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.

Unified vulnerability management has strengthened credential defenses and improves risk-based decisions

I believe Unified Vulnerability Management can improve by emphasizing continuous monitoring, which necessitates a dashboard for users. Creating more mobility, especially since many incidents occur outside regular hours, would be beneficial. If anything goes wrong, a mobile version or mobile dashboard could be extremely helpful. Mobility is now a mandatory capability, allowing users to manage vulnerabilities through mobile applications. Beyond mobility for Unified Vulnerability Management, more flexibility is also required. For example, vulnerability scanners routinely scan and create reports. It would be beneficial if I could create a runbook so that if any unwanted events occur, it generates alerts and stops operations. This would create a complete package for secure posture and management, allowing me to protect not just through scans but also through prevention.

Quotes from Members

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

Pros

"I believe that The NodeZero Platform by Horizon3.ai has kept me safer in a cybersecurity sense."

"The best feature of The NodeZero Platform by Horizon3.ai is that it is an autonomous pen testing tool that knows how to penetrate into the system automatically and perform lateral movement inside the network without the need for scripting."

"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."

"The NodeZero Platform by Horizon3.ai has allowed us to quickly and easily identify the exploits in our environment that are greatly increasing our risk, simplified that process and also our remediation process, allowing us to more easily work with teams to show how it is exploitable and what they need to do to fix those issues, significantly improving our finding discovery and remediation process of vulnerabilities and overall decreasing our risk."

"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."

"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."

"Otherwise, the solution itself is very fine and I would recommend it as an MSP partner or as a user of the tool to pretty much any company."

"If someone was looking into this product, I would absolutely recommend it."

More The NodeZero Platform by Horizon3.ai pros

"Based on my experience, the visibility and zero trust that Unified Vulnerability Management provides brings the biggest benefit."

"Unified Vulnerability Management has centralized the process of identifying, assessing, prioritizing, remediating, and monitoring vulnerabilities across my organization's entire IT ecosystem through a single integrated platform and governance framework, making this the most significant advantage."

"Unified Vulnerability Management has positively impacted my organization by improving our response time to vulnerabilities significantly, reducing our average response time by 40% and delivering measurable improvements in our security posture."

"For me, the most appealing aspect of Unified Vulnerability Management for a customer or potential customer is the functionality."

"The best feature of Unified Vulnerability Management is that it never shows actual details publicly and provides different virtual information to those coming from outside the company."

"Unified Vulnerability Management gives a good overview and detailed visibility of all traffic, which allows me to easily find bottlenecks or issues."

"In Unified Vulnerability Management, the best features include the ability to consolidate each and every device without dependency on other patch vulnerability management software, such as Qualys and SolarWinds, which have limited modules."

Cons

"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."

"The setting up of new runners in The NodeZero Platform by Horizon3.ai could be simplified a little bit; currently, it's kind of a three-step process where you have to set up the assets in a separate menu, then a separate menu to set up a template, and then you actually set up the runner, so it would be nice if from the runner creation screen it just took you through the whole process instead of having to navigate to three different tabs."

"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."

"We did hundreds of tests, so that is why we did not continue, as it was very expensive for a very low yield."

"I feel there could be improvements in scalability, although at this point I have no specific negative points to report."

"Sometimes even their support doesn't know why we're seeing certain issues."

"However, my team struggles with the onboarding side of our engagement, which should have been more robust; having a statement of work and a clear definition of success would have been beneficial."

"The NodeZero Platform by Horizon3.ai could be improved by speeding up the time from initializing a test to actually starting the test, as the deployment of the underlying infrastructure can take several minutes, sometimes over 10 minutes."

More The NodeZero Platform by Horizon3.ai cons

"Improvements are necessary because Unified Vulnerability Management has been in the market for only seven or eight years, and a lot of improvement must be required for performance."

"More AI features would be welcome, and the price should be lower because it is becoming more expensive, and customers are already looking for alternatives because of the pricing."

"Customer support varies. After COVID, I find customer support lacking, and I am not sure why the principals do not prioritize it more."

"I cannot rate Unified Vulnerability Management in general from one to ten because I have not implemented the product."

"In Unified Vulnerability Management, the area that needs improvement is DNS-level security, which has been lacking for the last ten years."

"The negative side of Unified Vulnerability Management is that you need a skill set that is not readily available."

"I believe Unified Vulnerability Management can be improved by refining its reporting capabilities."
