"Intuitive Yet Powerful—A Critical Part of Our Cybersecurity Toolbox"

5/5

What do you like best about NodeZero from Horizon3.ai?

It is both intuitive and thorough with easy integration and implementation. During product review, NodeZero became an obvious choice because interaction was simple enough for our nontechnical personnel to follow yet the platform capabilities matched those of skilled professionals. The company has VERY responsive customer service and keeps up with the most recently discovered vulnerabilities and offers rapid release of testing against them. This has become a highly used and critical part of our cybersecurity toolbox. Review collected by and hosted on G2.com.

What do you dislike about NodeZero from Horizon3.ai?

The only issue is something I just discovered and have not brought to their product team yet. Tripwires doesn't report the specific machines it failed on and succeeded on in an obvious manner. Review collected by and hosted on G2.com.

"Essential for Compliance and Flexibility"

5/5

What do you like best about NodeZero from Horizon3.ai?

I really like the service and attention that NodeZero from Horizon3.ai offers. The platform's CMMC aligned guidance is great, providing us with the necessary support to comply under CMMC and covering those pentest controls. I appreciate the flexibility to run focused or ad hoc tests, which is invaluable for us. The expertise of the team is unmatched, and I couldn't have chosen a better company. You all are great, and Will is particularly excellent. The initial setup was very easy too. Review collected by and hosted on G2.com.

"Fast, Accurate and Affordable"

5/5

What do you like best about NodeZero from Horizon3.ai?

Finding the misconfigurations that have been inherent to an environment for years. Finding weaknesses that I didn't realize were an issue. Finally the ability to be alerted by Rapid Response for existing new vulnerabilities that are exploitable. Review collected by and hosted on G2.com.

What do you dislike about NodeZero from Horizon3.ai?

No downside. If there is one part that I would like more out of is the application testing (specifically on the external pentests) Review collected by and hosted on G2.com.
