We scanned 1,106 online stores: the platform fixes what the browser sees, not what your customer gets emailed

We passively scanned 1,106 online stores on their own domains and sorted them by platform. Shopify's 341 stores send HSTS and CSP 98.5% of the time — and only 25.8% of them enforce DMARC. A managed platform buys you the half a browser sees, and nothing on the half that reaches your customer's inbox.

Microsoft's July 2026 Patch Tuesday fixed a SharePoint flaw, CVE-2026-56164, that was already under active attack — the third SharePoint vulnerability exploited in about ten days.

One HTTP header could impersonate any user in Gitea's Docker image (CVE-2026-20896)

A high-severity flaw in Gitea's official Docker image — CVE-2026-20896, CVSS 9.8 — let one HTTP header impersonate any user, including an admin.

Researchers documented JADEPUFFER, the first ransomware operation run end-to-end by an AI agent. The headline is the AI. The root cause is ordinary: an app left facing the internet with a known, already-patched flaw and no login required. The fix is the same as it's always been — know what of yours is exposed.
