Cross-Border Data Transfer

After Schrems II, transfers need supplementary measures.

The problem to solve

Every EU-to-non-EU data transfer under GDPR requires SCC + transfer-impact assessment + data-protection assessment. The legal framework requires controls to mitigate risk; the technical reality is the data crosses + the recipient holds it as plaintext + Schrems II says you have to assume hostile-foreign-surveillance access. The compliance paperwork exists but the underlying risk doesn't actually mitigate.

The solution it enables

Schema-wrap the data flow. The recipient unseals only the fields its schema permits (the actual purpose of the transfer); the other fields stay sealed under keys held in the EU. SCC compliance gains a technical control alongside the paperwork.

What it looks like

An EU-headquartered SaaS provider transfers customer support tickets to a non-EU support hub for 24/7 coverage. Today: tickets land plaintext on non-EU storage; SCC + DPA + Standard Contractual Clauses are in place; compliance signed off; Schrems II residual risk acknowledged in legal but not technically mitigated. After Polymonial: tickets sealed at the EU-hub egress. Non-EU support team's schema unseals issue-resolution fields; PII fields stay sealed in the non-EU storage. The non-EU jurisdiction can subpoena the stored data, but the PII fields stay sealed without the EU-held keys.

“After Schrems II, paperwork needs a technical control. Polymonial keeps the personal data sealed under keys that stay in the EU.”
