Watch the data that would leak — and harden it first.
Register your org’s surface — staff and donor emails, domains, handles. Perimeter watches for exposure of your assets only, proves every hit with a source and timestamp, and fires a hardening playbook. We never tell you you’re “safe” — only what’s open and how to close it.
Define your surface
Register the selectors that belong to your org. Perimeter watches these — and only these. Signals that aren't on your surface are discarded; nothing is stored.
The honest threat map
The honesty of this map is the point. We name exactly what Perimeter defends, what it routes to an authority, and what no app can touch — and we never overclaim on the bottom rows.
