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

"The most valuable feature is extensibility."

"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."

"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."

"The scalability is good as well. I would rate it ten out of ten."

"We were able to realize its benefits within 24 to 48 hours."

"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."

"I would rate Qualys TotalCloud ten out of ten."

"TotalCloud provides the easiest and the best approach for cloud infrastructure management."

More Qualys TotalCloud pros

"CoreOS Clair can be used by organizations of any size."

"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."

"CoreOS Clair's best feature is detection accuracy."

"CSPM is the most valuable feature for any organization that runs its workloads in the cloud."

"The dynamic workload identity creation, attestation, and assignment is the best feature. In addition, the application dependency map across heterogeneous environments for compliance is a striking feature."

"Its ease of integration is valuable because we need to get the solution out of the door quickly, so speed and ease matter."

"One of the main reasons we like Prisma Cloud so much is that they also provide an API. You can't expect to give someone an account on Prisma Cloud, or on any tool for that matter, and say, "Go find your things and fix them." It doesn't work like that... We pull down the information from the API that Prisma Cloud provides, which is multi-cloud, multi-account—hundreds and hundreds of different types of alerts graded by severity—and then we can clearly identify that these alerts belong to these people, and they're the people who must remediate them."

"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."

"It has helped us build confidence in our security and compliance. Prisma Cloud enables us to implement all these SOC 2 compliances and check the security. It provides visibility and control regardless of how complex our environment is."

"The solution offers very good configuration capabilities."

"Technical support is quite helpful."

Cons

"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."

"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."

"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."

"Customer support with Qualys TotalCloud needs a little improvement with the response times."

"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."

"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."

"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."

"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."

More Qualys TotalCloud cons

"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."

"The cost of Prisma Cloud by Palo Alto Networks is too high. I would also appreciate the addition of NLP to reduce the learning curve and make configuring queries more user-friendly."

"They need to make the settings more flexible to fit our internal policies about data. We didn't want developers to see some data, but we wanted them to have access to the console because it was going to help them... It was a pain to have to set up the access to some languages and some data."

"The alignment of Twistlock Defender agents with image repositories needs improvement."

"The innovation side of the solution could be more efficient and more detailed."

"One definite area for improvement is the auto-remediation or the CWP area. The second one is the RQL language. It is still not very flexible and does not cover a lot of use cases. The RQL language could be dramatically improved to add more options."

"We have discovered that Prisma is not functioning properly with GCP."

"These tools have a set of signatures or rules that will alert you whenever something meets the criteria. In the future, they might include some machine learning or AI feature that allows you to ask questions about the context of the alert, and it will provide you answers based on the data that they have. Most vendors are doing it, and I believe they will do it in the future. The reporting bar could also use AI to add context based on the environment."

"They need to make the settings more flexible to fit our internal policies about data."

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."

"TotalCloud's price is about right where I would expect it to be."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."

"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

"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."

More Qualys TotalCloud pricing and cost advice

"CoreOS Clair is open-source and free of charge."

"The pricing is reasonable."

"The licensing cost is a bit high on the compute side."

"The pricing is competitive; for the most part, the security firms have similar prices."

"If a competitor came along and said, "We'll give you half the price," that doesn't necessarily mean that's the right answer, at all. We wouldn't necessarily entertain it that way. Does it do what we need it to do? Does it work with the things that we want it to work with? That is the important part for us. Pricing wasn't the big consideration it might be in some organizations. We spend millions on public cloud. In that context, it would not make sense to worry about the small price differences that you get between the products."

"Its price is reasonable as compared to other products. The main challenge is explaining the licensing model to customers. It isn't a problem related to Palo Alto. Commonly, people don't understand cloud licensing or security licensing. When they have fixed virtual machines, they know what they are going to be charged, but when it comes to cloud automation, it is hard for them to get clarity in case of high workloads or when they have enabled auto-scaling, etc. It would be helpful if Palo Alto can educate people on their licensing programs."

"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."

"The price for Prisma Cloud is reasonable."

"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
