# Obsidian Security hits $1.1B valuation with $85M Series D, becomes AI security unicorn

> Obsidian Security, which builds AI-driven defenses for software-as-a-service environments, has raised an 85 million dollar Series D that lifts its valuation past 1.1 billion dollars and into unicorn territory. The round lands amid a striking run for the category, since by Crunchbase's count nearly 40 AI startups reached unicorn status in the first half of 2026, and AI companies now make up more than a quarter of this year's newly minted unicorns. Security is a natural place for that money to flow. The same agentic systems making headlines for breaking out of test environments also expand the attack surface for everyone else, and buyers are willing to pay for tools that watch identities, configurations and data flows in real time. The caution, as always with a frothy funding cycle, is that valuations are outrunning revenue for many of these companies. Obsidian's raise is real and modest by megaround standards, which arguably makes it a healthier signal than the ten-figure rounds grabbing bigger headlines.
