For years, the conversation around AI email security focused on a relatively simple idea: attackers are using AI to create better phishing emails, so defenders need AI to detect them. It’s no longer completely true now…
Email remains one of the main ways businesses exchange contracts, financial information, customer records, employee data, and other sensitive content. But choosing secure email for business is no longer simply a matter of finding a solution or tool that encrypts messages.
Email attacks are no longer arriving as obvious spam or malware. Some attacks contain no malicious attachment; rather, they rely on trust, urgency, payment context, and normal business behavior. For instance, a convincing message may imitate an executive, use a supplier’s compromised account, continue an existing conversation, or persuade an employee to send sensitive information to the wrong person.
Email attacks are now built around timing. A phishing email does not need to sit in an inbox for days to create damage. A user can click in minutes, a finance team can act on a fake vendor request before anyone checks the sender, a malicious link can look harmless at delivery and turn dangerous later, or a reply can come from a compromised account inside a trusted thread and bypass the usual suspicion that comes with a new sender.
