It engineered the world's largest, most aggressive simulated phishing platform. It is the absolute weapon of choice for rigorous CISOs who mathematically demand a massive, highly automated engine capable of relentlessly phishing their own 10,000 employees every single week until their mathematical susceptibility rate drops to zero.
