Blockfenders

Blockfenders offers a no-code enterprise data exchange platform that lets two organizations run joint analysis without copying raw records: data stays in each environment, queries are authorized by smart contracts and executed inside a controlled sandbox, and only results travel back rather than row-level detail. Access policies, field-level permissions and call logs are written to tamper-evident records for audit and accountability.

The stack combines end-to-end encryption, data masking and distributed ledgers, using Hedera and Hyperledger to record authorization proofs and data lineage, with a zero-trust model that re-checks every request. It targets regulated sectors such as healthcare, banking and insurance, compressing integrations that once required API work and manual sign-off into configured channels, and reducing dependence on data engineering teams.
