CTO and VP Engineering

Deployed in 1-3 days. Zero developer friction. No infrastructure.

Full visibility into what AI coding tools are doing on developer machines. No server deployment, no cloud account, no integration work, no change to how developers work. A single binary, and you can see your team's exposure on day one.

Skarn is the local-first, no-egress forensic layer for the AI-session surface the inline and cloud tools disclaim: local-disk session content, MCP and tool-call detail, and post-hoc attack-chain reconstruction with a session risk score.

1-3

Days to deploy across a team. No infrastructure change, no IT project

Developer workflow changes required. Works silently alongside existing tools

AI tools covered from one binary: Claude Code, Cursor, GitHub Copilot, Gemini CLI, Codex

SARIF

Native output for GitHub code scanning, Semgrep, and any compatible SIEM, with MITRE ATLAS, OWASP LLM Top 10 2025, and CWE taxonomy tags

Deployment, as simple as it gets

Get the binary for your OS

One file. macOS, Windows, Linux. Intel and ARM. No installer, no dependencies, no admin rights in most cases.

Point it at a developer's machine and run

Skarn reads the session logs AI tools already write to disk. No SDK integration, no proxy, no agent injection.

Read the redacted report

Risk score, incident list, session attribution. Everything masked. Nothing uploaded. Takes minutes on a typical machine.

Roll out via your existing endpoint tooling

Deploy organisation-wide the same way you distribute any other binary. No new infrastructure, no new vendor cloud access.

What your team gets

Capability	Available
Session risk score	Per session
Team aggregate reporting	Per team
CI/CD gate (SARIF)	Pipeline-native
Standards mapping (ATLAS / OWASP-LLM / CWE)	SARIF taxonomies
Real-time tool-call blocking	Pre-execution hook (Claude Code, Cursor, Codex, Copilot)
Air-gap / offline mode	Zero egress default
Developer workflow disruption	None

No telemetry. No vendor cloud dependency. Skarn makes no network connection by default and the scan is fully local. The only optional egress is the Team maintained-feed fetch of signed rule updates, and no secret ever leaves the machine; that egress is optional and stays off in an air-gapped environment. The free tier includes the full local scanner under a registered license, for individuals and organisations alike; the org controls - policy-as-code, org-distributed baselines, tamper-evident audit evidence, the maintained feed, and real-time enforcement - are licensed per developer.
