    Misdirected emails are the most common form of enterprise communication security breach. Following a spike in the instance and severity of high profile data breaches, companies are under increasing pressure from clients and regulators to put controls in place to prevent these accidents. Tessian prevents your most sensitive information from ending up in the wrong hands by intelligently scanning outbound emails and warning the sender if they are about to make a mistake, before the email is sent.
