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.

Provides network mapping feature for visualizing container communication but complex setup

There is room for improvement in the setup process. All these tools come down to how you're integrating into your environment and having good knowledge of the tool. So that's the biggest problem with all these security tools – you gotta have knowledgeable people to build, integrate, and really flesh them out in your environment to make them work as they should.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments

Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.

Cons

"The price is very expensive, actually."

"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."

"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."

"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."

"The support and specifications need to be up to date for the cluster technologies"

"The solution's visibility and vulnerability prevention should be improved."

"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."

"Red Hat is somewhat expensive."

More Red Hat Advanced Cluster Security for Kubernetes cons

"I didn't find anything that wasn't useful or needed to be added."

"We still maintain Tenable Cloud Security but have reduced the number of licenses. We now use it occasionally to validate specific items rather than monitoring the entire surface, for which we use Element."

"I have faced several bug incidents with the solution"

"Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product."

"The product must provide more features."

"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."

"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."

"There is a need for the support team to improve their response time since it is one of the areas where the product's technical team has certain shortcomings."
