Fly.io: Pentest vs Automated Scan
Pentests cost $5k-$50k+ and take weeks. For Fly.io apps, automated scanning catches the same vulnerabilities instantly. Here's how to decide.

Pentest vs Automated Scan
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
Fly.io Security Reality
Fly.io applications have predictable security patterns. The most common vulnerabilities—exposed secrets, missing access controls, weak authentication—are well-documented and consistently detected by automated scanners. A pentest will find these same issues, but at a much higher cost.
Common Fly.io Vulnerabilities (Caught by Both)
- Hardcoded API keys and secrets
- Missing database access controls
- Weak authentication configuration
- Missing security headers
- Insecure session management
A $15,000 pentest finds these. VAS finds them in 5 minutes for free.
The Verdict
For most Fly.io 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 Fly.io apps, automated scanning is sufficient.

Get Starter ScanFrequently Asked Questions
How much does a pentest for a Fly.io app cost?
Professional penetration testing typically costs $5,000-$50,000+ depending on scope. For a standard Fly.io 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 Fly.io apps?
For most Fly.io 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 Fly.io app compromises come from basic misconfigurations that automated scans catch.
Should I get a pentest before launching my Fly.io 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 Fly.io 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.
