CTIChef.com Detection Feeds

Teams operating lean security operations centers with limited threat intelligence budgets should start with CTIChef Detection Feeds; the tiered pricing model lets you consume only the detection rules your analysts actually need rather than overpaying for enterprise feeds. The three-tier structure, anchored by the free New Detection Rules Feed, maps directly to NIST DE.CM and DE.AE functions, meaning you get immediate detection rule coverage without backend processing overhead. Skip this if your organization needs finished intelligence products with attribution and strategic context; CTIChef is detection rules first, analysis second.
