According to the 2020 Verizon Breach and Investigation report, Email is still the most common vector by which organizations are attacked. The importance of implementing email security best practices, therefore, cannot be exaggerated, considering most enterprises rely heavily on this channel for everyday business communications. Unfortunately, threat actors can often trivially exploit the overlooked vulnerabilities of corporate email security through vulnerabilities like the HAFNIUM (CVE-2021-26855), malware or ransomware, phishing attacks, and accidental configurations or employee mistakes.
