Alt Security

Alt Security is a cybersecurity company that offers an agentic offensive security testing platform. The platform is designed to simulate the behavior of an expert penetration tester by learning each target application from the outside in, then identifying business logic flaws and complex attack chains that generic automated testing tools typically cannot detect. The core product is described as an "agentic attacker" — an AI-driven system that autonomously conducts targeted offensive security assessments against web applications and other digital assets. Unlike traditional vulnerability scanners that rely on known signatures or generic test cases, Alt Security's approach focuses on understanding the unique structure and logic of each application to uncover deeper, context-specific vulnerabilities. The company positions its technology for organizations seeking more thorough security testing than conventional automated tools or periodic manual penetration tests can provide. The platform targets business logic vulnerabilities and multi-step attack chains, which are categories of security weaknesses that require contextual reasoning to identify. Alt Security's offering falls within the offensive security and application security testing space, leveraging AI-driven automation to replicate the methodology of skilled human penetration testers at scale.
