About Company

Company Description

Updated 24th January 2024

Horizon3.ai is a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, "checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Founded in 2019, Horizon3.ai is headquartered in San Francisco, CA.

NodeZero Likes & Dislikes

Like

The solution is deployed in the cloud which provides great flexibility and eases the roll-out of the service in different parts of the company network. The product also gives proof-of-concept commands that can be run to verify the claimed findings. Since it uses mainly open source tooling, it is possible to audit the tool's code which is appreciated in comparison with running lots of proprietary programs.

Dislike

Cannot schedule a job to only run once and how it interprets accounts sharing passwords. There seems to be a bug where it assumes many accounts are sharing the same password.
