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

"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"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."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"I found the initial setup user-friendly."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"Its excellent graphical interface makes the scanning process simple."
"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 security capabilities that help identify and mitigate risk factors."
"The reporting, dashboarding, and filtering capabilities which provide reports we can present to our senior staff are the most helpful features of Prisma Cloud (Annual Contract)."
"The CWP module, runtime protection, and WAAS API are valuable."
"I would rate Prisma Cloud by Palo Alto Networks ten out of ten."
"We haven't had an issue with the product for over a year."
"Syslog CLIs are the best feature."
"Prisma's identity-based micro-segmentation is better than all its competitors."
"Overall, it gives us fantastic visibility into the cloud environment."
"Prisma was extremely comprehensive. It's easy to drill down to gather more information and keep going. It seemed like you could drill down forever to see what the vulnerability was linked to."
"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 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."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The strong security provided by the product in the container environment is its most valuable feature."
"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."
"Nessus scanner is very effective for internal penetration testing."
 

Cons

"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"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."
"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."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"Their support could be improved."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"Based on my experience, the customization—especially the interface and some of the product identification components—is not as customizable as it could be."
"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."
"Prisma's notifications aren't up to industry standards."
"The UI is good, however, they could improve the experience."
"Prisma Cloud's application security capabilities should be enhanced."
"Other than those two things, we identified a generic bug in the secret key management service on AWS that needs to be fixed."
"The UI could be improved."
"It's not really on par with, or catering to, what other products are looking at in terms of SAST and DAST capabilities."
"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."
"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."
"The initial setup is highly complex."
"The initial setup is highly complex."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
 

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."
"TotalCloud's price is about right where I would expect it to be."
"Qualys TotalCloud is expensive."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"I find the pricing to be expensive."
"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."
"Prisma Cloud is a value-back cloud-managed solution; cloud-native solutions are quite expensive."
"Prisma Cloud Enterprise is a costly solution. You need a license for all the components. At the same time, you have everything under one roof, so I think it's still justified."
"It is an expensive tool. It is not cheap technology. It is a serious investment for any customer. Customers typically buy it together with services. In my experience, customers buying Prisma Cloud are prepared to pay for the implementation and the tool itself."
"Prisma Cloud is affordable."
"The pricing is reasonable."
"Prisma Cloud by Palo Alto Networks has helped the company save some money. Cost-wise, it's okay."
"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 tool's pricing a three out of ten."
"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."
