Legit Security, a leader in AI-native application security, has unveiled VibeGuard, an industry-first solution designed to secure AI-generated code as it is created, while also governing the AI coding agents behind it. The launch comes as enterprises increasingly adopt AI-assisted development, producing code faster than traditional AppSec workflows can review.
“Code is no longer written line-by-line by humans — it’s generated by machines,” said Roni Fuchs, co-founder and CEO of Legit Security. “With VibeGuard, we’re defining what it means to secure AI-native development. For the first time, software can be secure by design, at the point of creation.”
Why VibeGuard Matters
As AI coding agents—like GitHub Copilot, Cursor, and Windsurf—become central to software development, security risks multiply. Prompt injection attacks, unintended data exposure, and misuse of third-party model connection points (MCPs) have emerged as major threats. A recent survey by Legit and Gatepoint Research found that 56% of security professionals cited lack of visibility or control over AI-generated code as their top concern.
VibeGuard moves AppSec from reactive scanning to proactive protection, embedding security directly into AI-integrated development environments (IDEs). By continuously monitoring AI agents, VibeGuard can:
- Secure AI-generated code at creation: Policy-based controls, guardrails, and AI training rules ensure that code meets security standards before it reaches production.
- Protect AI coding agents: Monitors agent behavior, MCP usage, and sensitive data handling, while blocking attacks and governing fleets of AI agents.
- Provide full visibility for AppSec teams: Unifies insight across all AI coding environments, models, prompts, and MCPs, allowing teams to restrict, block, and enforce policies in real time.
Bridging the Speed-Security Gap
With AI accelerating code production, traditional AppSec tools—built for human-written code—struggle to keep pace. VibeGuard closes this gap, enabling organizations to maintain rapid development cycles while mitigating risks at the source.
“AI-powered development is a huge opportunity,” said Nir Yizhak, CISO and VP at Firebolt. “Most of our engineering teams are writing code faster than ever, assisted by AI. VibeGuard gives us the ability to reduce risk while maintaining speed—a critical step forward for secure AI-native development.”
The Bigger Picture
VibeGuard’s launch signals a pivotal shift in application security: protection must evolve alongside the AI-driven creation process. By embedding security directly into AI coding workflows, Legit Security sets a new benchmark for enterprises seeking to balance speed, innovation, and compliance in the era of AI-assisted software development.
