Cybersecurity just got more real. Horizon3.ai is bringing autonomous, AI-driven penetration testing straight to the MSP and MSSP toolkit—no heavy lifting, no middleman. And now it’s all available on the Pax8 cloud marketplace.
Key Takeaways:
- NodeZero is now live on the Pax8 Marketplace, offering AI-powered pentesting to MSSPs and MSPs.
- No red team needed: Service providers can emulate real-world cyberattacks continuously and autonomously.
- Direct integration means no procurement hurdles, accelerating adoption and boosting partner revenue.
- Market demand is exploding, with automated BAS tools projected to hit $10.5B by 2033.
- Horizon3.ai’s aggressive channel strategy includes a new partner program, federal certifications, and $100M in new funding.
Horizon3.ai is doubling down on growth
This time by putting its flagship NodeZero platform into the hands of thousands of managed service providers via the Pax8 Marketplace.
The San Francisco-based cybersecurity startup announced that NodeZero, its autonomous penetration testing tool, is now available to buy, deploy, and scale on Pax8—a top cloud commerce platform trusted by MSPs and MSSPs globally.
For MSSPs and MSPs juggling multiple clients and mounting cyber threats, this is more than a tech update—it’s a game-changer.
“Pax8 gives us reach into the MSP ecosystem without friction,” said Marc Inderhees, VP of channels and alliances at Horizon3.ai. “No procurement hurdles, no heavy lift. For our partners, it’s a whole new revenue stream.”
And he’s not exaggerating.
NodeZero doesn’t just scan systems—it attacks them (safely). The platform uses artificial intelligence to simulate real-world hacker behavior, testing networks, apps, and configurations for actual exploitable paths, not theoretical ones. It documents every step and delivers concrete proof of risk, helping clients prioritize fixes that matter.
The tool is designed to flip traditional, reactive cybersecurity on its head. Instead of waiting for alerts and hoping your firewall holds, NodeZero shows you exactly where you’re weak—before an attacker does.
“Organizations don’t need more alerts. They need proof,” Inderhees explained. “This is how MSPs move from passive monitoring to active security.”
Why It Matters Now
Offensive security tools—like breach and attack simulation (BAS) and adversary emulation—have traditionally been reserved for large enterprises with deep budgets and in-house red teams. That’s changing. Horizon3.ai is breaking down those barriers with automation and accessibility.
According to market forecasts, the automated BAS industry is expected to balloon from $953 million in 2025 to over $10.5 billion by 2033. With cyberattacks growing in scale and sophistication, the demand for real-world testing is only accelerating.
“Scanning and patching alone aren’t enough anymore,” notes a blog from rival firm XM Cyber. “You need continuous visibility across your environments.”
With NodeZero, MSSPs and MSPs can now offer “pentesting as a service,” validate patches, simulate intrusions on demand, and demonstrate tangible risk reduction—without spinning up a red team.
Horizon3.ai’s Aggressive Expansion
The company isn’t slowing down. In just the last few quarters, Horizon3.ai has:
- Released pentesting for Kubernetes,
- Launched NodeZero Tripwires for deploying decoys, and
- Introduced NodeZero Insights, which unifies test data across time.
On top of that, it unveiled a Vanguard Partner Program, achieved FedRAMP High Authorization (letting it sell to U.S. federal agencies), and closed a $100 million funding round, adding to the $40 million Series C it landed in 2023.
NodeZero is already in use by over 3,000 organizations, and the company is scaling fast—expanding in North America, EMEA, and Asia-Pacific.
“Our partners are starting to act as the offensive security team for their clients,” Inderhees said. “And now that NodeZero is on Pax8, they can plug it right into their stack and start delivering results immediately.”
For MSSPs and MSPs looking to differentiate and deliver measurable security outcomes, this move gives them a serious edge.
