Frequently asked questions
Clear answers about B2B Secure File Exchange.
What is B2B secure file exchange?
B2B secure file exchange generally means the controlled transfer of business information between separate organizations, with recipient identity, access conditions and transaction evidence kept around the handoff. That gives the team a more defensible record of the handoff.
For b2b secure file exchange, the practical focus is on files moving between separate organizations rather than treating every file as an open link or an unmanaged attachment. For more detail on the related MX workflow, see MX security and administration features.
The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management. Where the workflow is business-critical, the organization should document who owns the process and who is responsible for reviewing exceptions or incomplete exchanges.
How can companies exchange sensitive files with customers, suppliers and partners without using public links?
MX can support files moving between separate organizations with controls designed around recipient identity, access conditions and a traceable exchange history.
That is useful where customers, suppliers, contractors and partners need to handle technical data, contracts, product information and document packages without losing sight of who received the information and what happened next. For a broader view of the related MX controls, see MX feature set.
The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management. Different transactions can carry different conditions, so routine material does not need to be handled exactly like highly sensitive information.
How does My MX Data verify and control access for external recipients?
My MX Data can restrict an exchange to named or authorized recipients rather than relying on an unrestricted public link. The sender retains a clearer connection between the file, the intended recipient and the access window applied to that exchange.
Recipient selection, permissions, multi-factor authentication and expiry settings can then be combined to shape who can reach the information and for how long. For more detail on the related MX workflow, see file-exchange controls.
The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management. Administrative oversight matters because access can change during a project as people join, leave or move between responsibilities.
Can MX support file exchanges across multi-company projects and supply chains?
Yes. MX is designed for exchanges involving more than one organization, including customers, suppliers, contractors and partners. For more detail on the related MX workflow, see MX security and administration features.
Named-recipient controls, recipient groups, linked transactions and audit history can help keep a complex external workflow more consistent as information moves across company boundaries. The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management.
What audit evidence is retained during a B2B file exchange?
MX records activity associated with file exchanges, giving relevant senders and administrators a clearer history after information has been shared. Notifications can also draw attention to pending downloads, new comments or expiring access without requiring somebody to check each exchange manually.
Records may include uploads, access, downloads, comments, recipient activity, timestamps, transaction history and relevant user or IP details. That history can help a team follow up on incomplete exchanges, investigate unexpected activity and prepare evidence for internal review.
The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management. A transaction record is most useful when it answers practical questions such as who accessed the file, when they did it and whether the current version was downloaded.
Can discussions and file exchanges be kept together in the same controlled workflow?
Yes. MX Conversations can keep file-related discussion connected to the controlled exchange instead of splitting context across inboxes and separate chat tools. For more detail on the related MX workflow, see file-exchange controls. This is useful for project instructions, clarification, delivery notes and approval comments that need to remain tied to the underlying file exchange.
Teams can keep instructions, questions, delivery notes, comments and exchange history closer to the files they relate to. The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management.
How is B2B secure file exchange different from general cloud storage or consumer file-transfer tools?
MX is primarily a secure B2B file-exchange platform, so its purpose is different from a general cloud drive, permanent archive or consumer transfer service.
The emphasis is on recipient identity, access conditions, large-file transfer, transaction evidence and controlled external handoffs rather than broad storage or live document co-authoring. For more detail on the related MX workflow, see secure business data handling. General cloud platforms can be entirely appropriate for storage, synchronization and everyday collaboration, but sensitive external handoffs may call for a more exchange-focused control set.
That distinction matters because a business may use MX alongside an existing storage or collaboration platform rather than replacing it. The NIST Cybersecurity Framework is a useful external benchmark for connecting file-exchange controls with broader cybersecurity risk management.
Can businesses distribute large technical files, datasets or software packages to multiple organizations?
MX can support files moving between separate organizations with controls designed around recipient identity, access conditions and a traceable exchange history. For more detail on the related MX workflow, see secure large-file sharing.
That is useful where customers, suppliers, contractors and partners need to handle technical data, contracts, product information and document packages without losing sight of who received the information and what happened next.
