Subreddit guides combine public Reddit source URLs, captured rules, visible verification dates, and Rankhog's account-safety workflow.
This subreddit is for discussing cybersecurity topics, research, and emergent threats and findings. It is a discussion oriented sub for people who are, or aspire to be, cybersecurity professionals. The goal is to have insightful discussions around these topics.
The rules that decide if a marketing adjacent post survives are “Must be relevant to cybersecurity professionals”, “No low effort / poor quality posts”, “No advertising”, “No excessive promotion”, “No personally-identifiable information”, and “Civility”.
A good post here is something that is highly insightful and relevant to professionals. This could be a detailed research finding on a new threat or an educational article that discusses a complex cybersecurity topic. If you are sharing a resource, it must be educational and follow all the advertising guidelines.
You must avoid posting memes, security fails, or homework help because those things generally do not drive conversation. You must also avoid any editorializing or political agendas unless the post is strictly geared towards the security implication. Finally, you must never post personally-identifiable information.
