Continuous Pentesting as a Service
Test like an attacker. Every week, not every year.
Autonomous, fully managed penetration testing powered by Horizon3.ai NodeZero. We find exploitable paths through your environment, help you fix what matters most, and verify the fix — on your schedule.
What gets tested
How it works
Autonomous testing. Human judgment.
NodeZero does the attacking. Our team makes the results useful to yours.
- 01Scope & onboardWe agree on targets, cadence and rules of engagement, then deploy with minimal effort from your team.
- 02Attack safelyNodeZero chains misconfigurations, weak credentials and vulnerabilities the way a real adversary would.
- 03Prioritize & fixOur analysts review every finding and walk your team through what to fix first, and why.
- 04Verify & repeatRe-test to prove each fix holds, then keep testing as your environment changes.
Annual vs. continuous
A snapshot can't keep up with a moving target.
| Annual pentest | Legion continuous | |
|---|---|---|
| Frequency | Once a year | As often as you need — weekly or monthly |
| Fix verification | Wait for next year's test | Re-test immediately |
| Coverage of change | Misses everything after test day | Catches new exposure as it appears |
| Compliance & insurance | Point-in-time report | Ongoing evidence for PCI, HIPAA, DORA and underwriters |
Need to go deeper?
Pair it with expert-led testing.
Continuous testing keeps your baseline honest. For complex applications, APIs or a realistic adversary scenario, our testers go hands-on.
Common questions
Is it safe to run in production?
NodeZero is designed to run safely against production systems. We agree rules of engagement with you up front and can exclude anything sensitive.
How often do you test?
As often as you need. Most clients choose a recurring cadence, plus on-demand re-tests after major changes or fixes.
Does this replace a manual pentest?
Not entirely. Continuous testing keeps your infrastructure and web applications covered week to week; expert-led testing goes deep on complex application logic and specific scenarios. Many clients use both.
What do we receive?
Reports after each test, prioritized remediation guidance from our analysts, and evidence you can hand to auditors and insurers.
