Tenzai is a cybersecurity company that develops an agentic, AI-driven penetration testing platform designed to continuously identify, exploit, and remediate vulnerabilities in enterprise applications. The platform is built around autonomous AI "hackers" that are intended to replicate the offensive reasoning and techniques of skilled human penetration testers, operating at machine speed and scale. The core offering is a SaaS-based (with optional on-premises deployment) penetration testing service that continuously tests enterprise web applications against a user-defined set of authorized targets. The platform handles the full cycle of offensive security: reconnaissance, exploitation, and remediation guidance, without requiring ongoing manual involvement from human testers. Tenzai is currently in private beta, with access available via a proof-of-concept (POC) request process. The POC period runs for 30 days and is offered at no cost. The company was founded by veterans of offensive cybersecurity, with backgrounds including military intelligence units and prior roles at companies such as Guardicore and Snyk. Tenzai, Inc. is incorporated in Delaware, United States, and has raised $75 million in seed funding from investors including Greylock, Battery Ventures, Lux Capital, and Swish Ventures. Key platform characteristics: - Continuous, autonomous penetration testing of enterprise applications - AI agents that operate with adversarial reasoning - Targets defined and authorized by the customer - Available as SaaS or on-premises deployment - Remediation guidance included alongside vulnerability discovery
