A three-stage pipeline from raw RSS to ranked intel.

Every hour, BrieflySec pulls from 90+ vetted security sources, scores each story against your interests, and delivers what matters — nothing else.

01// INGEST
Pull every feed, every hour.
90+ RSS, blog, and vendor advisory sources — from MSRC to Project Zero to Mandiant to indie researcher feeds. Dedup at ingest time across sources.

03// SURFACE
Tier-1 alerts first, noise last.
A unified feed — sharply-colored by severity tier. Bookmark, dismiss, or tune; your feedback re-trains the ranker each cycle.

// Platform

Built for analysts who can't read every blog. So we do.

Six things BrieflySec does — every hour, in the background, while you do your job.

// PERSONALIZED
Ranked for you, not the crowd.
Your sector, stack, and skill level shape every score. The same OpenSSH CVE that's Tier-1 for a SOC analyst is noise for a frontend engineer.

// AI SUMMARY
Persona-tuned summary on every story.
Skip 800-word blog posts. BrieflySec writes a TL;DR and technical analysis matched to your role and stack — in fifteen seconds.

// SIGNAL FILTER
Severity tiers, sharply drawn.
Tier-1, High-Priority, Active Threat, Maintenance. Color-coded card bars make the urgency parse pre-attentively.

// COVERAGE
90+ sources, deduplicated at ingest.
Every major vendor advisory feed, every reputable researcher blog, every CISA bulletin — pulled, parsed, and cross-referenced.

// FEEDBACK LOOP
Thumbs up, thumbs down, and we listen.
Every rating retrains your personal ranker. Within a week, your feed reflects what you actually care about — not what's trending on Twitter.

// METRICS
Stats, streaks, score distribution.
See what you've read, what you've dismissed, and how your feed's signal-score distribution shifts as your tuning improves. The ranker is observable, not a black box.

// FAQ

Common questions.

An RSS reader gives you a flat chronological list of every story from every feed — you still have to read it all. BrieflySec ingests the same feeds but scores each story against your stack and role, surfaces TL;DRs, and shows only what's actually relevant to you. Less reading, more signal.
A combination of LLM-based content classification, your explicit tuning (sectors, stacks, role), and online learning from your thumbs-up/down history. Every rating you make retrains your personal model — usually within a week of moderate use, your feed reflects your real interests.
At ingest, every story is fingerprinted by canonical URL, then by content shingles, and then cross-referenced via shared CVE IDs. When sources cover the same story, we merge them into a single card with the primary source and a '+N sources' indicator.
Yes — BrieflySec is a PWA and a native-wrapped iOS/Android app via Capacitor. Same feed, same ranking, on any device.
Your ratings and tuning are scoped to your account and used only to train your personal ranker — never aggregated or shared. We retain bookmarks indefinitely and feed history per your plan.
