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

"We were able to realize its benefits within 24 to 48 hours."
"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."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"I would definitely recommend Qualys TotalCloud to other users."
"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."
"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."
"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."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"The Prisma Cloud dashboard is powerful, and it gives you at-a-glance compliance security against many standards."
"Configuration monitoring and alerting is the most valuable feature; it happens at the cloud's speed, allowing our development team to respond quickly. If a configuration goes against our security best practices, we're alerted promptly and can act to resolve the issue. As cloud security staff, we're not staring at the cloud all the time, and we want to let the developers do their jobs so that our company is protected and work is proceeding within our security controls."
"It has helped us build confidence in our security and compliance. Prisma Cloud enables us to implement all these SOC 2 compliances and check the security. It provides visibility and control regardless of how complex our environment is."
"It gave us visibility into and control over complex cloud environments, which helped us feel better about our security and secure the environment with the clinical data."
"The most valuable features are the alerts and auto-remediation because it allows us a lot of flexibility to customize and do things the Palo Alto team never intended. We faced some challenges with certificates because we also have next-gen firewalls. We would like to equip all the traffic because there have been many cases in which the developers have done things by mistake. Deploying certificates on virtual machines can be complex in a development environment, but we managed to do that with Prisma Cloud."
"Prisma Cloud's inventory reporting is pretty good."
"It also provides us with a single tool to manage our entire cloud architecture. In fact, we are using a multi-account strategy with our AWS organization. We use Prisma as a single source of truth to identify high- or medium-severity threats inside our organization."
"We found it to be easy and flexible. We could easily configure it for our needs, and we could spread the Prisma Cloud platform to 16 countries without encountering any kind of problem."
"Nessus scanner is very effective for internal penetration testing."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
 

Cons

"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"There is a lack of data segregation according to criticality or inventory."
"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."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"Their support could be improved."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"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."
"There should be some kind of automation, AI incorporation, and bot system. All these would add value."
"Having auto Defender upgrades so that we do not have to upgrade Defender manually would be helpful."
"One major observation is that it is not possible to implement Prisma Cloud on-premises. This is the limitation. Prisma Cloud itself is on a cloud. It is sitting on AWS and Google Cloud. It is a SaaS solution, but some of my clients have a local regulatory requirement, and they want to install it locally on their premises. That capability is not there, but government entities and ministries want to have Prisma Cloud installed locally."
"The UX part of Prisma's user interface could be simplified and the metrics tool should be highlighted more."
"These tools have a set of signatures or rules that will alert you whenever something meets the criteria. In the future, they might include some machine learning or AI feature that allows you to ask questions about the context of the alert, and it will provide you answers based on the data that they have. Most vendors are doing it, and I believe they will do it in the future. The reporting bar could also use AI to add context based on the environment."
"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."
"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."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"The solution’s pricing could be improved."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
 

Pricing and Cost Advice

"TotalCloud's price is about right where I would expect it to be."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"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."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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 good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"The cost is high, but it meets our organizational needs."
"You can expect a premium price because it is a premium quality product by a leading supplier."
"The price for Prisma Cloud is reasonable."
"The Prisma Cloud pricing is good."
"From my exposure so far, they have been really flexible on whatever your current state is, with a view to what the future state might be. There's no hard sell. They "get" the journey that you're on, and they're trying to help you embrace cloud security, governance, and compliance as you go."
"The pricing is competitive. From what I have seen in the past, it is on par with the others."
"Its licensing cost depends on the type of license such as the business license or the enterprise license. The enterprise license is costlier than the business license, but we get more visibility and more modules. If you have a multi-cloud environment and subscribe to each cloud's native CSPM tool, it is costly. If you are using a single tool like Prisma Cloud, with a single license, you can monitor all environments, such as Google Cloud, Azure, AWS, and Oracle Cloud. The cost of Prisma Cloud is less than the cost of subscribing to the CSPM tool of each cloud provider. This is where Prisma Cloud can save costs."
"Prisma Cloud is affordable."
"Almost all the CSPM tools are pretty expensive."
"I rate the tool's pricing a three out of ten."
"The product does not operate on a pay-per-license model."
"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."
"I rate the product’s pricing a six out of ten."
