About HeimWall

Signal, not surveillance. See how your engineers use Cursor, Claude Code, and Copilot: catch leaked secrets, PII, and confidential data, without blocking them or reading their prompts. Nothing sits in your send path, your prompt reaches the tool untouched, and what you type into an AI tool is never sent to us. To read your prompt before it is sent, the app reads the composer through the macOS Accessibility API and watches the clipboard. Accessibility is a wide permission and macOS does not offer a narrower one for this.

About Tenure

Asking models to follow fragile system prompts is a losing battle. Tenure gives every chat client, IDE, and agent access to institutional knowledge, turns observed agent behavior into policy, enforcing not just what's allowed, but what must be true before it happens. They are blind to whether the agent's actual intent is safe, authorized, or completely rogue. It does not stop a customer-support bot from calling an internal deletion API. An agent may have CRM access without being allowed to update every customer in every situation.
