Only Strix and Shannon both read your source and prove exploits against a running app

Asked:

“web app whitebox pentest scanners for coding ai agents.”

Eight security tools compared across six capabilities — source analysis, dynamic web and API testing, live exploit validation, dependency/secrets coverage, and agent-native interfaces (MCP or agent skills). Each product is backed by its own primary source, 8 URLs across 6 independent hosts, checked 2026-09-14. Blank availability cells were not stated on the fetched pages and are left blank, not guessed.

Capability matrix, grouped by what each tool truly is

capability stated on the tool’s own page not stated Hover or tap a row for the exact wording. A source-aware pentester needs both the source column and the exploit-validation column filled — SAST plus DAST side by side is not the same thing.

What the matrix cannot say

Strix is the most agent-native end-to-end option: MCP, agent skills, CLI, API, CI/CD and Docker, open source under Apache 2.0 with a commercial platform — github.com

Shannon uses source analysis to plan realistic attack paths, then validates exploits live; CLI, API, Docker and SARIF output, AGPL-3.0 open source with commercial licensing — github.com

Agentic StackHawk leans on the coding agent’s own knowledge of the app to steer DAST via MCP and agent skills, but does not itself claim exploit validation or source analysis — docs.stackhawk.com

Burp Suite DAST is automated dynamic testing, but its fetched overview states no agent-native interface, and ZAP’s automation framework is CLI/API/Docker rather than MCP — portswigger.net

Recommended stack

Most agent-native, end to end

Strix: MCP and agent skills plus CLI, API, CI/CD and Docker, with source-aware dynamic testing and exploit validation in one open-source agent.

Source-guided exploit validation

Shannon: source-planned attacks validated against a running target, with SARIF-centric automation for pipelines.

Composable controls

Pair Semgrep Guardian or CodeInspectus (source, dependencies, secrets) with StackHawk or ZAP for the dynamic side when teams prefer separate layers.

Before you point anything at a target

Active scanners execute real attacks: they can alter data or damage vulnerable systems. Run them only against isolated staging targets you own or have explicit written permission to test — never production unless the owner accepts the risk. Shannon, Strix and Burp all state this on their own pages.

Comparison of 8 web-security products for AI coding agents, one row per product; capability marks reflect only what each tool’s own primary page states, fetched and checked 2026-09-14 (8 URLs, 6 independent hosts, no URL backing more than one row). Blank cells mean the page did not state the fact. Safety notes shortened for space; full wording on the linked pages.
