Why You Should Even Bother With RSS for Security News
I stopped checking cyber news sites directly about five years ago. The browser-tab approach just doesn't scale when you're trying to track threat intel, patch releases, and regulatory updates across multiple feeds. RSS was the first thing that actually worked. It's not glamorous, but it cut my morning information-gathering from about 45 minutes down to maybe ten. The list below is what I actually use. Not everything on every blog post you'll find online. Most of those roundups are populated by people who've never had to triage actual threat alerts at 2 AM. Here's what survives real use. Krebs on Security — Brian Krebs still writes the single most actionable stories about breach infrastructure, payment card fraud, and supply chain compromises. His RSS feed at krebsonsecurity.com/feed/ gets updated roughly daily but every post is worth reading. No clickbait, no fluff.
Roughly Writes (Dave Kennedy) — Covers red team operations, social engineering, and tooling. Feed: roughlywrites.com/feed/. This one's more tactical than strategic. Useful if you're actually running attacks in your own environment for testing. Schneier on Crime — Bruce Schneier's legal and policy angle matters more than most realize. When CISA drops a new advisory or Congress drafts surveillance legislation, he's usually the first person to explain what it actually means for practitioners. Feed: schneier.com/feed. The Hacker News — High volume, mixed quality. The RSS feed filters out most of the SEO spam that shows up on their homepage. Feed: thehackernews.com/feeds/posts/default?alt=rss. Skim fast. Grab anything mentioning a CVE with a CVSS above 7.
CISA Alerts and Advisories — This isn't a blog. It's the official government feed. Slow, dry, and more accurate than anything else you'll find when an active zero-day drops. Feed: cyber.dhs.gov/atom.xml. Subscribe to this first if you only subscribe to one. FOSS Force — Security Section — Underrated. Covers open-source security tooling, vulnerability disclosures in Linux packages, and supply chain issues. Feed: fossforce.com/feed. The security-tagged posts are the ones worth pulling.

How I Actually Set This Up
Most people use Feedly or Inoreader. I use NetNewsWire on Mac because it's local-first and doesn't try to sell you anything. If you want cloud sync across devices, Inoreader's free tier handles about six feeds comfortably before it starts throttling refreshes. That's fine if you're casual. It's not fine if you need real-time alerting. For actual alerting, I route CISA and Krebs through a simple webhook to a Slack channel. It costs about forty cents a month if you count the n8n instance I run for it. The rule is basic: if the title contains "advisory," "exploit," or "CVE," post it. Everything else just sits in the reader. One thing nobody mentions: deduplication matters more than you think. The same CVE gets covered by roughly twelve different outlets within hours of disclosure. Your RSS reader will show you all twelve unless you set up grouping rules. Inoreader does this automatically. NetNewsWire requires a third-party script. I wrote one in Python that hashes the title and body, keeps only the first three variants, and discards the rest. Takes about twenty minutes to set up if you know where to hook it.
What Actually Breaks
The biggest problem I hit was feed rot. Three of the feeds I originally subscribed to stopped updating their RSS endpoints around 2023. The sites themselves were still active but they'd switched to JavaScript-rendered content that no longer emitted proper Atom feeds. You won't know until your reader starts showing stale dates and you wonder why. The workaround: check each feed quarterly. Feedchecker.net will validate them in bulk. Any feed returning a 404 or non-standard MIME type should be replaced immediately. There's almost always an alternative. For the ones that went dark, I found mirror feeds or switched to the author's Substack, which does emit proper RSS automatically. Another issue is volume. The Hacker News alone can push twenty-plus items a day during active incident windows. If you don't filter aggressively, you'll just stop opening the reader altogether. I use tags and unread thresholds. Anything under "critical" gets marked read within an hour unless it has a direct link to a vendor advisory. That habit alone kept me from abandoning the whole system.
When RSS Won't Save You
Real-time exploit kit chatter doesn't show up in RSS feeds. If you need to know about active_campaign infrastructure or newly discovered C2 channels the same day they go live, RSS is the wrong tool. Twitter/X lists and Telegram channels move faster for that. The tradeoff is noise. You get information sooner but you spend considerably more time sorting signal from garbage. If your goal is just staying informed about published vulnerabilities, policy changes, and major breach disclosures, RSS remains the most efficient setup available. It's not the flashiest approach. But it works reliably and it doesn't require you to open a browser and scroll through ads on every news site individually.
