What is Abnormal AI Simple Assessment?

In recent years, there has been a surge in sophisticated attacks that evade traditional email security, such as BEC (Business Email Compromise) and sophisticated phishing. Abnormal AI analyzes sender/receiver relationships and behavioral anomalies to accurately detect attacks that traditional products often miss. Assessments can be implemented with just a three-click API integration. There is no need to change your existing email flow, quarantine emails, or delay emails.

It can "visualize" attacks that slip through existing email security without putting any strain on your system.

Why you need to rethink your email strategy now

Email remains the most popular intrusion method for attackers. Our research has confirmed that approximately one-third of attacks confirmed in Japan in fiscal year 2024 were carried out via email.

In recent years,

• Generative AI makes it easy to create suspicious emails with natural-sounding content
• Legitimate cloud services are being abused, and the sender and URL appear legitimate.
• Increase in sophisticated spoofing attacks that do not involve URLs or attachments, such as BEC

These changes have resulted in an increase in threats that are difficult to detect using traditional email security and are difficult for email recipients to detect themselves.

That's why email policies need to be rethought.

Why Abnormal AI?

While traditional email security relies on signatures for detection, Abnormal AI goes beyond that framework and employs a mechanism that learns from daily email exchanges to detect discrepancies​ ​in human behavior and unusual content.

For example, you can spot the following unusual signs:

• A sudden billing email from someone you don't normally communicate with
• Sending emails from unusual times or locations
• Expressions that exaggerate the sense of urgency
• Unnatural Japanese and sentence structures typical of fraud

This approach allows emails to be evaluated from over 40,000 different perspectives, ensuring that attacks that would be missed using traditional methods are detected.

The assessment not only allows you to understand the actual state of attacks that have slipped through, but also provides functions that significantly reduce the workload of security personnel, such as automatic analysis of emails that have slipped through and automatic creation of training emails.
