# ISECure Banking API

> ISECure provides a hosted banking-integration API for Finnish corporate bank connections. It connects software products to banks through the corporate Web Services channel and removes bank-by-bank integration, certificate, and key-management work from product teams.

ISECure Oy (Helsinki, Finland) is used by Finnish accounting and ERP software products; bank traffic for hundreds of Finnish companies runs through the service. The product offers a REST API for bank file upload, listing, and download, with OpenAPI documentation and test API access for developer evaluation, plus reliable SFTP/S3 synchronization for file-based workflows that do not use direct REST integration.

Security and operations: private key storage uses AWS KMS encryption in a PCI DSS level system, and the service is hosted separately from the customer software team to reduce exposure and compliance scope. PKI certificate enrollment, renewals, and import/export/storage are handled by ISECure, file materials can require PGP signatures, and bank traffic goes through a hardened interface for sensitive financial operations.

Supported bank connectivity: Nordea, OP, Danske Bank, S-Pankki/LähiTapiola, and Ålandsbanken directly; Handelsbanken, Aktia, POP Bank, Savings Bank, and OmaSP through Samlink and Crosskey connections.

Implementation note: ISECure does not filter or process bank file types as product-specific materials. Bank files pass through the service; bank agreements, credentials, and certificates are still required.
