ROI

Sentiment score
4.9
Digital Guardian improved data protection, reduced breach risks, ensured compliance, saved money, and enhanced security and operational efficiency.
Sentiment score
3.6
NodeZero Platform cuts pen testing costs, enhances efficiency, reduces remediation time, and uncovers hidden network issues for revenue opportunities.
A reduction in remediation time has been seen because it is finding things before they happen.
Director of Enterprise Security at a energy/utilities company with 51-200 employees
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.

Customer Service

Sentiment score
6.1
Digital Guardian offers 24/7 global support with mixed reviews, praising quick responses but suggesting improved training for faster service.
Sentiment score
7.0
NodeZero Platform's customer service is highly rated for responsiveness and expertise, despite occasional licensing challenges and bandwidth delays.
For vendor support, such as Fortra support, I would rate it a seven because all the support comes from different parts that sometimes have challenges meeting time zones, and sometimes they reroute to distributors and rely on partners.
Cyber Security Researcher at a tech services company with 11-50 employees
Overall, when it comes to The NodeZero Platform's tech support, you can reach them via a chat message on their website, and they respond almost immediately.
Director of IT Security at a manufacturing company with 1,001-5,000 employees
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

Digital Guardian efficiently scales for various enterprises, handling up to 100,000 endpoints with minor regional deployment challenges.

The NodeZero Platform is scalable, supports Docker, and efficiently handles varied network assets, enhancing performance for diverse environments.
Regarding scalability, it is a 10 out of 10.

Senior Manager | Manager Security Services at RISK ASSOCIATES
 

Room For Improvement

Digital Guardian's partner program has insufficient support, complex deployment, resource-heavy agent, and lacks integration across platforms and services.
NodeZero Platform needs enhancements in vulnerability tools, scalability, reporting, and onboarding for improved user experience and integration.
The issue is that it works only with users or companies with more than 500 users.
Cyber Security Researcher at a tech services company with 11-50 employees
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
 

Setup Cost

Digital Guardian's pricing is higher but justified by advanced features and valued support for customized security needs.
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
 

Valuable Features

Digital Guardian ensures data security with data loss prevention, user activity tracking, and integration with advanced analytics and reporting.
NodeZero Platform offers automated tests, remediation guidance, and autonomous operation for streamlined, cost-effective vulnerability management with comprehensive reporting.
Digital Guardian can easily integrate with this data classification solution and has a very granular level of configuration and policy tuning.
Cyber Security Researcher at a tech services company with 11-50 employees
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.

Featured Reviews

Syed Mubeen - PeerSpot reviewer
Cyber Security Researcher at a tech services company with 11-50 employees
Enterprise data protection has supported regulatory compliance and integrates with classification tools
In terms of functionality, many features are valuable in Digital Guardian, as the first thing for most customers is that they are using solutions such as Boldon James and Titus, which fall under the classification side, and Digital Guardian can easily integrate with this data classification solution and has a very granular level of configuration and policy tuning. Digital Guardian's data protection policies are indeed useful for my clients. Regarding Digital Guardian, I find it to be a very good solution, and in fact, it is an enterprise-level solution that has very tight integration with most of the products, with Fortra but also with others.
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.
