Hack The Box Pro Labs are premium, subscription-based training lab environments designed for practicing offensive security and red team techniques against simulated enterprise infrastructures. Each lab scenario is built around Active Directory environments running modern, hardened operating systems, and is created by industry practitioners. Labs are structured around realistic corporate network topologies involving multiple machines, network segments, and interactive users. Lab scenarios are organized into four Red Team Operator skill levels (I–IV), with individual labs varying in difficulty from beginner to advanced. Available labs include Dante, FullHouse, XEN, P.O.O., Hades, and RPG, among others, each with a defined number of machines and flags. Core skill areas covered across labs include: - Active Directory enumeration and exploitation - Lateral movement and network pivoting - Privilege escalation (local and domain) - Web application attacks - Phishing techniques and leveraging interactive users - Password cracking, network sniffing, and disk backup forensics - Blockchain, AI/ML attack techniques (FullHouse lab) A single subscription grants access to all Pro Labs, with the ability to switch between lab scenarios at any time (Lab Rotation feature). Upon completing a lab, users receive a certificate of completion and 40 CPE credits (per full lab; some labs award 10 CPE credits). CPE credits are recognized in conjunction with ISC² certifications. Labs integrate with HTB Academy via the "Academy x HTB Labs" feature, which helps users identify preparatory learning paths before attempting a Pro Lab.
