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.

Long-term web protection has supported reliable traffic management but needs a simpler interface
NGINX App Protect is a good product. I have used both versions from F5 -also the free version- (I mean the NGINX/NGINX One/App Protect free trial period), and I think it is a good product. It's stable, affordable, and easy to manage. NGINX App Protect is a comprehensive security solution that combines advanced WAF, DoS protection, API security, and DevSecOps automation in a lightweight, scalable package ideal for modern cloud-native architectures. The adaptive machine learning capabilities are truly commendable, as the solution can establish traffic baselines and detect anomalies in real time. It automatically adjusts security policies, minimizing the need for manual intervention and reducing false positives. Additionally, it supports scalable deployment across diverse environments, including on-premises, cloud, Kubernetes, and containers, offering both flexibility and scalability I have experience with the web server, F5 load balancer, and similar products provided by Ergon, for eg. the web application firewall and the Microgateway for K8S. I'm also familiar with F5 BIG-IP products.

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

"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"The best part I like is the on-demand scans."
"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."
"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."
"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."
"Its dashboards are brilliant. It provides in-depth insights."
"I would rate Qualys TotalCloud ten out of ten."
"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."
"We use NGINX for security headers, and as a proxy; it is also a very good tool for load balancing."
"The tool is not complex and is very user-friendly."
"This solution is very much stable."
"WAF is useful to track mitigation, inclusion, prevention, and the parametric firewall."
"The most valuable feature is that there is a link in the system that will help to analyze the security of an application when something abnormal is found."
"I tested specific features and evaluated the solution against the Web Application Firewall. I conducted research to test different detection percentages. I did not use it directly for protection but for evaluation purposes."
"The most valuable feature of NGINX App Protect is the reverse proxy."
"NGINX App Protect is stable."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"Nessus scanner is very effective for internal penetration testing."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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."
 

Cons

"Their support could be improved."
"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."
"There is a lack of data segregation according to criticality or inventory."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"As far as scalability, it takes a long time for deployment."
"The dashboard could provide a more comprehensive view of the status of the connections."
"This solution is not really scalable. Both the virtual appliance and the physical appliance are limited in terms of how much traffic they can handle."
"Currently, the policies have to be handled manually, and you have to create from scratch, which can be a bit time-consuming, in a large environment."
"NGINX's technical support is good, but sometimes their response time is delayed, or they don't have the technical skills to resolve issues."
"It would be better if it were easier to implement and if there was more information from F5 regarding hardware requirements and specifications to deploy the service, to avoid disruptions after implementation."
"Right now, the tool doesn't provide an option revolving around update feeds, specifically the signature update option in the UI."
"The support from NGINX App Protect is too expensive."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The solution’s pricing could be improved."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The initial setup is highly complex."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
 

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."
"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."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"TotalCloud's price is about right where I would expect it to be."
