150+ New Sherlocks coming to HTB Labs

We are bringing 150+ investigation scenarios from the LetsDefend platform directly to HTB Labs. We are releasing them as 16 new retired Sherlocks every week from the end of August 2026 until October 15th. Each batch of Sherlocks will be free to play for a full month following its release date.

This gives blue teamers and defenders a steady stream of fresh, real-world analytical scenarios to investigate and solve.
