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.

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."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"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."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"Its dashboards are brilliant. It provides in-depth insights."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"CoreOS Clair can be used by organizations of any size."
"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."
"CoreOS Clair's best feature is detection accuracy."
"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."
"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."
"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 is scalable."
"ExtraHop Reveal(x) 360 has positively impacted my organization by helping us detect abnormal activity on our network that we could not detect through our SIEM or XDR platform."
"Their technical support is more effective and of better quality than other competitors."
 

Cons

"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 areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"There is a lack of data segregation according to criticality or inventory."
"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."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"One challenge with ExtraHop Reveal(x) 360 is its pricing, which tends to be comparatively high in the marketplace."
"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."
"Their professional service can be improved."
"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."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive."
"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"The cost is high, but it meets our organizational needs."
"TotalCloud's price is about right where I would expect it to be."

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
