Being able to find them because there have been no eyes on that particular section so far ever, and fixing those potentially prevented those companies from getting breached.
IT Security Consultant at Systemhaus for you GmbH
So far, I have seen a return on investment with The NodeZero Platform by Horizon3.ai, as we managed to save a lot of time and effort with this because this is an autonomous tool, and our manual effort is significantly reduced because of a product of this type.
Senior Manager | Manager Security Services at RISK ASSOCIATES
There was a specific issue that our other security tooling did not pick up, but XM Cyber did.

Previously, with time-sensitive engagements, I would worry about resolving issues before deadlines. That concern has diminished as they've become more responsive and require less escalation to engineering.
Principal Consultant at JTI Cybersecurity
The vast majority of times they are able to resolve the exact questions my team has on the first attempt, which is really good for customer or technical support.
Chief Information Officer at a construction company with 1,001-5,000 employees

We have quite a complex and large IT estate, and we've certainly experienced no limitations or problems arising from the ability of XM Cyber's product to scale across that estate.
Chief Information Security Officer at a financial services firm with 5,001-10,000 employees
 

Room For Improvement

NodeZero Platform needs enhancements in vulnerability tools, scalability, reporting, and onboarding for improved user experience and integration.

This service reveals which credentials and email addresses are available on the deep web, as well as which domains have been set up using typo-squatting techniques.
Information Security Manager at a non-profit with 51-200 employees
The one thing that is very much asked from us as a service provider is DAST testing, so when a company is building a software, they could see their current security status while they are building the application.
Offensive Security Analyst at a tech services company with 201-500 employees
One of the areas where improvement is needed is in the visibility and reporting for large enterprises.
CEO at cybovate
We push the boundaries with digital twins; I understand XM Cyber uses a similar concept of graph databases to map environments.
Group CISO at a insurance company with 51-200 employees
They could improve support because when we need to create a super case and escalate to resolve with technical support, they resolve our ticket in approximately two weeks.
Chief Information Security Officer at Prezero
The part that can be improved is the mobile exposure and the IBM i specific equipment.
IT Security manager at a tech services company with 10,001+ employees
 

Setup Cost

Enterprise buyers find NodeZero Platform pricing competitive, cost-efficient, and flexible with IP-based licensing and low setup costs.
The pricing is much more affordable than traditional penetration tests.
Manager, Information Technology at a performing arts with 11-50 employees
It's a bit cheaper than manual penetration testing because manual testing typically allows you to scan only a few subnets.
Works at a hospitality company with 201-500 employees
Usually, manual penetration test scans take considerable time and money.
Security Engineer at Herjavec Group
We have a large, complicated estate, and in the licensing discussions, we were keen not to have the cost balloon because of the complication, the number of PCs and servers that we have.
Chief Information Security Officer at a financial services firm with 5,001-10,000 employees
 

Valuable Features

NodeZero Platform offers automated tests, remediation guidance, and autonomous operation for streamlined, cost-effective vulnerability management with comprehensive reporting.
XM Cyber enhances security by simulating attacks, assessing risks, identifying vulnerabilities, and optimizing asset protection with metrics and cost savings.
When a new vulnerability, such as a zero-day exploit, is identified, they review your previous scans to determine if you might be vulnerable to it, and they proactively notify you.
Director of IT Security at a manufacturing company with 1,001-5,000 employees
The detailed reports not only list the vulnerabilities that matter, but they also include direct links to patches.
Information Security Manager at a non-profit with 51-200 employees
The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems.
Chief Information Security Officer at a construction company with 1,001-5,000 employees
Our loss exposure amount has reduced significantly, leading to two big wins: our loss exposure amount has gone down, and we have direct savings from focusing our team's time on what's important, allowing them to work on other business benefits and generate value for the company.
Group CISO at a insurance company with 51-200 employees
By far, the best feature of XM Cyber is being able to map out the way vulnerabilities can be exploited based on what they call the choke points in the network where the path that a bad actor would take comes closest to assets within our environment that are most vulnerable but also most valuable.
Chief Information Security Officer at a financial services firm with 5,001-10,000 employees
XM Cyber allows us to quantify the risk, and we are able to track remediation, so we can quantify the risk at an executive level and also to a technical IT team.
IT Security manager at a tech services company with 10,001+ employees

Featured Reviews

Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
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.
Stephen Owen - PeerSpot reviewer
Group CISO at a insurance company with 51-200 employees
Has significantly improved risk visibility and optimized remediation efforts across dynamic environments
We tightly integrate with APIs, consuming feeds and open source data. We have integrated with XM Cyber, and we are elevating ourselves with AI and MCP tools as we view this as a forerunner to reducing the workload for our agents and IT staff. We're pushing all our security partners to provide AI and MCP tools. Our vision is for them to offer a chat interface where a junior IT or an experienced infrastructure engineer can ask for what needs to be patched next without using an interface. Their current interface is very usable and professional, ranking in the top tier of applications. Their reporting is good, offering custom reports, and their API integration is a new capability that serves us well. We have high expectations for the next generation, such as a chat interface to ask questions. However, everything has been very good. We push the boundaries with digital twins; I understand XM Cyber uses a similar concept of graph databases to map environments. I would like access to that and querying languages, enabling more informed business decisions. XM Cyber sees much of our estate, which is beneficial for making informed decisions, and we can harness those insights and data for business analytics. For instance, it could help us gain insights into change management—if a particular server impacts another and that server is supported by yet another server, we could glean significant insights for change management meetings.
