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.

Security posture has become visible and container risks are managed proactively
Regarding improvements for Calico Cloud, there is a need to build agentic security systems. I believe Calico Cloud is progressing towards this, and I believe they can enhance their teaching methods to facilitate adoption. Documentation needs continuous improvement. It is good and easy to read, but it can get better. Having a searchable summary feature, such as a chatbot, could help users quickly resolve issues without having to read extensive documentation. At the moment, I do not believe there are more improvements needed, but as mentioned earlier, there should be a focus on better documentation, possibly by embedding chatbot features that could respond to user prompts effectively.

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.

Quotes from Members

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

Pros

"I found the initial setup user-friendly."
"We were able to realize its benefits within 24 to 48 hours."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"Qualys TotalCloud is overall the best tool available in the market for scanning purposes."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"Calico Cloud has positively impacted my organization by improving the security of deployed applications while having greater control and visibility over communication between the different microservices."
"Calico Cloud has positively impacted my organization, especially on the security front, as it helped us anticipate security threats."
"Calico Cloud has had a positive impact on our organization by improving both our Kubernetes security posture and operational efficiency."
"The number one standout feature is the multi-cloud hybrid workload support, as the fact that Calico Cloud is not strictly bound to Kubernetes pods but can also utilize bare metal or virtual machines means it offers a unified control plane and allows for a single security policy to be applied and for traffic flow to be observed between VM-based databases and containerized applications running in Kubernetes, which is amazing for increasingly popular hybrid workloads."
"The impact of Calico Cloud is that we were able to achieve a more secure understanding of our security posture, access our containers knowing full well that all policies set were followed through, and see visually how everything was interconnected, which has impacted our business positively."
"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 can be used by organizations of any size."
"CoreOS Clair's best feature is detection accuracy."
 

Cons

"The response part of the Cloud Detection and Response (CDR) module can be improved."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"There is room for improvement in the support."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"There is a lack of data segregation according to criticality or inventory."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"Another issue is the resource footprint because Calico Cloud is an all-inclusive networking solution with many daemons running inside the cluster, putting a noticeable load on the Kubernetes API server in large clusters."
"They may not have all the features that their competitor Cilium has, and they are doing a portion of what Cilium does and a portion of what Istio does."
"I think Calico Cloud could be improved by being a bit cheaper."
"Calico Cloud is a very good product with well-defined usage. I would appreciate seeing more improvement on real-time analysis capabilities."
"The integration process of Calico Cloud with existing systems has its challenges."
"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."
 

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"TotalCloud's price is about right where I would expect it to be."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is expensive."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"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."
