Data residency
proof.
Claiming data residency is easy. Proving it independently is harder. Attesto creates verifiable records of data storage location, transfer events, processing chain integrity, and deletion — so organisations can demonstrate data sovereignty without relying on self-reported assertions.
Storage location attestation
Record data storage events with location references — data centre, hosting region, or jurisdiction — as tamper-evident proof objects anchored outside the storage system.
Transfer event proof
Prove that data transfers occurred at specific times, to specific destinations, under specific legal bases — supporting international transfer accountability.
Processing chain integrity
Create a verifiable record of each processing step — transformation, enrichment, analysis — with timestamps and system references.
Deletion and erasure confirmation
Prove that data deletion events occurred at the scheduled time — supporting GDPR Article 17 and contractual data disposal obligations.
Data residency commitments
Record contractual data residency commitments and enforcement events as independently verifiable evidence for customers and supervisory authorities.
Regulatory notification proof
Prove that cross-border transfer notifications, supervisory authority registrations, or standard contractual clause references were in place at the time of transfer.
