Email Security: The New Paradigm

发布日期: 2025年1月20日

There has been a significant shift in email platforms where emails which were once deemed too critical a business asset to be hosted on the cloud, are now scattered across most of the major public email cloud platforms (M365 and Google). Likewise, email security has had to and has evolved with new cloud-native email security applications emerging to address the new “cloud” risk.

Threat actors are innovating at a staggering rate with the built-in security of the email platforms offering little protection – they are just not enough. Furthermore, the traditional on-premise email security solutions are struggling to keep pace with the new threats. These solutions (the email platforms along with the traditional on-premise email security applications) as well as the NewGen cloud-native email security solutions, are forced to heavily leverage Artificial Intelligence (AI) to detect and neutralize sophisticated email-based attacks in real time. Using advanced AI-driven threat algorithms and models specific to email, these solutions are able to protect against spam, phishing, malware and more. They also learn users’ writing styles leveraging Natural Language Processing (NLP) to help detect business email compromise (BEC), that is, email impersonation when an account is compromised.? Alongside the security offered within the email platform (capturing approximately 60-70% of the threats if configured correctly), these NewGen email security solutions provide a true defense in depth threat strategy for one of the growing attack vectors being exploited by threat actors.

For businesses looking to stay ahead in the ever-evolving cybersecurity landscape and where emails are deemed a critical business asset, moving to a comprehensive cloud-based email security solution is no longer a choice — it is a necessity!? As the pace of threats accelerate, cloud-native solutions powered by AI are the future of email security.
