Building an Offline AI Security Scanner That Doesn't Hallucinate Findings

How AiSec Studio pipes every scan through parser → rule engine → knowledge graph before a local LLM ever sees it — and why that order matters. 60-second Auto Scan demo included.

Most "AI-powered" security scanners work the same way under the hood: grab the target's code or HTTP responses, stuff them into an LLM prompt, and ask it to find vulnerabilities. It demos well. It also hallucinates constantly — the model pattern-matches on plausible-looking code and reports things that were never exploitable, or never there at all.

I've been building AiSec Studio, an offline AI security research platform, around the opposite assumption: the LLM should never be the thing that discovers a vulnerability. It should only reason over what a deterministic system already found.

Here's a 60-second walkthrough of the Auto Scan lane — target URL in, reviewed report out — followed by how the pipeline behind it is actually built.
