TL;DR
LLMs won’t replace AppSec.
They will dramatically compress the search space.
If you use them right:
- Run multi-model analysis (Opus + GPT + Gemini)
- Structure prompts around attack surfaces, not “find bugs”
- Require PoCs or tests for validation
- Trust only cross-model consensus or reproducible exploits
If you don’t do this, you’ll drown in false positives.
Security research has always been asymmetric.
Attackers need one bug; defenders need zero.
Historically, scale worked against defenders.
LLMs start to rebalance that—not by magically finding zero-days, but by acting as a fast, always-on analyst that can:
- Read entire subsystems in seconds
- Connect logic across files
- Generate realistic attack paths
Used correctly, they don’t replace expertise—they let you spend it where it matters.
Used incorrectly, they produce confident nonsense.
This is a practitioner’s workflow that actually works.
