Articles about threat intelligence from security operations practitioners.
Open-source threat intelligence is worth using when it produces measurable incremental value. It's noise when it adds stale, duplicated, low-confidence indicators that raise alert volume without changing an outcome. Here's the six-measure test I run before renewing, adding, or automating any feed.
Renewal prep, last quarter: four feed subscriptions, six figures across the set. I ran the test I run on every vendor line and named one decision each feed changed in ninety days. Two cleared the bar; I cut the other two.
Dark web monitoring sounds like one capability but bundles three: credential monitoring, forum crawling, and actor tracking, each sourced and operated differently. Buyers conflate them, then discover they bought a credential feed when they expected adversary context.
Most CTI programs quietly collapse into IOC feed management with a weekly report attached, running one of the role's three horizons and calling it the whole function. Scope the analyst across tactical, operational, and strategic work, and judge it on whether it changes a detection or a decision inside the SOC.
Most threat intelligence never reaches a detection rule. The cause is structural: a format mismatch between TI delivery and detection workflows.
Practitioner takes on SOC modernization, detection engineering, threat hunting, and more. No fluff. No product pitches.
