For AI-Native Startups

Stay secure.

You're building the product. Security shouldn't be a distraction, a delay, or a post-Series-A problem. RAGuard gives AI-native teams enterprise-grade protection from day one — without the enterprise procurement process.

The Problem

Most startups treat AI security as a "later" problem.

This is how companies lose enterprise deals, fail security reviews, and occasionally suffer data breaches that kill customer trust permanently.

The reality: the same prompt injection vulnerability that seems low-risk in beta becomes critical when you have 10,000 users and enterprise contracts. The compliance gap that didn't matter at seed stage blocks your Series B due diligence. The data leak that "probably won't happen" becomes the headline that ends the company.

RAGuard is built for the reality that security can't wait — and the budget reality that enterprise tools can't apply yet.

Security risks that kill startups

Prompt injection on customer data

A single injection in production causes one customer's data to appear in another's session. Deal over.

Failed enterprise security review

"What's your AI audit trail?" You can't answer. The $200K ARR deal goes to a competitor who can.

API key leakage via LLM output

Your model helpfully includes internal credentials in a generated code example. Rotations, incident reports, customer notifications.

GDPR complaint from user

A user's PII appears in responses visible to others. You have no audit trail. The DPA investigation begins.

"We deployed RAGuard to protect our MCP servers. Within 72 hours we had stopped a prompt injection pattern that was causing customer data to leak across sessions — a vulnerability that would have been invisible without inline monitoring. We gained the compliance documentation our first enterprise customer's security review required, and closed the deal."
