How are attackers bypassing traditional email security?

Attackers have developed sophisticated techniques to evade standard email security, including shifting between communication channels (email to SMS to phone), hiding malicious content in legitimate cloud apps like DocuSign, using multiple redirectors to shake off security tools, implementing "Am I Human" verification pages that block security scanners, and embedding text inside images to bypass text analysis. Our clients have found that implementing Zero Trust Architecture principles significantly improves their ability to detect these cross-channel attacks by verifying every access request regardless of which communication platform it originates from.
