Put AI to work.Securely.

AI needs access to your third-party apps to do real work. Obsidian makes that access safe, on two fronts:

AI broke security’s economics in three places.

Agents raised what one mistake can cost. Frontier models cut what an attack costs. And every new AI platform adds to what defense costs. We’re bending all three back.

AI security is not one problem.

Each layer protects a different part of your AI environment.
Obsidian covers the layers where AI does the work: your third-party apps.

Let AI agents work.
Stop the action you can’t undo.

Agents inherit the access of the people behind them and act faster than anyone can review. Obsidian decides each action with full context, so you can say yes to more agents.

Frontier AI finds the attack path. Obsidian cuts it first.

AI attackers don’t need a zero-day. They chain findings your tools rate low (a stale token, a forgotten admin, an over-broad grant) into one route to your data. Obsidian turns thousands of findings into the few fixes that break the most paths.

  • 4,000findings
  • 164combinations
  • 7patterns that
    reach your data
  • 4fixes that
    break them all

The economics, verified.

“Securing third-party apps is different. We're operating within a partner's infrastructure, and getting the knobs and dials right across many platforms is critical. Obsidian gives us the visibility and control to do exactly that, helping us get ahead of issues before they become problems.”

“Obsidian  gives us insights and understanding of what privilege has been granted to other third parties.”

“By connecting Cloudflare to Obsidian’s Policy Decision API, our customers can apply decisions informed by who is behind an agent, what access it holds and what data is involved, at the point where agent traffic already flows.”

“As we roll out AI agents across our engineering teams, we need to be confident that every action an agent takes stays within bounds, not just that the agent has valid access. Obsidian gives us that.”
