Guardrail is targeting a security gap it says legacy tools miss: AI can create data leakage, hallucinated outputs, compliance violations, IP exposure, and unmonitored agent behavior, while its launch release says most existing tools detect known vulnerabilities rather than unknown behavior. The nearly $3 million matters because the company says it has issued patents, government validation, and clients on two continents, and that the capital will support expansion into Asia and Europe and staffing across the business.
