Run whitebox AI pentests that prove real exploits against your web app or API.
Shannon fits teams that want pentest findings backed by working exploits instead of theory. That is a real upgrade over noisy scanners. The tradeoff is setup: even the free version asks for source access, a running target, and enough AppSec process to act on what it finds.
AppSec teams running source-aware pentests during release cycles instead of waiting for annual assessments
Skip it if: you only need a fast black-box scan or your team cannot provide source access, a running target, and cleanup time
The OSS tier is strong enough to test the core idea, but the managed platform starts at $50 per developer each month. That is reasonable if validated findings save triage time; it is expensive if your team never operationalizes the workflow.
OSS is free forever, self-run, and uses your own LLM keys.
Pro adds managed platform features, SAST, secrets scanning, dashboard, SSO, and integrations.
Use Shannon on one high-risk internal app first. That shows quickly whether your team can handle the setup, triage, and remediation loop.
Use Shannon when engineering is already exhausted by false positives and you need findings that survive real developer review.
Shannon matters because it closes a specific AppSec gap. Teams ship code continuously, but pentesting still often happens as a yearly event. Shannon tries to bring that proof-backed testing much closer to the release cycle.
