The Cost of Scanning and Fixing OWASP Top 10 Security Vulnerabilities in Custom Software

Introduction

The cost of closing a security vulnerability is negligible next to the cost of an attack that exploits it. Understanding this cost balance is the strongest way to justify security investments.

Security Cost vs. Breach Cost

The cost of closing a security vulnerability in advance is a small fraction of the cost of an attack that exploits it. According to IBM’s 2023 report, the average data breach cost is 4.45 million USD. By contrast, the cost of an annual security audit is usually in the 10,000–50,000 USD band.

OWASP Security Services and Their Costs

Typical cost ranges for security services: an annual dependency audit (automated tool): 0–500 USD/year. A SAST scan (SonarQube): 5,000–20,000 USD/year license. A penetration test (manual + automation): 10,000–50,000 USD/year. A Bug Bounty program: variable, but the most valuable for real security vulnerabilities.

Security ROI Calculation

• Annual security investment: 20,000 USD
• Average breach cost avoided: 4,450,000 USD
• Probability of a breach: 5%/year (varies by sector)
• Expected loss reduction: 4,450,000 × 5% = 222,500 USD/year
• ROI: (222,500 − 20,000) / 20,000 = 1,012%
