id: feed_office365
name: Microsoft 365 Endpoints Feed
version: 1.0.0
description: "Microsoft 365 endpoints feed connector — pull the official published IP ranges and URLs for Microsoft 365 / Office 365 services and emit normalized IOCs (CIDR and domain + type, with service area) for import into the Threat Indicator Manager. Intended as an allowlist / known-infrastructure feed (mark benign in TIM). Free public endpoint, no authentication required; stdlib-only, no extra Python dependencies."
changelog: "1.0.0 — Initial release: fetch the Microsoft 365 worldwide endpoints (IPs + URLs)."
category: feed
# The endpoints.office.com service is free. instance selects the cloud
# (Worldwide, USGovDoD, USGovGCCHigh, China, Germany).
