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.

Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

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

Pros

"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"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."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"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."
"Calico Cloud has had a positive impact on our organization by improving both our Kubernetes security posture and operational efficiency."
"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."
"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."
"Calico Cloud has positively impacted my organization, especially on the security front, as it helped us anticipate security threats."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"Nessus scanner is very effective for internal penetration testing."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The strong security provided by the product in the container environment is its most valuable feature."
 

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."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"There is room for improvement in the support."
"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."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"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"
"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."
"The integration process of Calico Cloud with existing systems has its challenges."
"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."
"Calico Cloud is a very good product with well-defined usage. I would appreciate seeing more improvement on real-time analysis capabilities."
"I think Calico Cloud could be improved by being a bit cheaper."
"The initial setup is highly complex."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"I feel that in certain areas this product has false positives which the company should work on."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"The solution’s pricing could be improved."
