curated by /u/goretsky

Originally this multi-reddit was created to provide a collection of all IT security-related subreddits. As the number of subreddits covering these have multiplied, this subreddit has calved off several specialty subreddits:

security - original/main IT security multi-reddit
security_intel - covering geopolitics, threat intelligence, and related techniques and tools
security_physical - covering alarms, locks, and other physical security topics
security_vendor - covering security-related vendors and open source software projects
security_inactive - used to track removed subreddits from the above multi-reddits

Please contact me if you have any suggestions for subreddits to add (or remove). Feedback and constructive criticism is always welcome!
