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

"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"I would definitely recommend Qualys TotalCloud to other users."
"Qualys TotalCloud has improved our security posture."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"In my opinion, this is the best tool."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The scalability is good as well. I would rate it ten out of ten."
"This solution is very much stable."
"The tool is not complex and is very user-friendly."
"The solution is very good overall."
"The most valuable feature of NGINX App Protect is its flexibility."
"The tool's most valuable feature is the OWASP certification. Additionally, the tool's ability to enforce strong passwords and OTP within minutes is impressive. With its analytics and recommendations, it is a very good solution."
"The solution has helped us greatly during this Covid period."
"I really love NGINX App Protect; I love the functionality, the ease of implementation, the very user-friendly Instance Manager, and its integration with DevOps, and as an NGINX Ingress controller using the Plus certificate it is working perfectly and making things a lot easier than the regular one while successfully stopping threats like injection, running scripts, and SQL injections."
"This solution provides perfect protection for the published services against all application attacks."
"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."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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 tool's most valuable feature is scanning, reporting, and troubleshooting."
"Nessus scanner is very effective for internal penetration testing."
 

Cons

"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."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"One of the things that could be improved is the alerts. Qualys is a fantastic tool, especially with the TruRisk feature, but one challenge that most leaders face involves alert fatigue."
"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"Areas for improvement would be if NGINX could scan for vulnerabilities and learn and update the signatures of DoS attacks."
"Its technical support could be better."
"I think NGINX App Protect could be improved by having it come out of the box with NGINX."
"The dashboard could provide a more comprehensive view of the status of the connections."
"The product's price is high, making it an area of concern where improvements are required. The tool's licensing model is also not good."
"NGINX's technical support is good, but sometimes their response time is delayed, or they don't have the technical skills to resolve issues."
"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."
"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."
"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. 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 initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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 solution’s pricing could be improved."
"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."
