Zeami Cyber Security Inc. is pleased to announce the establishment of the Layered Domain Observation Center (LDOC), the first specialized security intelligence organization in a private Japanese company.
LDOC is the core organization responsible for collecting, investigating, and analyzing the intelligence data that makes up Zeami Intelligence (ZI), a next-generation security AI platform currently under development.
Background to the creation of LDOC: The fatal flaw in leaks is the delay in discovery
Recent incident investigations have shown an increasing number of cases where it is not the leak itself but the time lag before the leak is noticed that leads to severe damage.

In particular, the following risks have become apparent:
Account information leak via supply chain companies
File leakage from a contractor’s PC
Files posted on leak sites left unattended after ransomware attacks
There are limitations to how much each company can monitor and confirm these signs manually, so a faster and more extensive monitoring system was needed.
Therefore, LDOC was established as a specialized security intelligence unit that extensively investigates and analyzes “signs that exist outside the company,” such as the dark web, leak sites, configuration errors, and leaks via the supply chain.
