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.

Offers easy management and container connection with HTTPS, but the support needs to improve

I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

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.

More Sysdig Secure pros

Cons

"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."

"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."

"Their customer support needs improvement."

"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."

"There is a lack of data segregation according to criticality or inventory."

"I didn't give it a ten because I would like to see simpler configuration, more customizable dashboards, and better automation and integration options."

"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."

"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."

More Qualys TotalCloud cons

"The testing process could be improved."

"Red Hat is somewhat expensive."

"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."

"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."

"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."

"The support and specifications need to be up to date for the cluster technologies"

"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."

"The solution's price could be better."

More Red Hat Advanced Cluster Security for Kubernetes cons

"I give it an eight because of the bugs, specifically the fix version bug where sometimes there is no fix version shown, and I wish Sysdig Secure would create a customizable UI that orders features by importance to enhance user experience."

"The solution needs to improve overall from a CSPM standpoint since they can't compete with Wiz or Orca."

"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."

"Sysdig Secure needs to scale more for complete cloud-native coverage."

"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."

"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."

"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."

"Banks and financial institutions cannot use Sysdig Secure because it doesn't sell SaaS-hosted versions for under two hundred working nodes."

More Sysdig Secure cons

Pricing and Cost Advice

"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 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."

"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."

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

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

"Qualys TotalCloud offers cost-effective licensing flexibility."

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

More Qualys TotalCloud pricing and cost advice

"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."

"We purchase a yearly basis license for the solution."

"It's a costly solution"

"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."

"The pricing model is moderate, meaning it is not very expensive."

"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."

"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."

"It is quite costly compared to other tools."

"The solution's pricing depends on the agents...In short, the price depends on the environment of its user."

"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."
