v0.dev: Pentest vs Automated Scan

Pentests cost $5k-$50k+ and take weeks. For v0.dev apps, automated scanning catches the same vulnerabilities instantly. Here's how to decide.

When You Need a Pentest

  • You're handling highly sensitive data (healthcare, finance)
  • You have regulatory compliance requirements (SOC 2, PCI-DSS)
  • You have complex custom business logic
  • You're about to raise significant funding
  • You need a formal security attestation
  • Your app has been breached and you need forensics

When Automated Scanning Works

  • You're building an MVP or early-stage product
  • You want immediate security feedback
  • You need to scan after every deployment
  • Your budget is limited
  • You're using standard tech stacks (Supabase, Firebase)
  • You want to fix obvious issues before a pentest

v0.dev Security Reality

v0.dev generates UI components that need to be connected to backends. The security issues arise in how developers integrate these components with data sources. Common patterns—insecure data fetching, missing auth checks—are exactly what automated scanners detect.

Common v0.dev Vulnerabilities (Caught by Both)

  • Components fetching data without auth verification
  • Client-side data filtering instead of server-side
  • Form submissions without validation
  • XSS vulnerabilities in dynamic content
  • Insecure API integration patterns

A $15,000 pentest finds these. VAS finds them in 5 minutes for free.

The Verdict

For most v0.dev applications, start with automated scanning. It's free, instant, and catches the vulnerabilities that actually cause breaches. If you have complex business logic, compliance requirements, or handle sensitive data, add a pentest after fixing automated findings.

Run a free VAS scan first. Fix those issues. Then decide if the remaining risk justifies a $10k+ pentest. For 90% of v0.dev apps, automated scanning is sufficient.

Frequently Asked Questions

How much does a pentest for a v0.dev app cost?

Professional penetration testing typically costs $5,000-$50,000+ depending on scope. For a standard v0.dev web application, expect $10,000-$20,000 for a thorough assessment. VAS provides automated scanning that catches the most common vulnerabilities for free.

Can automated scans replace pentests for v0.dev apps?

For most v0.dev applications, automated scanning catches 80%+ of real vulnerabilities at a fraction of the cost. Pentests add value for complex business logic, but the majority of vibe-coded apps have standard vulnerability patterns that automated tools detect perfectly.

What vulnerabilities would a pentest find that VAS wouldn't?

Pentests excel at: complex business logic flaws, chained attack scenarios, social engineering vectors, and novel/zero-day vulnerabilities. However, these represent a small percentage of actual breaches. Most v0.dev app compromises come from basic misconfigurations that automated scans catch.

Should I get a pentest before launching my v0.dev app?

Start with automated scanning (free, instant results). Fix those issues first. If you're handling sensitive data, have compliance requirements, or have complex custom logic, then consider a pentest. For most MVPs and early-stage apps, automated scanning provides sufficient security validation.

How often should I scan vs pentest my v0.dev app?

Scan after every major deployment (VAS makes this easy). Pentest annually if you have the budget, or before major launches/funding rounds. The continuous automated scanning catches regressions; annual pentests provide deep-dive assurance.
