TL;DR: Security debt now affects 82% of organisations and 60% carry critical debt, while average remediation half-life sits at 243 days and third-party vulnerabilities take 358 days to fix, according to Veracode's 2026 State of Software Security report. The governance failure is not visibility alone, but treating remediation as a technical queue instead of a business risk decision.
NHIMG editorial — based on content published by Veracode: Security Debt Management Requires a Board-Level Conversation: Here’s How to Own It
By the numbers:
- 82% of organizations now carry security debt and 60% carry critical security debt.
- The average fix half-life across all scan types sits at 243 days.
- For third-party and open-source vulnerabilities found through software composition analysis, that half-life extends to 358 days.
Questions worth separating out
Q: How should organisations govern security debt when remediation keeps slipping?
A: They should treat security debt as an enterprise risk with a named owner, board reporting, and explicit remediation targets.
Q: Why does long remediation half-life increase security risk?
A: Because the longer a vulnerability stays open, the more time attackers have to discover and weaponise it.
Q: What do security teams get wrong about security debt reporting?
A: They often report raw vulnerability counts without showing trajectory, severity mix, or how quickly critical items are resolved.
Practitioner guidance
- Tie remediation targets to executive KPIs Set board-visible targets for critical fix half-life, backlog reduction, and third-party exposure so remediation is measured as a business outcome, not a team preference.
- Classify debt by exploitability and business exposure Split findings into critical, elevated, and managed categories, then map each category to a named owner and decision path.
- Reserve remediation capacity in engineering planning Commit a fixed share of sprint capacity to debt reduction, especially for applications carrying the longest tails.

Security debt is a lifecycle failure, not an AppSec metric. When vulnerabilities remain unresolved for a year or more, the organisation is no longer managing defects, it is managing exposure persistence. That changes the governance question from how many findings exist to who owns the exposure window and what business risk is acceptable. Practitioners should treat prolonged remediation as a control breakdown in risk acceptance and accountability.
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.
