NexGuards is an AI-powered human-layer security platform built to help organizations defend against modern social engineering attacks. Founded by cybersecurity engineers with experience in offensive and defensive security, NexGuards focuses on securing the most targeted attack surface today - employees. The platform simulates highly realistic phishing, smishing, and vishing attacks using OSINT and generative AI. Unlike traditional solutions that rely on generic templates, NexGuards creates personalized attack scenarios in seconds, closely mirroring how real attackers operate. This allows organizations to uncover true vulnerabilities in employee behavior across departments and roles. When users interact with a simulated attack, NexGuards delivers instant, tailored microlearning to help them understand what they missed and how to respond in the future. Combined with detailed analytics and behavioral insights, NexGuards enables security teams to measure, understand, and reduce human risk in a practical and scalable way.
