Veracode’s 2026 State of Software Security report paints a sobering picture. Security debt now affects 82% of organisations. Critical debt affects 60%. High-risk vulnerabilities have risen by 36%. These are no longer engineering metrics alone; they are board-level risk indicators.
Security debt is the accumulation of unremediated vulnerabilities, misconfigurations and architectural weaknesses. Unlike feature debt, it does not always slow delivery in ways the business notices immediately. But it compounds silently until an incident makes the cost visible. The Veracode data suggests that moment is arriving for many organisations.
Why security debt is rising
Several forces are converging. Code is produced faster with AI assistance, but review and remediation have not always kept pace. Supply chains have grown more complex, increasing the number of dependencies with latent vulnerabilities. Security teams remain understaffed relative to the codebases they are asked to protect.
The result is a widening gap between discovery and fix. Scanning tools find more issues than teams can process, and backlogs grow. Without a prioritisation framework, every vulnerability becomes a priority, which means none of them are.
From backlog to risk register
The first step in addressing security debt is to stop treating it as a purely technical backlog. It belongs on the risk register, with clear ownership, likelihood and impact assessments. This reframing helps non-technical leaders understand why remediation resources are needed and why deferral is not free.
Critical debt should be addressed first, but criticality should be business-weighted, not just CVSS-weighted. A vulnerability in an internal admin tool may score highly on a severity scale while posing limited business risk. A lower-scoring issue in a customer-facing payment flow may be more urgent.
A practical remediation playbook
Inventory the debt. You cannot remediate what you cannot see. Build a unified view of vulnerabilities across application scanning, infrastructure scanning, dependency scanning and penetration-test findings. Deduplicate and assign ownership.
Apply risk-based prioritisation. Use exploitability, asset exposure, data sensitivity and business impact to rank issues. Fix what matters first. Accept or time-box deliberate risk where the cost of remediation exceeds the expected loss.
Set a sustainable fix rate. A backlog is a loan with compound interest. Define a weekly or monthly remediation capacity and protect it. A small, consistent fix rate beats an occasional heroic push.
Reduce new debt entering the system. Shift scanning left, block high-risk dependencies at build time and require security review for architectural changes. The fastest way to reduce debt is to stop adding to it.
Measure and report. Track mean time to remediate, backlog age, critical-debt trend and percentage of new findings fixed within SLA. Report these to leadership in business terms.
The board conversation
Boards increasingly want to understand cyber risk in financial and operational terms. Security debt fits that conversation well. It can be expressed as unaddressed exposure, remediation cost, incident likelihood and potential business impact. Translating technical findings into this language is a skill security leaders need to develop.
The Veracode report is a useful prompt: if 82% of organisations carry security debt, the competitive advantage may go to the minority that manage it down systematically.
