# Obsidian Security Reaches Unicorn Status with $85M Series D

> Obsidian Security has raised an $85 million Series D that vaults it to a $1.1 billion valuation, formally minting the AI-focused security firm as a unicorn. The company's platform uses AI to spot insider threats and protect data across the SaaS applications that modern enterprises run on, and its customer list is the kind that reassures later-stage investors, sixty of the Fortune 500 and more than a hundred enterprises each spending over a hundred thousand dollars a year. The raise fits a clear pattern in this funding cycle, security has become one of the most fundable corners of AI. As companies wire more of their operations to AI systems and SaaS tools, the attack surface grows, and buyers are willing to pay for software that watches it intelligently. Obsidian's traction with large, cautious enterprise customers suggests it has moved past the experimental phase into something businesses actually rely on. The unicorn label is a milestone more than a verdict, but reaching it on the strength of real enterprise adoption rather than hype is the healthier way to get there.
