Operation Red Horizon

Join Team Phoenix cyber task force and investigate a coordinated cyber campaign threatening critical infrastructure in HTB Enterprise Season 1.

The first enterprise season is here

From standalone training to a connected mission.

For years, HTB Enterprise has delivered exclusive Machines, Sherlocks, and Challenges every month. With Enterprise Seasons, those same hands-on scenarios are now connected through a single, evolving story.

Each week unlocks a new scenario, giving every learner a shared narrative while preserving the individual, hands-on experience.
 
Over the next three months, you'll uncover Arodor's proxy network through weekly Challenges, Sherlocks and Machines… all connected by one evolving mission.

 

 

HTB Enterprise vs. HTB Labs Seasons

Enterprise Seasons borrow the concept of Seasons, but not the purpose. Instead of competing on leaderboards, learners progress through a shared mission designed to encourage cross-functional engagement and build organizational readiness.

    Frequently Asked Questions (FAQ)

    Will there still be exclusive content releases on HTB Enterprise Platform?

    Instead of releasing monthly exclusive Machines, Sherlocks, and Challenges, we are introducing Seasons. Still exclusive to organizations but wrapped around a story.

    The goal is to help your team increase engagement by discussing scenarios, comparing findings, and building cross-functional awareness.



    How is it different from HTB Labs Seasons?

    Lab Seasons are built around individual completion and leaderboards. Enterprise seasons are built around organization readiness. The focus isn’t on competing against each other but on preparing teams to respond to modern, cross-domain threats.

    Do I need a separate subscription for this?

    No, this is regularly released scenarios for all organizations on HTB Enterprise.

    How often are scenarios released?

    We release 3 scenarios a month. We publish them on a weekly basis excluding the first week of each month.

    Can I explore content independently, or must an admin assign it?

    Yes, you can. Either your admin will assign the released scenarios to a space, or you can access the announced scenarios of Operation Red Horizon through the HTB Enterprise Content Library.
