TL;DR
Skipping security scans costs 10-100x more than catching issues early. A vulnerability found in development costs $100-500 to fix. The same issue found after deployment costs $5,000-20,000. Found after a breach? $50,000-500,000+. Free scanning tools exist and catch 60-80% of common issues. The ROI on even basic scanning is essentially infinite.

The Cost Escalation Problem
Security issues follow an exponential cost curve. The later you find a problem, the more expensive it becomes to fix:
| When Found | Cost to Fix | Time Impact |
|---|---|---|
| During development (IDE/local) | $100 - $500 | Minutes to hours |
| In CI/CD pipeline | $200 - $1,000 | Hours |
| In staging/QA | $500 - $2,000 | Hours to days |
| After deployment (no exploit) | $2,000 - $10,000 | Days |
| During active exploitation | $10,000 - $50,000 | Days to weeks |
| After data breach | $50,000 - $500,000+ | Weeks to months |
Why Costs Multiply
Development Phase Fix
When you find an issue while coding, you fix it immediately. One developer, a few minutes, done. Total cost: essentially just salary time.
Production Fix
After deployment, fixing requires:
- Triaging and confirming the issue
- Creating a hotfix branch
- Testing the fix thoroughly
- Coordinating emergency deployment
- Monitoring for regressions
- Potentially rolling back if issues arise
Post-Breach Fix
After a breach, you also need:
- Incident response team (internal or hired)
- Legal counsel for liability assessment
- Customer notification process
- Credit monitoring services for affected users
- PR and customer communication
- Comprehensive security audit
- Regulatory compliance documentation
Real example: A startup found an SQL injection vulnerability during a security scan 3 weeks after launch. Fix cost: $3,000 in consultant time. If they had scanned before launch, fix cost would have been $200 in developer time. If the vulnerability had been exploited first, estimated cost: $75,000+.
What Security Scans Catch
Even basic, free security scans catch the most expensive vulnerabilities:
| Vulnerability Type | Caught by Free Scans? | Potential Cost if Missed |
|---|---|---|
| Exposed API keys | Yes | $500 - $100,000+ |
| Missing database security (RLS) | Yes | $50,000 - $500,000 |
| Vulnerable dependencies | Yes | $10,000 - $100,000 |
| Basic XSS vulnerabilities | Yes | $5,000 - $50,000 |
| Security header issues | Yes | $2,000 - $20,000 |
| SQL injection (basic patterns) | Yes | $50,000 - $500,000 |
ROI calculation: Free scans that take 5 minutes can prevent $50,000-500,000 in breach costs. Even if scans only prevent one incident per year, the ROI is essentially infinite.
Why Startups Skip Scanning
Despite the clear ROI, many startups skip security scanning:
- "We're too small to be a target" - Bots attack everyone; they do not check your company size
- "We'll add security later" - Later never comes, and retrofit costs more
- "It will slow us down" - A 5-minute scan does not slow you down; a breach stops you completely
- "We can't afford security tools" - Free tools exist and catch most issues
- "Our code is too new to have vulnerabilities" - AI-generated code has more vulnerabilities, not fewer
Free Security Scanning Options
| Tool Type | Cost | What It Catches |
|---|---|---|
| GitHub Secret Scanning | Free | Exposed API keys, credentials |
| Dependabot (GitHub) | Free | Vulnerable dependencies |
| npm audit | Free | JavaScript package vulnerabilities |
| CheckYourVibe Free Tier | Free | Vibe coding specific issues |
| OWASP ZAP | Free | Web application vulnerabilities |
| Snyk Free Tier | Free | Dependencies, some code issues |
The Minimum Viable Security Scan
If you do nothing else, do this:
- Enable GitHub secret scanning - Takes 2 minutes, prevents API key leaks
- Run npm audit or equivalent - Takes 30 seconds, finds vulnerable packages
- Scan before launch - Take 10 minutes to run a basic security scan before going live
Total time investment: 15 minutes. Potential savings: $50,000+.
How much does it cost to skip security scanning?
Not scanning typically costs 10-100x more than finding and fixing issues early. A vulnerability found in development costs $100-500 to fix. The same vulnerability found after a breach costs $10,000-100,000+ including incident response, legal fees, and customer notification.
Are free security scanners effective?
Yes, free security scanners catch 60-80% of common vulnerabilities. They are particularly effective for API key exposure, basic misconfigurations, and dependency vulnerabilities. Paid tools add deeper analysis, compliance reporting, and lower false positives.
How often should startups run security scans?
Startups should run automated scans on every code push (via CI/CD integration), weekly comprehensive scans, and monthly manual reviews. At minimum, scan before every deployment to production.
Do I need paid security tools as a startup?
Not initially. Free tools handle most common vulnerabilities. Consider paid tools when you have compliance requirements (SOC 2, HIPAA), need detailed reporting for investors, or want lower false positive rates. Most startups should start with free tools and upgrade as they grow.
