Prevent an insider threat with Mimecast

The challenge of stopping insider threat.

While organizations have long been focused on stopping hackers outside the organization from breaching security defenses, most have little protection against an insider threat.

There are at least three types of insider threat profiles. With a Malicious Insider Threat, an employee inside the organization purposely seeks to steal data, leak information or otherwise damage the organization. A Careless Insider Threat occurs when employees don't understand security policies or follow security rules, putting the organization at risk for malware infections and data leaks. And the Compromised Insider Threat involves an employee whose email account has been taken over by hacker through credential harvesting, social engineering, phishing emails or malware in order to steal information or make fraudulent financial transactions.

Almost every insider threat involves email. Email messages are frequently the source of attacks – messages that contain malicious email attachments and URLs are a common technique for launching advanced persistent threats and other attacks. And email is often involved in data leaks, whether malicious or inadvertent. To defend against an insider threat, organizations need insider threat detection for internal email that can quickly identify and remediate an attack or data leak. That's where Mimecast can help.
