Products and Services

As South Korea’s largest cyber security company, the firm played a key role in its country’s national defense against major cyber attacks against the financial and broadcasting industry. In addition, with the high level of Internet connectedness for Korean citizens, AhnLab has developed a great deal of experience and expertise dealing with cyber attacks. The AhnLab Malware Defense System (MDS) is designed to reduce the risk of a targeted Advanced Persistent Threat (APT). AhnLab MDS is an enterprise product combining cloud analytics with prevention for both advanced persistent threats (APTs) and distributed denial of service (DDOS) attacks. It does this via real-time detection of malware and filtering of network traffic. Specifically, the AhnLab Smart Defense (ASD) and Dynamic Content Analysis (DCA) components monitor files for attacks that employ non-executable files. Operationally, the malware analysis follows a progression from signature-based analysis to other behavioral technologies, including support from cloud intelligence and the ability to perform many of the security functions directly in the cloud.
