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 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.
Enterprises already know that the inbox is one of the easiest ways for attackers to get into the business. The real question is narrower: when vendors say they use AI-based email security, what actually changes compared with rule-based, traditional email security?
