About Obsidian Security

Obsidian watches identities, privileges, and agent behavior in Salesforce, Workday, Slack, GitHub, and the AI platforms plugged into them. Runtime controls are meant to stop a Copilot or Claude agent from dumping or deleting production data.

T-Mobile, Workday, and S&P Global are named customers. The Series D pushed the company to a $1.1B valuation.
