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

"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"Qualys TotalCloud fulfills all these needs."
"We have seen a return on investment using NGINX App Protect."
"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."
"Based on my experience, this solution is better than the other choices on the market."
"We were looking for a product that is capable of complete automation and a container based solution, and it's working."
"I would recommend this solution to others because it performs well."
"The solution is very good overall."
"NGINX App Protect has positively impacted my organization by adding an additional layer of security on top of my infrastructure layer, which I consider quite helpful."
"It's very easy to deploy."
"The strong security provided by the product in the container environment is its most valuable feature."
"It is a scalable solution. Scalability-wise, it is a good solution."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Nessus scanner is very effective for internal penetration testing."
"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."
 

Cons

"There is a lack of data segregation according to criticality or inventory."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"The cost of Qualys TotalCloud is high and could be more competitive."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"The setup of NGINX App Protect is complex. The full process took one week to complete. Additionally, we had to change the network infrastructure platform which took one month."
"The dashboard could provide a more comprehensive view of the status of the connections."
"It doesn't have more advanced features like no false-positive security, which you can configure in Advanced WAF."
"The integration of NGINX App Protect could improve."
"NGINX's technical support is good, but sometimes their response time is delayed, or they don't have the technical skills to resolve issues."
"Its technical support could be better."
"It's challenging if you need to go for a high throughput."
"Areas for improvement would be if NGINX could scan for vulnerabilities and learn and update the signatures of DoS attacks."
"The initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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 feel that in certain areas this product has false positives which the company should work on."
"The solution’s pricing could be improved."
"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."
"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. 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."
