Horizon3 and Pax8 Expand Partnership to Bring Autonomous Security Testing to MSPs Across Europe

NodeZero® gives partners a repeatable way to identify exploitable attack paths, guide remediation, and prove fixes worked

AMSTERDAM, October 16, 2026--Horizon3, the AI-Native Proactive Security Company, today announced the expansion of its Pax8 partnership across Europe, bringing the NodeZero® Proactive Security Platform to the region's managed service providers (MSPs) through the Pax8 Marketplace. The expansion enables partners to build recurring security services that help small and midsized businesses understand how attackers could compromise their environments, prioritize corrective actions, and verify remediation.

Building on the companies' North American marketplace launch, the European expansion makes autonomous offensive security testing accessible to more MSPs and the businesses they protect. Partners can use NodeZero to deliver initial assessments, support remediation engagements, and establish ongoing testing programs without conducting every penetration test manually.

"MSPs are accountable for protecting their customers' security, but a list of vulnerabilities does not tell them what is actually exploitable, and their level of exposure," said Keith Poyser, General Manager & SVP EMEA, at Horizon3. "NodeZero gives partners that information and a way to fix, and then verify these exploits are remediated. Expanding our relationship with Pax8 brings this capability to more MSPs across Europe, helping them build services around measurable reductions in customer exposure and continuous testing."

From Individual Weaknesses to Proven Attack Paths

NodeZero autonomously tests production environments using real attack techniques within defined scope and safety controls. Its capabilities span internal and external infrastructure, cloud, and web applications, helping teams understand how exploitable weaknesses can lead to unauthorized access, privilege escalation, and exposure of sensitive data.

Rather than treating each finding in isolation, NodeZero chains weaknesses to demonstrate attainable attacker impacts. Results include evidence of successful exploitation, documented attack paths, and prioritized remediation guidance, giving partners a clear basis for recommending what customers should address first.

NodeZero WebApp extends this approach to custom, business-critical web applications. It supports authenticated testing to uncover exploitable application weaknesses, including broken access controls and business logic flaws, helping teams assess risks that scanning alone can miss.
