CEO GREETING

Countermeasures against cyber-attacks, which have become increasingly sophisticated and complex in recent years, are fraught with problems such as lack of management understanding, lack of expertise, high cost, and increased operational burden after implementation, and the reality is that very few companies are fully prepared despite being aware of the threat.
Founded in 1975 as a consumer electronics export trading company, we began trading in network related equipment, antivirus software and firewall products in 1994, when the Internet was still in its infancy, and were among the pioneers in security countermeasures at that time. We will continue to support highly effective cybersecurity measures by leveraging our deep product knowledge and operational expertise gained from our many years of experience and success.
