Breach Protocol

Breach Protocol is a free cybersecurity strategy game you play in your browser. Pick a side and the table turns into a fast, replayable tower-defense.

🔵 BLUE TEAM (defend): Waves of cyber-attacks — malware, DDoS, phishing, SQL injection, ransomware, zero-days, and APT bosses — race toward your network core. Deploy the right defense for each threat; every defense is 3× against its matching attack, so reading the wave and mixing your layout is the whole game.

🔴 RED HAT (attack): Flip sides and play the hacker. Spend intel to launch the attacks the enemy can't counter, breach their core, and stay under 100% Trace before the blue team locates you.
