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

"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"Qualys TotalCloud has improved our security posture."
"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 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."
"In my opinion, this is the best tool."
"I highly recommend Qualys TotalCloud to other users."
"Its dashboards are brilliant. It provides in-depth insights."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"The product is quite good for providing multi-clouds or cross-cloud security from a single-pane -of-glass."
"The first aspect that is important is the fact that Prisma Cloud is cloud-agnostic. It's actually available for the five top cloud providers: AWS, GCP, Azure, Oracle, and Alibaba Cloud. The second aspect is the fact that we can write our own rules to try to detect misconfigurations in those environments."
"The runtime mechanism on the solution is very useful, and it has very good network mapping between containers, so if you have more than one container, you can create a content data link between them."
"Prisma Cloud's monitoring features such as the compute compliance dashboard and the vulnerability dashboard, where we can get a clear visualization of their docker, have also been valuable. We can get layer-by-layer information that helps us see exactly where it's noncompliant. They update the dashboards quite frequently."
"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."
"It scans our containers in real time. Also, as they're built, it's looking into the container repository where the images are built, telling us ahead of time, "You have vulnerabilities here, and you should update this code before you deploy." And once it's deployed, it's scanning for vulnerabilities that are in production as the container is running."
"Overall, it gives us fantastic visibility into the cloud environment."
"I like Palo Alto's threat protection and Wi-Fi coverage. It has advanced features like DNS security and sandboxing. The automation capabilities are excellent."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"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 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."
"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."
"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."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"The cost of Qualys TotalCloud is high and could be more competitive."
"Their support could be improved."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"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."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"The remediation part could be better."
"The automation must continue to become much smoother."
"They should improve the user experience."
"For some custom policies, we need more features."
"The area for improvement is less about the product and more about the upsell. If we've already agreed that we'd like your product x, y, or z, don't try to add fries to my burger. I don't need it."
"When it comes to protecting the full cloud-native stack, it has the right breadth. They're covering all the topics I would care about, like container, cloud configuration, and serverless. There's one gap. There could be a better set of features around identity management—native AWS—IAM roles, and service account management. The depth in each of those areas varies a little bit. While they may have the breadth, I think there's still work to do in flushing out each of those feature sets."
"They need to make the settings more flexible to fit our internal policies about data."
"The training documentation provided for the two-hour boot camps is notoriously poor and disorganized."
"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 support is tricky to reach, so we would like better-oriented technical support enabled."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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."
 

Pricing and Cost Advice

"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 cost-efficient and was selected for its value compared to other products."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Prisma Cloud is a high-end enterprise solution, making it quite expensive."
"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 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."
"Although the cost can be high, the value is worth the price tag."
"In general, Prisma Cloud is much cheaper than cloud-native services."
"The cost depends on the pricing model. Compared to other solutions, the cost isn't that bad."
"It is fairly priced. However, its price can be better so that small banks or small organizations can afford it and adopt it to secure their environment and data."
"The pricing is competitive; for the most part, the security firms have similar prices."
"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."
"The product does not operate on a pay-per-license model."
"The solution's pricing is neither cheap nor very expensive."
"I rate the tool's pricing a three out of ten."
