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.

Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.

Proactive exploit intelligence has transformed how we prioritize real-world vulnerability risks
VulnCheck needs improvement in terms of data. It is primarily an intelligence and data layering system and not a complete vulnerability management platform. This means that it lacks native patch workflows, so you do not have asset discovery as you would with Tenable or Qualys. You will require other tools to act on the data that you find, which necessitates engineering time for API integration, data mapping, and tuning. Additionally, not all exploit signs are clear; some can be noisy or ambiguous, so teams need to apply their judgment. Finally, the time to value is not instant; it requires integration, workflow changes, and team training. I think VulnCheck is an excellent tool and valuable data resource. However, if you wish to send alerts via an API to platforms like Rapid7 or Tenable VM, you will need to integrate that with a SIEM solution to perform any kind of risk management.

Quotes from Members

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

Pros

"I would definitely recommend it because it is easy to handle any cloud resources."
"The best part I like is the on-demand scans."
"Qualys TotalCloud is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."
"Qualys TotalCloud has improved our security posture."
"Its dashboards are brilliant. It provides in-depth insights."
"Qualys TotalCloud's most valuable features are its cloud security posture management, Kubernetes, and container security capabilities."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by allowing my security team to be more efficient and focus on the most valuable work at the highest criticality."
"After the third party conducts the pen test, The NodeZero Platform is run, and it finds the same things they found and sometimes a few other things that they did not even identify."
"I rate the stability of the NodeZero Platform a ten out of ten."
"Penetration testing and scans are useful features."
"The NodeZero Platform by Horizon3.ai is better than manual penetration test scans, definitely worth trying if you are considering using it because it reduces the time and cost associated with manual scans and presents the data in a very clear way that even non-technical people can understand."
"The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization."
"The clear prioritization based on risk is probably the biggest day-to-day benefit."
"VulnCheck has shifted the mindset within my organization and my partners from a reactive to a more proactive approach."
"With VulnCheck's early exploit visibility, I can remediate vulnerabilities quickly, making timely decisions before the vulnerabilities are known to the public and hackers."
 

Cons

"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 support process is inefficient due to the excessive number of replies required when submitting tickets."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"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."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"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."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"When it comes to the stability of The NodeZero Platform by Horizon3.ai, I would rate it around seven to eight because the stability is not that high initially due to the need for daily updates and modifications as new vulnerabilities appear."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"The NodeZero Platform by Horizon3.ai could be improved by reducing the elapsed time from identifying a zero-day vulnerability from their QA environment to their production environment."
"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."
"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."
"Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes."
"I haven't really come across anything that I say needs to be improved with it, other than the container runner, which tends to lose time."
"VulnCheck needs improvement in terms of data."
"VulnCheck's UI and reporting can be improved for better visibility."
