TL;DR: Security debt now affects 82% of organisations and 60% carry critical debt, according to Veracode’s 2026 State of Software Security report, showing that unresolved vulnerabilities have become a persistent business risk rather than a back-office hygiene issue. Treating security debt as a board-level KPI changes prioritisation, accountability, and remediation investment.
NHIMG editorial — based on content published by Veracode: Why Security Debt Should Be a Board-Level Priority
By the numbers:
- 82% of organizations are now burdened by security debt, an 11% increase from the previous year.
- 60% of organizations carry critical security debt, flaws that are both severe and highly exploitable.
- The 2026 State of Software Security report identified a 36% relative increase in high-risk vulnerabilities.
Questions worth separating out
Q: What makes security debt different from ordinary vulnerability backlog?
A: Security debt refers to known vulnerabilities that remain unresolved long enough to become persistent exposure, usually a year or more.
Q: When should organisations prioritise security debt over new feature delivery?
A: Organisations should prioritise security debt whenever unresolved flaws are both severe and highly exploitable, or when they sit in systems that support sensitive data, authentication, or privileged operations.
Q: What signals show that security debt is becoming unmanageable?
A: The clearest signals are rising counts of aged vulnerabilities, repeated appearance of the same flaw categories, and remediation queues that do not shrink quarter over quarter.
Practitioner guidance
- Define security debt as a governed risk class Separate vulnerabilities older than 12 months from routine backlog items and track them with explicit ownership, age thresholds, and escalation criteria.
- Prioritise by exploitability and business criticality Rank unresolved flaws by severity, ease of exploitation, and whether they affect crown-jewel applications or privileged access paths.
- Make remediation capacity a board discussion Report quarterly on debt trends, average age of unresolved issues, and the volume of high-risk items that exceed SLA targets.

Security debt becomes a control failure when it is treated as a backlog item rather than a risk exposure. The article is right to reframe unresolved vulnerabilities as a board concern, because aging defects behave like standing exposure, not ordinary technical housekeeping. That makes this a governance issue across software, IAM, and NHI programmes whenever known weaknesses are left open long enough to become predictable entry points. Practitioners should manage aged exposure as a liability with ownership, deadlines, and risk-based escalation.
A question worth separating out:
Q: Who should be accountable for security debt reduction?
A: Accountability should sit with executive leadership and the engineering owners who control remediation capacity. Security can prioritise and measure, but the business must decide how much delivery capacity is reserved for reducing risk. Without that shared ownership, debt becomes a recurring operational tax instead of a managed risk.
