Trend Micro has announced that its Cloud App Security tool blocked nearly nine million high-risk email threats in 2018 as attackers continued to evolve their tactics, highlighting the importance of investing in multi-layered protection for online platforms like Office 365.

The findings from Trend Micro’s Cloud App Security report detail how escalating email threat levels are exposing organizations to an increased risk of fraud, spying, information theft, and spoofing. As email remains a staple communication and collaboration tool globally, it is convenient for cybercriminals to leverage this integral, trusted platform for compromising attacks.

 

As the report reveals, email remains one of the most popular threat vectors. In total, the solution detected and blocked nearly 9 million high-risk email threats in 2018. This number was even after Cloud App Security was used as a second filter for emails that passed through Office 365. A Trend Micro customers’ detection result is available in the report.

This underscores that sophisticated, multi-layered security is imperative for cloud-based email security as part of the shared responsibility model.

To improve the tool’s detection rates even further, Trend Micro has added new capabilities that combine Computer Vision and Artificial Intelligence technology to “see” fake websites. This additional technique is applied to suspected phishing emails after filtering based on sender, content, and URL reputation.

The new capabilities sit alongside other Trend Micro email security features. These strategic offerings include AI-powered Writing Style DNA to combat BEC attacks, machine learning-based detection of suspicious email content, sandbox malware analysis, document exploit detection, and file, email, and web reputation technologies. Cloud App Security also leverages the power of the Trend Micro Smart Protection Network, which blocked more than 41 billion email threats in 2018.
