LangChain (LangSmith): Trust page changed
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.

Rewindex commits each page capture it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves these records existed by then and have not been changed since, by anyone, Rewindex included.
