[E-Daily Reporter Kim Hyun-ah ] KTCorporation(030200)has launched an AI-based email security service—the first in Korea to obtain the Cloud Service Security Certification (CSAP)—and is now targeting the security market for public and educational institutions.

KTCorporation announced on the 13th that it has launched its “Public-Sector AI Email Security” service, which has received CSAP certification from the Korea Internet & Security Agency (KISA). This marks the first time an email security service combining AI with Advanced Persistent Threat (APT) response technology has received CSAP certification.

AI Filters Out Malicious Emails… 97% Detection Accuracy

KTCorporation AI Email Security is a cloud-based service that uses AI technology to detect and block cyberattacks delivered via email, such as ransomware and phishing emails.

It screens out malicious emails through a three-stage filtering process—spam blocking, AI analysis, and APT response—and delivers only legitimate emails to customers’ mail servers.

Users can selectively apply up to three types of APT analysis engines, and the service maintains a malicious email detection accuracy of over 97% through continuous AI learning. Most analyses are completed within one minute, minimizing delays in email delivery.

Targeting Public Institutions and National Universities… Implementation Without Separate Hardware

Public-Sector AI Email Security primarily targets public institutions and

national universities

, as well as other national educational institutions.

According to the company, the service can be used via the cloud without the need to deploy separate security hardware, allowing organizations to enhance their security levels while reducing the initial investment burden.

CSAP is a leading domestic security certification required to provide cloud services to national and public institutions. Since it can only be obtained by meeting strict information security standards, it plays a role in enhancing the reliability of services for public institutions.

With this certification, KTCorporation plans to accelerate its expansion into the email security market, focusing on public institutions and educational institutions with strict security regulations.

KTCorporation also provides the “One-View” feature to improve the operational efficiency of security personnel.

One-View is a feature that integrates AI analysis and various threat detection results onto a single screen. It allows users to view the basis for detecting malicious behavior, incident history, and risk levels all at once, enabling a rapid response.

Jeon Myung-jun, Executive Vice President and Head of KTCorporation’s Enterprise Services Division, stated, “As cyberattacks via email become increasingly sophisticated, preemptive measures to protect critical information at public institutions are essential.” He added, “Through our AI email security service—the first in Korea to obtain CSAP certification—we will provide a security environment optimized for public and educational institutions and support a secure digital transformation.”
