Kali Purple is an edition of Kali Linux focused on defensive security, SOC training, monitoring and incident response. It shares the Kali ecosystem while targeting blue and purple team workflows. The official Purple installer is distinct from the standard Kali installer. Plan memory and storage around the defensive services you deploy; installing this image alone does not configure a complete production SOC.
