A founder reached out last month: “We’re pre-revenue, just launched, and a potential customer asked if we’ve had a pentest. Should we get one?”
My answer: probably not yet.
Pentests are valuable. They’re also expensive, time-consuming, and often premature for early-stage startups. Understanding when you need one helps you allocate limited resources effectively.
What a Pentest Actually Is
A quality pentest includes:
- Reconnaissance: Understanding your attack surface
- Vulnerability identification: Finding weaknesses
- Exploitation: Proving vulnerabilities are real
- Business logic testing: Attempting to abuse features
- Report: Detailed findings with remediation
- Retest: Verifying fixes (usually included)
What you’re paying for:
- Human expertise (security researchers)
- Time (typically 1-3 weeks of testing)
- Custom analysis of your specific application
- Report suitable for compliance/enterprise sales
What a Pentest Catches
Pentests excel at finding:
Business Logic Flaws Can a user manipulate the checkout flow to get free items? Can they access another user’s data by changing an ID? Automated scanners miss these; humans find them.
Authentication Bypass Creative ways to circumvent login, from session manipulation to OAuth misconfigurations.
Complex Attack Chains Vulnerabilities that require combining multiple issues. Individually harmless, together catastrophic.
Privilege Escalation Starting as a regular user and finding paths to admin access.
Data Exposure Through Feature Abuse Using legitimate features in unintended ways to access sensitive data.
What a Pentest Doesn’t Catch (Efficiently)
Pentests are expensive for finding:
Missing Security Headers Automated scanners detect this in seconds. Paying a pentester to find missing X-Frame-Options is waste.
Known Dependency Vulnerabilities npm audit is free. A pentest finding an outdated package is not good use of budget.
CORS Misconfigurations
Automated tools catch origin: '*' immediately.
Basic SQL Injection Standard injection patterns are well-covered by automated scanners.
SSL/TLS Issues Certificate problems, weak ciphers, these are scanner territory.
The Decision Framework
You Need a Pentest When:
Raising Series A or Beyond Investors conduct due diligence. A clean pentest report demonstrates security maturity. Budget 2-4 weeks before your raise timeline.
Selling to Enterprise Enterprise buyers require security documentation. A pentest report, especially from a recognized firm, opens doors that self-attestation can’t.
Handling Sensitive Data at Scale Healthcare data, financial data, personal information for thousands of users. The liability profile demands thorough testing.
Required for Compliance PCI-DSS, SOC 2 Type II, HIPAA, some frameworks require penetration testing. Check your compliance requirements.
Post-Breach (or Near-Miss) After a security incident, a pentest identifies what else might be vulnerable. It also demonstrates corrective action to affected parties.
Complex Application Logic Marketplaces, financial applications, platforms with money movement, anywhere business logic complexity creates attack surface.
You Don’t Need a Pentest When:
Pre-Launch or Early Stage Your codebase changes daily. A pentest is a point-in-time assessment. Testing code that will change next week wastes money.
Limited User Data No sensitive data? Limited attack value means limited testing need.
Tight Budget $10k on a pentest vs. $10k on features that get you to revenue? Features first. Security monitoring provides coverage meanwhile.
No Compliance Requirements No enterprise customers asking, no compliance frameworks demanding it, no need to check the box.
Simple CRUD Application A basic SaaS without complex business logic has limited attack surface beyond what automation catches.
The Preparation Strategy
When you do need a pentest, preparation determines value.
Bad Approach:
Commission pentest immediately. Pentesters spend 60% of their time finding basic issues automated tools would catch. Report comes back with 47 findings, 40 of which are “implement security headers.”
Good Approach:
Prepare for a Pentest
Maximize value from your penetration test
Run Automated Scanning First
Document Your Architecture
Create Test Accounts
Define Scope Clearly
Identify High-Value Targets
Schedule Appropriately
A prepared pentest might cost the same but delivers 3x the value. Pentesters find business logic issues instead of missing headers.
The Continuous Monitoring Alternative
For early-stage companies not ready for pentests:
What Continuous Monitoring Provides:
- Ongoing vulnerability detection
- Security header validation
- Configuration monitoring
- Dependency tracking
- Immediate alerting on regressions
What It Doesn’t Provide:
- Business logic testing
- Human creativity in attack vectors
- Compliance-satisfying reports
- Deep authentication testing
The Practical Path:
- Start with continuous monitoring immediately
- Address all automated findings
- Commission pentest when business requirements demand it
- Continue monitoring between pentests
This approach maintains security posture while reserving pentest budget for when it creates business value.
Pentest Cost Factors
Understanding pricing helps budget appropriately:
| Factor | Impact on Cost |
|---|---|
| Application complexity | Higher = more expensive |
| Scope breadth | More systems = more expensive |
| Testing depth | Black box < Gray box < White box |
| Firm reputation | Brand names charge premium |
| Retest inclusion | Usually 10-20% of initial cost |
| Report format | Compliance-ready reports cost more |
| Timeline | Rush jobs cost 50%+ premium |
Budget Ranges:
- Simple web app, small firm: $5,000-$10,000
- Medium complexity, established firm: $15,000-$25,000
- Complex application, top-tier firm: $30,000-$50,000+
- Enterprise with multiple systems: $50,000-$150,000+
After the Pentest
Getting value from results:
Immediate Actions (Week 1):
- Triage critical and high findings
- Assign remediation owners
- Begin fixing critical issues
Short-term (Weeks 2-4):
- Address remaining high and medium findings
- Request retest for critical fixes
- Update security documentation
Ongoing:
- Implement continuous monitoring
- Schedule next pentest (annually or with major changes)
- Track security metrics over time

Conclusion
Key Takeaways
- Pentests cost $5k-$50k and are a point-in-time assessment, not ongoing protection
- Most early-stage startups don’t need pentests until Series A, enterprise sales, or compliance requirements
- 80% of typical pentest findings are catchable by automated scanning at 1% of the cost
- Pentests excel at business logic flaws, authentication bypass, and complex attack chains
- Preparation dramatically increases pentest value: fix automated findings first
- Continuous monitoring maintains security posture between pentests
- Document your architecture and create test accounts before engaging pentesters
- Schedule pentests strategically: before fundraising, not during launch weeks
- Annual pentests plus continuous monitoring provides comprehensive coverage
- The decision framework: sensitive data + enterprise sales + compliance = pentest needed
The security industry profits from fear-based selling. Not everyone needs a $30,000 pentest.
What everyone needs is security appropriate to their stage. For most indie hackers, that’s continuous monitoring now and pentests later, when business requirements, not fear, drive the investment.
Use the framework. Spend security budget where it creates value. A well-timed pentest opens enterprise deals. A premature pentest just finds the missing security headers you could have caught for free.
