BJ
Technical Director at Entrust Software Development India
Centralized security testing has improved vulnerability remediation and compliance reporting
I recommend more enhancements focusing on penetration testing for both SSL over HTTP and non-SSL over HTTP, specifically targeting the RCP Rich Client Platform and Equinox frameworks that allow on-premises desktop applications to be tested simultaneously. I believe those would significantly improve the tool in the future. I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities. Once we build this installer—rather than just working on the codebase—sometimes, we face gaps considering the build parameters and conversions to the installer. Identifying those gaps is an area that could use improvement after the installer or desktop application testing, which would be beneficial. That is the only reason; otherwise, I could easily rate it a ten out of ten given its smooth operational process.

A centralized tool for vulnerability and misconfiguration management in a multiple cloud environment
Qualys TotalCloud provides written explanations to help guide the remediation paths and eliminate cyber risk. We are using TruRisk for the remediations. The TruRisk shows anything critical, and we can then focus on that. We also assess manually whether an asset is a critical target or not. Qualys TotalCloud provides a single, prioritized view of risk. We are using CIS-CAT standards to harden our clouds, such as AWS, Google Cloud, and Azure. We are able to analyze the scans and identify which policies have failed and how we can remediate them. We can customize policies as per our organization's requirements. That is very helpful for us. With the TruRisk Insights feature, security has significantly improved. In six months of using it, we see that everything is under control. We've solved many problems related to asset management, cloud configuration, and the new asset identification. If an application team has onboarded any cloud asset, we can see that. We have that information now.

Quotes from Members

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

Pros

"I think the best features that Nucleus Security offers are purely the faster remediation to dev tools, which is crucial for managing, prioritizing, and fixing vulnerabilities while helping operational pipelines run these vulnerability management tools."
"We have seen clear compliance and risk control outcomes more than other operational metrics, including fewer process gaps during documentation and safety checks, strong consistency in following protocols for handling, traceability, and staff awareness, better audit readiness, a lower chance of procedure errors, and faster escalation when something appears out of standard, which is very important for us in the healthcare sector."
"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 provides the easiest and the best approach for cloud infrastructure management."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"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"
"I would definitely recommend Qualys TotalCloud to other customers."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
 

Cons

"Protocols can be too complex in practice sometimes, and some processes can feel heavy and disconnected from our daily workflow."
"I choose eight as my rating primarily because of the installer app; it becomes challenging to identify the actual vulnerabilities."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested."
"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."
"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."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
