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.

Cloud-native threat detection has improved incident investigations and now reduces breach risk
We have covered most of the features over the past three years and look forward to discovering more as we work closely with the ExtraHop technical team, who are open to sharing what they have developed. Pricing is on the higher side, typically based on load, volume of traffic, and deployment scale. The advanced detection capabilities provide significant value in reducing investigation time, making the licensing and pricing acceptable for larger organizations. ExtraHop Reveal(x) 360 has undeniably improved our security posture, reduced manual investigation efforts, and facilitated fast threat detection mechanisms, which all help prevent costly potential breaches in enterprise environments. ExtraHop Reveal(x) 360's SaaS environment is well-suited for cloud, on-premises, and hybrid environments, effectively addressing real-life scenarios involving east-west and north-south traffic. The platform is recommended for large organizations in need of comprehensive detection capabilities. I would rate this product overall as an 8 out of 10.

"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.

"ExtraHop Reveal(x) 360 has undeniably improved our security posture, reduced manual investigation efforts, and facilitated fast threat detection mechanisms, which all help prevent costly potential breaches in enterprise environments."
"It stands out for its intuitive and efficient user interface, robust detection capabilities with minimal false positives, and the ability to handle encrypted traffic, making it a valuable asset for network security and management."
"It is scalable."
"It is very easy to collect and handle data in ExtraHop Reveal(X) Cloud. Integration with Big Data is also easy. Many of our customers integrate it with Big Data platforms like Splunk or Elastic. It is also easy to handle and easy to understand."
 

Cons

"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."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"The support is not up to the mark and seems to be overburdened."
"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."
"The price is very expensive, actually."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"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."
"A drawback includes bucket storage limitations for payload data, necessitating timely extraction for thorough investigations."
"There needs to be more support."
"I would like to see ExtraHop Reveal(x) 360 improved by integrating XDR features with NDR."
"Their professional service can be improved."
"They can include integration with SAP. Currently, no vendor provides network performance monitoring in the SAP market. It is a very big market. We have around 400 customers for SAP in Korea. In the USA, there are more than 10,000 customers."
"One challenge with ExtraHop Reveal(x) 360 is its pricing, which tends to be comparatively high in the marketplace."
 

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
