What is the difference between email threat protection and standard spam filtering?

Standard spam filtering uses rule-based pattern matching to block unsolicited bulk email – primarily marketing messages and obvious scam attempts. Email threat protection is a broader, deeper capability. It addresses the full spectrum of email-borne attacks: spear-phishing, business email compromise, malware delivery, ransomware, account takeover, and genAI-crafted impersonation attacks. Where spam filtering asks “is this unwanted?”, email threat protection asks “is this malicious?” – and uses machine learning, real-time threat intelligence, URL rewriting, sandboxing, and behavioural analysis to answer that question on every single message, at scale.
