You can use Tessian to protect your organization's email from security threats like phishing, data loss, and accidental misdirected emails. It monitors outbound and inbound email traffic, flags suspicious messages, and prevents employees from sending sensitive data to the wrong recipients. It uses behavioral analysis to detect unusual email patterns without requiring manual rule-setting. Security teams can review flagged emails, set policies, and get visibility into email-based risks across the organization.
