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.

Runtime threat detection has improved and security teams prioritize real Kubernetes risks
The best feature Sysdig Secure offers is threat detection. The threat detection feature on Sysdig Secure stands out compared to other solutions I have seen or used because Sysdig sees the actual behavior inside the container or kernel and correlates it with Kubernetes infrastructure, which makes detection both earlier and more precise in a cloud-native environment. Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads.

Quotes from Members

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

Pros

"I would rate Qualys TotalCloud ten out of ten."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"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 definitely recommend Qualys TotalCloud to other customers."
"The best part I like is the on-demand scans."
"I would definitely recommend it because it is easy to handle any cloud resources."
"Once it is set up, Qualys has proved to be one of our greatest assets."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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."
"The tool has the capability to conduct scans initially. It can perform scans on your virtual machines, physical machines, containers, and container images. A standout feature is its ability to scan offline container images stored in your container registry. Additionally, it can scan runtime images in your cluster or on your host machine. This allows for the detection of vulnerabilities in running containers, including loaded libraries. Notably, the tool can identify which library vulnerabilities are already present in your system. An added advantage is its capacity to take action beyond threat detection. It has the ability to block access and respond to encountered threats."
"I see Sysdig as the most comprehensive solution in comparison to its competitors."
"From a container-based standpoint, it offers excellent scalability to its users...I would tell those planning to use the solution that, from a container standpoint, it's excellent."
"The most valuable feature is the level of support that we get. Our solutions or customer success representative is very valuable. I see them as an extension of our security team."
"In terms of measurable outcomes, I have seen a reduction in vulnerabilities, as Sysdig Secure can tell us how many vulnerabilities are present on a day-to-day report basis, which has improved our efficiency by more than 50% and helps us stay compliant with necessary regulations."
"We appreciate this feature, especially when combined with CD monitoring. The implementation of requested features has been remarkable, such as scanning for compliance in CRM processes for the US government. We heavily rely on this feature to assess compliance with federal requirements."
"The proactiveness of the support has been fantastic. Every time we mention something in a meeting that we're trying to do, he proactively takes that as an investigation topic and looks into it. He'll provide the solution even though we might not have asked him to investigate it."
"The log monitor is the most valuable feature."
 

Cons

"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."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"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 my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"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."
"One thing that could be improved is the user experience and navigation."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"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 solution needs to improve overall from a CSPM standpoint since they can't compete with Wiz or Orca."
"Sysdig Secure needs to scale more for complete cloud-native coverage."
"Sysdig's biggest weakness is dashboarding and reporting. You have access to the data and can get everything you need, but we need the ability to summarize the information quickly in a format that senior leaders can understand. We report to the executive level and global board. I need to roll all that in-depth information into a quick summary, and their maturity level isn't there. I'm seeing that on the future road map, but it isn't there now."
"The dashboard could be more simple and show the more important issues that are detected first. We'd like to be able to set it up so more important issues show up more prominently in the dashboard."
"Sysdig Secure works well for us, but there are a few areas for improvement, such as the alerting and notification system being more flexible for complex workflows, and some dashboard and reporting features could be more customizable to match specific team needs."
"Reporting can definitely be better. Live dashboards should be configurable for a longer period of time rather than 30 days. Being able to go back in time to compare six months ago to today would be valuable."
"Perhaps, it could support more custom implementations, as our company utilizes custom implementations rather than standard ones. Configuring it requires a deep understanding and adjustment to our specific needs, which took some time. Other than that, I'm unsure about potential improvements. We were considering the possibility of compartmentalizing their tools. Currently, in Sysdig Secure, they bundle multiple features, and we are unable to use them individually. For instance, if we only need compliance scanning, we have to deploy the entire secure package. This is because of the way their agent functions, but I can't delve into more details."
"There was a security concern related to a specific feature. While the feature itself was promising, it posed a challenge. The situation revolved around code scanning. If your source code is hosted within your own premises, say on Bitbucket, you naturally wouldn't want your code to be accessible to external parties beyond your company. Keeping your code base private is a standard practice. However, in the case of code scanning using Sysdig Secure, they copy your code to their SaaS platform. This posed an issue for us. When we inquired about this, their response acknowledged the concern. In an upcoming release, they plan to enable code scanning within your on-premises environment through the assistance of an agent. This change is already in progress. While this tool stands out compared to existing solutions in the market, it's important to note that there are still some limitations to consider. Another drawback we encountered relates to our expertise with Kubernetes. The tool can monitor Kubernetes audit logs, triggering alerts and notifications. However, it falls short in terms of taking direct action based on these alerts. There are different methods of event capture, including through system labels and system calls, as well as via Kubernetes audit events. Notably, at the system level, Sysdig Secure can both detect and respond to events, allowing actions like blocking and warning. This proactive approach is effective at the system call level. However, when it comes to monitoring Kubernetes audit events, Sysdig Secure can only notify without being able to execute any further actions. It can't block access or containers. The vendor likened their role to that of a monitoring camera, observing events and sending notifications without the capacity to intervene. This limitation applies to Kubernetes audit events. Given that everything operates within our system, there is a workaround available: configuring system-level policies to block containers as necessary."
 

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."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"TotalCloud's price is about right where I would expect it to be."
"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."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"CoreOS Clair is open-source and free of charge."
"I am always going to say that it could be a little bit cheaper. I do feel that it is a little bit on the expensive side."
"Sysdig is competitive. The quality matches the pricing. Obviously, everyone wants things to be cheaper, but if you're realistic, you acknowledge that quality service comes with a price. Sysdig is the gold standard for Kubernetes, and I wouldn't choose anything else. We live in Kubernetes. Everything is containerized, so that means a lot to us, and we're willing to make an investment."
"In comparison to other cloud solutions, it's reasonably priced. However, when compared to in-house built open-source projects, it might be considered somewhat costly. The cost depends on whether someone sees the support provided by Sysdig as an advantage or if it's deemed unnecessary. Personally, I find the support to be excellent and consider it a good value."
"The solution's pricing depends on the agents...In short, the price depends on the environment of its user."
"It is quite costly compared to other tools."
