Security program maturity typically progresses through five levels: Level 1 (Ad-hoc) — no formal testing, reactive to incidents only; Level 2 (Repeatable) — annual penetration testing, basic vulnerability scanning; Level 3 (Defined) — regular testing aligned to risk, documented methodology, remediation tracking; Level 4 (Managed) — continuous testing integrated into development lifecycle, metrics-driven improvement; Level 5 (Optimised) — threat-led testing, red team exercises, security as competitive advantage. Most organisations are between Level 2 and 3. Understanding your current level helps prioritise investment and set realistic improvement timelines.
