Why Shift Left Is Dead
DevOps.com, Wednesday, September 23rd, 2026
DevOps.com argues shift-left security can't handle AI-era risks that appear before any code is written.
DevOps.com argues that shift-left security, introduced in 2001 to catch problems early in development, no longer suffices in AI-driven environments, since AI introduces risk 'before a single line of code is generated' through prompts, untrusted agents, and malicious packages.
It cites research showing 100% of companies have AI-generated code yet 81% of security teams lack visibility into how AI is being used.
The article calls for replacing the traditional Software Development Lifecycle with an Agentic Development Lifecycle (ADLC) governing AI tools, models, and data access throughout development.
Required controls include visibility into shadow AI usage, guardrails against malicious packages and secret exposure, and auditable governance records for accountability.
