What is a village. Blue Team Village (our friends just call us BTV) is both a place and a community built for and by defenders. It's a place to gather, talk, share, and learn from each other about the latest tools, technologies, and tactics that our community can use to detect attackers and prevent them from achieving their goals. Village FAQs. BTV promises to be an all out firehose of Blue Team learning, sharing, and fun for the defenders that build stuff, defend stuff, and just make it generally hard for attackers. Come celebrate the other side of the hacking mirror with us. We’ll keep a blue light on for you!
