Enhancing Coo Kai with New AI Features for Email Misdelivery Prevention

In a significant advancement for digital transformation in businesses, PSC (Pacific Software Company) announced the integration of AI capabilities into its Coo Kai series of misdelivery prevention tools. Available from November 25, 2025, this innovative feature aims to bolster email security, ensuring that crucial information is safeguarded against inadvertent mishaps.

Overview of the AI Diagnosis Function

Domain Name and Recipient Analysis

The newly added AI functionality intelligently analyzes the email addresses and recipient names within the organization to ensure accuracy. By matching the email address with the corresponding organization name, the system can alert users if a potential misdelivery is detected. This proactive approach helps avert embarrassing and potentially damaging errors that can arise from sending sensitive information to unintended recipients.

File Name and Recipient Analysis

Another exciting feature of the AI function focuses on analyzing file names against recipient names. If discrepancies arise, this system provides warnings, further reducing the chances of miscommunication and mishaps, ensuring that sensitive files are correctly addressed.

Doppelgänger Domain Detection

In an increasingly complex web environment, the threat of phishing attacks via look-alike domains poses a significant risk. Coo Kai's AI now assesses whether the recipient's domain closely resembles a legitimate organization, flagging those that appear suspicious. By identifying potentially malicious domains, businesses can navigate these risks more effectively and protect their interests.

Importance of Compliance in Enterprises

Yuko Nakai, an executive in charge of compliance at PSC, emphasizes the critical nature of preventing email misdelivery. Such errors can lead to serious repercussions, including breaches of data protection laws and potential legal liabilities. To mitigate these risks, Nakai urges organizations to report any incidents swiftly and to implement preventive measures such as regular training sessions and thorough reviews prior to sending sensitive communications. PSC is committed to educating its staff on compliance issues and providing clear guidelines to handle any potential incidents, ensuring that customer trust remains intact.

Understanding Internal Risks

Atsuki Sakae, PSC's executive responsible for internal security, highlights the difference between external and internal security threats. While many focus on external factors, internal errors, such as human mistakes and unauthorized access, constitute a substantial portion of security incidents. Approximately one-third of security incidents stem from human error, reinforcing the need for tools like Coo Kai to mitigate these risks. PSC incorporates multi-factor authentication across devices and conducts regular security tests to ensure comprehensive risk management.

Demand in the Market for Misdelivery Prevention

Takao Nakajima, the head of PSC's Cloud Apps division, notes the growing need for robust misdelivery prevention tools in today’s corporate environment. Misdelivery can undermine customer trust and lead to severe financial consequences, such as diminished stock prices. He emphasizes that the Coo Kai tool is effective not just for external communications but also between subsidiary companies and internal emails. With the added AI diagnostic feature, it rigorously checks for alignment in file names, recipient names, and domains to ensure the highest level of accuracy in communications. Businesses can now expect a greater degree of precision in preventing misdelivery incidents.

Commitment to Customer Success

PSC operates under the guiding principle of '3S For All Customer'—a commitment to customer success, satisfaction, and smiles. The new AI features implemented in Coo Kai further exemplify this commitment, ensuring that users can operate with confidence in their communications.
