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.

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"The best part I like is the on-demand scans."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."
"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."
"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"
"CoreOS Clair can be used by organizations of any size."
"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"NGINX App Protect's best features are auto-learning, which creates a profile of applications that are deployed, bot protection, and force protection, which lets you configure your brute force policy and alert for and prevent brute force attacks."
"NGINX App Protect is a good product and performs very well even when it is under stress."
"The solution has helped us greatly during this Covid period."
"WAF is useful to track mitigation, inclusion, prevention, and the parametric firewall."
"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."
"It's very easy to deploy."
"NGINX App Protect has complete control over the HTTP session."
"The most valuable feature is that I can establish different services from the firewall."
 

Cons

"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"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."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"I think NGINX App Protect could be improved by having it come out of the box with NGINX."
"Areas for improvement would be if NGINX could scan for vulnerabilities and learn and update the signatures of DoS attacks."
"They could provide a better user interface."
"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."
"Setting policies and parameters through the UI should be more automated because the process is manual, where we can only edit one rule at a time."
"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."
"The configuration needs to be more flexible because it is difficult to do things that are outside of the ordinary."
"The solution does well when there's low throughput but when we go for any high throughput, it's always a challenge."
 

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."
"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."

"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
