Questions people ask
- Is LAC's acquisition by KDDI a sign of weakness?
- The acquisition price of 24.6 billion yen in November 2024 reflects KDDI's valuation of LAC's cybersecurity business, not necessarily weakness. LAC still posted consolidated net income of 1,925 million yen for the year ending March 2024. NRI Secure, by comparison, remains under Nomura Research Institute's ownership without a similar recent ownership change.
- How exposed are LAC and NRI Secure to AI replacing their services?
- Both companies are rated as only partly exposed to AI absorbing their core product, since SOC monitoring, incident response, and security consulting still depend on human judgment. Neither LAC nor NRI Secure shows a higher AI exposure than the other based on the available assessment.
- Which company has grown its workforce more, LAC or NRI Secure?
- NRI Secure's Japan headcount grew from about 157 employees in 2021 to about 244 in 2026, showing a clear upward trend. LAC's total consolidated employee count stood at 2,295 as of March 2025, but no prior-year figure is given for comparison.
