Redcoat AI is an AI-native security platform designed to protect organizations against social engineering attacks, with a focus on mobile channels. The platform addresses threats amplified by generative AI, including phishing, smishing, and deepfake-based impersonation. The platform operates across three functional areas: Simulate: An on-demand red teaming module called "Pretender" that launches targeted social engineering attack simulations on mobile devices. Scenarios are regularly updated to reflect real-world threats. Assess: An enterprise dashboard that evaluates individual and team-level vulnerability based on simulation results. It provides actionable insights and tracks global attack trends to help identify weak spots. Defend: A mobile defense application called "Defender" that provides real-time protection across personal and enterprise communication channels. It uses an intent-based detection engine designed to block attacks even when message semantics or tactics change. The platform is built by a founding team with backgrounds at Proofpoint, VMware, Prove, and UnifyID, and is backed by multiple venture capital firms including Pear VC.
