Spend Efficiency Curve: LLM-Driven DevSecOps Budget Optimization

Mon., 1. December 2025 | 5 min read

Overview

DevSecOps + LLM tools absolutely can compress security feedback loops, but they sit on top of already-tight security and IT budgets. Industry data shows security averages ~10% of IT spend, with application security a growing slice of that, but budgets are not infinite. For most organizations, LLM-augmented DevSecOps should land around 0.6–1.0% of the total IT budget, with clear diminishing returns beyond ~1.5%. The biggest risk right now is tool sprawl and skills dilution. Your goal should be to buy down risk and lead time, not to “AI everything” in your security infrastructure.
