Staying ahead of AI-powered brand impersonation
Executive summary: AI has supercharged brand impersonation, with Q2 2024 seeing nearly half of all processed emails containing spoofing or phishing attempts—40% of which were AI-generated.

Consumers are unforgiving when trust is…
Read moreWhat is email spoofing and how can you prevent it?
Executive summary: Email spoofing is a growing cyber threat where attackers forge the sender’s address to impersonate trusted sources, enabling phishing, business email compromise, and financial fraud.

Organizations can mitigate this risk by implementing robust email authentication measures, especially DMARC.…
Read moreWhat is social engineering and how can you prevent it?
Executive summary: Email phishing has evolved and criminals now use social engineering to impersonate executives, suppliers, and even government agencies, persuading recipients to approve payments or disclose credentials.
