Email Security Reinvented: How AI is Revolutionizing Digital Defense

“Sending the same email to everyone” are long gone! Attacks are now more targeted, creative, and leverage reputable cloud applications to initiate malicious attacks that evade reputation detection engines.

On average, only 8% of the incoming email traffic of an organization comes from new senders while the remaining 92% is from existing senders. However, if we consider the malicious messages, 90% of them come from new senders that were never seen before.

Although there are mechanisms for email security to minimize these attempts (DMARC compliance), attackers can still reach the end user. AI allows us to understand which brand is being impersonated in the messages by searching for logos and other brand-related information (subject, message text, request, signature, etc.). If something doesn’t match, we generate a signal that will be used as part of the conviction decision.

There are other ways where we leverage AI like QR-code detection, call to action requests, sense of urgency, fake replies, and many other techniques that are used to trick the user. You can count on the Cisco Secure Email Threat Defense to keep your business and information secure.
