Penetration Testing for Startups — Free to Start
Enterprise-grade web application security testing without the enterprise budget. Start free, validate critical flows from the UI, and get HTTP proof for every confirmed finding. No security team required.
Free plan available · No credit card · DNS verification proves you own the target before any test runs
Why startups need web application security testing
Enterprise security budgets don't apply. But the attack surface, the investor due diligence questions, and the compliance requirements do.
No €10k pentest budget required
Traditional penetration testing costs €4,000–€25,000+ per engagement. Free and low-cost automated testing gives startups the same OWASP Top 10 coverage without the spend.
Results before your next investor call
A full automated security test completes in 3–15 minutes. Not weeks. Know your security posture before a due diligence request arrives.
No security team needed
The platform runs independently. Add your target, confirm authorization, configure scope, and launch. No dedicated security engineer required to interpret results.
HTTP proof — not a checklist
Every confirmed finding includes the exact request and response proving impact. You can show evidence to investors, customers, and auditors — not just a scan summary.
Compliance groundwork
SOC 2, ISO 27001, and GDPR auditors require evidence of active security testing. Nautillo Pro generates that evidence — findings mapped to framework controls, with HTTP proof. The formal audit still requires qualified professionals.
Customer trust
B2B prospects increasingly ask about security before signing. A current pentest report — even automated — demonstrates that security is part of your process.
