Horizon3 alternatives: NodeZero rivals by price unit

Horizon3 alternatives depend on what you are replacing. NodeZero is autonomous software priced per discovered asset, so its closest rivals are other platforms, and per-test AI services or consultancies are a different product class. This page groups four alternatives from the provider dataset by delivery type and price unit, using vendor pages checked on 9 November 2026.

Why do teams look for Horizon3 alternatives?#

Three reasons come up in the dataset notes. The first is the price unit. NodeZero bills per asset, and an asset is a discovered server, device, cloud resource or service. Your total depends on an asset count that is not known in advance.

The second is scope. The pages checked do not mention mobile testing, and they describe no human review of findings. The third is evidence: Horizon3 publishes no sample report.

None of this makes NodeZero a poor fit. The dataset describes it as a fit for security teams that test internal and external networks, cloud and Active Directory often and can count their assets.

How does Horizon3 sell NodeZero?#

NodeZero covers internal, external, cloud (AWS and Azure) and Kubernetes pentests, plus a newer web application module. List prices are public on the pricing page.

Core adds scheduling and unlimited testing. Pro adds tripwires and rapid response. Elite adds insights, high-value targeting, advanced data pilfering, threat actor intelligence and vulnerability prioritization. Support tiers cost extra: Enhanced is 10% of the subscription, minimum $7,500 per year, and Premier is 20%, minimum $25,000 per year.

The full breakdown is on our Horizon3 pricing page.

Which alternatives fit by delivery type?#

Group the options by who or what does the testing.

NodeZero is a different product class from a consultancy. A platform runs repeated tests on your assets for a subscription. A consultancy sells a scoped engagement and a report. Pick the class first, then compare vendors inside it.

For platform comparisons, our Pentera alternatives and NodeZero vs Pentera pages already cover that ground. We link to them and do not repeat them here.

What do the closest alternatives say about themselves?#

Pentera sells the Pentera Platform with Core (internal), Surface (external) and Cloud modules, plus AI-native web app and API testing and human-led adversarial testing. It lists no prices. Its homepage offers only "Talk to an Expert" and a demo. It states no turnaround and offers no sample report.

XBOW runs many AI agents against web applications and APIs and validates findings with exploits. Its pricing is usage-based with no unit or amount. It describes first validated findings in hours, and free, unlimited retests. See the XBOW alternatives and XBOW vs Horizon3 pages.

Hadrian lists Nova tests from EUR 1,250 per test, excluding VAT. Its scope names web applications, and one test is not defined. Intruder lists $3,500 per test, a $12,000 four-test pack, and $4,000 on its AI Pentesting page. Its AI pentest covers web apps only and offers unlimited retesting on the single test and the pack. Aikido lists $4,000 per assessment and $50 to $30,000+ for Rightsized. See Aikido pricing.

How do the options compare side by side?#

"Not published" means the vendor's pages do not show the item. It may still exist on request.

Which alternatives publish prices, and how do you choose by scope and budget?#

Hadrian, Intruder and Aikido publish prices you can use for a budget. The per-asset and per-test units do not convert directly. A 500-asset network at $50 per asset is $25,000 a year of unlimited testing. A $4,000 web app test is one scoped run.

Use this decision order:

1. Network, cloud or Active Directory coverage, tested often: look at platforms (NodeZero, Pentera).
2. One web app or API before a release, with a fixed price: look at per-test services (Hadrian, Intruder, Aikido).
3. A named human reviewer or an auditor-facing report: ask providers for a sample report first, and see the sample report guide.
