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.

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.

SecOps program for us, as a smaller company, is amazing; they know what to look for
They could give a few more insights into security groups and recommendations on how to be more effective. That's getting more into the AWS environment, specifically. I'm not sure if that's Threat Stack's plan or not, but I would like them to help us be efficient about how we're setting up security groups. They could recommend separation of VPCs and the like - really dig into our architecture. I haven't seen a whole lot of that and I think that's something that, right off the bat, could have made us smarter. Even as part of the SecOps Program, that could be helpful; a quick analysis. They're analyzing our whole infrastructure and saying, "You have one VPC and that doesn't make a lot of sense, that should be multiple VPCs and here's why." The architecture of the servers in whatever cloud-hosting provider you're on could be helpful. Other than that, they should continue to expand on their notifications and on what's a vulnerability. They do a great job of that and we want them to continue to do that. It would be cool, since the agent is already deployed and they know about the server, they know the IP address, and they know what vulnerability is there, for them to test the vulnerability and see if they can actually exploit it. Or, once we patch it, they could double-check that it can't be. I don't know how hard that would be to build. Thinking on it off the top off my head, it could be a little challenging but it could also be highly interesting. It would also be great if we could test a couple of other features like hammering a server with 100 login attempts and see what happens. Real test scenarios could be really helpful. That is probably more something close to what they do with the SOC 2 audit or the report. But more visualization of that, being able to test things out on our infrastructure to make sure we can or can't hit this box could be interesting.

Quotes from Members

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

Pros

"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"The scalability is good as well. I would rate it ten out of ten."
"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."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"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 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."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"The strong security provided by the product in the container environment is its most valuable feature."
"Nessus scanner is very effective for internal penetration testing."
"An important feature of this solution is monitoring. Specifically, container monitoring."
"We find the licensing and pricing very easy to understand and a good value for the services provided."
"The capacity to respond to evidence requests from the SOX auditors has significantly improved because of this tool."
"The SecOps program is absolutely amazing when you do not have a dedicated resource for security."
"Every other security tool we've looked is good at containers, or at Kubernetes, is good at AWS, or at instance monitoring. But nobody is good at tying all of those things together, and that's really where Threat Stack shines."
"It has been quite helpful to have the daily alerts coming to my email, as well as the Sev 1 Alerts... We just went through a SOX audit and those were pivotal."
"The number-one feature is the monitoring of interactive sessions on our Linux machines. We run an immutable environment, so that nothing is allowed to be changed in production... We're constantly monitoring to make sure that no one is violating that. Threat Stack is what allows us to do that."
"The solution has a lot of different features that are quite useful."
 

Cons

"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"One thing that could be improved is the user experience and navigation."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"The price is very expensive, actually."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"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."
"In terms of improvement, remediation still belongs to the cloud team, which is one of the issues we faced with Qualys TotalCloud."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"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."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"It's too expensive, but I'm always going to say that. It is very expensive compared to some other products."
"The reports aren't very good. We've automated the report generation via the API and replaced almost all the reports that they generate for us using API calls instead."
"The API - which has grown quite a bit, so we're still learning it and I can't say whether it still needs improvement - was an area that had been needing it."
"They could give a few more insights into security groups and recommendations on how to be more effective."
"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."
"They could give a few more insights into security groups and recommendations on how to be more effective. That's getting more into the AWS environment, specifically. I'm not sure if that's Threat Stack's plan or not, but I would like them to help us be efficient about how we're setting up security groups. They could recommend separation of VPCs and the like - really dig into our architecture. I haven't seen a whole lot of that and I think that's something that, right off the bat, could have made us smarter."
"The user interface can be a little bit clunky at times... There's a lot of information that needs to be waded through, and the UI just isn't great."
"The solution’s ability to consume alerts and data in third-party tools (via APIs and export into S3 buckets) is moderate. They have some work to do in that area... The API does not mimic the features of the UI as far as reporting and pulling data out go. There's a big discrepancy there."
 

Pricing and Cost Advice

"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."
