This is mostly intended for people getting started in security. There are so many resources, communities, and paths you can take, and it’s easy to get overwhelmed. Everything below has helped me or someone I know, and I’d trust it to help you too.

RSS Feeds

While I previously maintained my own lists, awesome_threat_intel_blogs does a far better job, which is also available as a Google Sheet.

X Lists

The following are lists which are strictly curated to improve signal:noise ratio. It’s advised that you supplement these with a set of muted words that further filter out unwanted content.

Fundamentals

Newcomers to the industry, or those wanting to deepen their intelligence skills, may also find Curated Intel’s CTI Fundamentals repository useful. It offers an extensive list of blog posts, whitepapers and presentations to help guide and support your learning.

Managing It All

RSS.app can turn X lists into RSS feeds, which can then be pulled into the likes of Feedly or Inoreader alongside your other RSS feeds, Telegram channels, subreddits and Google News searches. For threat intel specific functions, consider Obstracts or Feedly.
