Registration is now open for
HTB GCSB 2026,
our free global Capture The Flag competition for business teams.
Running from
May 15–20, 2026,
the event gives your organization a practical way to benchmark your readiness through a thrilling hands-on competition, and compete for
prizes worth up to $38,000 and a secret HTB trophy.
Built for teams of 1 up to 30 players, you will take on
50+ technical challenges

This year’s storyline,
Project Nightfall,
places you inside a nation-state cyber warfare simulation focused on shared dependencies, critical infrastructure, virtualization stacks, identity providers, and supplier ecosystems. Your mission is to work to preserve national resilience against covert interference.
Along the way, you can measure performance against 1,000+ corporate squads worldwide, identify skill gaps across 12 critical domains, and use objective results to support future upskilling and planning within your organization.
The event also includes live hacking workshops on May 14, plus certification-aligned milestones such as
6 CPE credits
for teams reaching 15,000 points and a
Certificate of Completion
for every player who earns at least 200 points.
