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.

Image scanning has supported consistent security practices during cloud deployment
On a scale of ten, we would say people are happy with Prisma Cloud by Palo Alto Networks for the part we use. People are okay with it. We probably would give an eight. We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view. We could have deployed the runtime monitoring with Prisma Cloud by Palo Alto Networks, but within our organization at our company, it was very difficult to find who would be the owner for the alerts. People have other tools and in the end, we don't use the full capabilities of a product that we pay for. It's partially related to the difficulty to integrate Prisma Cloud by Palo Alto Networks runtime in our company's support process. We don't use the real-time monitoring part of Prisma Cloud by Palo Alto Networks. We don't know about the automated remediation feature of Prisma Cloud by Palo Alto Networks.

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

"My experience with using TruRisk to mitigate noise from raw CVEs has been extremely effective."
"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"Multi-cloud visibility saves time and makes things easier, as we can also have comparability to see what configuration differences have been made from cloud to cloud."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"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."
"I would rate Qualys TotalCloud ten out of ten."
"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."
"Before implementing Prisma Cloud, we didn't have any visibility into workspaces like Kubernetes and the underlying network of containers, but now we have a better understanding of the resources interacting with Kubernetes and can identify vulnerabilities across the organization."
"The UI is very good. We get all the things within a single UI."
"Syslog CLIs are the best feature."
"It has a feature for customized security policy. I implement it in banking, health insurance, and other sectors, and every organization has its own customized policies and procedures. In Prisma Cloud, you can customize policies, and based on that, you can do monitoring."
"The client wasn't using all of the features, but the one that stood out was infrastructure-as-code (IaC). I built IaC use cases and was trying to get them to use it. I also liked cloud workload protection. I worked with the vulnerability management team to develop a process. It's a manual process, so it can be challenging to remediate many image or container issues. It was nice that we could build out a reporting process and download the reports. The reports are solid."
"Prisma scans things and shows all the vulnerabilities and packages that are vulnerable, and which layers, by default, have vulnerabilities. So developers can easily go into the package or a particular layer and make changes to their code. It's very transparent."
"It has helped us understand the dynamic topology of our containers, and manage security through the application of policies that our pipelines apply straight from Git."
"Prisma Cloud provides the visibility and control that we need, regardless of how complex or distributed our cloud environments become, which is very nice."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The strong security provided by the product in the container environment is its most valuable feature."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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."
 

Cons

"Their customer support needs improvement."
"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."
"It is already perfect, but they can bring some newer dashboards and customization options for the dashboard. It would be great to be able to include on-prem assets on the dashboard."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"There is room for improvement in the support."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"The integration of the Compute function into the cloud monitoring function—because those are two different tools that are being combined together—could use some more work. It still feels a little bit disjointed."
"A couple of exporting functionalities should be more user-friendly because if I want to export something, I can get a lot of data visible to that particular CSV."
"The alignment of Twistlock Defender agents with image repositories needs improvement. These deployed agents have no way of differentiating between on-premise and cloud-based image repositories. If I deploy a Defender agent to secure an on-premise Kubernetes cluster, that agent also tries to scan my ECR image repositories on AWS. So, we have limited options for aligning those Defenders with the repositories that we want them to scan. It is scanning everything rather than giving us the ability to be real granular in choosing which agents can scan which repositories."
"I don't think their SaaS offering is adoptable by large enterprises like ours, in every case."
"Sometimes, when you assign subnets to regions, the IP address will jump from one location to another because it will automatically change substantially. Then, we need to add those IP subnets to our firewall for existing access. The need to update those subnets potentially causes maintenance or access issues. So far, we can only provide bigger customers with six subnets, and a small company may not be able to access those services."
"The access controls for our bank roles were not granular enough. We needed specific people to do particular actions, and we often had to give some people way too much access for them to be able to do what they needed in Prisma. They couldn't do their jobs if they didn't have that level of access, so other people had to do that part for them. It would help to have more granular role-based access controls."
"We are encountering issues with the new permissions required for AWS integration with Prisma."
"Getting new guys trained on using the solution requires some thought. If someone is already trained on Palo Alto then he's able to adapt quickly. But, if someone is coming from another platform such as Fortinet, or maybe he's from the system side, that is where we need some help. We need to find out if there is an online track or training that they can go to."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
"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."
"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."
"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."
"The initial setup is highly complex."
 

Pricing and Cost Advice

"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"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 cost-effective licensing flexibility."
"Qualys TotalCloud is expensive."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Prisma Cloud is a value-back cloud-managed solution; cloud-native solutions are quite expensive."
"The pricing and the licensing are both very fair... The biggest advice I would give in terms of costs would be to try to understand what the growth is going to look like. That's really been our biggest struggle, that we don't have an idea of what our future growth is going to be on the platform. We go from X number of licenses to Y number of licenses without a plan on how we're going to get from A to B, and a lot of that comes as a bit of a surprise. It can make budgeting a real challenge for it."
"If you pay for three years of Palo Alto, it's better. If you're planning on doing this, it's obviously not going to be for one year, so it's better if you go with a three-year license... The only challenge we have is with the public cloud vendor pricing. The biggest lesson I have learned is around the issues related to pricing for public cloud. So when you are doing your segmentation and design, it is extremely important that you work with someone who knows and understands what kinds of needs you will have in the future and how what you are doing will affect you in terms of costs."
"The cost was not on the higher side. Overall, the cost gets recovered with its implementation."
"The pricing is reasonable."
"The pricing structure is easy to understand. Depending on the use case the pricing of the solution can be different. There are not any additional costs to the standard living fees."
"Regarding Prisma Cloud's pricing, we started small, and then we just kept on growing."
"The pricing is competitive; for the most part, the security firms have similar prices."
"The product does not operate on a pay-per-license model."
"I rate the product’s pricing a six out of ten."
"The solution's pricing is neither cheap nor very expensive."
"I rate the tool's pricing a three out of ten."
"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
