Precursor, our new continuous behavioral validation engine for bot management, offers visibility into how humans and bots actually interact across the full user journey. By turning session-level behavior into bot detection signals, it identifies advanced automation with higher precision — while reducing friction for legitimate users.
As the Internet evolves, Turnstile does too. Introducing Ephemeral IDs — a new dimension in detecting fraudulent activity, bot or human, that links behavior to a specific client instead of an IP address. This makes Turnstile better for everyone, everywhere.
