Helping security engineers and Windows/AD administrators 𝘁𝗮𝗸𝗲 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝗼𝗳 𝗹𝗲𝗴𝗮𝗰𝘆 𝗪𝗶𝗻𝗱𝗼𝘄𝘀 𝗶𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀 — where years of changes, misconfigurations, and hidden permissions create 𝗮𝘁𝘁𝗮𝗰𝗸 𝗽𝗮𝘁𝗵𝘀 𝘄𝗮𝗶𝘁𝗶𝗻𝗴 𝘁𝗼 𝗯𝗲 𝗮𝗯𝘂𝘀𝗲𝗱.

→ 𝗘𝗱𝘂𝗰𝗮𝘁𝗶𝗼𝗻: practical courses that teach how attackers abuse Windows/AD and how to harden it properly

𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝘂𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁: we don’t want security to depend on us long-term. We focus on 𝗹𝗲𝗮𝘃𝗶𝗻𝗴 𝘁𝗵𝗲 𝗸𝗻𝗼𝘄𝗹𝗲𝗱𝗴𝗲 𝗮𝗻𝗱 𝗰𝗮𝗽𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗶𝗻𝘀𝗶𝗱𝗲 𝘆𝗼𝘂𝗿 𝘁𝗲𝗮𝗺, so you can defend your infrastructure even after we’re gone.

This approach is backed by real field work — 𝟯𝟬+ 𝗪𝗶𝗻𝗱𝗼𝘄𝘀/𝗔𝗗 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗮𝘀𝘀𝗲𝘀𝘀𝗺𝗲𝗻𝘁𝘀 in the last 5 years across different types of production environments. Everything we teach and publish is based on what actually breaks, what attackers actually abuse, and what teams can realistically implement.
