Legit Security has introduced VibeGuard, a breakthrough application security platform designed to secure AI-generated code at the exact moment it is created—ushering in a new era of AI-native protection. Announced in Boston, the solution addresses one of the most urgent challenges in modern development: the rapid rise of AI-generated code and the growing risks tied to AI coding agents.
Unlike traditional AppSec tools that rely on manual review cycles and post-development scanning, VibeGuard embeds security directly into AI-enabled IDEs such as Cursor, Windsurf, and GitHub Copilot. The platform continuously supervises coding agents, blocks attacks, and prevents vulnerabilities before they enter production. It also infuses AI agents with security intelligence, continuously training them to produce safer code.
The urgency behind this innovation is clear. In a recent survey conducted by Legit Security and Gatepoint Research, 56% of security professionals cited limited visibility and control over AI-generated code as their top concern. With vibe coding rapidly becoming the norm and development speed outpacing traditional security checks, organizations face heightened exposure—from prompt injection attacks to accidental data leakage through risky third-party tools.
VibeGuard offers end-to-end protection for both AI-generated code and the agents creating it. It monitors prompts, models, and MCPs; enforces secure coding policies; and blocks unsafe behaviors such as malicious tool use or unintentional exposure of sensitive assets. For AppSec teams, it provides unified oversight across every coding environment, enabling them to apply guardrails and governance with precision.

“We’re at an inflection point in how software is built,” said Roni Fuchs, co-founder and CEO at Legit Security. “Code is no longer written line-by-line by humans – it’s generated by machines. With VibeGuard, we’re not just launching a new product, we’re defining what it means to secure AI-native development. AI is transforming software creation, and for the first time in history, we have a real opportunity to create software that’s truly secure – by design.”
Industry leaders echo this shift. “AI has completely changed the game for application development,” said Nir Yizhak, Chief Information Security Officer and Vice President at Firebolt. “We see AI-powered development as a huge opportunity… I’m excited to see Legit take this big step forward.”
With VibeGuard, Legit Security sets a new standard for safeguarding applications built in the AI era—where speed and security must advance hand in hand.
