Data exchanged is the information shared between users, teams, or systems inside a platform. In collaboration tools, that can include messages, files, comments, links, approvals, and even metadata such as names, timestamps, and permissions. It matters in cybersecurity because every item shared can increase exposure if it contains sensitive business details, credentials, or access paths.
Attackers often target data exchanged to steal information, spread malicious files, or learn how an organization works. A compromised account can turn normal collaboration into a delivery channel for phishing, fraud, or data theft. Defenders reduce risk by limiting who can share what, applying access controls, reviewing permissions, logging activity, and using DLP or content inspection. In practice, the more data a platform carries, the more carefully it must be protected.
