Building Phishing Detection That Works: 3 Steps for CISOs 

90% of attacks start with phishing. For CISOs, the real pain begins when the SOC cannot quickly tell whether a suspicious alert is just noise or the start of credential theft, account compromise, malware delivery, or wider business disruption.  Modern phishing campaigns are designed to create exactly that uncertainty. QR codes, redirect chains, CAPTCHAs, phishing kits, and AI-generated lures can all hide the real objective until late…
