Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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

"I depend heavily on the reports that I have from this tool."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"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."
"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."
"Qualys TotalCloud provides a single, prioritized view of risk, reducing the workload associated with consolidating multiple sources for risk prioritization."
"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."
"This solution will ensure that we've got a more secure environment, mitigating any sort of bad actors coming in and either destroying or disrupting the environment."
"It gives us a central location to see what the security posture is like for multiple cloud providers."
"I find the CSPM area to be a more valuable and flexible feature."
"The product is quite good for providing multi-clouds or cross-cloud security from a single-pane -of-glass."
"The support is excellent."
"The Prisma Cloud dashboard is powerful, and it gives you at-a-glance compliance security against many standards."
"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."
"It is a good solution. Each team should utilize it. Every good organization is now moving towards or trying to be provider agnostic, so if you are using multiple providers, you should at least give Prisma Cloud a try."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The strong security provided by the product in the container environment is its most valuable feature."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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."
"By using Nessus, we are able to finish testing with assured results, in half the time."
 

Cons

"The support is not up to the mark and seems to be overburdened."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"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."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"Their customer support needs improvement."
"Though Prisma Cloud by Palo Alto Networks provides excellent security, is a pioneer in this space, and knows what it's doing, from a user perspective, it would have been better if it was a little easier to use."
"Prisma could improve the data quality. One challenge is that when an application is deployed on multiple virtual machines, we get an alert for each machine, but the biggest challenge is container flapping. When containers go up and down, we get 100 alerts on one day, but it reports 20 the next day. The numbers keep changing, and the app owners tell us, "You reported a hundred vulnerabilities from my app, and today, you report 20. I haven't made any changes in production, so is your data correct or not?""
"The alignment of Twistlock Defender agents with image repositories needs improvement."
"The information presented in the UI sometimes doesn't look intuitive enough."
"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."
"Prisma is the result of multiple Palo Alto acquisitions, like CWPP, Twistlock, and Aporeto. Though they are part of a single pane of glass, there is no correlation between the solutions."
"Prisma Cloud's dashboards should be customizable. That's very important. Other similar solutions are more elastic so you have the power to create customized dashboards. In Prisma Cloud, you cannot do that."
"They need to make the settings more flexible to fit our internal policies about data."
"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."
"The initial setup is highly complex."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
"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."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"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."
"Qualys TotalCloud is expensive."
"Prisma Cloud by Palo Alto Networks carries a higher cost, but its enhanced security measures justify the expense."
"Prisma Cloud is more expensive than Check Point CloudGuard."
"The cost was not on the higher side. Overall, the cost gets recovered with its implementation."
"The product is very expensive, but the cost is a necessary evil; I don't know how we could have any kind of cloud presence without this type of monitoring. The pricing is calculated by module and resource usage. Ultimately, it saves us money in the amount of time we would spend uncovering what it uncovers, and we might not make the required discoveries without it anyway. Prisma offers incredible value, though I wish it were cheaper."
"The pricing is good. They gave us some good discounts right at the end of the year based on the value that it brings, visibility, and the ability to build in cloud, compliance, and security within one dashboard."
"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."
"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."
"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 solution's pricing is neither cheap nor very expensive."
"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 product does not operate on a pay-per-license model."
"I rate the tool's pricing a three out of ten."
"I rate the product’s pricing a six out of ten."
