Insight Technology Inc. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Toshiya Morita, hereinafter "Insight Technology") announces that System EXE Corporation (Headquarters: Chuo-ku, Tokyo; President and Group CEO: Koji Oba, hereinafter "System EXE") has begun offering a "Data Masking Service" that utilizes our high-precision data masking solution, "Insight Masking."
