Aton Signs MOU With Japan's ALQOUZ to Sell PQC Security
South Korean security firm Aton has signed an MOU with Japanese fintech ALQOUZ to enter Japan with post-quantum authentication and anti-phishing services.

South Korean security company Aton has signed a memorandum of understanding with Japanese fintech firm ALQOUZ, led by CEO Atsushi Fujino, to enter the Japanese market. The company plans to find local customers for its post-quantum cryptography (PQC) authentication and anti-phishing services.
ALQOUZ is registered with Japanese financial authorities and supplies AI and big-data solutions to financial institutions. It has experience helping Korean IT firms expand into Japan, and under the deal it will support customer discovery and sales. According to Aton, the agreement was signed in September at its headquarters in Seoul's Seongsu-dong. The two sides will share market and business information, jointly look for prospects, and cooperate on proposals, sales and marketing for Aton's authentication, storage-media, anti-phishing and enterprise security offerings.
Why Japan, why now
Aton points to a surge in attacks on Japanese companies across industries. Data from Japan's Personal Information Protection Commission shows 2,094 reported data leaks caused by unauthorized access between April and October 16 this year, already above the 1,256 recorded in the whole previous fiscal year. The leaked personal data covers about 260 million people, roughly twice Japan's population. Some companies have reset all member passwords after stolen credentials were used to break in.
The government is stepping up its response. On October 9 it asked companies to strengthen countermeasures, including multi-factor authentication. Japan's financial sector had earlier written stronger MFA into supervisory standards after phishing-linked fraudulent securities trades last year. In November last year, Tokyo also set a policy of moving government agencies to PQC by 2035 in principle.
Aton's offering
Aton supplies PQC-based authentication to banks, brokerages, crypto exchanges and fractional-investment platforms, and recently provided PQC-based OTP for the internal systems of Eastar Jet staff. It also sells secure key-storage media and the DefendUs anti-phishing service to banks, and is expanding into managed security through its security center.
CEO Woo Gil-soo said the deal gives the company a foothold in Japan using technology proven in Korean finance, and that Aton will work closely with ALQOUZ on phishing defense and quantum security.
