Advancing AI Phishing Defense

Adaptive Security develops an AI phishing simulation platform. This platform helps enterprises combat artificial intelligence-based social engineering attacks. It teaches employees to identify and respond to these sophisticated threats.

The platform uses large language models to generate realistic simulated attacks. For instance, it creates emails, text messages, and social media interactions. Adaptive also impersonates executive voices and produces deepfake videos. This trains employees to recognize advanced AI impersonation threats.

AI impersonation threats are rapidly increasing. Recent incidents include AI-generated messages targeting US officials and widespread voice cloning scams. Unlike traditional security awareness providers such as KnowBe4 or Proofpoint, Adaptive focuses specifically on AI-driven deception.
