I've been reading up on the concept of joint cyber defense collaboratives and am curious about how these partnerships function in practice. How do different organizations, especially from private and public sectors, collaborate effectively in these setups? What are some of the successes and challenges they've faced in real-world scenarios? Also, what protocols or frameworks are generally followed to ensure that sensitive information is shared responsibly? Looking forward to hearing thoughts or experiences from those who've been a part of or studied these collaborations.
