The document discusses the complexity of penetration testing and whether it is worth the cost. It notes that while some experts see penetration testing as essential, others see it as a waste of money. The reality is more nuanced. Penetration testing can take many forms with varying costs and methods used. A key problem is that penetration tests produce detailed reports of vulnerabilities but organizations often do not have the budget to fix them all, potentially creating legal issues if a breach occurs. However, penetration testing can be useful when focused on the most critical and common vulnerabilities to assess security and persuade management to increase spending. The overall message is that penetration testing is only worthwhile if vulnerabilities found are actually fixed.
