Cybersecurity tower defence

Hostile traffic is already on the wire.

Place firewalls, intrusion detection, encryption fields and AI sentinels along the network path. Every threat behaves like the real thing: ransomware is armoured, rootkits are invisible until something detects them, and a zero-day does not care about your rule sets.

Missions

Home Network

A flat consumer LAN behind a single router. One ingress point, one path, no surprises. Learn the controls here.

Lanes: 1
Waves: 20
Best: —

CAMPAIGN ENDLESS

Corporate LAN

Two access floors feeding one distribution switch. Traffic converges in the middle, so the choke point is obvious. Defending it is not.

Lanes: 2
Waves: 25
Best: —

CAMPAIGN ENDLESS

Cloud Region

Two availability zones, two independent ingress paths, one shared egress. You cannot cover both with one battery. Split your budget.

Lanes: 2
Waves: 30
Best: —

CAMPAIGN ENDLESS

Industrial SCADA

A flat OT network with a serpentine route to the historian. The path is long, which buys you time, and every segment is a place you failed to segment.

Lanes: 1
Waves: 30
Best: —

CAMPAIGN ENDLESS

Datacenter Core

Three ingress trunks converging on the crown jewels. Everything the adversary has, arriving at once, from three directions.

Lanes: 3
Waves: 35
Best: —

CAMPAIGN ENDLESS

Remote Workforce

Four ingress points and one concentrator. Everyone dialled in from somewhere else, and all of it funnels through the same tunnel before it touches anything that matters.

Lanes: 4
Waves: 25
Best: —

CAMPAIGN ENDLESS

Container Cluster

Short paths, wide open floor, and workloads that appear and vanish faster than anyone can inventory them. Nothing here takes long to reach the middle.

Lanes: 3
Waves: 30
Best: —

CAMPAIGN ENDLESS

Supply Chain

One route in from the internet, and one from a vendor you already trust. The second does not pass your perimeter because it was never meant to.

Lanes: 2
Waves: 30
Best: —

CAMPAIGN ENDLESS

Air-Gapped Facility

Isolated, in theory. The route in is long and there is almost nowhere to stand: this floor was built for equipment, not for defenders.

Lanes: 1
Waves: 35

MITRE ATT&CK Adventure

Every threat in CyberTowers is a real ATT&CK technique and every defence a real D3FEND countermeasure, drawn from the same dataset. Play the other side of the board: walk the kill chain as the attacker, or deploy countermeasures as the defender.
