Horizon3 NodeZero pricing

Horizon3 pricing for NodeZero is published as a list: $15 per asset per test on Flex, $50 to $85 per asset per year on the three subscription tiers, and $10,000 per app per test for web application testing. All figures come from the vendor's pricing page, which we checked on 9 November 2026. The unit is a discovered asset, so the total depends on a count you may not have yet.

What is the price unit, and what does it buy?#

The unit is a discovered asset: a server, device, cloud resource or service. It is not a test or an engagement. A machine found under several names counts as one asset.

Flex charges each time an asset is tested. Core, Pro and Elite charge each asset once per 12 months and then allow unlimited testing. WebApp is the exception: it is priced per app, and the page does not say what one app test covers.

This differs from per-test prices such as the ones in our penetration testing cost guide, so the figures cannot be compared line by line.

What costs extra or is not stated?#

Support tiers cost extra. The pricing page lists Enhanced at 10% of the subscription with a $7,500 yearly minimum, and Premier at 20% with a $25,000 yearly minimum.

In the example above, 10% of the Core subscription is $1,000, so the $7,500 minimum would apply. Ask whether the minimum applies when you buy Flex, because the page describes support as a percentage of a subscription.

Other open points:

• The asset count is known only after discovery. A larger network than you expected raises the bill.
• WebApp Flex does not define what one test covers, such as the number of roles or pages.
• WebApp Continuous is priced per app on request. No amount is published.
• Third-party price ranges and "median" figures from resellers are not vendor prices. We do not use them.

What do retests and turnaround look like?#

Findings include fix actions with a one-click verify. On Core, Pro and Elite, retests carry no extra charge because testing is unlimited. For Flex, the page does not say whether a verify counts as a new billed test.

No turnaround time is published. The WebApp page says tests can be set up quickly and run as often as needed, with no start time, test length or report time. No sample report is published either, so you can judge the output only in a trial or demo.
