CISO's First 100 Days: Using Penetration Testing to Establish Your Baseline — 日本企業向けガイド

When a new CISO joins an organisation, they need an objective assessment of the current security posture — not the version described in policy documents, but the reality on the ground. A penetration test in the first 100 days provides: an independent, evidence-based view of actual vulnerabilities, a comparison against industry benchmarks, identification of the most critical risks requiring immediate attention, and a baseline against which future improvements can be measured. This evidence-based starting point is invaluable for building a credible security program and securing budget for necessary improvements.
