Running PII detection locally with the Rampart NER model

SMRTR summary

Arcjet added support for the open-source Rampart NER model to its sensitive information detection feature, enabling apps to detect names, addresses, and SSNs locally — not just structured data like emails and credit card numbers. The 14MB model runs entirely within the app's environment, keeping private data off external servers, with the update shipping in August 2026.
