Periphery keeps a live map of every third-party you depend on and every AI tool your team quietly signs up for. One dashboard, one score, one story you can tell your board.
Drop in a vendor's URL — Stripe, your CRM, your bank. We start pulling public signals in seconds. No API keys, no integration calls.
Every few hours we re-check certificate transparency logs, DNS, DMARC, breach feeds, and (Pro) shadow-AI usage from the extension.
A single explainable score per vendor, alerts to Slack when it moves, and a PDF report your client or insurer will actually read.
Cert expiry, new subdomains, SPF/DKIM/DMARC gaps, breach mentions — refreshed on autopilot.
A browser extension flags AI tools your team signs up for. Domain + timestamp only. Never content.
Every 0–100 breaks down into the exact signals behind it. No black boxes to defend.
Slack, email, or your own webhook — the second a vendor's posture slips.
One click. A vendor posture report you can hand to an auditor, insurer, or a nervous customer.
Multi-tenant from day one. Run every client's perimeter from a single workspace.
One domain. Sixty seconds. Then decide if it's worth another minute.
