What People Are Saying About Horizon3.ai

"NodeZero has given our organisation the ability to conduct penetration testing in a reliable, repeatable, affordable manner."

Senior IT Security and Risk Specialist


"My overall experience has been very positive, from the deployment of the NodeZero to conducting the operation to interpreting the results."

IT Security and Risk Management


"This is the rockstar for pentesting, an indispensable tool which lets you kick off pentests as simple or complex as you want with the push of a button. The implementation was smooth and the support is great, the pentests you can run are very frequently updated"

IT Security & Risk Management Associate


"This product is in a unique and growing space and stands out strong beyond all others. The utility of this system can substantially increase your security posture."

– IT Services


"The setup and deployment of this product is pretty straightforward and easy to do. You can have this up and running in a very short amount of time and finding vulnerabilities in your environment before someone else does and shuts you down."



"Great product, that is simple and easy to use. Truly great support and team behind the scenes as well."



"Ease of setup. Linux box with docker, then access to the portal. Not hard at all for any busy professional."



"I have been in IT/Security since 1997 and over the years I have seen multiple penetration testing tools. Node0 by far is the best pen-test tool I have used. The experience and technical ability that Horizon3 brings to the table is outstanding."

IT Security and Risk Management


"Our initial trial was so impressive, we committed to a year contract to leverage this product to improve our security stance. After paying for an external pen test and being able to compare the results of both, this product was superior in many ways."



"Overall, the product is great! Would like to see some more API expanded capabilities (i.e. pulling additional CSV reports from the engagement - same as what is currently available in the portal)."

IT Security and Risk Management


"This helps elevate my team and takes away some of the most time-consuming tasks and automates them. Can't ask for much more."

IT Security and Risk Management


"This has really enlightened us on where we need to improve on the infrastructure of our business."



"The software was remotely fully installed and operational within 15 minutes "



"The kill chain that Horizon3 presents is great for being able to show the C-suite and talking them through WHY they should spend money to fix something."



"We can now run our required internal penetration testing without a dedicated resource."
