Quotes from Members

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

Pros

"Its dashboards are brilliant. It provides in-depth insights."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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."
"I would rate Qualys TotalCloud ten out of ten."
"Qualys TotalCloud has great accuracy and reliability, as it is a very complete program with tools that help experts understand the vulnerabilities of today."
"Qualys TotalCloud has positively impacted our organization by helping us save time and manage all assets and remediation, allowing us to achieve quarterly and half-yearly goals."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"CoreOS Clair can be used by organizations of any size."
"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"We haven't had an issue with the product for over a year."
"It gives us a central location to see what the security posture is like for multiple cloud providers."
"The product is quite good for providing multi-clouds or cross-cloud security from a single-pane -of-glass."
"Prisma Cloud has good integrations, provides the visibility and control we need, is far more reasonable for the customers cost-wise, and is a very good preventative tool for helping us identify misconfigurations, reduce false positives, and focus on the real risks in our cloud environment."
"Most of the customers we are tackling have different tools and solutions, like Qualys, Nessus, and vulnerability management assessment solutions. There are plugins for them, and we can integrate Prisma Cloud with them. We can enrich our telemetry with their data and use the predefined correlation rules in Prisma Cloud. That means we have that work done in seconds."
"Engineering is thinking it's easy to integrate because we use many Red Hat products."
"The CWP module, runtime protection, and WAAS API are valuable."
"It is a good solution. Each team should utilize it. Every good organization is now moving towards or trying to be provider agnostic, so if you are using multiple providers, you should at least give Prisma Cloud a try."
 

Cons

"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"The improvement needed in Qualys TotalCloud is mainly in the artificial intelligence automation agents, where we can customize and create what meets our needs, not necessarily having to use those provided in the tool."
"The cost of Qualys TotalCloud is high and could be more competitive."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"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."
"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"
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"There is a lack of data segregation according to criticality or inventory."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"In terms of securing cloud-native development at build time, a lot of improvement is needed. Currently, it's more a runtime solution than a build-time solution. For runtime, I would rate it at seven out of 10, but for build-time there is a lot of work to be done."
"We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view."
"If I were to improve Prisma Cloud by Palo Alto Networks, I would enhance the integration with other vendors."
"The automation capabilities are growing each day, but the problem is that the updates are not that frequent. There are some services on Amazon that have come out with updates, and Azure is also getting up to date. But Prisma takes some time to follow. There's a time gap that Prisma inherits from these clouds. I understand why it takes some time, but that time should be reduced."
"Support is an area that needs improvement."
"We would like it to have more features from the risk and compliance perspectives."
"Prisma is the result of multiple Palo Alto acquisitions, like CWPP, Twistlock, and Aporeto. Though they are part of a single pane of glass, there is no correlation between the solutions."
"I don't think their SaaS offering is adoptable by large enterprises like ours, in every case."
 

Pricing and Cost Advice

"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 offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"The cost is high, but it meets our organizational needs."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
