**Summary:** LangSmith’s trust page added “LangSmith Security Overview: Where Your Data Lives and Who Can Reach It (Oct 2026),” covering data handling across Cloud, BYOC and self-hosted deployments for security reviewers. The displayed infrastructure controls now highlight encryption-key and production-database access restrictions instead of network-system authentication and remote-access MFA; the diff does not establish that underlying controls changed. _(machine-written, sol)_
