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

"Once you have your vulnerabilities fixed and your patches pushed out using Qualys TotalCloud, then you are able to eliminate threats and cyber risk."
"The scalability is good as well. I would rate it ten out of ten."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"In my opinion, this is the best tool."
"Qualys TotalCloud has improved our security posture."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"Visibility is a key feature. Integration with other technologies across the board, whether they are Palo Alto technologies, Windows technologies, or cloud technologies, is probably the biggest thing."
"It's definitely a good product, and if a company is heavily into the public cloud environment, they must look to use a product like this to gain good visibility into their security."
"The initial setup is seamless."
"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."
"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."
"Prisma Cloud's most valuable asset is its ability to provide detailed visibility into container activity."
"Overall, it gives us fantastic visibility into the cloud environment."
"The most valuable feature is its cloud security posture management."
"The strong security provided by the product in the container environment is its most valuable feature."
"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."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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."
"Nessus scanner is very effective for internal penetration testing."
 

Cons

"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"There is a lack of data segregation according to criticality or inventory."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"In terms of improvement, remediation still belongs to the cloud team, which is one of the issues we faced with Qualys TotalCloud."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"One of the requests is that Prisma Defender for the ECS solution is only supported for Linux. It does not support Windows."
"It would be nice Prisma Cloud merged its modules for CSPM and infrastructure as code. It would simplify the pricing and make it easier for customers to evaluate the solution because there are different modules, and you need to add it to your subscription separately."
"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."
"The initial setup was very complex."
"I believe there are some issues with the product's maturity. In some cases, it could malfunction concerning Cloud Native."
"Prisma Cloud supports generating CSV files, but I would also like it to generate PDF files for reporting."
"One definite area for improvement is the auto-remediation or the CWP area. The second one is the RQL language. It is still not very flexible and does not cover a lot of use cases. The RQL language could be dramatically improved to add more options."
"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?""
"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 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."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"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

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"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."
"The cost depends on the pricing model. Compared to other solutions, the cost isn't that bad."
"You can expect a premium price because it is a premium quality product by a leading supplier."
"The pricing is competitive. From what I have seen in the past, it is on par with the others."
"Its price is reasonable as compared to other products. The main challenge is explaining the licensing model to customers. It isn't a problem related to Palo Alto. Commonly, people don't understand cloud licensing or security licensing. When they have fixed virtual machines, they know what they are going to be charged, but when it comes to cloud automation, it is hard for them to get clarity in case of high workloads or when they have enabled auto-scaling, etc. It would be helpful if Palo Alto can educate people on their licensing programs."
"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 for Prisma Cloud is high. Providing a pay-as-you-go model or pricing options tailored for medium and small enterprises could help attract more clients."
"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."
"Prisma Cloud is remarkably expensive."
"The solution's pricing is neither cheap nor very expensive."
"I rate the product’s pricing a six out of ten."
"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."
