Diplomat MFT SFTP Server

SFTP Server Benefits

What is an SFTP Server and Why do You Need One?

An SFTP Server is software that you deploy in an Internet-facing location so that you can host or receive files for secure file exchanges with your clients, customers, suppliers, and other business partners.  External entities connect to your server using any standard SFTP client, using strong authentication and the highest levels of security.  SFTP is the best choice for file exchanges because it supports the highest levels of security for one- or two-factor authentication, data encryption, and integrity verification.  SFTP is also a universal protocol, available on any platform from Windows, Linux, and MacOS to mainframes, IoT, and cloud storage providers.  Furthermore, SFTP is a firewall-friendly protocol, requiring only one hole in the firewall to support all file transfer operations (no more headaches with FTP port ranges!).

An SFTP server provides assurances that an organization’s file exchanges with external parties will be handled  securely across any netwrok  by using the strongest cryptography available to prevent – interception or manipulation by malicious actors via man-in-the-middle attacks.

Coviant Software offers an SFTP server option as a part of the Diplomat MFT family of products. Our SFTP server provides out-of-the-box no-code file transfer process automation, PGP encryption, compression operations, enterprise-grade scalability to support organizations of any size with secure file transfers of any volume, and web-based administration with an easy to navigate user interface.

When combined with our Coviant Software Edge Gateway, the SFTP Server  can remain in your secure back-end network, with the Edge Gateway securely brokering SFTP traffic from your DMZ to the back-end network without requiring any inbound holes in your back-end firewall.  This ensures that no data remains in the DMZ, and all authentication and access control is securely managed by your back-end systems. This defense-in-depth approach significantly increases your company’s security posture.

Furthermore, when combined with the award-winning no-code Diplomat MFT automation platform, the files exchanged with our Diplomat SFTP Server can be automatically PGP encrypted or decrypted; ZIP compressed or decompressed; and/or transferred to the internal or cloud storage systems where they need to go for integration or consumption.  The entire process for file exchanges — send, receive, host, and retrieve — are handled by the Diplomat MFT platform with visibility, management, auditing, and alerting built in.

An SFTP server supports information security and data privacy compliance programs such as HIPAA / HITECH, SOX, GLBA, GDPR, DPA, and PCI-DSS, as well as business-to-business file transfers requiring compliance with organizational standards.
