# How can I connect SAP Business One with Peakflo via SFTP?
## With Secure File Transfer Protocol (SFTP) integration, you can automate the secure exchange of financial documents between SAP Business One and Peakflo.
### How does SFTP work?
Secure File Transfer Protocol (SFTP) is a robust and secure method for transferring files over a network. Here’s an overview of how SFTP works:
- SFTP provides end-to-end encryption, ensuring that all data transmitted between the client and server is protected from eavesdropping and tampering.
- SFTP uses multiple authentication methods such as:
- Users can authenticate using a username and password.
- More secure than passwords, SSH keys use a pair of cryptographic keys to authenticate users.
- For added security, SFTP supports MFA, requiring users to verify their identity through multiple methods.
- SFTP uses checksums to ensure that the data received is the same as the data sent, preventing corruption during transfer. Moreover, cryptographic hash functions verify the integrity of files by creating a unique hash for each file, which is checked upon receipt.
- SFTP allows administrators to set specific permissions for users, controlling who can read, write, or execute files. Access can be restricted to certain directories, ensuring users can only access the files and folders they are authorized to use.
- SFTP supports various file operations such as copying, moving, and deleting files remotely.
