LAC is a Tokyo Stock Exchange-listed company founded in 1986 that launched security services in 1995. Its core security business is JSOC, a security monitoring centre established in 2002 and described by LAC as one of the largest in Japan, with roughly 1,000 monitoring installations as of April 2024.
Beyond managed monitoring, LAC provides incident response, penetration testing and security consulting for enterprise and government customers. It was named Frost & Sullivan’s Japan Managed Security Service Provider of the Year in 2015.
Innovation Matrix Assessment
Long-running research and service development at JSOC, though innovation is incremental.
Large-scale monitoring and response for Japanese enterprises and government reduces in-house burden.
Public company with thousands of enterprise and government customers (company-reported) and a 2015 Frost & Sullivan award.
Established monitoring-service model rather than category-changing.
Two decades of operational JSOC monitoring and incident-response work for large customers.
Japan's regulatory and threat environment should keep demand for local SOC services durable.
Why CISOs Should Care
Organisations operating in Japan get a domestic, Japanese-language SOC and IR capability with deep local threat knowledge.
What Makes It Different
A long-established, domestically focused monitoring centre combined with in-house incident response and consulting under one public company.
The Matrix Verdict
58/100 — INCREMENTAL INNOVATOR
LAC is an Incremental Innovator: a scaled, credible Japanese MSSP whose strength is operational depth and market position more than disruption.
Editorial Note: Claims vs. Verified Findings
Customer counts and JSOC scale come from LAC's own pages (some dated 2017); the 2015 Frost & Sullivan award is the external recognition found.
