Email and collaboration platforms are the connective tissue of most businesses and organizations, where information is shared, plans are hatched, and alliances formed. Yet as a human-driven medium, email often represents the ‘weakest link’ in an organization’s security strategy. Indeed, 94% of cyber-threats originate in the email environment.

While traditional gateway tools seek to filter out malicious emails on entry, their reliance on lists of ‘known-bad’ IPs, domains, and file hashes to determine an email’s threat level is extremely limiting. A rule-based approach can often identify known spam and other low-hanging fruit, but it fails to keep pace with attacker innovations. Spear phishing, impersonation attacks, and account takeovers, in particular, remain fruitful ways that cyber-criminals can infiltrate an organization. Increasingly targeted email attacks of this kind, which overcome the limitations of traditional defenses, are a significant challenge for security teams today.
