For organizers

Host Capture The Flag competitions from one control plane.

Create challenges, operate the event, protect integrity, manage access and keep the event history online after the scoreboard closes.

Challenge infrastructure01

Ship challenges, not plumbing.

Create challenge packs, attach files and services, define flags, health checks, hints, prerequisites and dynamic scoring from one control plane.

Live operations02

Run the room in real time.

Watch solves, service health, support incidents, first bloods and scoreboard movement while the event is live.

Branding + registration03

Your event still looks like yours.

Custom identity, landing page, sponsors, ticketing, team rules, invite codes and participant communication without rebuilding the front end.

Integrity layer04

Signals for fair competition.

Submission telemetry, suspicious solve clustering, team-change history, rate limits and review queues designed for organizer oversight.

Payments + access05

Free community CTF or paid finals.

Support open registrations, private cohorts, institution-only events and paid access from the same event model.

Post-event intelligence06

Know what actually happened.

Challenge solve curves, drop-off, difficulty, first-blood timing, participant retention and organizer exports stay attached to the event forever.

For players

Build hacker reputation from every CTF competition.

Results should not disappear when an event ends. CTFWall turns placements, first bloods, category strength and writeups into a portable competitive record.
