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.

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

"Qualys TotalCloud has positively impacted our organization by helping us save time and manage all assets and remediation, allowing us to achieve quarterly and half-yearly goals."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."
"I highly recommend Qualys TotalCloud to other users."
"I would definitely recommend it because it is easy to handle any cloud resources."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"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."
"Prisma Cloud is a single tool that we can use to protect all of our cloud resources without having to manage and reconcile several security and compliance reports."
"The Cloud Workload Protection module is a very strong solution. I like the Cloud Workload Protection part. It is something I have not used for the banking client, but I had a chance to try it out for roughly a month on actual deployment of another customer. That part was really robust. Cloud Workload Protection would be the main feature that I enjoy the most."
"I like the scanning features provided by Prisma Cloud, including the image scan and source scan."
"It helps to identify the misconfigurations by monitoring regularly which helps to secure the organization's cloud environment."
"The most valuable features are vulnerability monitoring, serverless access, container runtime features, and Defender."
"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."
"Its ease of integration is valuable because we need to get the solution out of the door quickly, so speed and ease matter."
"The Twistlock vulnerability scanning tool is its most valuable feature. It provides us insight into security vulnerabilities, running inside both on-premise and public cloud-based container platforms. It is filling a gap that we have with traditional vulnerability scanning tools, where we don't have the ability to scan inside containers."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"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."
"Nessus scanner is very effective for internal penetration testing."
"The strong security provided by the product in the container environment is its most valuable feature."
"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."
"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."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"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."
"The cost of Qualys TotalCloud is high and could be more competitive."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"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."
"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"There is a lack of data segregation according to criticality or inventory."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"The pricing for the solution needs improvement."
"The remediation part could be better."
"This solution is more AWS and Azure-centric. It needs to be more specific on the GCP side, which they are working on."
"This could be one input that its pricing could be adjusted with respect to other competitors regarding any new features that could be added or improvements to be made in Prisma Cloud (Annual Contract)."
"Prisma Cloud's enterprise reporting needs significant improvement."
"In terms of improvement, there are some small things like hardening and making sure the Linux resources are deployed well but that's more at an operational level."
"Having auto Defender upgrades so that we do not have to upgrade Defender manually would be helpful."
"Some of the usability within the Compute functionality needs improvement. I think when Palo Alto added on the Twistlock functionality, they added a Compute tab on the left side of the navigation. Some of the navigation is just a little dense. There is a lot of navigation where there is a tab and dropdowns. So, just improving some of the navigation where there is just a very dense amount of buttons and drop-down menus, that is probably the only thing, which comes from having a lot of features. Because there are a lot of buttons, just navigating around the platform can be a little challenging for new users."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
"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 support is tricky to reach, so we would like better-oriented technical support enabled."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The solution’s pricing could be improved."
 

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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 good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"Prisma Cloud is a high-end enterprise solution, making it quite expensive."
"Prisma Cloud by Palo Alto Networks carries a higher cost, but its enhanced security measures justify the expense."
"Our licensing fees are $18,000 USD per year."
"This solution is good for a company with at least 400 people that must be connected remotely. For smaller companies, it can be too 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 a competitor came along and said, "We'll give you half the price," that doesn't necessarily mean that's the right answer, at all. We wouldn't necessarily entertain it that way. Does it do what we need it to do? Does it work with the things that we want it to work with? That is the important part for us. Pricing wasn't the big consideration it might be in some organizations. We spend millions on public cloud. In that context, it would not make sense to worry about the small price differences that you get between the products."
"Prisma Cloud is cost-efficient, but the credits are on the higher end."
"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."
"The solution's pricing is neither cheap nor very expensive."
"I rate the tool's pricing a three out of ten."
"I rate the product’s pricing a six out of ten."
"The product does not operate on a pay-per-license model."
